Altcoin Futures Open Interest Surpasses Bitcoin for First Time Since December 2024

The open interest in altcoin perpetual futures surpassed that of Bitcoin for the first time since December 2024, driven by a strong rally in Zcash. On September 6, 2026, Zcash futures saw their open interest rise to around $2.4 billion as the token surged past $1,000. This surge was partly due to the introduction of a new U.S. spot ETF and significant short liquidations.

This shift in market positioning indicates growing participation and leverage in altcoins, but does not necessarily signal a permanent change in market leadership. Bitcoin remains the largest single crypto derivatives market, and investors should continue to monitor funding rates, spot volumes, and open interest trends to gauge market stability and potential liquidation risks.
