From 10‑Minute to One‑Minute Updates
The new report delivers Intraday Open‑Close Data at one‑minute intervals instead of the existing ten‑minute intervals; snapshots are taken every 1 minute and would be available to subscribers within about five minutes (the Exchange expects delivery to range from 2–5 minutes after each one‑minute interval). For example, subscribers would receive the first one‑minute calculation at approximately 9:34 a.m. ET (data from 9:30–9:31 a.m.).
New One‑Minute Data Product Available
Cboe BZX has introduced a One‑Minute Interval Intraday Open‑Close Report that is available for purchase to both BZX Members and non‑Members starting with the filing on June 13, 2025. The product is voluntary and proprietary to the Exchange; potential customers may purchase it only if they voluntarily choose to do so.
Product Contains BZX‑Only Proprietary Data
The One‑Minute Intraday Open‑Close Data is proprietary Exchange trade data that does not include trade data from any other exchange. It provides volume summaries on BZX by origin, side, transaction type, and trade‑size buckets.
Fees Not Yet Established; Separate Filing Promised
The Exchange states it intends to submit a separate rule filing to establish fees for the One‑Minute Interval Intraday Open‑Close Report; no fee schedule is announced in this filing. The product is available for purchase but specific pricing will be set in a later filing.

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."
