The U.S. Securities and Exchange Commission has approved a Cboe Options Exchange rule amendment allowing listed options on the WisdomTree Bitcoin Fund, adding another regulated derivatives layer to the spot Bitcoin ETF market. The approval applies specifically to options tied to BTCW, not to the underlying spot Bitcoin ETF itself, and it does not represent a new spot ETF approval.
The regulatory green light gives institutional traders more tools to hedge downside risk, sell covered calls, express volatility views and manage exposure within portfolio frameworks. Actual options trading will depend on exchange and clearing readiness, so the launch is not immediate. The SEC approval nevertheless signals that the regulated product stack around Bitcoin is still expanding and could help deepen market liquidity by attracting market makers and options traders.
On the same day, U.S. spot Bitcoin ETFs recorded $731 million in net inflows on September 3, led by BlackRock’s iShares Bitcoin Trust (IBIT) with $454 million. U.S. spot Ethereum ETFs also attracted $141 million in fresh capital, with BlackRock’s iShares Ethereum Trust (ETHA) contributing about $72.07 million. Combined, Bitcoin and Ethereum spot ETFs pulled in around $872 million in a single day.
Continued institutional demand across both Bitcoin and Ethereum investment products may reinforce the expanding role of regulated crypto vehicles, although options flows and dealer hedging can also add complexity to short-term market dynamics.
