America’s top financial regulator wants to make going public easier, cheaper, and faster. The changes could reshape how companies raise money for years to come.
On May 19, 2026, the U.S. Securities and Exchange Commission unveiled what it describes as the most significant overhaul of public market rules in over twenty years. The proposal — a sweeping package of rule and form amendments under the Securities Act of 1933 — aims to facilitate capital formation in public securities markets by expanding issuer eligibility for key registration forms, modernizing how companies communicate with investors, and eliminating duplicative regulatory burdens that have increasingly driven issuers toward private markets.
The timing is deliberate. The reforms come amid ongoing concerns in Washington and on Wall Street that the number of publicly traded companies in the United States has declined significantly over the past two decades, as firms increasingly rely on private capital rather than pursuing traditional stock market listings. In the early 1990s, more than 7,800 companies were listed on U.S. exchanges. Last year, there were just 374 IPOs — a fraction of that era’s activity.
SEC Chairman Paul Atkins has a slogan for his agenda: “Make IPOs Great Again.” In his statement, Atkins said the proposals “build upon the legislative and regulatory concepts that have proven successful in the past and aim to extend that success to more companies — particularly small and mid-sized companies — and incentivize them to go and stay public.”
Shelf Offerings: A Game-Changer for Newly Public Companies
One of the most impactful changes involves shelf registrations — a financing tool that allows companies to pre-register securities with the SEC and sell shares when market conditions are favorable. Under current rules, a company must wait roughly one year after its IPO and maintain at least $75 million in publicly available shares before accessing this process.
The SEC has proposed eliminating both the current 12-month Exchange Act reporting requirement and the $75 million public float threshold for unlimited primary offerings. In plain terms, this means newly listed companies could tap public markets for additional capital almost immediately after their IPO — without being held hostage to arbitrary waiting periods or float requirements.
The shelf registration process has been a great success for seasoned, larger public companies, but newly public and smaller companies have not been able to fully use it due to eligibility requirements regarding the length of time a company has been public and its public float. Those barriers, the SEC argues, are relics of an era when filings were submitted on paper.

Raising the Bar for “Large Accelerated Filer” Status
The second major proposal targets how companies are categorized for reporting and disclosure purposes. Currently, a company with a $700 million public float is classified as a “large accelerated filer” — triggering the most stringent reporting obligations, including expensive external auditor attestations on internal financial controls.
The proposed amendments would raise that threshold from $700 million to $2 billion, and a company would not become a large accelerated filer for at least 60 months following its IPO regardless of its public float — effectively providing an “IPO on-ramp” to stabilize and grow while benefiting from disclosure scaling and other accommodations.
This five-year grace period is significant. Under the current system, a startup that rockets in valuation shortly after listing can suddenly find itself buried under compliance requirements designed for corporate giants. The proposed changes would also eliminate the possibility of filer status shifting based on short-term stock price changes, reducing unpredictable compliance obligations.
All other public companies would be categorized as non-accelerated filers and would benefit from nearly all disclosure scaling and other accommodations currently available to smaller and emerging companies — and all non-accelerated filers would also be exempt from the requirement to obtain an auditor’s attestation on their internal control over financial reporting.

Who Benefits — and How Broadly
The ripple effects of these changes could be far-reaching. The proposed rule amendments would extend disclosure scaling and other accommodations to approximately 81 percent of all current public companies. That’s a massive expansion from the roughly 36% that qualify today.
Companies already eyeing the public markets stand to benefit most immediately. Elon Musk’s SpaceX is expected to begin trading as early as next month, and high-profile AI companies like Anthropic and OpenAI are widely anticipated IPO candidates. The five-year on-ramp from strict reporting requirements could make a public listing far more palatable for these firms, which currently enjoy the flexibility of staying private.
The crypto sector, too, could see a material impact. Companies like Circle and Bullish have recently completed major public debuts, while others like Kraken have explored IPO plans. For crypto businesses operating in volatile markets, the ability to raise additional capital via shelf offerings without waiting for a set period after listing could allow them to capture windows of strong investor demand they might otherwise miss entirely.
What Comes Next
The SEC may revise the proposals based on public input before voting on whether to adopt the changes permanently. The public comment period runs for 60 days following publication of the proposals in the Federal Register.
Chairman Atkins has made clear this is just the beginning. Future proposals to transform the public company regulatory framework — including reforming the Regulation S-K disclosure requirements with materiality as its north star — will build on the foundation laid by today’s proposals.
Whether the changes succeed in reversing America’s decades-long IPO drought remains to be seen. But for the first time in a generation, the rules governing how companies go public are genuinely up for rewrite.
