Analyzed Economic Effects
5 provisions identified: 4 benefits, 1 costs, 0 mixed.
FLEX Options Allowed on IBIT
You will be able to trade FLEX Equity Options on the iShares Bitcoin Trust (IBIT) on BOX Exchange because BOX filed to permit FLEX trading on IBIT (filed November 17, 2025). The Commission waived the 30-day operative delay on December 2, 2025 and designated the change operative upon filing.
FLEX and Non-FLEX Positions Aggregated
BOX will aggregate any FLEX and non-FLEX positions in IBIT when calculating position and exercise limits. For example, under a 250,000-contract position limit assumption, BOX would restrict a participant from holding positions that could result in the receipt of more than 250,000,000 shares if those options were exercised.
Exchange Trading Reduces Counterparty Risk
FLEX IBIT options traded on BOX would be issued and guaranteed by The Options Clearing Corporation (OCC), which reduces counterparty credit risk compared with over-the-counter (OTC) FLEX contracts. The Exchange cites OCC guarantee and exchange-trading as improving transparency and price discovery.
May Move OTC Liquidity to Exchange
BOX expects that FLEX IBIT options will attract market participants who currently trade similar customized FLEX options in the OTC market (e.g., hedge funds, proprietary trading firms, pension funds) and that this migration could increase liquidity and price discovery on the exchange. The filing also states offering FLEX IBIT options may open the market to more retail investors.
Immediate Operative Upon Filing
The Commission waived the 30-day operative delay and designated the proposed rule change to be operative upon filing, which was filed November 17, 2025 (waiver granted December 2, 2025). This means BOX may offer FLEX trading on IBIT without waiting the normal 30-day delay.

2026-19260, Rescission of Rule 14a-8's Federal Regulation of Shareholder Proposals and Amendments to Rule 14a-4
The SEC wants to stop its federal rule that controls how shareholders can make proposals at company meetings, letting state laws and company rules take over instead. They’re also changing rules so companies can sometimes vote on proposals not in their official materials—but shareholders can opt out if they want. This affects investors and companies, with comments open until November 20, 2026, and could shake up how shareholder voices are heard and counted.
2026-18424, Political Contributions by Certain Investment Advisers
The Securities and Exchange Commission (the "Commission" or the "SEC") is proposing to rescind the political contribution rule under the Investment Advisers Act of 1940 (the "Advisers Act"), which prohibits investment advisers from providing investment advisory services for compensation to a government client for two years after an adviser or any covered associate of the adviser makes a contribution to certain categories of elected officials or candidates, among other prohibitions. In the more than fifteen years since the rule was adopted, implementation challenges associated with the political contribution rule have resulted in a range of significant unintended consequences, including compliance practices among some investment advisers that may have had the effect of restricting all political contributions by the investment advisers and their employees. Market participants also have stated that the political contribution rule is burdensome, complex, and both lacks clarity and creates a de facto strict liability standard. The Commission is of the view that other existing requirements of the Advisers Act and its associated rules, including prohibitions on fraud, fiduciary duty requirements, the compliance rule, and the code of ethics rule (defined below), are likely sufficient to address pay-to-play practices while allowing an adviser the flexibility to implement an approach that is more appropriately tailored to its particular risks, rendering the political contribution rule unnecessary. The Commission also is proposing to amend the rule under the Advisers Act pertaining to books and records consistent with the proposed rescission.
2026-18190, Transfer Agent Rules
The U.S. Securities and Exchange Commission ("SEC" or "Commission") is proposing to adopt new rules, amend existing rules, amend the existing form for registration with the Commission as a transfer agent (Form TA-1) and the existing form for reporting activities of transfer agents (Form TA-2), and rescind an existing rule governing registered transfer agents. The proposals are designed to modernize the rules governing registered transfer agents.
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."
2026-12163, The Trade-Through Rule and Locked and Crossed Markets Provisions of Regulation NMS
The SEC wants to scrap some old rules that stop stocks from being traded at worse prices and prevent confusing market quotes. This change affects stock traders and exchanges, aiming to simplify trading and possibly speed things up. If you want to share your thoughts, you’ve got until August 17, 2026, so don’t miss out!
2026-10373, Registered Offering Reform
The SEC wants to make it easier and cheaper for more companies to sell their stocks and bonds to the public. They’re opening up special forms and benefits to more businesses, updating rules to be more modern, and cutting red tape by overriding some state rules. If you’re a company planning to raise money, these changes could speed things up and save you money, with feedback due by July 27, 2026.
