Cboe BZX Exchange amended five proposed spot Bitcoin exchange-traded-product filings on July 11, 2023, specifying its planned surveillance-sharing relationship with Coinbase. The coordinated revisions mattered because they addressed a recurring obstacle in the Securities and Exchange Commission’s rejection of earlier spot Bitcoin products: whether a listing exchange could obtain information useful for detecting fraud and manipulation in the underlying market.
Cboe’s official rule-filing register records July 11 amendments for the ARK 21Shares Bitcoin ETF, Invesco Galaxy Bitcoin ETF, VanEck Bitcoin Trust, WisdomTree Bitcoin Trust and Wise Origin Bitcoin Trust, the Fidelity-sponsored proposal. ARK’s submission was Amendment No. 3; the other four were Amendment No. 1.
These were proposed exchange rule changes, not approvals. None of the five products received permission to trade on July 11.
What the surveillance language established
The revised record said Cboe had reached an agreement on terms with Coinbase on June 21, 2023, and had executed an associated term sheet. It also said the parties expected to finalize and execute a definitive agreement before trading in the proposed trust shares could begin.
That distinction was material. Cboe and Coinbase had agreed on terms, but the filing did not represent that the definitive surveillance-sharing agreement was already fully executed on July 11.
Under the contemplated arrangement, Cboe expected to receive Coinbase market data for spot Bitcoin orders and trades when the exchange determined that information was necessary for its surveillance program. Cboe also expected to be able to request additional information concerning Coinbase trading activity when investigating possible manipulation in the proposed ETF shares.
The mechanism was intended to connect surveillance of the exchange-listed securities with activity in the spot market influencing their value. It did not guarantee that manipulation would be detected, establish Coinbase as a federally regulated securities exchange or resolve whether the SEC would consider the arrangement legally sufficient.
Why the amendments mattered
The SEC had repeatedly focused on surveillance-sharing when rejecting proposed spot Bitcoin products. In its March 10, 2023 VanEck decision, the Commission again concluded that the listing exchange had not established a comprehensive surveillance-sharing agreement with a regulated market of significant size related to spot Bitcoin.
Cboe’s July 11 revisions were therefore a targeted response to an identifiable regulatory objection rather than a cosmetic change. Five sponsors were advancing through separate products, but their planned listing exchange was now presenting Coinbase as a common surveillance node.
That role exposed a striking institutional tension. The SEC had sued Coinbase on June 6, 2023, alleging that the company operated an unregistered securities exchange, broker and clearing agency. Coinbase disputed the agency’s claims. Five weeks later, Cboe was proposing to rely on Coinbase trading information to strengthen applications intended to satisfy the SEC’s market-integrity requirements.
The coexistence of those two records did not resolve Coinbase’s legal status or invalidate the surveillance proposal. It showed how deeply the company had become embedded in the developing bridge between cryptocurrency markets and regulated investment products.
The immediate market signal
Reuters reported that Coinbase’s Nasdaq-listed shares closed the July 11 regular session at $89.15, up 9.8%. That is an equity-market close for COIN, not a Bitcoin price or a direct measurement of demand for the proposed funds. The timing supports interpreting the filings as favorable news for Coinbase’s institutional role, but it cannot prove that the amendments alone caused the entire move.
The defensible conclusion on July 11 remained narrow: Cboe had materially strengthened five spot Bitcoin product proposals by naming the market-surveillance counterparty and documenting agreed terms. SEC approval, execution of the definitive agreement and actual product launches all remained unresolved.
