‘This is an all-out war’: Inside the casino industry’s fight to stop prediction markets
Las Vegas casinos are fighting prediction markets like Kalshi and Polymarket, which are growing rapidly and structured as financial markets. Casinos argue these platforms avoid taxes and regulations, while prediction market supporters say casinos are resisting competition. A court ruled states can regulate prediction platforms as gambling, and lawmakers are introducing bills to limit the industry. Sportsbooks like DraftKings and FanDuel have seen stock declines, partly attributed to competition

The 30-second read
Why it matters
The appellate decision could reshape the U.S. gambling landscape, constraining prediction market operators while potentially strengthening traditional casino operators, affecting related equities.
Market read
Regulatory outcome may depress prediction‑market stocks while offering a tailwind to casino operators, creating short‑term trading opportunities.
What to watch
Prediction platforms might pivot to non‑gambling events or international markets to sustain growth.
Background
Las Vegas casinos face a tourism slump and rising competition from prediction markets like Kalshi and Polymarket, prompting a coordinated legal and lobbying effort that led to a Ninth Circuit ruling allowing states to treat prediction platforms as gambling.
Ticker impact
DraftKings shares have fallen 49% over the past year as prediction markets draw bettors away.
Further downside pressure likely on DKNG stock.
Loss of sports handle to prediction markets reduces betting volume.
Market effects
Casino and sports betting sector faces regulatory headwinds, while prediction market firms may see increased scrutiny.
U.S. Nevada casinos could gain relative advantage; broader US gambling revenues may be protected.
The ruling could set a precedent for US states, influencing global gambling and fintech regulation.
Counterpoint
If courts limit prediction markets, demand may shift to traditional sportsbooks, boosting casino earnings.
