Bybit Migrates to Single-Counted Open Interest Reporting

Bybit, a leading cryptocurrency exchange, has announced plans to switch to a single-counted method for reporting open interest on its derivatives markets. This change is expected to take effect on June 11, 2026, and will likely result in displayed OI figures appearing lower than before.

The current bilateral method, which counts matching long and short positions separately, will be replaced by a unilateral system that counts the same market activity only once. While this may lead to a 50 percent reduction in reported OI, traders' actual positions, margin requirements, profit and loss calculations, position limits, and risk exposure will remain unaffected.

The shift to single-counted reporting is designed to bring Bybit's methodology closer to global derivatives market standards, where open interest is generally counted once. This change is expected to improve comparability across exchanges and provide a more accurate representation of market activity.
