FMF Takes Kalshi to Court Over Liga MX Trademark Misuse in 2026

Legal Clash Over Sports IP in Prediction Markets

The Mexican Football Federation has escalated its months-long intellectual property dispute with prediction market platform Kalshi by filing suit in federal court. The FMF alleges that Kalshi has systematically used Liga MX trademarks and club names without authorization, creating a direct challenge to sports leagues' ability to monetize and control their branded content in the rapidly evolving prediction markets sector.

What's at Stake

This case marks one of the first major legal confrontations between established sports properties and prediction market operators over intellectual property rights. Kalshi has positioned itself as a leading platform for event prediction contracts, including sports-focused offerings. However, the platform's expansion into Liga MX content—Mexico's premier soccer league—proceeded without securing proper licensing agreements with the FMF, according to the federation's legal claims.

The dispute underscores a critical gap in the prediction markets regulatory framework: while the CFTC has begun establishing guardrails around market manipulation and trading practices, the intersection of sports IP protection and prediction market operations remains largely uncharted legal territory.

Implications Across the Industry

For iGaming and sports betting operators, the FMF action serves as a cautionary tale about the importance of securing comprehensive licensing agreements before launching sports-related products. Other international soccer leagues, sports properties, and organizations are likely monitoring this case closely as they evaluate their own positions regarding prediction markets.

The outcome could establish binding precedent for how sports intellectual property is protected in prediction markets—territory that differs meaningfully from traditional sports betting, where operators typically secure league partnerships and revenue-sharing agreements. A victory for the FMF would likely trigger similar enforcement actions from other sports properties, potentially requiring platforms like Kalshi to either secure licenses or remove sports-branded content from their offerings.

For Kalshi, the lawsuit represents another major legal headwind following recent regulatory scrutiny from the CFTC regarding market manipulation risks and manipulation detection protocols. The company now faces simultaneous pressure from multiple regulatory and enforcement vectors as prediction markets continue to mature and professionalize.
