Rule 506(b) bars public solicitation; Rule 506(c) permits it but requires verifying every investor is accredited. On 12 March 2025, SEC staff accepted high minimum investments — US$200,000 for individuals, US$1,000,000 for entities — plus written representations as sufficient verification. That is staff guidance, not law, and as of 7 August 2026 most offerings still use 506(b).

If you run a fund from London, Singapore, Dubai, or anywhere outside the United States, you have probably heard two contradictory things about raising from U.S. investors in 2026: that the SEC has "opened up" private-fund marketing, and that U.S. securities law remains a minefield. Both are half true. This article explains the actual choice between the two U.S. private-placement paths — Rule 506(b) and Rule 506(c) — what a five-page letter from the SEC's staff changed in March 2025, what it deliberately did not change, and what the SEC's own filing data says fund managers are actually doing. It is written for managers who did not grow up inside the U.S. system, so terms are defined as they appear.

What is the actual difference between SEC Rule 506(b) and 506(c)?

Both rules live inside Regulation D, the framework U.S. securities law provides for selling investment interests privately, without registering a public offering with the SEC (the U.S. Securities and Exchange Commission, the federal securities regulator). Nearly every private fund that takes U.S. investors relies on one of these two rules. They differ on a single variable: publicity.

Rule 506(b) is the traditional, quiet path. You may raise unlimited amounts from accredited investors — a category that includes essentially every institution a fund manager wants, from pensions to endowments to family offices — but you need a preexisting substantive relationship (PSR) and cannot engage in "general solicitation": no public advertising, no open websites describing the offering, no mass outreach to strangers. In practice, investors confirm their own accredited status in the subscription documents, because the rule turns on the issuer's reasonable belief. The rule technically permits up to 35 non-accredited investors, but institutional funds never use that allowance — admitting even one triggers a disclosure package built for a different world.

Rule 506(c) was created in 2013 to permit the opposite: you may solicit publicly — advertise, publish, speak openly about the offering — but in exchange, every purchaser must actually be accredited, and you must take "reasonable steps to verify" that status rather than simply accepting a signature. For a decade, that verification requirement was the reason most fund managers stayed away.

Is pitching at a closed-door investor conference "general solicitation"?

This is the question working GPs ask most about 506(b), and the industry's standard answer — the doors were closed and the LPs were invited, so it was never the general public — is directionally correct but rests on a subtler foundation than most managers realize. The load-bearing element is not the closed door; it is how the room was assembled. An event whose attendees arrived through pre-existing, screened relationships — the organizer genuinely knows who is in the room, and the event was not promoted through what SEC staff call "impersonal, non-selective means of communication" — is the classic non-solicitation pattern. Longstanding staff guidance recognizes that investor relationships built through a qualified intermediary before an offering can carry this weight, and the same March 2025 staff package discussed below refreshed the guidance on referrals through established investor networks and on demo-day events.

Three calibrations keep the comfort honest. First, a codified carve-out for multi-issuer pitch events does exist — Rule 148, adopted in 2021 — but its sponsor list is narrow (universities, governments, nonprofits, angel groups, incubators, and accelerators, essentially uncompensated), so the typical commercial cap-intro conference sits outside any written rule; its comfort is facts-and-circumstances, which is real but not a safe harbor. Second, a publicly advertised event with open registration is on the wrong side of the line no matter what happens inside the room — a closed door does not cure an open invitation, and neither does a disclaimer. Third, under 506(c) none of this matters: solicit from any stage you like, with verification at the point of sale. Under 506(b), the discipline is to ask how the audience was assembled before accepting the podium — and to keep what you present at manager level, with the fund-specific conversation happening one-to-one afterward.

What did the March 2025 no-action letter change?

Here is what happened, precisely, because the details are routinely garbled in secondhand accounts.

On 6 March 2025, the law firm Latham & Watkins wrote to the SEC's Division of Corporation Finance proposing a simpler way to satisfy 506(c) verification. On 12 March 2025, the Division's staff responded that, based on the representations in Latham's letter, an issuer could reasonably conclude it has taken reasonable steps to verify accredited status where three conditions are met:

1. A high minimum investment. At least US$200,000 for a natural person, or US$1,000,000 for an entity. A binding capital commitment, called in installments over time, counts — the standard closed-end fund structure fits without modification.
2. Two written representations from the investor: that they are accredited, and that their minimum investment is not financed by a third party for the specific purpose of making this particular investment. Ordinary credit facilities and commitments that predate the offering do not violate this — the condition targets purpose-built financing of the minimum itself.
3. No contrary knowledge. The issuer must have no actual knowledge of facts suggesting either representation is false.

One attribution detail worth getting right, because most coverage gets it wrong: the dollar figures come from Latham's request letter, not from the SEC. The staff's response contains no dollar amounts at all — it agreed that the approach as Latham described it was reasonable. That distinction matters for how much weight the numbers can bear, as we will see below.

Before March 2025, the practical verification methods were documentary: collecting investors' tax forms, bank and brokerage statements, or confirmation letters from their advisers — paperwork that institutional investors resented and many managers refused to request. The letter replaced that friction, for large-ticket investors, with two sentences in a subscription agreement.

Why does this matter more for fund managers than for startups?

Most commentary on the letter was written for U.S. startups. For fund managers — especially non-U.S. fund managers — it matters more, for a structural reason almost nobody states.

The verification safe harbors written into Rule 506(c) itself only ever covered natural persons. There was never a codified checklist for verifying a pension fund, an insurance company, or a sovereign investor. Funds selling to institutions always had to rely on the rule's "principles-based" standard — a reasonableness judgment with no objective anchor. The March 2025 letter supplied that anchor: an institutional LP writing a seven-figure ticket, representing its own status, is now squarely within a described, staff-endorsed pattern.

And since January 2026, SEC staff have confirmed that an issuer may mix verification methods within a single offering — the minimum-investment route for institutional commitments, documentary methods for smaller individual tickets, in the same closing. For a non-U.S. manager whose U.S. investor list is a handful of institutions and a few individuals, that resolves the last practical objection.

There is a second reason this lands differently for managers outside the U.S.: the older 506(b) path rewards managers who already have preexisting substantive U.S. relationships, because it requires that investors be reached without public solicitation. A manager with no existing U.S. network faced a structural disadvantage that 506(c) — now workable — removes.

So has everyone switched to 506(c)?

No — and this is where the honest data separates this article from the cheerleading.

The SEC publishes statistics on every Form D filing (the short public notice filed for each Regulation D offering). Through the first quarter of 2026, the picture is unambiguous:

Source: SEC Division of Economic and Risk Analysis, Regulation D statistics, published 30 June 2026.

Read the first column: the share of offerings choosing 506(c) has sat in the same narrow band — roughly 11 to 12 percent — every quarter for four years, with no break after March 2025. Roughly nine in ten Regulation D offerings still proceed the quiet way, under 506(b).

Now read the last column: the average 506(c) offering nearly doubled in size between the quarter the letter was issued and the first quarter of 2026, reaching a series high of US$56.4 million. That is the letter's real signature. It did not persuade more issuers to advertise. It made 506(c) viable for larger, institutional-scale raises — precisely the offerings that could never use the old natural-person checklists and needed an entity-sized anchor.

The takeaway for a non-U.S. manager: the 506(b)-versus-506(c) choice is not obsolete. It is a live decision whose economics changed at the institutional end. If you are told "everyone uses 506(c) now," you are being told something the SEC's own data contradicts.

What are the limits nobody quotes?

The law-firm alerts that covered the letter in March 2025 mostly noted its limits in passing. They deserve more than passing notice, because they define what the relief can and cannot carry.

It is staff guidance, not law. The letter says so itself, in language worth reading in full:

"This letter reflects the views of the staff of the Division of Corporation Finance. It is not a rule, regulation, or statement of the Commission... This letter, like all staff statements, has no legal force or effect: it does not alter or amend applicable law, and it creates no new or additional obligations for any person. Because the Division's views are based on the representations in your letter, any different facts or conditions might require the Division to reach a different conclusion."

Three practical consequences follow. First, the position can be withdrawn or narrowed without any rulemaking process — staff guidance changes at staff discretion. (For now, the direction is the opposite: the staff extended the position twice, in January 2026 and July 2026.) Second, it is representation-bound: stray from the described fact pattern and you are outside it.

Third — a genuinely overlooked detail — the letter's categories cover investors accredited under specific definitional prongs, and status-based institutions like banks, insurers, and public pension plans are not among them. Those investors are easily verified by other means, since their accreditation follows from what they are rather than what they own. But an issuer that runs the letter's representation script for an insurer is operating outside the letter's four corners, and should know it.

The rule itself never changed. Rule 506(c)'s text — including the verification requirement — is the same today as in 2021. What changed is the staff's view of one way to satisfy it.

What never changed at all?

This is the section to read twice, because the gap between "the SEC is permissive now" and reality is where enforcement risk lives — and that risk survives any change of administration.

• General solicitation is still a defined, regulated concept. Choosing 506(b) still means no public offering activity, from the first conversation.
• Verification is still required under 506(c). It is easier to satisfy. It did not disappear.
• Form D still gets filed — within 15 days of the first sale — and it is public. It discloses your offering size, amount raised, minimum investment, and which exemption you chose. Competitors and data vendors read it.
• Bad-actor disqualification still applies. A fund must screen its own people and anyone compensated to solicit — a disqualifying event in that chain can destroy the exemption.
• The adviser and broker-dealer regimes were never loosened. Who may manage, and who may be paid to solicit, are separate bodies of law the letter does not touch. A non-U.S. manager's registration analysis, and the rules about placement agents and finders, are exactly what they were in 2024.

A manager who reads "the SEC is loose now" as "anything goes" is confusing one staff position on one verification question with a rewrite of the U.S. securities laws that never happened.

As a non-U.S. manager, which should I use?

There is no universal answer, but the decision factors are consistent:

• Your U.S. investor list. All-institutional, large tickets, sourced through relationships? 506(b)'s quiet path may cost you nothing — publicity you were not going to use anyway. A thinner U.S. network, or a strategy that benefits from open visibility, argues for 506(c).
• Your offshore tranche. Most non-U.S. funds sell to home-market investors under Regulation S alongside the U.S. sleeve. That structure is integration-safe — but whether public 506(c) solicitation is compatible with a concurrent Regulation S offering is a question U.S. regulators have left open since 2013. Managers running both tracks conservatively keep the U.S. sleeve under 506(b). We cover this in detail in the concurrent-offering guide.
• Your European obligations. A public 506(c) campaign visible in the EEA can count as marketing under European rules and burn your reverse-solicitation position there. U.S. permission is not EU permission — see our companion piece on how U.S. general solicitation can close European doors.
• Your home-market rules. Rule 506(c) preempts nothing outside the U.S. Advertising restrictions in your own jurisdiction apply with full force.

Whichever exemption a manager chooses, the meetings themselves still come from relationships — which is the part no exemption files for you.

Frequently asked questions

Do I still need investors' tax returns or bank statements for 506(c)? Not necessarily. Since 12 March 2025, SEC staff accept that a high minimum investment (US$200,000 for individuals, US$1,000,000 for entities) plus written representations can satisfy verification, absent contrary knowledge. The documentary methods remain available and still serve smaller tickets.

Are the US$200,000 / US$1,000,000 figures an SEC rule? No. They come from Latham & Watkins's request letter; the SEC staff response endorsed the approach based on those representations. It is staff guidance with no legal force — reliable in practice today, revocable without rulemaking.

Can I mix verification methods in one offering? Yes. SEC staff confirmed in January 2026 that different investors in the same 506(c) offering may be verified by different methods.

Is 506(b) dead? No. By offering count, roughly 88–89% of Regulation D offerings still proceed under 506(b) (SEC data through Q1 2026). 506(c) adoption grew in deal size, not deal count.

Does a capital commitment count toward the minimum, or must cash be wired? A binding commitment called in installments qualifies — the ordinary closed-end fund structure fits the letter's terms.

Does 506(c) let me advertise to European or Asian investors too? No. Rule 506(c) is a U.S. exemption; marketing into the EU, U.K., or Asia is governed by those jurisdictions' rules regardless of U.S. compliance — and EEA-visible fund promotion can undermine EU reverse solicitation.

Is presenting at an invitation-only investor conference general solicitation? Generally not, on typical facts — where attendees were invited through pre-existing, screened relationships and the event was not publicly promoted. The analysis is fact-specific and turns on how the audience was assembled, not on the closed door itself. The codified demo-day carve-out (Rule 148) covers only narrow sponsor types, so commercial cap-intro events rest on facts and circumstances. Ask counsel before the podium, not after.

Can the SEC take the 2025 relief back? Yes — staff positions can be withdrawn or narrowed without notice-and-comment rulemaking. As of 7 August 2026 the staff has extended the position rather than trimmed it, but managers and their counsel should track it as posture, not law.
