Binance Adjusts KORUUSDT Perpetual Contract Size

Binance Futures to Adjust KORUUSDT Contract Size Following Stock Dividend

Binance Futures is set to adjust the contract size for its USDⓈ-Margined KORUUSDT Perpetual Contract on July 15, 2026, commencing at 00:15 UTC. This adjustment is necessitated by forward share splits of the underlying asset issuer’s issued and outstanding shares, structured as a stock dividend. The adjustment process is anticipated to conclude by 13:30 UTC on the same day, with a subsequent “cancel-only” phase that could last up to five minutes.

Underlying Asset and Split Details

The underlying asset for the KORUUSDT Perpetual Contract is the Direxion Daily South Korea Bull 3X ETF (NYSE Arca: KORU). The issuer has announced a 20-for-1 forward share split, implemented as a stock dividend. This means the adjustment scale factor will be 20.

Impact on Open Positions and Trading

During the adjustment period, all strategy bots, including Grid, DCA, and Snowball, linked to the KORUUSDT perpetual contract will be terminated and their positions automatically closed at 00:05 UTC on July 15, 2026. These positions will not be reinstated after the adjustment.

Users with open positions will see their positions closed first, with unrealized profits and losses settled and credited to their Cross Margin Futures Account. For users in isolated margin mode, realized profits and all margin balances will be transferred to their Cross Margin Futures Account. Following the adjustment, new positions can be opened, with margin balances transferred to the Isolated Margin Futures Account based on the leverage level selected prior to the adjustment.

The “cancel-only” phase will permit users to submit, modify, or cancel Post-Only orders. The duration of this phase will be determined by Binance, depending on market liquidity, and may extend up to five minutes.

Chart and Data Continuity

The continuous candlestick chart for the KORUUSDT perpetual contract will be retained and updated with the newly adjusted price. For time intervals of 12 hours and below, price charts prior to 00:00 UTC on July 15, 2026, will be corrected within the first week post-adjustment.
