BOX Wants Fancy Options Trading on Bitcoin Trusts and ETFs
Published Date: 12/5/2025
Notice
Summary
BOX Exchange wants to let traders use FLEX Equity Options on three popular Bitcoin funds: Grayscale Bitcoin Trust, Grayscale Bitcoin Mini Trust, and Bitwise Bitcoin ETF. This change means more flexible trading choices for investors interested in Bitcoin-related funds, starting once the SEC gives the green light. If approved, it could open new ways to manage risk and boost trading activity on these funds.
Analyzed Economic Effects
3 provisions identified: 2 benefits, 1 costs, 0 mixed.
FLEX Options Allowed on Three Bitcoin ETFs
BOX Exchange proposes to permit FLEX Equity Options on the Grayscale Bitcoin Trust (GBTC), the Grayscale Bitcoin Mini Trust (BTC), and the Bitwise Bitcoin ETF (BITB). The SEC waived the 30-day operative delay and designated the proposed rule change operative upon filing (filed November 17, 2025), meaning these exchange-traded FLEX options can be offered immediately upon the rule's filing.
FLEX and Non‑FLEX Positions Will Be Aggregated
The Exchange would require aggregation of any FLEX and non‑FLEX positions in the same underlying Fund when calculating position and exercise limits under Rules 3120 and 3140. For example, assuming a 250,000-contract position limit for BTC, the Exchange would restrict a participant from holding positions that could result in receipt of more than 250,000,000 shares if all BTC options were exercised.
Exchange Trading Lowers OTC Credit Risk and Boosts Transparency
The proposal would make FLEX Fund Options available on an exchange rather than only in the OTC market, which the Exchange says should reduce counterparty credit risk because contracts are issued and guaranteed by The Options Clearing Corporation (OCC). The Exchange also expects greater standardization, increased liquidity, and more transparent price discovery compared with OTC trading.
