[Kalshi Launches Single-Stock Perpetual Futures Contracts for Apple, Amazon, and AMD] Kalshi has launched single-stock perpetual futures trading, with contracts for Apple, Amazon, and AMD available for trading as of November 5th. Eligible US users can use leverage to go long or short after approval, without holding the stock or rolling over the contract. As of 11:05 PM, the estimated leverage for Apple and Amazon contracts was approximately 4.96x, and for AMD, approximately 3.36x; the 24-hour notional trading volume for the Apple contract was approximately $4.61 million. Leverage levels vary depending on the stock and position size. Regulatory approvals are facing legal challenges. A US federal judge declined to provide an emergency block, but preliminarily ruled that the challengers' argument that the Commodity Futures Trading Commission (CFTC) lacks the authority to approve single-stock perpetual contracts as securities futures products may prevail. This ruling is not final. (Source: The Defiant)
