For years, perpetual futures have been a staple in the crypto trading world, particularly among international investors. Now, with their introduction to regulated US markets, Wall Street is weighing whether they are a fleeting trend or a lasting threat to traditional futures. The initial numbers are impressive, with Kalshi's perpetual futures reaching $1 billion in trading volume within a week of launch in June.

This milestone marks the company's largest product debut since prediction markets, prompting the exchange to seek regulatory approval for perpetual futures tied to gold and silver. Perpetual futures, or 'perps,' are similar to standard futures contracts but lack an expiration date.

Traders are not required to close or roll over their positions monthly or quarterly, as periodic funding payments keep the contract's price aligned with the underlying asset. This product has become a cornerstone of global crypto trading, with Bank of America estimating annual perpetual futures volume at approximately $90 trillion.

Following the Commodity Futures Trading Commission's (CFTC) approval of Kalshi and Coinbase to offer regulated perpetual futures in the US, interest in the product is growing within Wall Street. However, this interest does not necessarily translate to immediate adoption.

Proprietary trading firms, market makers, and newer clearing firms are more likely to be the first movers, as they 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 perpetual futures extend beyond speculation, as they could help traders manage weekend risk. Traditional futures markets close over the weekend, leaving traders vulnerable to unexpected events.

A liquid 24-hour perpetual market could provide a solution, enabling firms to adjust their positions in real-time and use weekend prices to estimate where CME futures may reopen. Insiders argue that firms won't commit capital until customer demand justifies it, emphasizing the need for depth in the market.

The regulatory environment is also evolving, with debates surrounding the classification of perpetual contracts as futures or swaps. This distinction affects margin rules, registration duties, and who can provide liquidity. As exchanges push to expand perpetuals into commodities, equities, and other traditional markets, these legal questions will become increasingly important.

The competitive landscape is also shifting, with incumbent exchanges like CME challenging the CFTC's treatment of Kalshi's bitcoin perpetuals. For now, Wall Street's view on perpetual futures is cautious rather than hostile, with trading firms, regulators, and exchanges all seeing opportunities in the emerging market.

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