Example Suppose before the rebase you hold 1,000 long ABCUSDT pre-market perpetual contracts, with an average entry price of 80 USDT, a pre-rebase mark price of 110 USDT, and a contract face value of 1 ABC. At that moment: Unrealized PnL = (110 − 80) × 1,000 = 30,000 USDT Realized PnL = 04.1 After the Rebase (rebase_ratio = 1.1) The S-1 discloses an actual share count 1.1x OKX's estimate, so rebase_ratio = 1.1.
