Binance Adjusts ANTHROPICUSDT Futures Contract Size, Renames Ticker

Binance Futures to Adjust Contract Size and Rename ANTHROPICUSDT Pre-IPO Perpetual Contract

Binance Futures will adjust the contract size of its USDⓈ-Margined ANTHROPICUSDT Pre-IPO Perpetual contract and rename the ticker to USDⓈ-Margined ANTUSDT Pre-IPO Perpetual, effective November 17, 2026, at 08:30 (UTC). The adjustment process is expected to conclude by 11:00 (UTC) on the same day, a period designated as the “Adjustment Period.” A subsequent “cancel-only” phase may follow, lasting up to five minutes after the adjustment is finalized.

Contract Details and Share Count

The ticker will transition from ANTHROPICUSDT to ANTUSDT.

An initial estimated share count of 1 billion shares was published on June 2, 2026. This estimate has been revised to 13,116,075,288 shares, based on disclosures in the S-1/A-2 filing available on the SEC website. The actual share count could differ if the issuer updates its filing prior to the official IPO listing.

Binance has stated that if the difference between the share count used for the current contract size and the revised estimated share count on November 17, 2026, is less than 3%, no contract size adjustment will be made. However, Binance reserves the right to adjust the contract size should a new proposed share count become available, with a separate announcement to follow any such adjustment.

The adjustment will be implemented with a scale factor of 13.116.

Impact on Trading and Positions

Please note that all strategy bots, including Grid, DCA, and Snowball, configured on the ANTHROPICUSDT perpetual contract will be terminated at 08:15 (UTC) on November 17, 2026. All associated positions will be automatically closed, irrespective of the “Close all positions on stop” setting. These strategy bot positions will not be reinstated after the adjustment.

During the Adjustment Period, users with open positions on the affected perpetual contract will have their positions closed. Unrealized Profit and Loss (PNL) will be settled and credited to users’ Cross Margin Futures Accounts, regardless of their position mode settings. For users operating in isolated mode, their realized PNL and entire margin balance from their Isolated Margin Futures Account will be transferred back to their Cross Margin Futures Account. Following the adjustment, new positions can be established. The margin balance transferred back to the Isolated Margin Futures Account by the system will be based on the initial margin requirement of the leverage level selected by users prior to the adjustment.

The cancel-only phase will permit users to submit, modify, or cancel Post-Only orders exclusively. The duration of this phase will be determined by Binance based on prevailing market liquidity, potentially extending up to five minutes.

The continuous Kline (candlestick) chart for the last price of the perpetual contract will be corrected within 24 hours of the adjustment’s completion.
