Analyzed Economic Effects
4 provisions identified: 3 benefits, 1 costs, 0 mixed.
Trade Bitcoin Options Without Owning Bitcoin
Nasdaq PHLX proposes a new index option with ticker XBTX that would let you trade Bitcoin price exposure without buying Bitcoin. XBTX would be cash-settled, European-style, and based on the CME CF Bitcoin Real Time Index (BRTI) divided by 100, with final settlement using the BRRNY--NOS (BRRNY divided by 100).
Helps Spot Bitcoin ETP Holders Hedge Exposure
The proposed Nasdaq Bitcoin Index Options would allow holders of Spot Bitcoin exchange-traded products (ETPs) to hedge or change their Bitcoin exposure on a national securities exchange. The Exchange says investors could carry the options in the same account and subject to the same margin regime as the Spot Bitcoin ETP shares.
Final Settlement Uses BRRNY--NOS U.S. Close Method
The options' final settlement value would use the BRRNY--NOS, which is the BRRNY calculated from transactions between 15:00 and 16:00 New York Time on the expiration date, partitioned into twelve 5-minute intervals and averaged, then divided by 100. The Exchange says this creates a replicable, manipulation-resistant benchmark aligned with the U.S. market close.
Listing Depends on CFTC and OCC Approvals
Phlx acknowledges it cannot list or trade XBTX until the CFTC grants exemptive relief under Section 4(c)(1) of the Commodity Exchange Act and until the Options Clearing Corporation receives relief and updates the Options Disclosure Document. That means the product will not be available to trade until those regulatory approvals occur.

2026-17183, Regulation Crypto Assets
The Securities and Exchange Commission ("Commission") is proposing new rules to create a tailored offering regime for certain investment contracts involving crypto assets. The proposed offering regime is intended to facilitate capital formation and accommodate innovation within the crypto asset markets while, at the same time, ensuring that investors are adequately protected and provided with the information they need to make informed investment decisions. The proposed rules would be set forth in a new regulation titled "Regulation Crypto Assets" and would include two exemptions from the registration requirements of section 5 of the Securities Act of 1933. The first exemption would permit offerings of up to $5 million during a four-year period. The second exemption would permit offerings of up to $75 million during each 12-month period. Under both exemptions, issuers would be required to make certain principles-based narrative disclosures available to their investors. In addition, issuers under the second exemption would be required to provide financial statements and would be subject to ongoing reporting requirements. Issuers that rely on these exemptions would remain subject to the antifraud and antimanipulation provisions of the Federal securities laws. The proposed rules also would include a conditional safe harbor from the term "investment contract" in the definitions of "security" in the Securities Act of 1933 and the Securities Exchange Act of 1934. If the conditions of that proposed safe harbor are satisfied, then a crypto asset would be deemed not to be subject to an investment contract for purposes of those definitions of "security."
