Kalshi launched perpetual contracts linked to BNB, Cardano (ADA), Worldcoin (WLD), Aave (AAVE) and Venice Token (VVV) for eligible U.S. traders on Sept. 4, expanding its American Perpetuals lineup. The U.S.-dollar-margined and settled products have no expiration date, support long and short positions, and offer maximum leverage ranging from 1.9x for VVV to 4.5x for BNB. BNB rose more than 5%, briefly reaching about $729 before settling near $723 as trading volume increased 83%, while ADA climbed almost 10% to about $0.222 amid attention on the RealFi mainnet launch scheduled for Oct. 1. Kalshi now lists perpetuals tied to Bitcoin and 17 altcoins, while applications for Stellar, Polkadot and Hedera remain pending with the Commodity Futures Trading Commission. Kalshi integrated BNB Smart Chain support in December 2025, enabling native BNB and stablecoin deposits and withdrawals. The expansion comes as the CFTC seeks dismissal of CME Group's lawsuit challenging the treatment of KalshiEX's Bitcoin perpetuals as futures rather than swaps. CME has until Oct. 2 to oppose the motion, and the court has not ruled on the classification dispute.
