BitMEX released the "Q2 2026 Derivatives Report" on July 10, providing an in-depth analysis of the three main structural drivers behind the differences in funding rates in the perpetual futures market. The report's key findings include that Hyperliquid Bitcoin perpetual contracts generate an average annualized funding rate premium of 7.17% compared to Binance from 2023 to 2026.
Three Major Structural Drivers: Collateral Type, Exchange User Structure, and Index Construction Method
According to the BitMEX Q2 2026 Derivatives Report, the three main structural factors influencing funding rate differences are:
Collateral Type Differences: Contracts backed by Bitcoin (e.g., XBTUSD) versus those backed by USDT (e.g., XBTUSDT) exhibit markedly different funding rate environments; over the past three and a half years, the average annualized difference is approximately 3.93%, with the rate remaining negative in 94% of rolling 90-day periods.
Exchange User Structure Differences: Hyperliquid Bitcoin perpetual contracts have an average annualized funding rate premium of 7.17% over Binance (ETH perpetuals at 5.31%). BitMEX attributes this mainly to differences in trader demographics and operational barriers limiting institutional arbitrage on decentralized platforms.
Index Construction Method Differences: The way tokenized commodity perpetual contracts build their indices impacts funding rate performance. During the WTI futures rollover in April 2026, the WTIUSDT funding rate briefly plummeted to an annualized -531%, unrelated to broader market sentiment.
XBTUSD and XBTUSDT Funding Rate Annualized Gap of 3.93%
Based on the BitMEX report, the funding rate difference between Bitcoin-backed XBTUSD and USDT-backed XBTUSDT contracts has averaged about 3.93% annually over the past three and a half years, remaining negative in 94% of rolling 90-day periods.
This gap stems from differing responses of the two collateral types under market stress: BTC-backed contracts' funding rates are influenced by Bitcoin's price volatility, while USDT-backed contracts experience a relatively stable funding environment. The structural differences are consistent over time rather than driven by short-term events.
Hyperliquid Bitcoin Perpetual Premium of 7.17% Over Binance
From 2023 to 2026, Hyperliquid's Bitcoin perpetual contracts have maintained an average annualized funding rate premium of 7.17% over Binance, with Ethereum perpetuals showing a 5.31% premium.
BitMEX attributes this divergence mainly to two factors: differences in trader demographics (user types and behaviors across platforms) and operational barriers restricting institutional investors from arbitraging across decentralized exchanges. These barriers prevent efficient convergence of funding rates, resulting in persistent premiums.
Frequently Asked Questions
What are the core findings of the Q2 2026 Derivatives Report?
According to the report, key findings include: an average annualized funding rate gap of 3.93% between XBTUSD and XBTUSDT (94% of the time negative); Hyperliquid Bitcoin perpetuals with a 7.17% premium over Binance; during the WTI futures rollover, the WTIUSDT funding rate briefly dropped to about -531% annualized; these gaps are mainly driven by structural factors rather than short-term sentiment.
What are the three main structural drivers behind funding rate differences?
The report identifies: collateral type (BTC vs. USDT), exchange user demographics and arbitrage barriers, and index construction methods (affecting tokenized commodity perpetual contracts' funding behavior).
Why did the WTIUSDT funding rate briefly reach -531%?
During the April 2026 WTI futures rollover, as the futures-based index transitioned between contracts, BitMEX's WTIUSDT funding rate temporarily plummeted to about -531% annualized. This illustrates how the index construction for assets like WTI influences funding rates independently of broader market sentiment.
