Analyzed Economic Effects
5 provisions identified: 3 benefits, 1 costs, 1 mixed.
New “All Cancels” market report
Cboe BYX is adding a new optional report called the All Cancels Report that provides comprehensive cancel-related message data for the subscribing firm. The Exchange filed the rule change on August 5, 2025, the Commission made it operative upon filing, and the Exchange proposed to introduce the report on August 25, 2025 (date may change).
Subscription fees will be charged later
The All Cancels Report is optional but the Exchange says corresponding fees will be assessed based on the number of reports a subscriber selects. The Exchange plans to file a separate rule change to propose the specific fees (no specific fee amounts are in this filing).
Report contains only your firm’s data
The All Cancels Report will include only the subscribing (Recipient Firm)'s cancel-related message data and the Exchange will restrict other market participants from receiving another firm's data. The report will also not include any trade records or aggressor information.
Report is historical (T+1), not real-time
The All Cancels Report will not include real-time market data; it will contain historical data from the prior trading day and generally be available on a T+1 basis (after the end of the trading day).
Sponsored participants can subscribe directly
The Exchange clarified that Sponsored Participants may directly subscribe to the Cboe Timestamping Service reports (including the All Cancels Report) and be charged corresponding fees directly, in contrast to prior practice where a Member might subscribe and pass data along.

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."
