Aug 18 (Reuters) – Prediction market startup Kalshi filed with the U.S. Commodity Futures Trading Commission (CFTC) on Tuesday to launch equity ​index perpetuals, a type of futures ‌contract that would let traders take leveraged long or short positions on stock market benchmarks such as the S&P 500 without owning the underlying shares.

Here ‌are ​more details:

• The move is ⁠part of Kalshi’s broader ⁠strategy to compete with traditional exchange operators by expanding beyond event contracts into multiple asset classes through perpetual futures.

• Kalshi’s filing ​for equity index perpetual futures would put the prediction market operator in more ⁠direct competition with traditional derivatives ⁠exchanges by offering a product ​that tracks a major U.S. stock indexes without ​a fixed expiration date.

• Perpetual futures, or ‌perps, are derivatives that lack a traditional expiration date, allowing traders to hold positions indefinitely without rolling over contracts.

• Equity index perpetuals ⁠would apply that structure to broad stock market indexes, while allowing investors to use leverage to amplify ⁠exposure to ‌market moves.

• The company, which ⁠allows people to wager on the ​outcome ‌of events including sports and elections, ​also filed ⁠for copper perpetuals.

• Kalshi would not need SEC approval for the equity index contracts because broad-based equity baskets are regulated by the CFTC.
