Kalshi Expands Offerings with New US 500 Perpetual Contracts

Event contract platform Kalshi has introduced 'US 500 Perpetual Futures,' a new type of contract designed for trading on the anticipated performance of the S&P 500 index.

PredictionSites Newsroom · 6 October 2026

Kalshi, a regulated platform for event contracts, has announced the introduction of what it terms 'US 500 Perpetual Futures.' These new contracts are designed to allow participants to trade on the future performance of the S&P 500 index, a well-known benchmark for large-cap US equities. This development marks an expansion of the types of event contracts available on the platform.

Event contracts, also known as prediction markets, allow users to bet on the outcome of specific future events. Unlike traditional futures, which typically involve the delivery of an asset, event contracts settle based on whether a defined event occurs or a certain metric reaches a specified level. Kalshi operates under regulatory oversight from the Commodity Futures Trading Commission (CFTC).

The term 'perpetual futures' often refers to a type of derivative that does not have an expiry date, allowing positions to be held indefinitely. In the context of an event contract platform, this suggests a continuous market for anticipating the direction or level of the S&P 500, rather than single-event predictions.

The addition of these contracts provides another avenue for users to speculate on market movements using Kalshi's regulated framework. Such offerings can attract a wider range of participants interested in expressing their views on broader economic indicators through a structured trading environment.
