Plus500 has launched Kalshi perpetual futures through its US futures broker arm, and says it is the first such broker, excluding Kalshi Prime, to offer them. The FTSE 250 trading group announced the launch today.

Perpetual futures, or perps, are derivative contracts with no expiry date, so a position can be held indefinitely without rolling it over. They historically traded outside US regulatory oversight until Kalshi launched the first perps contract regulated by the US Commodity Futures Trading Commission in May 2026. Kalshi has since added cryptocurrencies, commodities and indices.

Plus500 says it executes, routes, clears and manages risk on its own technology stack. It clears perps directly as a clearing member, a firm that settles trades straight with the clearinghouse, of Kalshi Klear, which the company calls “the world’s only tech-first derivatives clearinghouse”. It already offers Kalshi prediction markets, and perps are available to business clients and to their customers.

Chief executive David Zruia called it “another significant milestone in a year of excellent progress in the US for Plus500”. Kalshi chief executive Tarek Mansour said Plus500 “was the natural choice to support our expansion into perpetual futures”.
