Polymarket Becomes the ATP Tour's Official Prediction Market Provider — With Sportradar Supplying Integrity Monitoring
Polymarket has signed a deal with Tennis Data Innovations, the joint venture between the ATP Tour and ATP Media Holdings, to become the tour's official prediction market provider. The agreement covers approximately 20,000 matches per season across the ATP Tour and ATP Challenger Tour, with official live data and odds supplied by Sportradar — which will also provide integrity monitoring services. US users will get integrated live streaming alongside real-time prediction market contracts. It is Polymarket's second major data and streaming partnership in two days, following the Genius Sports deal on August 5.
Polymarket has agreed a partnership with Tennis Data Innovations (TDI) — the joint venture between the ATP Tour and ATP Media Holdings that manages official data and streaming rights for professional tennis — making Polymarket the official prediction market provider of the ATP Tour. Under the deal, US-registered Polymarket users will have access to live broadcasts of ATP Tour and ATP Challenger Tour matches integrated directly with trading markets. Official live data and odds will be supplied by Sportradar, TDI's exclusive distribution partner, which will also provide integrity monitoring services for the markets. The agreement covers approximately 20,000 matches per season, spanning the full professional circuit from high-profile Masters events including Indian Wells, the Miami Open, and the Cincinnati Open through to the Nitto ATP Finals and the ATP Challenger Tour. 'By combining live ATP streaming with official data and prediction markets in one place, we're creating a more dynamic product allowing fans to experience and trade on markets relating to the game as it unfolds,' said Ari Borod, Polymarket's President of Sports Business Development.
The Sportradar component is the most significant structural element. Sportradar is the world's largest sports data company and the dominant commercial data provider for professional tennis globally — its integrity services arm already monitors ATP Tour matches for irregular betting patterns on behalf of the tour and the Tennis Integrity Unit, which was established specifically to combat match-fixing in professional tennis. Having Sportradar supply integrity monitoring for Polymarket's ATP markets means the same company that monitors the betting market anomalies detected by traditional sportsbooks will now do the same for prediction market activity. That closes a gap the Group of Copenhagen's World Cup report identified as a structural problem: prediction markets operating without access to the integrity information-sharing infrastructure that governs traditional regulated betting. For the ATP Challenger circuit in particular — where match-fixing concerns have historically been highest, given lower prize money and weaker oversight — real-time Sportradar monitoring is a meaningful safeguard.
The deal is the second major official data and streaming partnership Polymarket has announced in two days. On August 5, Polymarket confirmed a partnership with Genius Sports covering exclusive streaming rights for Serie A and dozens of other competitions, with Genius Sports providing official data for contract settlement and integrity information-sharing with leagues. The ATP Tour deal follows an identical template: official data for settlement, official streaming for the watch-and-trade product, and integrity monitoring integrated at the data provider level. The consistency of the template across two separate partnerships in 48 hours, alongside the New York Yankees sponsorship announced the same day as the ATP deal, points to a coordinated institutional rollout rather than individual one-off agreements. Polymarket is moving through sport-by-sport and property-by-property, acquiring official data rights and the legitimacy that comes with them.
The product implication is the same as the Genius Sports deal, now extended to tennis: a US user can watch a match at Indian Wells, a Masters 1000 event, and simultaneously trade contracts on set result, match winner, or in-play outcomes without switching applications. Twenty thousand matches per season — the full ATP and Challenger circuit — is a substantially larger content library than any US sportsbook offers via integrated streaming. Sportsbooks typically license premium matches and broadcast a fraction of what Polymarket will now have access to through TDI. The Challenger Tour in particular, which has historically been difficult for fans to follow given limited broadcast coverage, becomes accessible through a platform that generates revenue from trading volume rather than subscription or carriage fees. Whether that depth of coverage on lower-profile events increases or decreases integrity risk — more users watching means more market depth, but more market depth on thin-prize-money events is exactly where the Tennis Integrity Unit focuses — is a question Sportradar's monitoring will now have to answer in real time.

Kalshi's Parlays Drive Back-to-Back $5B Days — and Hand Critics Their Strongest Argument
Kalshi traded a record $5.33 billion on November 7 and $5.36 billion on November 8, with multi-leg parlay-style 'combos' making up roughly 75% of both days' volume. Its 30-day volume topped $100 billion. But the parlay dominance cuts against the platform's legal defense: parlays are a quintessential sportsbook product, and the American Gaming Association has told the Second Circuit that parlays make up about two-thirds of Kalshi's volume and should be treated as sports bets. The implied house edge on 10-plus-leg combos is around 25%, undercutting the argument that these are neutral financial instruments rather than gambling.
Cruz Bill Would Require State or Tribal Approval for Sports Contracts — a Bipartisan Legislative Threat Emerges
Senator Ted Cruz, who chairs the Senate Commerce Committee, is preparing a bill that would bar federally regulated prediction markets from offering gambling-tied event contracts, including sports, unless a state or tribal government authorizes them. It would not ban the contracts nationwide but would require platforms to obtain approval jurisdiction by jurisdiction, resembling state-by-state sportsbook regulation. The proposal arrives as Democrats take control of both chambers after the midterms, creating a potential bipartisan reckoning: a Republican committee chair and a newly skeptical Democratic majority both eyeing restrictions on a sector that had relied on federal protection.
CFTC Tells Platforms to Stop Geofencing States — Directly Colliding With State Court Orders
The CFTC issued an interpretation on November 5 of its 'impartial access' core principle, telling regulated exchanges including Kalshi and Polymarket to drop state-by-state geographic blocks within 30 days or explain why they cannot. The demand collides head-on with existing state court orders that require the platforms to geofence: Washington ordered Kalshi to geofence in August, and Michigan ordered it to use licensed geolocation to block the state in September, with a $500,000 daily fine for violations. Chairman Michael Selig framed the interpretation as a uniformity requirement. The platforms are now caught between a federal demand to unblock states and state court orders to block them.
