Sportradar expands Polymarket data deal to cover six new leagues

The financial terms were not disclosed, which is standard for rights deals at this stage. What is not standard is the scope of what Sportradar is delivering: not just data feeds, but live odds, audio-visual content, fan engagement tools, marketing infrastructure, and integrity services. That last item carries weight that the others do not.

Integrity services, in a prediction market context, mean surveillance — the monitoring of trading patterns against known match-level events to identify bets placed with information that the market doesn't yet have. Sportradar has built that infrastructure across decades of working with regulated sportsbooks. Polymarket is now buying access to it across six additional properties at once, which suggests the platform's internal surveillance team, however capable, concluded that specialist coverage of non-US leagues required specialist tooling. That is an honest conclusion and a significant one.

The consensus read on this deal will be simple: Polymarket is scaling its sports vertical, Sportradar gets a high-profile client, everyone benefits. I think the more important signal is the integrity layer. Polymarket has operated under sustained regulatory attention, and its leadership has made public statements about midterm election market controls. Bringing Sportradar's integrity architecture into non-US sports markets before those markets are large enough to be obviously at risk is exactly the kind of sequencing that regulators notice. It reads less like a commercial expansion and less like a concession, and more like a firm building its compliance case in advance of the argument it expects to have.

The expansion to the Bundesliga and the EuroLeague is not accidental. These are the competitions most actively traded by European users, a population that sits outside the jurisdictional disputes currently consuming Kalshi's legal calendar in US federal courts. Polymarket, with its existing non-US user base, has audience depth in those leagues that no domestic sportsbook can match. Sportradar's data makes that depth tradeable in a structured way.

Management indicated both parties expect to expand the relationship further. The six new properties are not a ceiling.

How do prediction markets like Polymarket use sports data feeds for integrity surveillance?

Prediction markets use sports data feeds combined with integrity services—specialized surveillance infrastructure that monitors trading patterns against known match-level events to detect information-privileged bets before the broader market prices them in. Sportradar provides this monitoring capability across its decades-long relationships with regulated sportsbooks, delivering not just raw data but live odds, audio-visual content, and pattern detection tools that flag anomalous trading activity in real time.

Which sports leagues does Sportradar's expanded Polymarket deal now cover?

Sportradar's agreement with Polymarket now covers the Bundesliga, EuroLeague Basketball, the Chinese Basketball Association, the National Basketball League, tennis Grand Slams, and UTR Pro events, expanding from a previous partnership limited to the ATP Tour, MLB, NFL, MLS, and UFC. The deal includes data feeds, live odds, audio-visual content, fan engagement tools, marketing infrastructure, and integrity services across all six new properties simultaneously.

Why is Polymarket adding Sportradar's integrity architecture to European sports markets specifically?

Polymarket's expansion into Bundesliga and EuroLeague—Europe's most actively traded competitions by European users—signals the platform is building regulatory compliance infrastructure in advance of anticipated jurisdiction disputes. By deploying Sportradar's surveillance capabilities to non-US leagues before those markets reach obvious regulatory risk levels, Polymarket is sequencing its compliance case early, a pattern that regulators typically recognize as preparation for future enforcement questions.

Where can traders execute bets on the newly covered Sportradar-Polymarket sports properties?

Polymarket, a decentralized prediction market platform, is the venue where traders can execute bets on the six newly covered leagues and events under the expanded Sportradar data agreement. Polymarket's existing non-US user base provides significant trading depth in European competitions like the Bundesliga and EuroLeague, populations that domestic sportsbooks cannot easily reach and that sit outside current US regulatory disputes.
