Kalshi just did something no one else has managed on US soil: launch regulated cryptocurrency perpetual futures contracts. The prediction market platform, already overseen by the CFTC, debuted its BTCPERP contract on May 29, and the market responded with enthusiasm that bordered on frenzy. Over $100 million in notional volume traded in the first 24 hours alone.

Within one week, that figure surpassed $1 billion.

The CME pushback

CME Group CEO Terry Duffy went public with his concerns on June 4, calling Kalshi’s perpetual contracts “a disaster waiting to happen.” His argument centers on two points: the products look more like swaps than futures, and the leverage levels, which can reach 50x or more, pose serious risks to retail traders.

The distinction between a future and a swap isn’t just semantic. It determines which regulatory regime applies, what kind of investor protections kick in, and who gets to offer the product. Traditional futures have expiration dates. Perpetual contracts don’t. They use a funding rate mechanism to keep prices tethered to the spot market. Duffy’s critique is that perpetuals structurally resemble swaps, which carry different regulatory requirements under the Commodity Exchange Act. If the CFTC were to reclassify them, it could upend Kalshi’s entire product line overnight.

The CFTC has classified Kalshi’s perps as futures contracts. That classification enables the agency to review additional contracts on a case-by-case basis, giving Kalshi a regulatory runway to expand while keeping the door open for future scrutiny.

What perpetuals actually are (and why they matter)

Perpetual futures contracts have been the backbone of crypto trading on offshore platforms for years. But until Kalshi’s launch, every single one of those contracts existed outside the US regulatory perimeter.

The 50x leverage that Duffy flagged is worth understanding in concrete terms. A trader putting up $1,000 with 50x leverage controls a $50,000 position. A 2% move against them wipes out their entire margin.

Kalshi’s expansion plans

Kalshi isn’t stopping at Bitcoin. On June 9, the platform listed a perpetual contract for Hyperliquid’s HYPE token, according to CFTC filings. The company has signaled plans to roll out perps for over a dozen additional tokens, including Ethereum, Solana, XRP, and Dogecoin.

Each new listing goes through the CFTC’s review process, which means the agency is effectively building a precedent library for how crypto perpetuals fit within the existing legal framework. Every approval reinforces the classification of these products as futures.

What this means for investors

US-based traders who previously had to navigate offshore exchanges now have a domestic option with actual investor protections. Clearing, margin requirements, and dispute resolution all fall under CFTC oversight.

CME Group has built a dominant position in regulated crypto futures, offering monthly and quarterly Bitcoin and Ethereum contracts to institutional clients. Kalshi’s perps target a different audience with a different product. Duffy’s public criticism isn’t just regulatory concern. It’s competitive positioning.
