Polymarket adds MLB, MLS, and La Liga rights as Sporttrade exits sportsbooks

Published May 22, 2026 Updated 18d ago

Polymarket is expanding internationally while building its US sports presence through exclusive prediction market rights deals, according to a LinkedIn post by Kush Desai. The platform secured deals covering Major League Soccer (announced January 26), Major League Baseball (announced March 19), and La Liga (announced April), giving it exclusive US prediction market rights across the three properties. Meanwhile, Sporttrade is dropping its sportsbook partnerships and shifting strategy away from that distribution model, as reported by TradingView and Cryptonews. The divergent moves reflect different approaches by prediction market operators navigating unsettled regulatory definitions.

Why this matters?

Sporttrade's retreat from sportsbook partnerships leaves Polymarket and Kalshi as the only operators with major league distribution deals in the US market. Polymarket must now convert its Serie A, MLS, MLB, and La Liga exclusives into brokerage or venue integrations before Kalshi's Interactive Brokers and Madison Square Garden model captures the NFL season retail flow.

The bigger picture

Gives Polymarket four announced league exclusives this month after Serie A, MLS, MLB, and La Liga, as the platform builds a US sports-rights portfolio to rival Kalshi's Interactive Brokers and venue integrations.
