Kalshi enforced penalties under multiple exchange rules designed to mirror federal market regulations. These include prohibitions on trading when a participant can influence the outcome of an event, trading on material non-public information and engaging in manipulative or fraudulent practices.

The sanctions, effective from 28 August 2026 , bar Santos from any direct or indirect trading access on Kalshi.

Earlier this year, fellow prediction market platform Polymarket also ended its paid relationship with Santos amid a Department of Justice investigation over whether he had placed a wager on his appearance at the same State of Union address.

One day before a primetime showdown between the University of Mississippi and Louisiana State University, the Tunica-Biloxi Tribe of Louisiana announced the launch of a tribal prediction market app. The new app, powered by Kalshi, will be launched through SaltTrade Derivatives, a newly established subdivision of a tribal-owned enterprise.

Through the collaboration, the tribe will draw upon Kalshi’s established infrastructure and market expertise to develop a distinct tribal-owned trading application, said Tunica-Biloxi Chairman Marshall Pierite in a statement.

“This partnership represents exactly the type of opportunity Indian Country should be pursuing, where Tribes are owners, innovators and leaders, not just participants,” he said. “For generations, the Tunica-Biloxi people have adapted, traded and built relationships that allowed our Nation to prosper. This initiative carries that tradition into the modern economy.”

“That dual value is really the point of the deal,” he explains. “Owning a leading local operator gives us direct, ground-level insight into regulatory developments, player behaviour and payment infrastructure across several African markets, insight that is very difficult to build from the outside.

“Over time we expect that knowledge and local presence to help us open conversations with other operators looking to enter or expand in Africa, in the same way our historical B2C experience in Europe underpinned our platform proposition there.
