Polymarket US gets Genius Sports integrity monitoring and live-streaming rights

The monitoring hookup means sports leagues and federations get visibility into unusual trading patterns or sudden swings on markets tied to their own events — the exact kind of surveillance tooling that typically has to be in place before a league will let a betting-adjacent platform anywhere near its brand. That’s presumably why ATP, MLB, the Bundesliga, La Liga, the NHL, and UFC were already comfortable extending relationships to Polymarket, whose 2026 World Cup market became one of its largest ever, before this specific deal even landed. Genius Sports already runs official data and integrity monitoring for dozens of leagues worldwide, adding a layer of credibility beyond a typical content-licensing deal — the company is effectively vouching for how the market behaves around that content.

None of it applies to the Polymarket most people have used, though. The agreement covers Polymarket US specifically, the CFTC-regulated entity that operates separately from the offshore platform most international users actually interact with. Genius Sports is also promoting the US service directly as part of the deal.

On the product side, Serie A is the only competition confirmed so far, with Polymarket staying quiet on what else is coming. Genius Sports will supply the official match data used to settle contracts, a detail that matters more than it looks: pulling results straight from the league’s own provider instead of a secondary feed removes a common source of disputes when a game’s outcome is delayed or contested. Polymarket also picked up rights to league names, logos, and other branded material as part of the package.

Bundling a live broadcast with the market itself is a retention move as much as a feature — it removes the moment where a user would normally tab away to watch the game somewhere else, keeping them inside the trading interface for the full match instead of just the pregame odds.
