BitMEX released its “Q2 2026 Derivatives Report” on July 10, 2026, providing an in-depth analysis of three major structural drivers behind differences in funding rates in the perpetual futures market. Key findings from the report include that Hyperliquid generated an average 7.17% annualized funding rate premium on bitcoin perpetual contracts versus Binance during the period from 2023 to 2026.
Three Major Structural Drivers: Collateral Type, Exchange User Composition, and Index Construction Method
According to BitMEX’s Q2 2026 derivatives report, the three major structural drivers of funding rate differentials are as follows:
Collateral Type Differences: Between contracts margined in bitcoin (e.g., XBTUSD) and contracts margined in USDT (e.g., XBTUSDT), the funding rate environment is fundamentally different. Over the past three and a half years, the average annualized gap was approximately 3.93%, and it remained negative in 94% of the rolling 90-day periods.
Exchange User Composition Differences: Compared with Binance, Hyperliquid bitcoin perpetual contracts generated an average 7.17% annualized funding rate premium (ETH perpetual was 5.31%). BitMEX attributes this mainly to differences in trader demographics, as well as operational barriers that limit institutions from performing arbitrage on decentralized platforms.
Index Construction Method Differences: The index construction of tokenized commodity perpetual contracts itself can affect funding rate performance. During the WTI futures roll in April 2026, the WTIUSDT funding rate briefly fell to an annualized level of approximately -531%, with no relation to broader market sentiment.
3.93% Annualized Funding Rate Gap Between XBTUSD and XBTUSDT
According to the BitMEX report, the funding rate differential between the XBTUSD contract, which is margined in bitcoin, and the XBTUSDT contract, which is margined in USDT, averaged approximately 3.93% annualized over the historical data from the past three and a half years. It also remained negative in 94% of the rolling 90-day periods.
This gap stems from the different reactions of the two collateral types under market stress: funding rate behavior for BTC-margined contracts is influenced by bitcoin’s own price volatility, while the funding rate environment for USDT-margined contracts is relatively stable. The structural differences between the two show consistency across the time span, rather than being driven by one-off short-term events.
7.17% Annualized Premium: Hyperliquid Bitcoin Perpetual vs. Binance
According to the BitMEX report, during the research period from 2023 to 2026, Hyperliquid’s bitcoin perpetual contracts generated an average 7.17% annualized funding rate premium versus Binance, while ether perpetual contracts showed a 5.31% premium.
BitMEX attributes the divergence mainly to two factors: differences in trader demographics (the two platforms have different user types and behavioral patterns), and operating barriers that restrict institutional investors from performing cross-exchange arbitrage activities on decentralized platforms. These barriers make it difficult to efficiently hedge away funding rate differentials, thereby creating a persistent funding rate premium.
FAQ
What are the key findings of BitMEX’s Q2 2026 derivatives report?
According to the BitMEX report, the key findings include: an average 3.93% annualized funding rate gap between XBTUSD and XBTUSDT (negative for 94% of the time); an average 7.17% annualized premium for Hyperliquid bitcoin perpetual versus Binance; WTIUSDT funding rates falling briefly to an annualized level of approximately -531% during WTI futures rolling; and these differentials are mainly driven by structural factors rather than short-term sentiment.
What are the three major structural drivers of funding rate differentials?
According to the BitMEX report, the three major drivers are: collateral type (BTC-margined vs USDT-margined), exchange user composition differences (different trader demographics and institutional arbitrage barriers), and index construction method (influencing the funding rate behavior of tokenized commodity perpetual contracts).
Why did the WTIUSDT funding rate briefly reach -531%?
According to the BitMEX report, during the WTI futures roll in April 2026, as the index based on futures was rolled between contracts, BitMEX’s WTIUSDT funding rate briefly fell to an annualized level of approximately -531%. This indicates how trading platforms construct indexes for new digital assets like WTI, which in itself affects funding rate performance, and this is unrelated to broader market sentiment.
