Kalshi has launched Ethereum perpetual futures in the United States after CFTC approval, expanding its regulated domestic crypto-derivatives lineup beyond the Bitcoin perpetual futures it introduced on June 3, 2026. The Ethereum rollout makes Kalshi one of the first venues offering U.S.-regulated crypto perpetuals in a market long dominated by offshore platforms, and it comes amid broader scrutiny after the CFTC also cleared Coinbase for similar products. Proposed perpetual contracts tied to XRP, Shiba Inu and other altcoins remain under separate regulatory review. The approvals have also triggered criticism from CME Group CEO Terry Duffy, who called perpetual futures "a disaster waiting to happen," warning that leverage, funding costs and auto-liquidation features can create outsized risks for retail traders even as supporters argue that bringing the product onshore could improve oversight.
