Polymarket Becomes the ATP Tour's Official Prediction Market Provider — With Sportradar Supplying Integrity Monitoring
Polymarket has agreed a deal with Tennis Data Innovations, the ATP Tour's data and streaming joint venture, to become the tour's official prediction market provider. Sportradar — the dominant tennis integrity data provider used by UK bookmakers and the Tennis Integrity Unit — will supply official live data, odds, and integrity monitoring. The deal covers 20,000 matches per season. It is Polymarket's second major official data and streaming deal in two days.
Polymarket has agreed a partnership with Tennis Data Innovations (TDI), the joint venture between the ATP Tour and ATP Media Holdings, becoming the tour's official prediction market provider. US users will get live ATP Tour and ATP Challenger Tour streams integrated with real-time trading markets, with official data and odds supplied by Sportradar. The deal covers approximately 20,000 matches per season, including Indian Wells, the Miami Open, the Cincinnati Open, and the Nitto ATP Finals. '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.
For UK readers, the Sportradar component is the most significant structural detail. Sportradar is already the dominant commercial data provider for regulated UK bookmakers' tennis markets — William Hill, Bet365, Betfair, and virtually every other major UK operator settle tennis bets using Sportradar data. Its integrity services arm monitors ATP matches for irregular betting patterns on behalf of the tour and the Tennis Integrity Unit, which was established to combat match-fixing in professional tennis. UK bookmakers have been required to use integrity-monitored official data as a condition of their Gambling Commission licences since the OLGR framework tightened in the mid-2020s. Polymarket, which does not hold a Gambling Commission licence, is now using the same Sportradar infrastructure voluntarily as part of its official tour partnership — bringing its tennis market integrity framework closer to UK regulatory standards than its current legal status would require.
This is Polymarket's second major official data and streaming deal in 48 hours, following the Genius Sports partnership confirmed on 5 August for Serie A and dozens of other competitions. Both deals follow an identical template: official data for settlement, official streaming for a watch-and-trade product, and integrity monitoring integrated at the data provider level. The same Ari Borod quote structure — 'combining live streaming with prediction markets in one place' — appears in both announcements. On the same day as the ATP deal, Polymarket also announced a Yankees stadium sponsorship. Three institutional deals in two days points to a coordinated rollout, not opportunistic one-offs.
The Challenger Tour dimension is particularly notable for UK tennis followers. The Challenger circuit — the tier below the ATP Tour, where prize money is lower and many UK players compete when not in Grand Slam or ATP Tour draws — has historically had the most concentrated match-fixing concerns, as documented in the Tennis Integrity Unit's annual reports. It has also been the hardest circuit to follow via broadcast, given limited mainstream TV coverage. Polymarket's TDI deal covers the Challenger Tour in full, giving it a content library no UK bookmaker or broadcaster currently provides at scale. Twenty thousand matches per season represents near-complete professional tennis coverage. Whether expanded prediction market attention on Challenger-level events increases or decreases integrity risk is precisely the question that Sportradar will now need to monitor in real time — and the answer will be visible in the data before any regulator needs to make a policy decision.

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 defence: 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 authorises 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 for 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 requiring 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.
