Kalshi just posted the kind of opening week that most trading platforms dream about for their first quarter. The platform’s newly launched perpetual futures contracts blew past $1 billion in notional trading volume within seven days of going live, with more than $100 million changing hands in the first 24 hours alone.

That makes perpetual futures the fastest product launch in Kalshi’s history. And it happened in a product category that, until very recently, was entirely off-limits to US traders in any regulated capacity.

From prediction markets to perpetual futures

Here’s the backstory. Kalshi was founded in 2018 and became the first federally licensed US prediction market exchange in 2020. For years, the platform was known for event contracts, letting users bet on things like interest rate decisions, weather events, and election outcomes. Perpetual futures are a very different animal.

A perpetual future, for the uninitiated, works like a traditional futures contract but without an expiration date. Think of it as a leveraged bet on the price of an asset that you can hold indefinitely. In English: you’re speculating on where Bitcoin or Ethereum is headed, with leverage, and you don’t have to worry about your contract expiring on some arbitrary date and forcing you to roll it over.

These instruments are enormously popular outside the US. The global perpetual futures market exceeds $90 trillion in annual volume. But American traders who wanted to participate in a regulated environment were essentially locked out, forced to either sit on the sidelines or venture into offshore platforms with all the counterparty risk that entails.

The Commodity Futures Trading Commission changed that calculus on May 29, 2026, granting Kalshi approval to offer perpetual futures. The platform went live with 13 contracts on June 3, covering major digital assets including Bitcoin (traded under the ticker BTCPERP) and Ethereum.

A billion-dollar validation

Kalshi accumulated a waitlist exceeding 1 million users ahead of the perpetual futures launch. The company’s financials back up the narrative of aggressive expansion. In May 2026, Kalshi closed a $1 billion Series F funding round that valued the company at $22 billion. The platform’s annualized trading volume across all products hit $178 billion.

What this means for investors and the broader market

For institutional investors, the regulated wrapper matters enormously. Large funds, family offices, and registered investment advisors operate under compliance frameworks that generally prohibit trading on unregulated offshore platforms. A CFTC-approved perpetual futures product removes that barrier entirely. The $90 trillion global market for these instruments suddenly has a regulated US on-ramp.
