• Palantir CEO Alex Karp is launching a Neurodivergent Fellowship.
• The fellowship is for those who can relate to Karp's body language during a recent viral interview.
• Final interviews will be led by Karp, Palantir said, and applications for the program will open soon.

Palantir is launching a fellowship for neurodivergent individuals after a video of its CEO struggling to sit still went viral.

The software company said in a Sunday X post that it's encouraging those who can relate to Alex Karp being "unable to sit still," or who think faster than they can talk, to apply.

The final round of interviews for Palantir's Neurodivergent Fellowship would be conducted by Karp, the post added.

"The neurally divergent (like myself) will disproportionately shape America's future," Karp said in a statement posted on X by Palantir.

"We see past performative ideologies and perceive beauty in the world that still exists — which technology and art can expose."

Karp added that the large language model landscape is biased in favor of neurodivergent people.

"Palantir will bring your talents to bear on the West's most urgent problems," the statement added.

Launching the fellowship comes just days after Karp's body language during an onstage interview with The New York Times' Andrew Ross Sorkin at the DealBook Summit drew plenty of online attention.

"Every pre-school teacher in America should be required to watch this video of Alex Karp being completely unable to sit still in his chair," wrote Katherine Boyle, a general partner at a16z, in a Wednesday X post.

During the interview, Karp defended the notoriously secretive company's ethics and praised Donald Trump's immigration policies.

In his statement, Karp did not specifically mention any form of neurodiversity, but he has previously said he has dyslexia.

In an interview with Wired published last month, Karp said that "Doing what everybody else wants me to do is much harder for a dyslexic like me than a non dyslexic."

He added: "Maybe I'm not everyone's cup of tea, but I kind of like being me on most days."

Neurodiversity is a broad umbrella, including ADHD, autism, Tourette's syndrome, dyslexia, and dyspraxia.

Palantir said in its post that it would share an application link for the Neurodivergent Fellowship "soon."

• Paramount Skydance got outbid by Netflix for Warner Bros. Discovery's streaming and studio assets.
• The Netflix-Warner Bros. mega-merger is the largest in years and could upend Hollywood.
• Paramount Skydance has launched a hostile bid for the company.

Paramount Skydance isn't ready to give up the fight for Warner Bros. Discovery.

The David Ellison-run company just launched at $30 offer for all of WBD, even though Netflix agreed to buy WBD's streaming and studio assets last week.

Paramount's lawyers sent a letter saying that "WBD appears to have abandoned the semblance and reality of a fair transaction process," CNBC reported on Thursday. That was the first sign that Ellison and company would make a pitch to Netflix shareholders directly.

Warner Bros. Discovery owns the Warner Bros. film studio, HBO, HBO Max, and TV networks like CNN, TNT, and TruTV.

Paramount Skydance controls film studio Paramount Pictures, streamers Paramount+ and Pluto TV, broadcast network CBS, and cable channels like Comedy Central and MTV.

It's the most wonderful time of the year: Wall Street prediction season.

Bank strategists are weighing in on where they see the S&P 500 landing by the end of 2026. BI's Jennifer Sor has a roundup of what the top Wall Street firms are projecting.

My colleague, Joe Ciolli, author of the fantastic First Trade newsletter, has already written extensively about these predictions. I figured it made sense to chop it up with him.

Dan: Before we get into what Wall Street is predicting for 2026, let's get into why (or why don't) these predictions matter in the first place. Do they hold real weight, or is it just another bit of speculation?

Joe: Given the wide range of outcomes, it's a highly speculative exercise. But on a directional basis, it's an important guidepost for investors. The ones that do their homework can compare the various theses and see who they align most closely with, then follow that strategist's calls all year.

Dan: It's like college football's preseason rankings. A helpful guide, but not set in stone. (Look at Penn State, which started the season ranked #2 in the country and finished 6-6. Yikes!)

With that in mind, it's also worth noting that analysts underestimated the S&P's performance over the last few years, which is perhaps why they've gotten so aggressive for 2026.

Joe: Yes, it's very possible that they're overcorrecting after undershooting the S&P 500 the last two years. Wall Street was collectively 18% off the mark in 2024, and while they've been better this year, they're still lagging by 4%. But they have been directionally correct. Ultimately, it's a better move to pick a strategist or two to follow, rather than try to obey the entire hive mind.

Strategist forecasts have been like Indiana football. Picked to finish 20th in the nation, they're now the top-ranked team in the country.

Dan: The other interesting wrinkle is the Fed. We're getting a new chair — Thanks for the memories, Jerome! — and all the potential complications that come with that.

Joe: That's absolutely a key factor, and the top wild card of 2026. There's a growing view that the new Fed chair will do Trump a solid and cut rates at will. That economic stimulus actually underpins the lofty earnings-growth forecasts most major firms have.

But, as Apollo chief economist Torsten Sløk recently highlighted, there's a risk that those assumed rate cuts cause an inflation spike. And what's the best remedy for high inflation? Rate hikes, which could throw a serious wrench into best-laid bullish plans.

Dan: Let's wrap up by throwing our hat in the prediction ring. I love a same-game parlay, so I'll offer a two-in-one pick. The S&P 500 will drop below 6,000 (about a 15% dip from current levels) before ultimately finishing the year above 7,200 (about 5% increase from where we are at). VIX traders, enjoy!

Joe: Wow! I'm going to do something no major Wall Street bank has had the guts to do yet: predict an S&P 500 decline for next year. Under my scenario (let's say 6,850, about 0.2% below current levels), investors won't get as many rate cuts as they're currently banking on, even with a new Fed chair. Like the AI trade, rate-cut expectations are priced to perfection. I think that'll be spoiled by something unforeseen.

And if I end up being wrong, this conversation never happened.

Dan: Yeah, call me Lane Kiffin because I'm already moving on to the next one.

• Uber is launching an insights platform for marketers called Uber Intelligence.
• It has partnered with LiveRamp to aggregate users' data without revealing their identities.
• Uber has said its ad business is on track to generate $1.5 billion in revenue this year.

Uber wants advertisers to level up their marketing by tapping into data on the millions of rides and deliveries its users order every day.

The ride-hailing giant is announcing the launch of a new insights platform called Uber Intelligence on Monday, the company exclusively told Business Insider.

Launched in partnership with the data-connectivity platform LiveRamp, Uber Intelligence will let advertisers securely combine their customer data with Uber's to help surface insights about their audiences, based on what they eat and where they travel.

It uses LiveRamp's clean room technology, which lets companies aggregate their data in a privacy-safe environment, without sharing or seeing each other's raw or personally identifiable customer information.

A hotel brand could use Uber Intelligence to help identify which restaurants or entertainment venues it might want to partner with for its loyalty program, for example.

Uber also hopes the platform can act as a flywheel for its broader ad business. Marketers can use the data clean room for segmentation, such as identifying customers who are heavy business travelers, then targeting them with ads on their next trip to the airport in the Uber app or on screens inside Uber cars.

"That seamlessness is why we're so excited," Edwin Wong, global head of measurement at Uber Advertising, told Business Insider in an interview. He added that the aim is for marketers to begin saying, "'Oh, I'm not just understanding Uber, I'm understanding Uber in my marketing context.'"

Uber's other route to revenue

Uber Intelligence is the latest step in the evolution of Uber's ad business. Uber officially launched its dedicated advertising division in 2022. It offers an array of ad formats in the Uber and Uber Eats apps, on in-car tablets, in emails to its users, and on car tops.

The company said in May that its ad business had reached a $1.5 billion revenue run rate — the figure it has projected to hit by the end of 2025 — which would represent a 60% increase on last year. The company doesn't break out a more specific ad-revenue figure and hasn't provided an update on the run-rate number since May.

Uber Intelligence forms part of a bespoke set of services it offers its top advertisers. Earlier this year, it launched a creative studio where brands can partner with Uber to deliver more bespoke campaigns, such as offering rides to Miami F1 Grand Prix attendees in a luxury vehicle sponsored by La Mer, packed with freebie skincare products.

Andrew Frank, analyst at the research firm Gartner, said the launch of Uber Intelligence is another signal that Uber's ad business is maturing.

"Early-stage ad businesses tend to focus exclusively on selling inventory while more mature ones focus more on delivering differentiated value through targeting and measurement solutions that help brands understand and optimize the impact of their spend," Frank told Business Insider.

Uber's unique source of "terrestrial data" put it in good standing against the likes of Amazon, Google, and other retail media networks that emphasize the value of their data-driven insights, Frank added. However, he said Uber may need to address privacy concerns related to aggregating highly sensitive data in order to maintain consumer trust and to comply with evolving global regulators as a collector of first-party data.

Vihan Sharma, chief revenue officer of LiveRamp, said its platform provides technical guarantees to ensure "zero movement of data."

"The whole objective of a clean room technology is to build trust between data owners and consumers and the advertising ecosystem," Sharma said.

• Business Insider asked three stylists which items to remove from your closet before the new year.
• Casual pieces, like light-wash denim, are falling out of favor as more refined looks take the lead.
• Neutrals are also taking a back seat to richer, more saturated colors that highlight personality.

A new year brings a new wave of trends, and it's often the perfect time to rethink what's hanging in your closet.

With certain styles fading fast and fresh ones taking their place, knowing what to retire can allow you to step confidently into 2026.

To help you navigate these ever-changing trends, Business Insider asked three professional stylists to share which items you should consider clearing from your closet before the end of the year.

Quiet luxury is cooling off as maximalism heats up.

The ultra-minimal, muted aesthetic associated with quiet luxury is losing momentum as shoppers gravitate toward outfits with more personality, Kendra Sharpe, stylist and founder of Kendra Sharpe Styling & Creative, told Business Insider.

"The time of really minimal looks is kind of out, and more maximalist is in," she said.

As a replacement, Sharpe recommends adding eye-catching textures and details, such as faux fur, sequins, sculptural jewelry, or other bold accessories to bring more interest and dimension to your outfits.

Replace your everyday workout leggings with wide-leg knit pants.

Natalie Tincher, principal stylist and founder of BU Style, said the habit of wearing workout leggings for everyday outfits is starting to fade as people seek pieces that feel both comfortable and appropriate across different settings.

"There are a lot of nice options that give you the comfort of your leggings, but also can be styled in a way that feels more respectful of all the settings that we're in," she said.

Instead, Tincher suggested choosing wide-leg or flared knit pants, which offer the same ease but look more intentional for errands, lunches, or casual workdays.

Say goodbye to your slim, tailored coats.

Both Sharpe and Tincher said the trend of overly fitted coats is behind us.

Sharpe recommends swapping straight-line, perfectly tailored blazers for oversized silhouettes. Relaxed, roomy fits, like a sized-up double-breasted jacket or an oversized, slouchy blazer feel more current, she said.

These looser shapes are also more comfortable and make layering much easier, Tincher said.

Combat boots are giving way to sleeker, more sophisticated styles.

Chunky combat boots are starting to feel heavy as footwear trends move toward sleeker, more refined silhouettes, Emmy-award-winning stylist and author of "Color Your Style" David Zyla said.

He suggested replacing them with "something more fashion forward, such as a knee-high or slouchy leather boot, that's just a little bit more elegant."

These taller, softer styles also create a slimmer finish to the leg and pair naturally with the wider pants and cleaner lines that are trending this season, he added.

Monochrome jewelry is being replaced by mixed metals.

Gone are the days of wearing all gold from your earrings to your anklets.

"What's going to be in is mixing your metals," Sharpe said, adding that wearing a blend of silver and gold jewelry can "make you feel a bit more trendy."

As a starting point, she recommends buying a piece of jewelry that's already designed with mixed metals, such as a necklace with gold and silver accents.

The pre-wrinkled look is losing popularity.

Tincher told BI that pre-wrinkled clothes are "really tricky to pull off," adding that "they can look sloppy, and many times, it's very unclear if they are purposefully wrinkled or treated."

To avoid that confusion, she recommends skipping intentionally wrinkled fabrics altogether and choosing materials that create texture in a more polished, intentional way — such as micro-pleats, which add dimension without looking disheveled.

Swap out your light-wash jeans for darker, more polished denim.

Replacing your light-wash jeans with a darker-wash pair is a simple way to elevate your look, Sharpe said, adding that darker denim is easier to dress up and down from the office to drinks with friends.

To add even more interest, she recommends adding a wide-leg pair to your rotation to keep the look current and versatile.

Give your neutrals a break and lean into saturated color.

Similar to the exit of "quiet luxury," soft, basic shades like gray and black are being replaced with brighter colors that help bring more personality to looks, Sharpe said.

Think bold, highly saturated shades, such as cobalt-blue, bright-green, and other vivid tones that instantly energize any outfit, including a classic pair of jeans and a T-shirt.

And to take it up a notch, she suggests pairing a brighter hue with a complementary color to experiment with another trend: color blocking.

Retire your micro bags in favor of roomier, more functional totes.

Zyla said the tiny bag trend is also fading as fashion shifts toward larger, bolder silhouettes.

"Oversized accessories, including larger totes and clutches, are not only on trend, but they're just really practical," he said.

• Elon Musk spent the weekend blasting the EU after regulators fined X over "deceptive" blue checkmarks.
• He boosted posts comparing the EU to authoritarian regimes and calling for exits.
• The backlash followed a $140 million penalty on X that Musk said was a form of political censorship.

Elon Musk spent the weekend bashing the EU.

The billionaire unleashed a barrage of posts on X, boosting claims that cast Brussels as censorious, corrupt, and anti-democratic — just days after the bloc fined his platform €120 million ($140 million) over the "deceptive design" of its blue checkmarks.

In one post, Musk asked followers: "How long before the EU is gone?" AbolishTheEU."

In another instance, he backed a call for binding referendums on whether countries should remain in the bloc, describing it as a "good idea."

He also reshared a meme comparing the bloc to the Nazi regime, to which he replied: "Pretty much."

Musk repeated his long-standing criticism of European regulation, sharing a video of himself describing EU headquarters as a "giant cathedral to bureaucracy" and warning that the continent is exerting a "slow strangulation by overregulation" as he said innovation suffocates under Brussels' rules.

"The EU bureaucracy is slowly smothering Europe to death," he wrote in another post.

His comments came just days after the EU fined X €120 million ($140 million) for what regulators said were "deceptive" verification features that made it hard for users to identify authentic accounts.

'"On X, anyone can pay to obtain the 'verified' status without the company meaningfully verifying who is behind the account, making it difficult for users to judge the authenticity of accounts and content they engage with," the European Commission wrote on Friday.

The penalty followed a two-year investigation under the bloc's Digital Services Act.

Musk has long accused Brussels of trying to "censor" X, and hours before the weekend barrage, he reposted US Vice President JD Vance, warning the EU to stop "attacking American companies."

The European Commission didn't immediately respond to Business Insider's request for comments.

• BNY is adding Google's Gemini 3 to its enterprise AI platform Eliza, the bank said Monday.
• The move focuses on "agentic" AI that supports multi-step financial workflows.
• It comes as Wall Street's AI arms race intensifies among Wall Street banks and investment firms.

The race on Wall Street to deploy AI agents capable of handling end-to-end tasks is intensifying.

On Monday, BNY said it will embed Google Cloud's agentic AI technology — including Google's latest model, Gemini 3 — into the bank's internal AI platform Eliza, named after the wife of bank founder Alexander Hamilton. The upgrade of its technology stack is the latest step the bank — one of New York's oldest operating businesses — is taking to advance its AI ambitions.

By integrating Google Cloud's tech into Eliza — which already draws on multiple large language models — the firm is betting employees will be able to move faster through daily tasks, Sarthak Pattanaik, the bank's chief data and AI officer, told Business Insider. Take the tedious manual work of client onboarding: staff juggle document collection, verify ID and tax forms, locate key details, look up risk information, and log everything into internal systems. He said agentic AI could help orchestrate those steps, break tasks into smaller components, and deliver the required information in a more streamlined flow.

"Eliza, through the agent tech workflow, is able to make the process much more simpler, efficient, and orchestrated, much more seamlessly," Pattanaik said.

Gemini 3, which debuted in mid-November, can interpret text, images, tables, PDFs, and audio together, allowing employees to load mixed financial materials and have the model interpret and synthesize what matters.

BNY's generative AI build-out began accelerating in 2023, and the bank has been keen to position itself as an early adopter of AI. Eliza now supports more than 120 automated tasks. Pattanaik added that nearly the entire firm has completed generative AI and responsible AI training.

In the bank's third-quarter earnings call, BNY CEO Robin Vince told analysts that the bank was leveraging agentic AI to deploy over 100 "digital employees" that are working "side-by-side" with staff on tasks such as payment validations and code repairs.

"We believe our AI opportunity is significant, and we are pursuing it with urgency," said Vince.

Earlier this year, it announced a similar partnership with OpenAI, the maker of the popular consumer-focused large language model ChatGPT. On its website, it says it was "the first major bank to deploy an AI Supercomputer (powered by NVIDIA) to accelerate processing capacity."

Safety protocols

While exciting, its expansion into agentic systems raises questions about how highly regulated institutions like BNY will ensure data privacy. Both BNY and Google emphasized that deploying agentic AI inside a regulated institution requires boundaries around what the technology can see, decide, or escalate.

Pattanaik said deploying agentic AI inside a bank demands strict oversight. He said each agent must pass an internal model-risk review before it goes live and emphasized that the systems are governed by tight access controls that determine what information they are allowed to use.

Once deployed, he added, the team monitors the agent's performance daily and incorporates those results into a continuous feedback loop.

Rohit Bhat, Google Cloud's head of financial services, told Business Insider that Google provides the safety mechanisms that restrict how agents communicate and what data each one can access. Agents have "development kits" and "protocols" to govern their communication with one another, Bhat said.

"The primary purpose of kits and protocols," he added, "is to establish that communication pathway with those boundary conditions of, 'I'm only allowed to talk to this agent for the set of reasons and nothing else.'"

Why Google thinks it can help Wall Street

Major banks are embracing a mix of homegrown and external AI tools. Goldman Sachs has expanded its internal platforms while experimenting with technology from startups like Cognition Labs.

Dealmakers and investors have adopted tools from newer entrants like Hebbia, which offers prompt libraries and deep search. Morgan Stanley has deployed OpenAI technology to assist its financial advisors, while executives at JPMorgan have spoken publicly about the potential for junior employees to manage teams of AI agents.

Bhat said financial firms are becoming an important testing ground for agentic AI because their workflows involve heavy documentation, strict rules, and significant risk management.

Google's pitch is that Gemini can reason through lengthy materials while staying anchored to a firm's internal policies — a prerequisite for deploying agents across custody, markets, or onboarding.

"You need to make sure that whatever these agents are doing is grounded in the business context and in the business specificity," he said. "That requires these models to be able to understand, and then also adhere to, certain policies and the rules," to make sure they meet "the standards that you would want them to."

• My husband and I have been driving cross-country for five years now to spend time with his mom.
• Flying is faster, but driving lets us soak in the scenery and discover new places along the way.
• Each year, we stay with my mother-in-law for a few months, spending time together and slowing down.

For most of our professional lives, my husband Aram and I had to divide our vacation days between our own trips and visiting his family out of state.

But since transitioning to fully remote work in 2020, we've been able to make a trek from Los Angeles to the Detroit suburbs to spend a few months with his mom, Elizabeth, every year.

Driving nearly 2,300 miles is definitely more demanding than a four-hour plane ride, but it has its perks. We can pack as much as we like, play music as loud as we want, and explore places across the country that we might never have visited otherwise.

More importantly, these trips are a chance to spend quality time both as a couple on the road and as a family once we arrive.

It's nice getting to see the country in ways we couldn't on a plane

To make each journey feel fresh, we travel at different times of year and try new routes, including the famed Route 66.

We also switch up how long we stay on the road, depending on our schedules. This fall, we wanted to get to Michigan "fast" so we completed our trip in three days and two nights.

Over the years, we've stayed in dozens of cities, including Las Vegas, Tucson, Santa Fe, Oklahoma City, Boulder, Breckenridge, St. Louis, and Des Moines.

We've gone to a drive-thru wildlife park in Arizona, attended the Utah Shakespeare Festival in Cedar City, and even saw Bob Dylan perform lakeside in Dillon, Colorado. That concert was an unplanned bonus — we just happened to be in town at the right time.

Roadside attractions are one of our favorite parts about driving instead of flying. If a billboard catches our eye and we have time, we'll pull over.

That's how we ended up walking through caves in the Ozarks, visiting the Precious Moments Chapel in Missouri, and touring the tiny Illinois town of Casey — home to the world's largest rocking chair and other oversized objects.

Even getting gas can be an adventure. This year, we had a blast fueling up and walking around Iowa 80, the world's largest truck stop.

We have a home away from home with my mother-in-law

Elizabeth lives on her own in a three-bedroom house, so she let Aram and me make the upstairs level into our own space, with the bedrooms doubling as offices.

Once we arrive, we quickly settle into our daily rhythm and routines. Even when we're working, it's nice to have her near. It's especially comforting to my husband, who's always been very close to his mom.

But make no mistake — it's not like she's bored and just waiting around for us. At 84, she has a livelier social life than we do. Her vibrancy, curiosity, and generous spirit draw people in, and her eclectic group of friends is always in the mix.

My husband and I also appreciate being able to take a break from the hustle and bustle of LA and experience a more relaxed vibe in Michigan.

We enjoy exploring Detroit, as the city and its neighboring areas have plenty of fantastic restaurants, historic landmarks, and cultural sites, like the Detroit Institute of Arts. We also like heading up to Northern Michigan for the charming lakeside towns.

Aside from that, Elizabeth and I love our "girl time," whether it's going out for happy hour and live music, watching the latest fashion shows and travel videos on YouTube, or simply running errands.

As a neat freak, I also enjoy helping her organize the pantry, declutter drawers, and edit her closets. It feels good to do a little spring cleaning any time of year, and she appreciates it.

We know life is precious and time is limited, so we savor our moments together

Driving across the country every year to spend several months with my mom-in-law was not the kind of living arrangement my husband and I ever expected to have.

However, as long as we continue working remotely, we'll keep this tradition alive.

As she always reminds us, "life is a gift," and we should strive to "make more memories" whenever we can.

• Tesla says Grok can now add navigation destinations thanks to a new update.
• Elon Musk's chatbot was integrated into Tesla vehicles in the summer.
• Grok has previously been controversial, going on an antisemitic rant on X earlier this year.

If you own a Tesla, your next road trip could be planned by Grok.

Tesla unveiled its 2025 holiday update over the weekend, and the company said Elon Musk's AI chatbot can now add and edit navigation destinations.

A video demonstration uploaded by Tesla showed the AI assistant, which was built by Musk's AI startup xAI, responding to a voice command and adding multiple destinations around San Francisco to the car's infotainment screen. Grok was first integrated into Tesla vehicles in July.

The new feature, which the automaker said would turn Grok into "your personal guide," is the latest sign of the increasingly close integration between Tesla's vehicles and Musk's AI chatbot.

Musk announced that Grok would be coming to Tesla EVs in July, shortly after the AI model went on an antisemitic rant on X in which it praised Adolf Hitler.

Since then, Grok has attracted headlines for insisting that Musk is in better shape than LeBron James and reportedly revealing the home addresses of everyday people.

Tesla and xAI did not immediately respond to a request for comment from Business Insider.

Grok is only available on certain Tesla vehicles with sufficiently powerful processors. The chatbot can be set to a range of different personalities, including storyteller, assistant, and "unhinged."

The feature update comes as Tesla looks to turn around its sales slump, with the EV maker likely to post declining annual sales for the second year in a row.

It also comes after investors voted on whether Tesla should invest an undisclosed sum in xAI at the company's annual shareholder meeting last month.

While more shareholders voted in favor than against, a large number abstained. Tesla's board said it would, for now, just examine the "next steps" in light of the abstentions.

• 21 people were injured by pepper spray at London Heathrow Airport on Sunday, police said.
• A woman was robbed of her suitcase in a parking garage elevator.
• Passengers faced chaos as roads were closed and trains stopped serving some terminals.

Travellers faced chaos at London Heathrow Airport on Sunday, where police said some 21 people were apparently injured by pepper spray.

London's Metropolitan Police said they were called to a parking garage at Terminal 3 around 8 a.m. after a number of people were sprayed by a group of men who left the scene.

Armed officers arrived and arrested a man on suspicion of assault within nine minutes of the first report, it added.

"At this stage, it's understood that a woman was robbed of her suitcase by a group of four men, who sprayed a substance believed to be pepper spray in her direction," said Commander Peter Stevens.

He added that it occurred in an elevator, and those directly involved are believed to be known to each other.

21 people were treated by the London Ambulance Service, including a three-year-old child, the police said. Five of them were taken to hospital.

While the terminal remained open, the disruption put many people at risk of missing their flights.

Heathrow is the busiest airport in Europe, serving over 80 million passengers last year.

In an X post, Heathrow Airport advised passengers to allow extra time when travelling to the airport and to check with their airline for any questions.

A highway into Terminals 3 and 2 was closed for about an hour before reopening, according to an X post from National Highways.

It then said it closed it again on the airport's request, "due to the amount of vehicles and pedestrians within the tunnel," but reopened within 30 minutes.

The BBC reported that some passengers were seen getting out of cars and walking down a road with their luggage, towards signs that warned "no pedestrians beyond this point."

There were also delays of 45 minutes approaching the airport, according to National Highways, while Elizabeth Line trains stopped serving the terminals for over an hour.
