Prediction Markets Set for $1.1T Sports Betting Opportunity in US
Summary
A Bank of America report estimates that prediction-market platforms in the US could eventually see annual trading volume of about $1.1 trillion for sports-related contracts. Analysts cited in the report expect total contract activity in 2026 to be nearer $100 billion, signalling substantial growth ahead.
Key drivers include Kalshi, which currently dominates the domestic prediction-market space and reportedly accounts for roughly 90% of US activity, with sports-related contracts representing around 80% of its volume. If platforms collect average fees of about 1%, the projected scale could translate into roughly $10 billion in annual revenue — putting prediction markets alongside major online sportsbooks in economic terms.
Prediction markets operate more like financial exchanges (prices set by user demand and positions traded) rather than fixed-odds sportsbooks, attracting experienced bettors and those limited by traditional bookies. Federal oversight allows these platforms to offer contracts nationwide, while many sportsbooks remain restricted by state-level regulation. Platforms often permit participation from users aged 18+, widening the potential audience, and benefit from a cost structure that avoids some state gaming taxes. Despite the growth outlook, legal and regulatory challenges persist in several states.
Key Points
- Bank of America projects a long-term $1.1 trillion annual trading opportunity for US sports-related prediction-market contracts.
- Analysts expect 2026 contract activity closer to $100 billion — significant growth is still required to reach the long-term estimate.
- A 1% average fee on $1.1tn would imply about $10bn in yearly revenue for platforms.
- Kalshi is the dominant US player, estimated to handle ~90% of domestic activity; sports contracts make up ~80% of its volume.
- Prediction markets function like exchanges (market-driven prices, tradable positions), appealing to sophisticated bettors.
- Federal oversight lets prediction platforms operate nationwide, giving them an edge over state-regulated sportsbooks.
- Lower state tax exposure and 18+ participation rules expand addressable market and margin potential.
- The sector faces ongoing legal challenges as some states seek to restrict or reclassify prediction markets.
