SEC Unchains Bitcoin Options: Bigger Bets on Digital Dollars Allowed
Published Date: 8/1/2025
Notice
Summary
The SEC just gave the green light to NYSE Arca to change the rules for trading options on the Grayscale Bitcoin Trust (GBTC). Now, traders can hold bigger positions and use flexible options, making it easier and more flexible to trade GBTC options. These changes kick in soon and could shake up how investors play with Bitcoin-related options.
Analyzed Economic Effects
4 provisions identified: 2 benefits, 1 costs, 1 mixed.
Larger GBTC Options Position Limits
If you trade options on the Grayscale Bitcoin Trust (GBTC), the Exchange removed the prior 25,000-contract limit and will apply the position and exercise limits in Exchange Rule 6.8-O, Commentary .06(a)-(e). GBTC qualifies for the 250,000-contract limit under Commentary .06(e)(i) (which requires at least 100,000,000 shares traded in the most recent six months); the Exchange noted GBTC had 550,687,400 shares traded in the six-month period ending November 25, 2024.
On-Exchange FLEX GBTC Options Allowed
The Exchange will permit Flexible Exchange (FLEX) options on GBTC to trade on-exchange. FLEX GBTC options will be centrally cleared and guaranteed by the Options Clearing Corporation (OCC) and the Exchange said this is more transparent and presents less counterparty credit risk than the over-the-counter (OTC) market.
FLEX and Non‑FLEX Positions Are Aggregated
Positions in FLEX GBTC options will be aggregated with positions in non‑FLEX GBTC options when calculating position and exercise limits. For example, under a 250,000-contract limit the Exchange stated a 250,000-contract position would represent 25,000,000 shares of GBTC.
Large‑Position Reporting Requirement Continues
The Exchange will continue to require members to report their GBTC options positions and hedging information to the Exchange, and will continue the rule that members must file reports for any customer who held aggregate large long or short positions on the same side of the market of 200 or more option contracts for the previous day.
