Kalshi's Perps Cross $1B in a Week, Draw CME Chief's Warning

Kalshi just did something no one else has pulled off on U.S. soil: launch regulated cryptocurrency perpetual futures contracts. The CFTC-supervised prediction market debuted its BTCPERP contract on May 29, and the response was immediate. Over $100 million in notional volume traded in the first 24 hours. Within a week, that figure crossed $1 billion.

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 rests on two points. The products look more like swaps than futures, Duffy said. And the leverage levels, which can reach 50x or more, pose serious risks to retail traders.

The difference between a future and a swap is not semantic. It determines which regulatory regime applies, what investor protections kick in, and who can offer the product. Traditional futures have expiration dates. Perpetual contracts do not. They use a funding rate mechanism to stay tethered to the spot market. Duffy’s critique is that perpetuals structurally resemble swaps, which carry different requirements under the Commodity Exchange Act. If the CFTC reclassifies them, it could upend Kalshi’s product line.

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

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

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

Kalshi is not stopping at Bitcoin. On June 9, the platform listed a perpetual 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, meaning the agency is building a precedent library for how crypto perpetuals fit within the existing legal framework. Every approval reinforces the classification of these products as futures.

U.S. 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 is not just regulatory concern. It is competitive positioning.

CME Group holds an Alpha Score of 50 out of 100, labeled Mixed, in the Financials sector. For more on the company, visit the CME stock page.

One open question is whether the CFTC’s case-by-case approval model scales. If Kalshi lists 15 tokens and the agency reviews each one individually, the process could become a bottleneck. The agency declined to comment on its review timeline.
