A Nevada state court has temporarily barred Kalshi from offering multiple event contract categories - including sports - after siding with regulators who say the platform is operating outside Nevada’s gaming framework

Kalshi says it will now preemptively block athletes, coaches, sports officials, and political candidates from trading in markets tied to outcomes they can influence. The move is a direct response to rising scrutiny over insider trading.

A bipartisan Senate bill introduced on March 23 would bar federally regulated prediction markets from offering sports-related event contracts, escalating Washington’s fight with platforms such as Kalshi and Polymarket

Arkansas bettors can now use the two biggest national sportsbook brands after FanDuel and DraftKings entered the state through casino partnerships approved by regulators in late February.

An Israeli journalist says Polymarket-linked bettors sent threats and tried to pressure him into changing a report about an Iranian missile strike near Beit Shemesh.

Kalshi and Polymarket were broadly right on the 2026 Oscars, correctly signaling nearly all of the major winners before the envelopes were opened

Polymarket is defending its decision to host markets on the timing of U.S. strikes on Iran, arguing the contracts can surface “accurate, unbiased forecasts” in moments when information is chaotic.
