The U.S. Securities and Exchange Commission (SEC) has approved Nasdaq's proposal to launch cash-settled Bitcoin index options on the Philadelphia Stock Exchange. These options, trading under the ticker QBTC, offer exposure to Bitcoin price movements without direct ownership or physical delivery. However, trading cannot commence until the Commodity Futures Trading Commission (CFTC) grants exemptive relief, as Bitcoin is treated as a commodity under CFTC oversight. The approved European-style contracts are linked to the Nasdaq Bitcoin Index, which updates every 200 milliseconds using data from major cryptocurrency exchanges. The SEC's decision reflects a shift in crypto policy under Chairman Paul Atkins, who advocates for clearer digital asset regulations. The SEC also set a position limit of 24,000 contracts per side, equating to about 0.12% of Bitcoin's supply. This development marks a significant step in regulated Bitcoin trading, pending CFTC's final approval.
