Who's Affected
Analysis
For investors in DraftKings (NASDAQ: DKNG) and Flutter Entertainment, the World Cup has delivered a jarring wake-up call. Prediction markets, armed with a friendly federal regulator and a lower-cost exchange model, have seized 27% of sports bets, calling into question the dominant revenue growth narratives that have underpinned these gambling stocks.
The 2026 FIFA World Cup has emerged as a watershed moment for the US sports betting industry, with prediction-market exchanges capturing an estimated 27% of all legal US sports-betting volume during the tournament's first month, according to H2 Gambling Capital. This marks a dramatic leap from just 9% at the start of the year and signals a fundamental shift in how Americans wager on sports. The surge, led by CFTC-regulated Kalshi and crypto-native Polymarket, is reshaping the competitive landscape and threatening the dominance of traditional sportsbooks like DraftKings and FanDuel.

Kalshi, the largest prediction market, has repeatedly shattered its own trading records during the World Cup. Its daily trading volume doubled the peak it hit just a week before the tournament during the New York Knicks' playoff run, and is running at nearly 10 times the levels seen early in 2026. Even more telling, analytics firm Apptopia reports that Kalshi’s mobile app attracted more daily users than either DraftKings or FanDuel for the duration of the tournament. This milestone underscores how quickly prediction markets are converting sports fans from traditional fixed-odds betting to exchange-based wagering on outcomes, player performances, and in-play events.
The regulatory backdrop is crucial to understanding this disruption. Only two years ago, prediction markets were not permitted to offer sports-related contracts at all. That changed after the Commodity Futures Trading Commission (CFTC), their primary federal regulator, signaled a welcoming approach, allowing platforms to list a growing array of sports-event contracts. Last summer, gambling executives brushed off the threat, confident that state-level gambling regulators would erect barriers. Instead, Kalshi and Polymarket have successfully fended off state lawsuits, leaning on CFTC preemption and arguing their products are distinct from traditional sports betting. This regulatory asymmetry gives them a nimbleness that legacy operators, encumbered by state-by-state licensing and tax regimes, cannot easily match.
What to Watch
The financial implications are stark. If prediction markets sustain even a fraction of this World Cup-driven market share, they could siphon billions in annual revenue from major sportsbooks. DraftKings and FanDuel, which have spent enormous sums on marketing and customer acquisition, now face a competitor with lower cost structures and a potentially more engaging product design. Moreover, prediction markets’ exchange model allows for continuous liquidity and the ability to trade in and out of positions, a feature that fixed-odds betting cannot replicate. The comparison is not exact—prediction markets and gambling companies calculate activity differently, and sportsbooks have not yet released recent internal numbers—but the trend is undeniable.
Looking ahead, the World Cup’s domestic spotlights have amplified the momentum, yet the growth appears durable. Aggressive marketing campaigns made prediction-market brands ubiquitous during round-the-clock coverage, introducing millions to the concept. The upcoming NFL season, the largest US betting market, will be a critical test. If prediction markets continue to gain share, we may see traditional bookmakers scrambling to adopt exchange features or acquire promising startups. For now, the CFTC’s light-touch stance remains the wildcard; a policy shift could alter the landscape overnight, but the trajectory suggests prediction markets have passed the point of no return.

How we covered this story
Every story in our finance coverage is assembled from multiple primary sources, cross-referenced for factual consistency, and scored along three independent dimensions: sentiment, operational impact, and source-cluster confidence. Single-source rumors and unverifiable claims do not pass our editorial gate. When a story shows "Verified by N sources" with N≥2, the development is independently corroborated; when N=1, we mark it explicitly so readers can weigh the signal accordingly.
Impact scoring uses a 1-10 scale weighted toward regulatory, financial, and operational consequence rather than coverage volume. A topic that runs in every outlet but moves no real decisions ranks lower than a niche regulatory filing that reshapes how operators in the finance space have to behave. Read our full methodology for the scoring rubric, our glossary for term definitions, and our trends index for the longitudinal view across the beat.
Sources are only linked to a story once they clear our classification pipeline at a minimum 35 percent relevance threshold. According to that methodology, reviewed July 2026, this follows multi-source corroboration standards recommended by journalism research bodies such as the Reuters Institute for the Study of Journalism.
