Kalshi Signs Genius Sports Deal, Mirrors Polymarket Move
Back-to-back signings make Genius Sports the default data layer for regulated prediction markets.
Kalshi has partnered with Genius Sports to supply official sports data, integrity services, marketing, and media to its prediction market platform — announced August 5, 2026, one day after Genius struck an identical deal with rival Polymarket, according to SBC News.
Why It Matters
Two of the largest prediction market platforms now share the same official data infrastructure supplier, signalling that the sector is maturing toward the same data-integrity standards that regulate traditional sportsbooks. Official data feeds reduce the risk of manipulation and disputed settlements — a persistent credibility problem for decentralised prediction markets. For bettors, cleaner data pipelines mean faster, more accurate contract resolution. The back-to-back signings also give Genius Sports a commanding position as the default data layer for regulated prediction markets in the US.
Context
Genius Sports holds official data rights for major leagues including the NFL, and its integrity monitoring tools are already standard across licensed sportsbooks globally. Polymarket, despite operating primarily in crypto-native environments, moved first among prediction platforms to formalise a Genius partnership, as reported by SBC News. Kalshi, which gained CFTC regulatory approval to offer event contracts, is the more traditionally regulated of the two — though the SBC News summary notes this partnership differs from Polymarket's in at least one material respect not fully disclosed in the available source.
What's Next
The key milestone to watch is how each platform deploys Genius's integrity monitoring — specifically whether suspicious-activity alerts feed into CFTC reporting obligations for Kalshi. Differentiation between the two deals will likely become clearer when full contract terms are disclosed.
Gambling involves financial risk. Prediction market contracts can expire worthless.
