How Perpetual Futures Dominate Bitcoin and Ether Markets, and What SpaceX Taught Us

The process of setting cryptocurrency prices is often misunderstood, with many believing it involves spot trading, where buyers and sellers meet on an exchange. However, the reality is that perpetual futures contracts, also known as perpetual swaps or 'perps', have become the dominant force in the crypto markets, accounting for around 93% of all crypto futures volume. These contracts are leverage-friendly, never expire, and can be held indefinitely by paying a funding rate. Research has shown that perpetual swaps on unregulated venues are the strongest instruments for bitcoin price discovery, with regulated futures and US spot exchanges reacting to these moves. The evidence suggests that the derivatives market is where the price is made, with spot markets following. A study in the Journal of Financial Markets found that perpetual swaps were the primary source of price formation, while other work has identified Binance's perpetual market as the main driver of price formation across the fragmented crypto landscape. Historically, perps have led the way during bear market price rallies, with Bitcoin perps demand growth leading the price rallies in January and April-May 2026. The funding rate, which is paid by the crowded side of the trade every few hours, acts as a tether that keeps the contract anchored and provides a live readout of sentiment. Traders watch the funding rate closely, as it provides valuable insights into market trends. The recent SpaceX IPO provided a unique example of the power of perpetual futures contracts in predicting market trends. Traders on Binance, Coinbase, and other platforms were able to buy and sell exposure to SpaceX through pre-IPO perpetual futures, which accurately predicted the company's valuation. The perpetual market was pricing SpaceX well above the IPO price, allowing traders to profit from the gap between the perp and the eventual opening price. The success of the perpetual market in predicting the SpaceX IPO price highlights the importance of derivatives in the crypto markets and demonstrates how they can be used to accurately predict market trends.
