Perpetual futures, or “perps,” are the largest market crypto has built, and they are quietly reversing the story everyone tells about convergence. Crypto is described as maturing toward traditional finance, adopting its discipline around revenue, buybacks and disclosure. In perps, the movement runs the other way: traditional assets are migrating onto a structure that crypto invented.
The scale is easy to underestimate. Perps are the deepest and most liquid instrument in crypto, with daily volumes that have approached three-quarters of a trillion dollars and that routinely run several times the size of the spot markets they reference. Their design stripped out the two features that define a traditional future, the expiry and the settlement date, and replaced them with a funding rate that keeps the contract anchored to spot. For most of their history, they were treated as a crypto-native product with little relevance beyond it.
