    Sportradar Expands Polymarket Partnership to 20+ Sports Leagues, Adding Bundesliga Streaming and Grand Slam Tennis Data

    Sportradar Group AG (Nasdaq: SRAD) and Polymarket on Thursday announced a sweeping expansion of their data and streaming partnership, extending coverage to more than 20 global sports leagues and competitions representing approximately 300,000 matches per year — and cementing Sportradar's role as the primary data infrastructure provider for the prediction market industry.

    The August 27, 2026 agreement adds exclusive live streaming for the Bundesliga and Euroleague Basketball, official data feeds for all four Tennis Grand Slams, and coverage of the Chinese Basketball Association, the National Basketball League, and UTR Pro tennis events, among others. It builds on an existing relationship that already covered the ATP Tour, Major League Baseball, the NHL, Major League Soccer, and the UFC.

    What's New: Bundesliga, Grand Slams, and 300,000 Matches

    The expansion brings Polymarket US — operated by QCX LLC as a CFTC-designated contract market — access to some of the world's most-watched sports competitions:

    Bundesliga (exclusive streaming): Germany's top professional soccer league will now be streamed directly to Polymarket users trading on match outcomes. Sportradar holds exclusive streaming rights for the Bundesliga within the prediction market category.

    Euroleague Basketball (exclusive streaming): European club basketball's premier competition joins the portfolio with exclusive rights, delivering live game footage alongside the markets being traded.

    Tennis Grand Slams (official data): All four major tennis events — the Australian Open, French Open, Wimbledon, and U.S. Open — are now included under the Sportradar data relationship. Grand Slam data was not part of Sportradar's earlier ATP Tour agreement with Polymarket, as Grand Slams fall outside the ATP's governance structure. The August 27 expansion closes that gap. The timing is notable: the 2026 U.S. Open is already underway, with the women's and men's main draws both in progress.

    International basketball: The Chinese Basketball Association (CBA) and Australia's National Basketball League (NBL) expand global coverage beyond North American leagues.

    UTR Pro tennis: Professional tennis events under the Universal Tennis Rating system round out the tennis offering.

    Combined with the existing ATP Tour, MLB, NHL, MLS, and UFC agreements, the full partnership now spans more than 20 leagues and approximately 300,000 matches annually.

    Building on the ATP Tour Foundation

    Sportradar's relationship with Polymarket grew significantly earlier in 2026, when the two companies announced a data deal covering ATP Tour tennis, MLB, NHL, MLS, and UFC. That agreement gave Polymarket exclusive streaming rights for ATP Tour matches within the prediction market category — the first time a major prediction market platform had offered live streaming tied directly to tradeable contracts.

    The August 27 expansion substantially broadens that scope. Where the original deal focused primarily on North American professional leagues and the ATP men's tour, the new agreement adds major European soccer and basketball, all four tennis majors, and international basketball competitions.

    Ari Borod, President of Sports Business Development at Polymarket, said the expansion gives the platform "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."

    Carsten Koerl, CEO of Sportradar, framed the deal in terms of the company's broader strategy: "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."

    Sportradar as Prediction Market Infrastructure

    A key detail in Sportradar's corporate client list tells the broader story: both Kalshi and Polymarket appear as named global clients. Sportradar now provides data and integrity services to the two dominant U.S.-accessible prediction market platforms simultaneously.

    Kalshi, the leading U.S. prediction market operator with CFTC authorization as both a designated contract market and a derivatives clearing organization, is a separate Sportradar client. While Thursday's announcement covers only the Sportradar–Polymarket relationship, the dual partnership means Sportradar has effectively positioned itself as the foundational data layer across a majority of U.S. prediction market activity.

    That positioning is not accidental. In its second-quarter 2026 earnings, reported August 3, Sportradar's management cited "prediction market expansion" as a key driver of expected second-half revenue acceleration. The company reported Q2 2026 revenue of €378 million, up 19% year-over-year, with adjusted EBITDA of €76 million — also up 19%. Management noted that some prediction market deal revenue had been delayed from Q2 into the second half; the Polymarket expansion announced Thursday is consistent with the acceleration they projected.

    Sportradar's U.S. revenue grew 16% year-over-year in Q2 (22% on a constant-currency basis), despite what the company described as moderating U.S. market conditions in traditional sports betting.

    What the Data Package Includes

    Sportradar's products delivered to Polymarket under the expanded agreement include five distinct components:

    Premium Sports Data and Live Odds: Real-time data feeds and live odds power Polymarket's market creation and settlement process. Accurate, timely official data is foundational for prediction markets — it determines how efficiently contracts price and how reliably they settle after events conclude.

    Audiovisual Content: Exclusive live streaming across multiple leagues, including ATP Tour, Bundesliga, and Euroleague Basketball. Polymarket traders can watch live events directly alongside the markets they're trading — a feature common in European licensed sportsbooks that is now available on a U.S. CFTC-regulated platform.

    Fan Engagement Solutions: Dynamic content including live scores, schedules, and data visualizations designed to deepen user engagement beyond trade execution.

    Marketing Services: Sportradar's customer acquisition services help Polymarket reach sports fans who may not yet be prediction market participants. As the CFTC-regulated prediction market space competes for users with traditional sports betting and fantasy sports, fan-acquisition capabilities become commercially significant.

    Integrity Services: Sportradar's Unified Fraud Detection System (UFDS) AI monitors trading activity for patterns consistent with suspicious behavior or match-fixing. The Sportradar Integrity Exchange (SIE) enables stakeholders across the sports ecosystem to share integrity threats through a secure network. For prediction markets operating under CFTC oversight — and facing ongoing state-level legal scrutiny — a professional integrity monitoring framework provides both operational and regulatory credibility.

    The Prediction Market Context

    The Sportradar expansion arrives during a period of rapid growth and significant legal pressure for the prediction market industry. More than 20 states are currently in litigation with Polymarket or Kalshi over whether CFTC-regulated sports event contracts require state gaming licenses. That legal backdrop makes the infrastructure story more significant, not less: platforms that can demonstrate professional-grade data sourcing, live odds integrity, and monitoring frameworks are better positioned to argue they operate as regulated financial markets rather than unregulated sports books.

    Sportradar's involvement gives Polymarket US access to the same integrity infrastructure used by licensed sportsbooks across Europe and the U.S. — a point that may carry weight in regulatory and legal contexts where market integrity is a central question.

    The expanded partnership also comes as Polymarket US (QCX LLC) prepares for the NFL season opening September 4. The Sportradar relationship already covers MLB, NHL, MLS, and UFC, and the addition of major international leagues broadens the sports portfolio available for market creation heading into the fall sports calendar.

    What This Means for Prediction Market Traders

    For traders on Polymarket US, the practical implications are concrete:

    • More sports, more markets. Official data for 20+ leagues enables Polymarket to create and maintain markets across a broader range of sports with higher settlement confidence.
    • Live streaming while trading. For leagues where Sportradar holds exclusive prediction-market streaming rights — including Bundesliga and Euroleague Basketball — traders can watch live match coverage without leaving the platform.
    • Grand Slam tennis coverage. All four majors are now in the data relationship, meaning Polymarket can offer U.S. Open, Wimbledon, Australian Open, and French Open markets backed by official data feeds.
    • Settlement reliability. Accurate real-time data reduces the risk of settlement disputes and errors — a recurring concern as prediction markets scale to larger contract volumes.

    FAQ

    What is Sportradar? Sportradar Group AG (Nasdaq: SRAD) is a global sports technology company founded in 2001 and headquartered in St. Gallen, Switzerland. It provides data, streaming, integrity services, and analytics to sportsbooks, media companies, prediction market platforms, and sports federations. Its league clients include the ATP, NBA, NHL, MLB, MLS, UEFA, FIFA, and the Bundesliga.

    Is this the same as the Sportradar–Kalshi relationship? No. Sportradar lists both Kalshi and Polymarket as clients, but these are separate commercial agreements. Thursday's announcement covers the Sportradar–Polymarket partnership exclusively. Sportradar has not separately disclosed the terms of its Kalshi arrangement.

    Which Polymarket entity is covered? The announcement involves Polymarket US, operated by QCX LLC as a CFTC-designated contract market. Polymarket US offers sports prediction markets to U.S. users. The global Polymarket platform (polymarket.com) operates separately and is not accessible to U.S. users through the QCX LLC structure.

    What does "exclusive streaming" mean? For leagues where Sportradar holds streaming rights in the prediction market category — including the ATP Tour, Bundesliga, and Euroleague Basketball — no other prediction market platform can offer the same live feed. Polymarket's streaming for those leagues is category-exclusive.

    When does this take effect? The announcement was dated August 27, 2026. The companies indicated the relationship will continue to expand with "additional products, properties, and markets" — signaling that Thursday's announcement reflects the current scope, not a ceiling.
