April, 2026 
SEC announced proposed amendments for optional semiannual reporting. The Securities and Exchange Commission (SEC) announcement about the proposal and amendment explained that it would give public companies the option of filing semiannual reports in lieu of quarterly reports to meet their interim reporting obligations under the federal securities laws. Under the proposal, the filing deadline for semiannual reports on Form 10-S would be 40 or 45 days, depending on the company's filer status, after the end of the first semiannual period of the fiscal year. The proposal also would amend Regulation S-X, which governs the financial statement requirements for periodic reports, registration statements, and proxy statements, to reflect the new semiannual reporting option and simplify the existing financial statement requirements. The Commission prepared a fact sheet concerning the proposal which is out for a 60-day public comment period ending July 6, 2026.
XBRL US responded to Notice of Proposed Rulemaking related to the GENIUS Act for 3 separate federal agencies: OCC, FDIC, NCUA. The proposal from the Office of the Comptroller of the Currency (OCC), Implementing the Guiding and Establishing National Innovation for U.S. Stablecoins Act for the Issuance of Stablecoins by Entities Subject to the Jurisdiction of the Office of the Comptroller of the Currency contains guidance on the issuance of payment stablecoins and related activities by entities that are subject to OCC regulation. The XBRL US letter explained the importance of enhancing this rule and future rules by requiring the application and ongoing disclosures by digital asset issuers to be prepared in structured, digital format using widely used, technology-neutral open data standards such as XBRL.
Separately, XBRL US submitted a comment letter in response to the Federal Deposit Insurance Corporation (FDIC) Notice of Proposed Rulemaking: Approval Requirements for Issuance of Payment Stablecoins by Subsidiaries of FDIC-Supervised Insured Depository Institutions published by the FDIC. The FDIC has jurisdiction for applications for issuance of payment stablecoins and related payment stablecoin activities by subsidiaries of FDIC-supervised institutions for which the FDIC is the primary Federal payment stablecoin regulator.
Last, XBRL US sent a letter to the National Credit Union Administration (NCUA) to address the Notice of Proposed Rulemaking: Investments in and Licensing of Permitted Payment Stablecoins Issuers, RIN 3133–AF69. The NCUA has jurisdiction over payment stablecoin issuers that are subsidiaries of federally insured credit unions (FICU).
XBRL US commented on the California Air Resources Board (CARB) Notice of Public Hearing and Proposed Amendment to the Regulation for the Mandatory Reporting of Greenhouse Gas Emissions (MRR). The MRR program, which has been effective since 2009, requires electricity generators, industrial facilities, fuel suppliers, and electricity importers that emit more than 10,000 metric tons of CO2e (approximately 800 covered entities) to submit annual reports. Emissions data can be downloaded from the CARB website in Excel spreadsheets.
In December, the New York State Department of Environmental Conservation announced their own Mandatory Greenhouse Gas Reporting program which also requires certain GHG emissions sources that emit over 10,000 metric tons of CO2e to report emissions to the department. Read the fact sheet. Data for the 2026 emission year will be due starting June 1, 2027.
The XBRL US letter explained that if California, New York, and other states like Washington were to collect this data in structured, standardized format, the information would be less expensive to process, more accessible, comparable, and interoperable. We made this argument in a white paper published in December.
The theme of the paper was further supported by the Data Foundation podcast and related blog, The Case for Standardizing the Way We Report Climate and Environmental Data. The podcast, released on April 20, 2026, featured Liv Watson who is also co-Founder of the Digital Global Single Market Data Alliance and Catherine Atkin, a co-chair of the Law x Climate project at Stanford Codex who is also a co-founder of the Digital Global Single Market Data Alliance. Both Liv and Catherine are Senior Fellows with the Data Foundation's Climate Data Collaborative.
SEC requested comment on central matching service provider's securities trade report. The Securities and Exchange Commission (SEC) published a Comment Request on extending Rule 17 Ad-27, which requires exempt entities that perform matching services to facilitate the settlement of securities transactions (referred to as a "central matching service provider" or "CMSP") to establish, implement, maintain and enforce policies and procedures reasonably designed to facilitate straight-through processing for transactions involving broker-dealers and their customers. CMSPs electronically facilitate communication among a broker-dealer, an institutional investor or its investment adviser, and the institutional investor's custodian to reach agreement on the details of a securities trade. CMSP data must be reported in Inline XBRL format. Comments must be submitted by June 22, 2026.
FDIC solicited comments on requirements related to the GENIUS Act. The Federal Deposit Insurance Corporation (FDIC) proposal addresses certain requirements related to the GENIUS Act that apply to permitted payment stablecoin issues that are under FDIC supervision. The proposal is out for a public review period that closes on June 9, 2026. This is the second FDIC proposal related to the GENIUS Act. The first proposal covered approval requirements for issuance of payment stablecoins by subsidiaries of FDIC-supervised insured depository institutions. XBRL US commented on that proposal on April 8, 2026.
Treasury seeks comment on GENIUS Act state-level regulation. The U.S. Department of Treasury announced that they were seeking comment on their GENIUS Act Notice of Proposed Rulemaking Concerning State-Level Regulatory Regimes. This NOPR applies to payment stablecoin issuers with a consolidated total outstanding issuance of no more than $10,000,000,000. These issuers can opt for state-level regulation, as long as the state regulation is substantially similar to the federal regulatory framework. The rule proposal establishes principals for making that determination and comments are due by June 2, 2026.

XBRL US weighed in on the SEC proposal to reform Regulation S-K. On January 13, 2026, SEC Chair Atkins issued a Statement on Reforming Regulation S-K, noting, "Today, the disclosure that companies provide in response to the myriad requirements of Regulation S-K does not always reflect information that a reasonable investor would consider important in making an investment or voting decision… The Commission's disclosure regime should enable a reasonable investor to separate the wheat from the chaff when reviewing periodic reports and proxy statements. With this goal in mind, I have instructed the Division of Corporation Finance to engage in a comprehensive review of Regulation S-K. I welcome and encourage members of the public to provide their views on how the Commission can amend Regulation S-K, with the goal of revising the requirements to focus on eliciting disclosure of material information and avoid compelling the disclosure of immaterial information."
XBRL US' letter responded to the SEC request by noting, "U.S. capital markets are generally considered the most robust in the world, as characterized by size, liquidity, and transparency...While efficiency and reporting burden reduction are important, the disclosure regime established and maintained by the SEC is an important factor in the strength of U.S. markets compared to those in the rest of the world." We went on to point out that reporting in structured data format using XBRL has been supported by the Commission over the last 17 years, and we encouraged the SEC to continue this approach to the benefit of all capital market stakeholders. The SEC received more than 100 letters, both pro and con. While several commenters suggested a pullback in XBRL requirements, many were supportive of XBRL, including the London Stock Exchange Group, the US Impact Investing Alliance, Calcbench, Palm Beach Atlantic University, the AFL-CIO, the International Corporate Governance Network (ICGN), the Environmental Defense Fund, and Auditchain, among others.
Wall Street Blockchain Alliance and XBRL US announced partnership to promote efficiency and transparency in decentralized finance. The announcement explained that the partnership will focus on developing a proposed disclosure framework for digital assets as defined in the GENIUS Act and eventually, the CLARITY Act by leveraging WSBA's expertise in blockchain technology with XBRL US' experience and work developing and building open data standards for regulatory reporting. The Wall Street Blockchain Alliance (WSBA) is an industry leading non-profit trade association, with a mission to advocate, guide and promote comprehensive adoption of blockchain technology and cryptoassets across global markets.
"We're excited to partner with XBRL US to help advance greater alignment and clarity in how digital asset information is defined and shared. As the ecosystem continues to evolve, establishing common frameworks will be essential to supporting market integrity, improving transparency, and fostering more informed engagement between industry and regulators." noted Ron Quaranta, Chairman and CEO, Wall Street Blockchain Alliance.
