The Private-Markets Landscape and the Exemptions Map

Every offer and sale of securities must be registered with the SEC or fit an exemption, and most private capital flows through Regulation D, especially Rule 506(b). As of November 2026 the main limits are unlimited for Rules 506(b) and 506(c), $10 million per 12 months for Rule 504, $20 million for Regulation A Tier 1, $75 million for Tier 2 and $5 million for Regulation Crowdfunding.

Why exemptions matter

Every offer and sale of securities must either be registered under the Securities Act of 1933 or rely on an available exemption from registration ^[1]. Raising money from investors, unlike taking a loan or a grant, involves offering and selling securities, which is why the choice of pathway comes before almost every other decision in a raise ^[2]. A registered public offering requires a registration statement that must be effective before any sale, and after an IPO the company takes on ongoing public reporting ^[2]. Exempt offerings trade that burden for conditions on who may invest, how investors may be approached and how much may be raised.

The scale of the private market

SEC staff data for July 1, 2024 through June 30, 2025 show that, excluding pooled funds, companies raised about $378 billion under Rule 506(b), $24 billion under Rule 506(c), $300 million under Rule 504, $1.2 billion under Regulation A and $235 million under Regulation Crowdfunding, compared with $47 billion in initial public offerings ^[5]. In the same staff report, U.S. private companies raised 36% ($840 billion) of all capital raised by U.S. companies ^[5]. Pooled funds such as private equity and venture funds are counted separately, and they raised about $1.9 trillion under Rule 506(b) alone ^[5]. The takeaway is that Rule 506(b) is not a niche tool; it is the workhorse of U.S. private capital.

Section 4(a)(2): the statutory private placement

Section 4(a)(2) of the Securities Act exempts transactions by an issuer not involving any public offering ^[2]. To qualify, purchasers generally must be sophisticated or able to bear the investment's economic risk, must have access to prospectus-type information and must agree not to resell or distribute the securities to the public ^[2]. Public advertising and general solicitation are generally incompatible with the exemption, and because its limits come from court cases rather than SEC rules, its boundaries are less certain ^[2].

Regulation D: Rules 506(b), 506(c) and 504

Rule 506(b) is a safe harbor under Section 4(a)(2) that gives companies objective standards to rely on ^[2]. It permits an unlimited raise from accredited investors plus up to 35 non-accredited investors in any 90-calendar-day period, but it prohibits general solicitation ^[1][2]. Rule 506(c) also permits an unlimited raise and allows general solicitation, provided every purchaser is accredited and the company takes reasonable steps to verify that status ^[1][2]. Rule 504 permits up to $10 million of securities in a 12-month period, is often used for regional offerings and, unlike Rule 506, must comply with state registration requirements or a state exemption ^[1][2][8]. Reporting companies, investment companies, blank-check companies and bad actors cannot use Rule 504 ^[8]. All three rules require a Form D notice within 15 days after the first sale ^[1].

Regulation A: Tier 1 and Tier 2

Regulation A, sometimes called a mini-IPO, is an exemption for public offerings that share many characteristics with registered offerings ^[1][7]. The rule text caps Tier 1 at $20 million in a 12-month period, including no more than $6 million from selling securityholders who are affiliates, and Tier 2 at $75 million, including no more than $22.5 million from affiliate selling securityholders ^[3]. Tier 2 adds audited financial statements, ongoing reporting and, for non-accredited investors in offerings not listed on an exchange, a limit of 10% of the greater of annual income or net worth ^[2][3][7]. Tier 2 offerings do not need to be registered or qualified with state securities regulators, while Tier 1 offerings do ^[2][7]. Regulation A is available only to companies organized in, and with their principal place of business in, the United States or Canada ^[7].

Regulation Crowdfunding

Regulation Crowdfunding lets eligible companies raise up to $5 million in a rolling 12-month period online, through a single SEC-registered broker-dealer or funding portal ^[2][4]. Non-accredited investors face annual limits across all crowdfunding offerings: the greater of $2,500 or 5% of the greater of income or net worth if either is below $124,000, or 10% of the greater of the two, capped at $124,000, if both are at least $124,000 ^[4]. A petition for rulemaking dated July 13, 2026 (File No. 4-914) asks the SEC to raise the crowdfunding cap to $20 million with inflation indexing ^[6]. A petition is only a request; it does not change the $5 million limit unless the Commission proposes and adopts a rule.

• Rule 506(b): unlimited amount; no general solicitation; up to 35 non-accredited investors per 90 days ^[1][2].
• Rule 506(c): unlimited amount; general solicitation allowed; accredited purchasers only, with verification ^[1][2].
• Rule 504: up to $10 million per 12 months; state registration or exemption still required ^[2][8].
• Regulation A: Tier 1 up to $20 million; Tier 2 up to $75 million ^[3].
• Regulation Crowdfunding: up to $5 million per 12 months through one registered intermediary ^[4].
