How to play LEO5 - The Five Lions Game
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.
About LEO5 - The Five Lions Game
Below the largest exchanges, he sees numerous operators competing for relatively small shares of a fast-growing category. “If you get 1% of this market, I think it’s a huge opportunity,” Patel said. “There are a lot of people fighting to get 1%.”
Jefferies estimates exchanges can retain approximately 65% of explicit transaction fees, with the balance distributed across clearinghouses, brokers and liquidity providers. It therefore expects more operators to bring parts of the infrastructure in-house.
For the independent suppliers growing alongside them, however, the opportunity expands with every new exchange, contract and market maker. The consumer-facing platforms may attract the users, but their products cannot trade at scale without the data, liquidity and operational machinery developing behind the screen.

As with PASPA, this matter revolves heavily around federalism versus states’ rights. Traditional sports betting is governed by individual state regulators with varying laws and regulations. Federal derivatives are regulated by the CFTC, which has fully embraced prediction markets under US President Donald Trump after rejecting them in previous administrations.
The web of lawsuits and court rulings involving prediction markets has greatly complicated the issue of jurisdiction. Kalshi has been forced to limit trading in multiple states, most notably Nevada, and the CFTC has gone to unprecedented lengths to protect its licencees. This includes suing nine states directly and issuing emergency orders to reject state mandates.
CFTC Chairman Michael Selig is currently the lone sitting commissioner for an agency that traditionally features a bipartisan group of five. Selig has repeatedly defended both the legitimacy of prediction markets as financial assets and the role of the CFTC in overseeing them. The CFTC under his direction has embarked on a series of rule proposals regarding prediction markets, although detractors argue that the proposed changes still allow for sports contracts and in some ways could be seen as a tightening of the belt to make a Supreme Court review look more favourable.
