“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. 

Initial reaction from investors was largely unfavourable. Genius shares plunged 13% on 18 Sept., falling 17% for the week. The data provider closed the session at $5.64 per share, well below the $6.19 price when it announced the Legend acquisition in February.

Hip‑hop producer Jamal “Mally Mall” Rashid was ordered back to federal prison Thursday (Sept. 17), after a Las Vegas judge found he repeatedly violated the conditions of his supervised release.

Rashid received a 17‑month sentence following a hearing in U.S. District Court, where he admitted to a series of breaches that prosecutors said showed he had not reformed.

In 2021, Judge Gloria Navarro sentenced Rashid to 33 months at the Federal Correctional Institution in Sheridan, Ore., followed by three years of supervised release after he pleaded guilty to one count of using an interstate facility in aid of unlawful activity—specifically, a prostitution service.
