Prediction Markets Are Coming for Sportsbooks. How to Play the NFL Betting Shake-Up
Football season is becoming the biggest proving ground yet for prediction markets. Sports have already emerged as one of the industry’s strongest growth engines, and the 2026 NFL season could show just how much business these platforms can pull away from traditional sportsbooks.
Prediction markets crash the sportsbook
Legal US sportsbooks are projected to take a record $32.3B in NFL bets this season, but prediction markets could see even more activity at $36.8B.
Part of their advantage comes from geography. Prediction markets can reach users in states that still block traditional sportsbooks, opening access to some of the country’s largest betting markets. California and Texas already account for 44% of prediction-market sports volume, according to RotoWire.
That puts DraftKings and FanDuel owner Flutter Entertainment in a tougher spot. Both are developing prediction-market products while protecting their core sportsbook businesses from platforms that can reach customers they cannot.
The NFL season will show how much that gap is worth. If prediction markets keep pulling volume from states where sportsbooks remain locked out, some of the industry’s biggest untapped markets may no longer belong to sportsbooks alone.
The NFL draws a line
The NFL is keeping prediction markets at arm’s length for now. It has rejected partnerships and barred the products from advertising during league broadcasts while renewing its relationships with DraftKings, FanDuel, and Fanatics.
The league is worried about more than competing betting products. Contracts tied to injuries, officiating decisions, or actions controlled by a single player could create new questions around game integrity.
"Given the tremendous uncertainty — from inadequate regulation to legal challenges — we are not ready to enter into commercial partnerships with prediction markets."

That leaves prediction markets in an unusual position heading into the season. NFL games could drive a surge in trading, but the platforms cannot advertise through the league’s most valuable broadcast inventory.
For now, that gives DraftKings and FanDuel some breathing room. Their official NFL relationships still give their sportsbooks access to advertising channels that prediction markets cannot touch.
Regulators may decide the trade
The legal fight is moving to the center of the prediction-market boom. These platforms operate federally as event-contract exchanges, while traditional gambling remains largely under state control. That divide has opened a fight over who gets to regulate sports contracts and where they can be offered.
New Jersey has asked the US Supreme Court to review the legality of those contracts. If the court takes the case, a decision could come as early as June 2027.
The stakes reach well beyond one state. A favorable ruling could give prediction markets a stronger foundation for offering sports contracts nationwide, while an unfavorable one could weaken one of the industry’s biggest advantages over sportsbooks.
States are already pushing back. Kalshi faces restrictions in Arizona, Massachusetts, Maryland, Michigan, Montana, New Jersey, Nevada, and Ohio following successful state lawsuits.
National access is a major piece of the growth story, which makes the legal fight impossible to separate from the investment case.
Spending becomes the signal
Prediction markets are taking a bigger share of the sports advertising market just as traditional sportsbooks pull back. Sportsbook digital ad impressions fell nearly 14% in 2025, while prediction markets accounted for almost 20% of the sports-betting ads consumers saw.
The shift comes with a regulatory wrinkle. More than half of sports-betting ads seen this year came from platforms that did not have to follow state responsible-gaming rules.
That ad mix is important for margins. Customer acquisition can lift volume, but it can also pressure profits if companies spend heavily to chase the same football bettors.
DraftKings and Flutter could spend as much as $400M on prediction-market offerings in the second half of 2026, based on Stifel estimates. That makes marketing discipline a key line item this season.
How you can frame exposure
Public-market investors looking to trade the prediction-market boom still have limited choices. DraftKings is the more direct US sportsbook play, while Flutter Entertainment brings FanDuel’s larger scale as both companies move into prediction markets.
Kalshi and Polymarket are where much of the growth is happening, but neither is publicly traded. The two have raised a combined $5.7B, based on PitchBook data.
Whether that growth comes at the expense of sportsbooks is still unclear. RotoWire’s Bill Speros argues that prediction markets are reaching people in states where sportsbooks cannot operate, which would point to a larger betting audience rather than a straight fight for existing customers.
The NFL could complicate that expansion. Its latest letter asked operators to remove contracts involving player participation, officiating, and events that could be known in advance.
By the Super Bowl, prediction markets will have had a full season to prove they can keep scaling through legal challenges, league resistance, and an increasingly expensive fight for bettors.
