For years, perpetual futures have been a staple in the crypto trading world, particularly among investors outside the US. Now, with their entry into regulated American markets, Wall Street is grappling with whether they are a fleeting retail trend or a lasting threat to traditional futures. The initial numbers are undeniable, 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 the product's potential to transcend 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 keep the contract's price aligned with the underlying asset. As a result, perps have become an integral part of global crypto trading, with Bank of America estimating their annual volume to be around $90 trillion. The Commodity Futures Trading Commission (CFTC) has cleared Kalshi and Coinbase to offer these contracts, marking a significant milestone.

However, within Wall Street, interest in perps does not necessarily translate to immediate adoption. Discussions about perps are becoming more frequent, partly due to US regulators allowing offshore markets to move onshore.

Nonetheless, most large financial institutions are still in the process of studying these products rather than preparing for major launches. Proprietary trading firms, market makers, and newer clearing firms are more likely to be the first movers, as they have the freedom to test new venues and accept operational risks without the stringent capital rules and client obligations that big banks face. 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. Despite the demand, firms are hesitant to commit balance sheet capital until customer activity justifies it.

The main challenge lies in depth, as a contract may trade continuously but institutions may struggle to move large positions without impacting the market. Weekend liquidity remains a concern, and collateral systems do not always move in tandem with the markets they support.

A regulatory battle is also emerging, with questions surrounding the treatment of perpetual contracts as either 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. For now, Wall Street's stance is cautious, with trading firms recognizing a product they understand, regulators seeing a market moving onshore, and exchanges eyeing an opportunity to capture new volume.

However, the largest banks are unlikely to take the lead, instead waiting for the rules, liquidity, and infrastructure to mature.
