NFL bettors move toward Kalshi and Polymarket, leagues hold back
Sports Illustrated compared Kalshi and DraftKings Predictions as event-contract alternatives to traditional sports betting. Separately, an industry report noted some NFL gamblers migrating from sportsbooks DraftKings and FanDuel toward prediction market platforms Kalshi and Polymarket. The coverage arrives as the NFL itself has rejected prediction market partnership deals. The NFL maintains three traditional sportsbook partners for 2026.
The NFL's rejection of prediction market partnerships creates a structural trap for Kalshi and Polymarket. Gamblers may migrate toward their platforms, but the league's guaranteed-fee sportsbook deals lock out the official data and stadium branding that would validate event contracts to mainstream users. Without NFL cooperation, both platforms must rely on slower organic growth and riskier state-by-state legal fights.
The CFTC's informal pressure on Kalshi's NFL player contracts shows federal registration alone cannot protect product lines. Novig's $125 million first-week volume proves sports prediction markets can scale, but its success came from converted sportsbook users and a five-state legal shield that Kalshi and Polymarket lack. Traders face platforms whose sports offerings live under constant threat of league opposition or regulator phone calls.
Kalshi's retreat from NFL player contracts extends a pattern of CFTC-registered platforms pulling sports products under informal agency pressure, not formal enforcement.
