Tribal gaming leaders watch prediction markets closely
"For Anisa, the issue is especially close to home. Southern Paiute peoples have called this land home for generations, long before Nevada was a state, long before the Strip existed. Nevada has some of the most robust gaming oversight in the world, yet platforms like Kalshi continue to operate outside the state’s gaming regulatory framework. If tribes and gaming operators are expected to follow established rules, prediction markets should not be allowed to operate under a different standard."
Prediction markets are attracting billions of dollars in activity, but what could they mean for tribal gaming and sovereignty?

Kalshi rejects probe claims amid insider trading debate
Kalshi has pushed back against reports linking U.S. Senator Jim Banks and Indiana State Representative Andrew Ireland to an insider-trading investigation, disputing claims that banks, Irish authorities, or Indiana officials are probing the matter. The dispute comes as prediction markets face growing scrutiny over market integrity, insider trading risks, and regulatory oversight, with Kalshi continuing to emphasize its surveillance and enforcement measures.
This is false. Kalshi is not investigating Sen. Banks or State Rep. Ireland. We have no evidence of suspicious trading activity in this market.
