Binance announced today that will update the settlement price rule for Commodity Options to match the methodology used for Crypto Options.

The new rule will apply to contracts expiring on Monday, November 23, 2026 17:00 (ET), and all Commodity Options expiring after that time. Contracts expiring before 17:00 (ET) on Monday, November 23, 2026 will continue to use the previous rule, even if their settlement is processed later.

The rule applied to each contract will be determined by its expiration time.

Under the previous rule, settlement was based on the underlying market close price at 17:00 (ET) on the expiration date. Under the new rule, the settlement price will be the arithmetic mean of the Binance Futures Index Price during the 0.5 hours preceding expiration.

Expiration times, trading sessions, and contract specifications will remain unchanged.

The calculation uses 1/1,800 multiplied by the sum of 1,800 price observations. For example, the XAU-261130-4000-C contract, which settles at 2026-11-30 17:00:00 (ET), will use the average XAU Futures Price Index from 2026-11-30 16:30:00 to 2026-11-30 17:00:00 (ET).
