In the lead-up to the United States and Israel’s attack on Iran, prediction markets saw a frenzy of activity tied to the conflict. Speculators rushed to guess when the first missile strikes would begin and who might be impacted, placing trades worth hundreds of millions of dollars in total. There are already big winners—and some big losers. This weekend, following the death of Iranian Ayatollah Ali Khamenei, Kalshi faced a customer revolt over how it handled a $54 million market about the fate of Iran’s leadership. “People are absolutely livid,” says Kalshi trader Nicholas Mahoney.
The market offered “yes” or “no” contracts on whether Khamanei would be “out” as the nation’s supreme leader. On Saturday morning, while rumors of Khamenei’s death circulated online but an official announcement had not yet been made, Kalshi was promoting the market on social media. After his assassination was confirmed, many traders who had purchased “yes” contracts assumed they had turned a profit—after all, Khamenei was demonstrably no longer the supreme leader.
Instead, Kalshi paused the market for review on Saturday afternoon, then ultimately resolved at the last-traded position prior to his killing. This meant that many people who had purchased “yes” trades did not get the payouts they anticipated. Kalshi declined to comment on the incident before publication. In a statement sent afterwards, Kalshi spokesperson Elisabeth Diana said the company “included every precaution on this market to make sure people could not trade on the outcome of death.” She added “Our rules were clear from the beginning, we never changed them, and we settled based on the rules. We reimbursed all fees and net losses because we thought the UX could have been clearer for users.”
After the initial wave of criticism on Saturday, Kalshi CEO Tarek Mansour noted on social media that Kalshi’s rulebook has always included a “death carve-out” for markets on when leaders will leave office. Derivatives markets in the United States are not legally permitted to offer contracts on assassination. But Kalshi had only added a notice about the carve-out to the webpage for the market after the attack on Iran had begun, which meant that some traders did not see it. The backlash came swiftly. (Sample commentary online: “You literally ruined the entire credibility of your business.”) Some traders threatened class action lawsuits and said they had filed complaints to the Commodity Futures Trading Commission, the government agency that oversees prediction markets.
On Sunday, Mansour stressed that Kalshi had taken a financial hit to try to fix the issue and vowed to ensure that nobody would lose money. “Kalshi incurred a substantial loss to make users whole,” he wrote in a lengthy apology. “I’m sorry for the disappointment. We’ll improve, thank you for bearing with us,” he wrote. Moving forward, Mansour says, Kalshi will make changes to more prominently highlight death carve-outs in similar markets. A source at Kalshi told WIRED the company lost approximately $2.2 million on the incident.
Mansour’s apology hasn’t satisfied some critics. “I defunded my account and deleted the app,” Mahoney tells WIRED. “They should have settled the market how people thought it would be settled.”
Although this was the largest prediction market resolution dispute of its kind related to the war, it wasn’t the only one. Some traders also criticized Polymarket for its approach to a number of markets about the events in Iran. How prediction markets handle sensitive contracts related to world events is an ongoing issue in the industry. Last year, for example, traders protested how Polymarket resolved a popular market about whether Ukrainian president Volodymyr Zelensky, known for his casual outfits, would wear a suit before a certain date.

![Inside the London hacker house taking a stand against founder burnout | TechCrunch
Six twentysomethings in East London have built what they say is the anti-San Francisco hacker house. The goal is a “holistic improvement in life,” rather than “12 weeks, Demo Day is coming,” Rowan Aldean, 26, explained.
Intrigued, I spent an afternoon visiting the house, meeting its residents, and doing a vibe check. I arrived after Aldean escorted me through the clean sidewalks of a new East London development to where the six-story building stood facing the water.
The house is called the London Island Founder House — or “Lift House” — and Aldean and his wife, Zahraa, 22, an upcoming pharmaceutical research PhD candidate, have lived there since May, just a few months after it officially launched in March. Aldean sold his previous company last year for millions, he said, and now runs an “applied AI” startup that helps companies learn how to deploy agents.
Like all hacker houses, Lift House is part startup workspace, part co-living space. The house is named after both its lift — that is, its elevator — and its mission to uplift tech founders, Aldean said. It’s one of the very few co-living hacker houses to exist in London (compared to San Francisco, where dozens — if not hundreds — are scattered around the city at any given time).
Lift House is a bet that U.K. founders can build successful companies without mimicking the over-the-top hustle culture of Silicon Valley.
Founders have described stories of San Francisco hacker houses illegally running in warehouses, throwing full-on galas, or setting up in a tent or espousing punishing, 72-hour sprints typical of the “996” work culture.
“I don’t expect the performative and over-the-top events will be a thing here,” Aldean said, and pointed to one of London’s most successful AI companies, DeepMind. “They’ve won Nobel prizes and built frontier innovation without any song and dance.”
Instead, Lift House is part of a trend called “Londonmaxxing,” in which founders attempt to optimize everything the London tech scene offers. The London ecosystem feels less showy and less startup bro-y than San Francisco, but its founders share similar ambitions: success, wealth, and market domination. London AI startups have raised billion so far in 2026, out of .7 billion raised by all London startups, according to Dealroom. Six companies have raised more than 0 million: Wayve, Superintelligence, ElevenLabs, Recursive, Ineffable Intelligence, and Isomorphic Labs, the latter three of which were founded by DeepMind alumni. The excitement from AI has boosted the morale of the U.K. tech scene, inspiring a new generation of founders, like those in the Lift House, to take big swings.

Journaling vs. demo day
The timeline for living on Lift House is flexible — some people have stayed for a month; others intend to stay for at least six months. They buy their own groceries, Aldean said, although they often cook together and share ingredients. Cleaning is split among the group. Everyone declined to share information about the rent they pay.
The residents of Lift House aim for a balanced approach toward ambition, each one of them tells me — an almost unheard-of idea by San Francisco startup standards.
On Sundays, the group will journal together, a practice introduced by David Amor, 28, who runs a brain coaching and training company, helping founders and business leaders understand more about their brain and how it can help optimize business performance. The idea of journaling is to help everyone track how much time they spent in nature that week, how well they ate, and how much they moved their bodies.
“I’m eating healthier, working out more, and sleeping more,” Luke, 27, who runs an AI-marketing company, said about living in the house. “I always make sure to have lunch now, which is something that is simple, but I wasn’t doing before I lived here.” (Luke asked that his last name be withheld.) Tuesdays evenings are for volleyball, where the founders play on the house team in a local league.
After dinner on other evenings, Wan Ying L, 25, who just left an AI startup and is working on a new idea, might play the piano in the living room. Sometimes the group plays Catan or visits art exhibitions together.
Presence Plumb, 25, is a tech strategist. She likes to host rooftop dinner parties, serving dishes that reflect the different nationalities in the house — from Iraqi to Spanish — while invited founders, researchers, investors, and operators chat about tech trends and investments.
“It’s a bit calmer, balanced, authentic in a way,” she said of people in the London ecosystem. “They don’t want too much of that only startup tech bro vibe. They want a bit of balance.”
Each founder follows their own schedules for a typical workday. Amor, for example, is up by 8 a.m. and gives himself exactly 30 seconds after waking up before jumping into his morning work. “I have a clear objective of ‘this is what I want to do in the first half of the day, when there’s no distractions.’” After his morning work routine, he takes a cold shower, “because it increases your dopamine by 250% and that gives me that motivation, that spark,” he said.

Luke, meanwhile, is up at around 8:30. His co-founder, Varun, 27 (who asked that his last name be withheld), typically travels to the Lift House to co-work, and the duo starts work at around 9 a.m. with a team call.
Aldean rarely wakes before 10 a.m. unless something big is happening, like a “crazy angel [investor] call,” he said. When asked what makes this house uniquely British rather than a wellness-focused Silicon Valley founder house, Aldean joked: “Well, we drink tea together like Brits, and in SF folks just drink filtered coffee.” More seriously, he spoke of how British founders face a different kind of pressure than those in the U.S. They must navigate a cultural aversion to risk, an inclination toward humility, and a shame associated with failure. Instead of forgoing sleep for hustle and grind, they deal with what they call the “tall poppy syndrome,” when the media builds one up only to ruthlessly tear them down should they become too successful, investors and founders say. It makes some founders in the ecosystem wary of displaying too many wins.
Still, Luke said London is a strong choice for an early-stage founder: There’s a good network, ample early capital opportunities, and an option for a life outside of tech. In many ways, it is much more like New York culturally for founders than in San Francisco.
“London is so diverse that if you look properly enough, you’ll always find something fun to get involved with,” Amor added, “whether that’s a founder-run club, wellness events, [or going] to jazz nights.”

Luke and Varun largely avoided venture capital funding by taking advantage of the U.K. government’s SEIS/EIS, which is supposed to help attract more angel investments into local startups. “There’s people who will pay basically the same rate of tax if they give us the money versus if they pay income tax,” Luke explained as another reason he liked starting out in London.
Aldean also feels the London ecosystem is less cutthroat than the Valley. He recalls his days living in a hacker house in the Bay — everyone’s desk had to face the wall, and it was heads-down, product-building. He felt the ecosystem, at times, was too willing to gossip, which is apparently done quite differently in the U.K.
“There’s nothing like ‘oh my god did you hear that the CTO just, like, did this,’” Aldean said. “It’s like you’re always worried,” he said, that someone would spread negative stories, especially if it benefited them.
Aldean also thinks London startups, more than Silicon Valley ones, sell into slow-moving large corporations rather than to each other, meaning one could build without having to kiss up or posture to get their peers to like them.
To the selling point, Varun and Luke mentioned another difference between the U.S. and U.K. ecosystem. “It’s a relatively fleeting market,” Varun said of the U.S. “You get quick wins. Here, it’s hard to close a customer, but if they close, they stay with you longer.”
Coming to America
Eventually, though, the road for many U.K. startups goes straight to the U.S.
In the U.K., founders have access to affordable top talent from universities like Oxbridge and a time zone that makes it easier to work with the rest of Europe, the Middle East, Asia, and parts of North America. In the U.S., however, they have access to the world’s largest economy and, most importantly, a lot of investors willing to write large checks, from pre-seed to growth stages.
“It’s almost like a factory line in a way,” Varun said. “You start here, and then you expand there or vice versa.”
American investors are also playing a role in luring British talent away from the country. I told the Lift House residents about one startup founder who said a top investor wouldn’t even back the company unless she relocated to the U.S. She ended up doing so, though decided to keep her family based in the U.K. to raise her children.
“We had an investor in Miami who said the same thing,” Luke said of an investor trying to get him and Varun to move to the U.S. “It’s quite a common practice.” He and Varun have already begun their U.S. expansion, and despite loving London, the duo hasn’t ruled out moving to the U.S. to be closer to their customers.

That’s the tension bubbling beneath not just the U.K.’s tech ecosystem but most of Europe’s. “I work with a lot of people trying to support the European ecosystem more,” Plumb said.
Yet, founders “talk about London; everyone is bullish on the country until they get the opportunity to leave,” Aldean added.
The Lift House lease has about a year left, and there is sentiment in the house to keep it going for as long as they can. After all, there aren’t too many in London, though the city sees many short-term gatherings, like the Solana Hacker House meet-up series. Some of the more public co-living hacker houses are part of a global chain, like the San Francisco-based network The Residency, which expanded into London last year, and BaseJump, which is announcing a London version of its hacker house program soon.
In 2024, two founders tried the opposite version of the Lift House called “The London Founder House,” which Sifted covered under the headline “The people here don’t want work-life balance.” That home is noted as London’s first-ever hacker house, and though it wound down last year, it left an influence through its concept, events, and connected players around the ecosystem. To even be considered for the London Founder House, one had to have raised at least half a million dollars.
For Lift House, prospective residents need to show a hobby outside their companies and an interest in fitness. It’s the same pitch many in the Londonmaxxing ecosystem are using to keep people from leaving: That here one can have it all.
“The culture is to build something that lasts,” Aldean said, “not necessarily burn out chasing a flash.”
