Sportsbooks remain king this football season, but upstarts are making a run for the money

U.S. NFL wagering activity is forecast to reach roughly $40 billion this season, with regulated sportsbooks accounting for $31.7 billion of handle, up about 8% year over year. Prediction markets are projected to generate $8.4 billion of equivalent NFL activity, or 21% of the combined market, aided by access to states where traditional sports betting remains illegal. Football contract volume on selected prediction exchanges rose to 2.94 billion from Sept. 1-14, nearly 4x the prior-year period, while Kalshi and Polymarket led tracked exchange volume; sportsbooks have so far reported only limited handle disruption except for BetMGM.

Analysis

The economically relevant risk is not handle migration but mix migration: sportsbooks monetize same-game parlays at structurally elevated hold rates, while exchange-style contracts initially monetize transaction fees and liquidity spreads. If combination contracts normalize consumers to a lower-cost substitute, DKNG, MGM/ENT and private FanDuel face a 6-18 month risk of lower promotional ROI, reduced parlay hold, and multiple compression even if total betting demand grows. MGM and ENT are most exposed because BetMGM lacks the standalone U.S. scale, database and product-development budget to absorb another customer-acquisition arms race.

Near term, the clearest listed beneficiaries are distribution platforms rather than the exchanges themselves. HOOD and COIN can add event contracts to high-frequency retail engagement and funded-account conversion, but the revenue contribution is likely immaterial until contract liquidity and state/federal regulatory treatment are settled. DKNG's proprietary prediction offering is strategically defensive: it can preserve customer ownership and create an eventual cross-sell funnel, though it also risks cannibalizing a higher-margin product category.

The contrarian view is that predictions markets remain complementary until they replicate in-play depth, frictionless payments, VIP service and loyalty rewards. The decisive 1-3 month catalyst is whether Super Bowl-period customer overlap rises materially and whether combination-contract pricing produces sustained take-rate pressure; downloads and gross contract volume alone are poor indicators because they do not reveal unique bettors, incentives, or net revenue. A favorable regulatory outcome for exchanges would accelerate substitution, while enforcement, adverse court rulings, or CFTC restrictions would sharply re-rate the threat downward.

Key Decisions for Investors

• Maintain a 3-6 month relative-value position: long DKNG / short MGM (or ENT where borrow is available). DKNG has superior U.S. product scale and a hedge through its own event-contract initiative; MGM/ENT carry disproportionate BetMGM margin and acquisition-cost risk. Exit if BetMGM demonstrates stable or improving U.S. EBITDA guidance while DKNG cuts FY revenue or adjusted EBITDA guidance.
• Use RSI as the preferred watch-list long rather than an immediate prediction-market trade. Its reported resilience implies lower near-term disruption, but initiate only if upcoming results show sustained handle growth with stable marketing expense as a percentage of revenue; a deterioration in either metric would invalidate the insulation thesis.
• For HOOD and COIN, treat event contracts as an engagement optionality catalyst, not a core earnings thesis. Buy only on evidence of disclosed active-user, trading-frequency, or net-revenue uplift from the category; absent segment disclosure, avoid paying a premium multiple for contract-volume headlines.
• Buy a 3-6 month MGM put spread or ENT put spread around earnings only if management identifies continued customer or handle pressure attributable to exchange products. Defined-risk downside protection is preferable to an outright short because a favorable regulatory ruling against prediction markets could reverse the competitive narrative quickly.
