A federal judge sentenced Santos to 87 months in prison last April on felony wire fraud and check fraud charges. After Santos served several months in 2025, US President Donald Trump granted the former congressman clemency, resulting in his immediate release.

Santos’ case represents the most severe among four disciplinary settlements announced by Kalshi, which has faced increasing scrutiny concerning insider knowledge risks and event outcome influence by market participants.

“As the category continues to grow, robust integrity safeguards are not simply optional; they are foundational,” Sean Conroy, EVP of rights and partnerships at Genius Sports, said of the launch.

“By bringing together official data, live streaming, league IP, integrity services and the reach of our Legend media network, we are helping Polymarket deliver a differentiated and trusted experience for sports fans across the US.” 

Genius signed deals with both Polymarket and Kalshi in August, to provide real-time event data and league integrity services, as well as streaming services. Fellow data provider Sportradar also announced similar multi-year partnerships with both Kalshi and Polymarket in June.
