For years, perpetual futures have been a staple of the crypto trading landscape, particularly among investors outside the US. Now, with these contracts entering the regulated American market, Wall Street is grappling with the question of whether they represent a fleeting retail fad or a lasting challenge 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, making it the company's most successful product debut since prediction markets.

The exchange has since sought regulatory approval to offer 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 their positions. Instead, periodic funding payments help maintain the contract's price in line with the underlying asset.

This product has become a cornerstone of global crypto trading, with Bank of America estimating the annual perpetual futures volume to be around $90 trillion. On May 29, the Commodity Futures Trading Commission (CFTC) gave Kalshi the green light to offer these contracts, and Coinbase also received approval to list regulated perpetual futures in the US. However, within Wall Street, interest does not necessarily translate to immediate adoption.

While discussions about perps are becoming more frequent, partly due to US regulators allowing offshore markets to move onshore, most large financial institutions are still in the process of studying these 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, big 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 their positions in response to events and use weekend prices to estimate where CME futures may reopen, making perps useful for both hedging and price discovery.

However, the demand for these products must be sufficient to justify the commitment of capital, and the current lack of depth in the market, particularly during weekends, poses a significant challenge. Furthermore, a regulatory battle is emerging, with questions surrounding the classification of perpetual contracts as futures or swaps, which affects margin rules, registration duties, and liquidity provision. The debate is also taking on a competitive dimension, with CME challenging the CFTC's treatment of Kalshi's bitcoin perpetuals and similar disputes potentially arising as exchanges seek to expand perps into other asset classes.

For now, Wall Street's stance is one of caution rather than hostility, with trading firms recognizing a product they understand, regulators seeing a market moving onshore, and exchanges eyeing an opportunity to capture new volume. Nevertheless, the largest banks are unlikely to take the lead, instead waiting for the rules, liquidity, and infrastructure to mature.
