New Alternative Path to Reduced Trading Fee
If you are a Member of MEMX that executes retail orders in stocks priced below $1.00, you can now qualify for the reduced Removed Sub-Dollar Retail Volume fee of 0.18% of the transaction dollar value either by (1) achieving a Retail Order ADAV of at least 20,000,000 shares, or (2) achieving a Retail Order ADAV of at least 10,000,000 shares and a Step‑Up Retail Order ADAV that is at least 50% of your April 2026 Retail Order ADAV. The Exchange’s standard fee for Removed Sub-Dollar Retail Volume remains 0.28% if you do not qualify for the tier.
Alternative Qualification Is Temporary
The new alternative qualification (10,000,000 Retail Order ADAV plus a Step‑Up Retail Order ADAV at least 50% of April 2026 Retail Order ADAV) will expire no later than January 31, 2027; the Exchange will note this expiration on the Fee Schedule and may terminate Criteria (2) earlier but would file with the SEC if it does so prior to January 31, 2027. That means the easier path to the 0.18% fee is temporary.

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."
