Confirmed. Kalshi launched the US 500 Perpetual Future on 2026-10-06, describing it as America’s first stock-index perpetual future.
It tracks a proprietary, market-cap-weighted index of 500 large U.S. companies, rather than the S&P 500 itself, and uses a perpetual-contract structure with no fixed expiry.
Reuters reported that the product lets traders take leveraged long or short exposure, while periodic funding payments are designed to keep the contract aligned with its reference index.
