Kalshi notified the CFTC on September 28 that it would end its Volume Incentive Program on October 13, moving the scheduled termination date forward from October 1, 2027, without explaining the change. The platform recorded $52.98 billion in trading volume in September, while its Ethereum perpetual-contract market saw roughly $5 billion in nearly identical trades that drew CFTC attention. The regulator’s market oversight division warned in August that volume-linked incentives could encourage wash trading, and CFTC Chairman Selig may take action this week over prediction-market promotional activities.
