Polymarket launches multi-leg sports contracts and Yahoo Sports partnership
Polymarket launched multi-leg contracts for sports betting on May 22, 2026, allowing users to combine multiple predictions into single wagers — a product structure closer to parlays than the platform's traditional single-event contracts. The crypto-native prediction market simultaneously expanded into MLS markets for the 2026 season, including moneyline, spread, totals, props, and futures, and secured a content distribution or affiliate arrangement with Yahoo Sports that promotes Polymarket for MLB expert picks with logo placement and sign-up calls-to-action. Yahoo Sports analyst Sam McQuillan analyzed the multi-leg launch as reshaping sports betting and challenging competitors. The moves come as Polymarket competes with regulated rival Kalshi and traditional sportsbooks, and amid intensified regulatory pressure including more than 20 lawsuits and cease-and-desist actions targeting the platform.
Polymarket still lacks CFTC registration, so its multi-leg push keeps the platform dependent on offshore sports brokerage while Kalshi and FanDuel Predicts lock down the onshore market.
Any state-level gambling classification loss in Rhode Island, Nevada, or Washington would give Ohio, Pennsylvania, Wisconsin, and Minnesota regulators binding precedent to force geofencing or block operations entirely.
Polymarket joins DraftKings and Kalshi in chasing the sports-parlay market, with all three platforms now offering multi-leg wagers in the same month that the CFTC sued Minnesota over its prediction-market felony ban and Rhode Island added Polymarket to gambling enforcement.
