Sportradar and Polymarket have expanded their existing partnership, increasing the scope of sports data, streaming content and integrity services available to the prediction market platform. The revised agreement covers more than 20 sports leagues and competitions worldwide and is expected to support approximately 300,000 matches each year.

The latest development builds on a relationship announced earlier in 2026, when Polymarket gained access to official data from several major sports properties, including the ATP Tour, Major League Baseball (MLB), National Hockey League (NHL), Major League Soccer (MLS) and the Ultimate Fighting Championship (UFC).

Under the expanded arrangement, Polymarket will receive additional official data and content from a wider range of competitions spanning soccer, basketball and tennis. Newly added properties include Germany’s Bundesliga, Euroleague Basketball, the Chinese Basketball Association (CBA), Australia’s National Basketball League (NBL), Tennis Grand Slams and UTR Pro events.

Carsten Koerl, CEO of Sportradar, said: “We are pleased to deepen our partnership with Polymarket extending our data and solutions across a significantly broader portfolio of sports. Prediction markets represent a compelling adjacent growth opportunity and Sportradar is cementing its role as the foundational infrastructure powering this ecosystem. Accurate real-time data, premium live content and a robust integrity framework are what allow these markets to price efficiently, settle reliably, and retain the confidence of participants. We look forward to expanding on this foundation with Polymarket as the category continues to develop.”

Expanded Portfolio Adds Data, Streaming and Integrity Tools

The agreement extends beyond access to official statistics. Sportradar will also provide a range of services designed to support market operations and user engagement on the Polymarket platform.

Among the offerings included are real-time sports data and live odds for both pre-game and in-play markets. The company will also supply audiovisual content through its live streaming portfolio, including exclusive streaming rights connected to competitions such as the ATP Tour, Bundesliga and Euroleague Basketball.

Additional fan-focused features will include scores, schedules and data visualizations intended to provide users with more contextual information while participating in prediction markets.

The partnership also incorporates marketing and customer acquisition services aimed at attracting sports-focused audiences. Alongside these commercial tools, Sportradar will deliver integrity monitoring systems, including its Universal Fraud Detection System AI (UFDS AI), which identifies suspicious activity, and the Sportradar Integrity Exchange (SIE), a secure network that allows participants to share information about potential integrity threats.

According to the companies, the collaboration is expected to continue expanding with further products, sports properties and market opportunities in the future.

Ari Borod, President of Sports Business Development at Polymarket, said: “Expanding our relationship with Sportradar across more than 20 leagues and competitions gives Polymarket access to premium sports data, live content and integrity services at an unprecedented scale. We’re excited to continue building on this partnership as we expand our sports offering.”

Prediction Market Sector Continues to Draw Investment

The enlarged agreement arrives as prediction markets receive increasing attention from companies operating in the broader sports ecosystem.

For Polymarket, the addition of hundreds of thousands of sporting events each year significantly increases the volume of markets that can be offered to users. Sports competitions generate a steady flow of outcomes throughout the calendar year, providing a consistent source of events that can be traded and settled.

The inclusion of live streaming rights for selected competitions also broadens the range of content available through the platform. Access to live broadcasts alongside market activity creates a more integrated sports experience for users following events in real time.

The partnership also highlights Sportradar’s growing involvement in the prediction market segment. Earlier in June 2026, the company announced a separate multi-year agreement with Kalshi, another prediction market operator. Under that arrangement, Sportradar agreed to provide sports data and integrity services to the U.S.-based exchange, which operates under regulation from the Commodity Futures Trading Commission (CFTC). Financial details of either agreement have not been disclosed.

The company’s simultaneous relationships with Polymarket and Kalshi position Sportradar as a supplier to multiple participants in the evolving prediction market industry. While the two platforms operate under different regulatory frameworks, both rely on accurate event information, content distribution and market integrity systems.
