Analyzed Economic Effects
5 provisions identified: 3 benefits, 1 costs, 1 mixed.
Faster One‑Minute Data Helps Traders
The one-minute product provides the same Open-Close fields as the existing 10-minute intraday product but on one-minute intervals (first intraday calculation example ~9:34 a.m. ET for 9:30–9:31 a.m.). The Exchange says this more frequent data may help market participants identify new interest or fading interest during the trading day and be used to create and test trading models and strategies.
One‑Minute Report Purchasable by All
Cboe’s One-Minute Interval Intraday Open-Close Report is available for purchase by Cboe Trading Permit Holders (TPHs) and non-TPHs. The report captures data every 1 minute and the Exchange intends to make each one-minute snapshot available to subscribers within about five minutes (the Exchange expects delivery variability of 2–5 minutes).
Fees To Be Set in Separate Filing
The Exchange intends to submit a separate rule filing to establish fees for the One-Minute Interval Intraday Open-Close Report. The current filing does not set the fees; prospective subscribers should watch for the separate fee filing.
Product Is Voluntary to Buy
The Exchange describes the One-Minute Intraday Open-Close Data as a completely voluntary product: the Exchange is not required to make it available and potential customers may purchase it only if they voluntarily choose to do so.
Immediate Effect with 60‑Day SEC Review Risk
Cboe filed the proposed rule change on June 13, 2025 and the Exchange states the change became effective immediately under Section 19(b)(3)(A) and Rule 19b-4(f)(6). The SEC may, within 60 days of filing, temporarily suspend the change if it appears necessary or appropriate in the public interest.

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."
