Summary

Kalshi, a major player in the prediction market industry, has reported topping $1 billion in monthly volume, led by a surge in sports-related contracts. Despite this, state regulators in Maryland, Nevada, New Jersey, and Massachusetts have filed lawsuits alleging that Kalshi’s event contracts are unlicensed sports betting. The company counters that it operates under federal oversight by the Commodity Futures Trading Commission (CFTC). Kalshi now holds 62% of the global prediction market, with Polymarket accounting for 37%. The company is expanding its reach further into the sports sector, with increased trading coinciding with the start of the NFL season.
