The popularity of perpetual futures in the crypto space has been evident for years, particularly among investors outside the US. With the introduction of these contracts into regulated American markets, Wall Street is now grappling with the question of whether they represent a fleeting retail trend or a lasting challenge to traditional futures. The initial numbers have been impressive, with Kalshi's perpetual futures reaching $1 billion in trading volume within a week of launch in June.

This has prompted the exchange to seek regulatory approval for perpetual futures tied to gold and silver, indicating that the product may not be limited to bitcoin and other digital assets. Perpetual futures, also known as perps, are similar to standard futures contracts but lack an expiration date, eliminating the need for traders to close or roll over positions. Instead, periodic funding payments help maintain the contract's price in line with the underlying asset.

This product has become a staple of global crypto trading, with Bank of America estimating the annual volume of perpetual futures to be around $90 trillion. The Commodity Futures Trading Commission (CFTC) has cleared Kalshi and Coinbase to offer regulated perpetual futures in the US.

However, within Wall Street, interest in perps does not necessarily translate to immediate adoption. People familiar with the discussions indicate that while perps are being mentioned more frequently, most large financial institutions are still in the process of studying the products rather than preparing for major launches. The first movers are likely to be proprietary trading firms, market makers, and newer clearing firms, which have more freedom to test new venues and accept operational risks.

In contrast, large banks face stricter capital rules, client obligations, and reputational risks, making them more cautious in their approach. The potential applications of perps extend beyond speculation, as they could help traders manage weekend risk by providing a liquid 24-hour market. This could enable firms to adjust positions in response to events and use weekend prices to estimate where traditional futures may reopen.

Insiders argue that the demand for perps must be present for firms to commit capital, but the problem lies in depth, with contracts trading around the clock but lacking the liquidity to support large positions without shifting the market. A regulatory battle is also emerging, with questions surrounding the treatment of perpetual contracts as futures or swaps, which affects margin rules and registration duties. The debate is becoming increasingly competitive, with CME challenging the CFTC's treatment of Kalshi's bitcoin perpetuals and similar disputes potentially arising as exchanges expand perps into traditional markets.

For now, Wall Street's stance is cautious rather than hostile, with trading firms, regulators, and exchanges seeing opportunities in the product, but the largest banks are unlikely to take the lead until the rules, liquidity, and infrastructure are more established.
