Over the years, Crypto might have contributed more to traditional finance than just Bitcoin and Tokenization. Now, even trading methods are starting to make their way out. Kalshi is preparing to apply to U.S. regulators to launch WTI crude oil perpetual contracts. If approved, these Perps—already highly mature in the Crypto market and without fixed expiration dates—will further enter the traditional commodities market. Based on the information disclosed so far, Kalshi is aiming for 24/5 trading. What’s worth paying attention to here is that Perps are one of the most representative products in the Crypto derivatives market. Traditional futures have expiration dates, requiring rollovers and position transfers. Perps, on the other hand, have no fixed expiration date and use mechanisms like funding rates to keep prices aligned with spot markets, enabling more continuous trading. In the past, when people talked about Crypto changing finance, they often thought about creating new assets or bringing traditional assets like stocks and bonds onto the blockchain. But now, there’s another path emerging: Assets don’t necessarily need to be on-chain; the trading mechanisms developed in Crypto can also be adopted by traditional markets. These two approaches are fundamentally different. One changes “what to trade,” while the other changes “how to trade.” If Perps gradually start appearing in oil, metals, stock indices, and even more traditional markets in the future, then what Crypto leaves behind for the financial market might not just be a few new assets. It could also include a set of trading rules that Crypto users are already accustomed to today.
