DUBLIN — The British institutions that backed Flutter Entertainment’s London Stock Exchange debut in 2019 with a thesis built on European betting expertise colonizing America have two trading sessions left. After Friday, that bet settles out.
Flutter (NYSE: FLUT) will delist from the London Stock Exchange effective August 3, retaining only its New York listing. The company cited low London trading volumes and the cost of dual-listing compliance as the operative reasons. The more revealing explanation sits in its fiscal 2025 numbers: the United States generated $7.8 billion in revenue, 42% of the group total, with US adjusted EBITDA climbing 82% to $922 million. London never matched what that kind of growth required from investors.
FanDuel is the engine. Flutter’s flagship US sportsbook holds approximately 44% of US sportsbook gross gaming revenue, ahead of DraftKings at roughly 34% and BetMGM at 14%. Together, FanDuel and DraftKings control more than three-quarters of a market Flutter projects will reach $63 billion in total addressable size – a figure that does not assume every state legalizes sports betting, only that the current pace of adoption continues. Wisconsin joined the legal market this month. Seventeen states still have no form of legal online wagering.
Flutter moved its primary listing to the NYSE in May 2024. Delisting London entirely is the logical endpoint of that decision. The company spent two years as a secondary feature on the LSE, with trading volumes that did not justify the regulatory overhead. Friday puts a formal end to a listing that had become vestigial. In 2024 alone, 88 companies departed or relocated their primary listings away from London, which fell to 20th in global IPO rankings. Flutter is the largest name to follow.
But the Q1 2026 numbers that directly preceded the formal delisting notice do not tell a simple story of dominance. Gambling’s mainstream grip on American life has produced a market where the competitive pressures are intensifying at exactly the moment Flutter is consolidating its investor base around a single exchange. FanDuel’s US revenue grew 6% year-on-year to $1.14 billion, as Yahoo Finance reported. The better-performing line was iGaming – online casino products – which rose 19% to $564 million. Sports betting handle itself declined 9%. That divergence between casino and sportsbook growth rates matters: online casino carries meaningfully higher margins and is not exposed to a bad-beat weekend, a cold streak for favorites, or a single out-of-bracket result.
US adjusted EBITDA fell 26% year-on-year to $119 million despite that revenue growth, as the company absorbed promotional spending in newly opened states. Missouri launched in December 2025; Arkansas followed in March. New-market launches carry temporary negative margins. That is a structural feature of the US expansion model, not a sign of operational weakness – but investors pricing FLUT at roughly $18 billion against $16.4 billion in full-year group revenue are clearly asking how long the reinvestment cycle continues.
The heavier pressure comes from prediction markets. Platforms like Kalshi recorded combined volumes of approximately £40 billion in 2025, offering users contracts priced by market participants rather than traditional oddsmakers. The format is structurally different from fixed-odds sports betting, and its growth has attracted bettors who wager on outcomes – election results, economic data, major sporting events – that fall outside what licensed sportsbooks can offer in most jurisdictions. Sportsbooks are already being reshaped by single-event market moves that prediction platforms can intermediate more efficiently. FanDuel’s answer is FanDuel Predicts, a prediction market platform that generated what Flutter called “modest” revenues in its first full quarter. Flutter has committed between $250 million and $300 million in adjusted EBITDA to building that platform through 2026. Whether that becomes a competitive moat or a second front to manage is a question FLUT’s shareholder base has not yet priced with conviction.
Leadership restructured in May. FanDuel CEO Amy Howe departed. Christian Genetski, the former FanDuel president, took her place. Dan Taylor moved from running Flutter’s international operations to become president of the broader group. Flutter CEO Peter Jackson described the changes as designed to “sharpen our focus on the US sportsbook.” That language arrived in the same reporting cycle when US sportsbook handle fell 9%.
For Flutter’s London-era investors, the returns have been uncomfortable. FLUT shares are down roughly 50% in 2026, a decline that reflects a combination of factors: unfavorable sports results in the fourth quarter of 2025, the margin compression of new-state launches, the upfront cost of the prediction market bet, and a broader market reassessment of whether US sports betting operators will ever translate massive handle volumes into EBITDA multiples that justify the capital deployed. In fiscal 2025, the US market generated $922 million in EBITDA on $7.8 billion in revenue – an 11.8% margin on a business that was supposed to become structurally more profitable as it matured.
The regulatory environment adds its own variable. A pending IRS rule on gambling loss deductions that takes effect for the 2026 tax year could alter how American bettors account for losses against wins – a change the industry has called a “phantom income” problem that may suppress handle in high-volume recreational betting segments. The impact is unquantified. Flutter’s full-year 2026 guidance of $7.795 billion in US revenue does not explicitly model a behavioral response to that rule.
Flutter’s argument – embedded in the NYSE-only decision – is that American investors understand these dynamics better and will ultimately value the business more accurately than a London market that had less at stake in the outcome. The company’s Q1 2026 earnings call, as the official Flutter press release documented, updated full-year guidance to $18.305 billion in revenue and $2.865 billion in adjusted EBITDA – a 1% EBITDA growth projection that reflects the investment drag but not yet the payoff. Whether the NYSE prices those numbers more generously than London did is not a question the delisting itself answers. The answer comes in what FLUT does after Friday, when the last London holder has made their decision.
