Larger Options Limits for Three Bitcoin ETFs
BOX removed the 25,000-contract position and exercise limit that applied to options on the Grayscale Bitcoin Mini Trust (BTC), the Bitwise Bitcoin ETF (BITB), and the Grayscale Bitcoin Trust (GBTC), permitting those ETFs to qualify for higher aggregated limits. The filing references analyses supporting an aggregated limit of 250,000 same-side contracts (compared to the prior 25,000-contract limit).
Change Effective Immediately
The Exchange filed the proposed rule change on August 15, 2025, and the Commission waived the 30-day operative delay and designated the proposal as operative upon filing, making the amendment effective immediately. The Federal Register notice was published August 25, 2025.
Position Reporting Rules Stay The Same
BOX will keep its existing position and large-position reporting requirements: Participants must continue to report options positions and hedge descriptions, Market Makers remain exempt from the reporting requirement (though the Exchange may access Market Maker position information), and the customer large-position reporting trigger remains at 200 option contracts for the prior day.
