Kalshi launches perpetual futures tied to US 500 stock index

Kalshi has launched a perpetual futures contract tied to its US 500 index, creating a new product linked to a broad group of major US companies.

Contract tracks 500 leading US companies

The contract follows Kalshi’s US 500 index. According to the available information, that index comprises 500 of the largest companies in the United States.

As a result, the product is connected to an index covering a wide range of large US businesses rather than a single company or a narrower group of stocks. Its underlying reference is the US 500 index itself.

What the launch establishes

The launch confirms Kalshi’s introduction of a perpetual futures contract tied to this index. The defining details available are the contract’s perpetual structure and its link to the US 500 benchmark.

No additional information was provided about pricing, settlement terms, trading activity or the companies included in the index beyond its total size and description as a group of the 500 largest US companies.

Why the underlying index matters

By using the US 500 index, the contract is associated with a benchmark representing a substantial segment of large US businesses. The launch therefore expands Kalshi’s offerings with a product based on an index rather than an individual corporate name.

Further details about how the contract will operate and perform were not included in the announcement.
