Count Trades by Contra‑Party Weight
If you are an Entering Firm (an OTP Holder or OTP Firm), you may now tell the Exchange to count trades toward your Activity‑Based Risk limits using a contra‑party weighting of up to 200%. This applies to the Transaction, Volume, and Percentage activity limits; for example, you could choose to count only 50% of the quantity on each trade with a Customer toward your limits.
Market Makers Must Use Activity Controls
Market Makers are required to apply one Activity‑Based Risk Control to all of their orders and quotes on the Exchange. As Market Makers, they may now also specify contra‑party weights (up to 200%) when setting those controls.
Optional Feature Available to All Firms
The contra‑party weighting enhancement is optional and is available to all Entering Firms (including Market Makers) to use at their discretion. The Exchange states the enhancement applies uniformly to any Entering Firm that chooses to utilize it.
Rule Change Effective Immediately
The Exchange filed the change on May 19, 2026 and the proposed rule change became effective upon filing under the fast‑track rule (Rule 19b‑4(f)(6)). Entering Firms can begin using the new contra‑party weighting option immediately, though the SEC may summarily suspend the change within 60 days of the 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."
