Bybit announced it will revert the mark price calculation method for applicable perpetual contracts to the standard method, moving away from the calculation introduced in November 2025. The transition will begin on Sep 2, 2026, and is expected to be completed by Sep 7, 2026. This change aims to ensure greater consistency across all perpetual contracts and better align with the market's general understanding of mark prices under various conditions. The update will be applied automatically, and existing positions, trades, and historical data will not be affected.
