On 26 February 2026, Flutter — the world’s largest online betting company and owner of FanDuel — forecast 2026 profit growth of just 4%, roughly $500m below what analysts expected, and its shares fell more than 9% after hours. It was the clearest signal yet that the traders who spent the year betting against gambling stocks had read the board correctly. Flutter has shed over half its market value since January; DraftKings is down more than 30%; Gambling.com cratered 42% in a single week. For the short sellers positioned against them, the collapse has been lucrative.
The deeper story is not that gambling is dying — it is that the house is being out-housed. A new kind of competitor has appeared that takes bets without paying the taxes, holding the licences, or carrying the costs that sportsbooks do. The sceptics saw it first, and the market is now repricing the entire sector around them.
What the shorts saw coming
The bet against the bookmakers rested on a single insight: the sportsbook duopoly’s moat was an illusion. For years, DraftKings and FanDuel were treated as an unassailable pair, the only legal way for an American to bet on a game. That assumption justified rich valuations and years of cash-burning customer acquisition on the promise of an eventual payday.

SubscribeShort sellers wagered the payday would never fully arrive — that competition, regulation and the sheer cost of holding share would compress margins before the profits compounded. In 2026 they were proved right. Even as DraftKings posted its first-ever profitable year, its stock fell, because the market had stopped pricing the past and started pricing the threat.
The prediction-market insurgency
That threat has a name: prediction markets. Platforms like Kalshi and Polymarket let users trade contracts on the outcome of events — sports, politics, the economy — and they have exploded. Prediction markets cleared roughly $25.7 billion in March 2026 alone, nearly 13 times the volume of a year earlier.
The killer detail is regulatory. Prediction markets are overseen as financial derivatives, not gambling, so they sidestep the state gaming taxes and licensing costs that weigh on every sportsbook bet. They are a second on-ramp to wagering that does not pay the toll the incumbents do — the same regulatory-arbitrage logic now reshaping finance, from stablecoins to fast-entry index rules. Faced with it, DraftKings and Flutter have been forced into a humbling response: launching their own prediction-market products to compete with the very format cannibalising their core business.
Why the incumbents can’t easily fight back
DraftKings boss Jason Robins frames prediction markets as a $10 billion opportunity his firm intends to lead. The shorts are betting that “leading” a low-margin, lightly regulated land grab is not the same as protecting a high-margin franchise — and that the transition will cost more than management admits.
The bet that isn’t over
The risk now runs the other way. Both DraftKings and Flutter are still printing profitable quarters, and a sector down 30% to 50% is exactly where contrarian buyers go hunting. A regulatory crackdown on prediction markets — already urged by critics who call them unlicensed casinos — could hand the incumbents back their moat overnight and trigger a brutal short squeeze.
For now, though, the scoreboard favours the bears. They wagered that the most profitable position in a gold rush is not owning a mine but betting against the miners once everyone else has piled in. As the betting industry has just discovered, the surest way to lose money on gambling is to own the companies that run it.
