Pre-IPO vs. SPV vs. private placement vs. Regulation D
| Term | What it is | What you actually own | Key risk |
|---|---|---|---|
| Pre-IPO shares | Stock in a private company that hasn't gone public | Company shares, if bought directly and the transfer is approved | Illiquid; transfer restrictions; may never IPO |
| SPV | An LLC or LP formed to pool money for one investment | A membership or LP interest in the SPV | Extra fees; depends on the manager |
| Private placement | Any securities sale exempt from SEC registration | Whatever the offering documents describe | Limited disclosure; no SEC review |
| Regulation D | The SEC rules most private placements rely on | N/A (a legal exemption, not a product) | Exemption can be lost if rules are broken |
Regulation D: Rules 504, 506(b), 506(c), and 506(d)
| Item | Rule 504 | Rule 506(b) | Rule 506(c) |
|---|---|---|---|
| Maximum raise | $10 million in 12 months | Unlimited | Unlimited |
| Advertising / general solicitation | Limited; depends on state | Not allowed | Allowed |
| Who can invest | Any investor (state rules apply) | Unlimited accredited + up to 35 sophisticated non-accredited | Accredited investors only |
| Verification of accredited status | Not required | Reasonable belief | Reasonable steps to verify required |
| State registration | Generally required | Preempted; state notice filing | Preempted; state notice filing |
| Bad actor rule (506(d)) | Applies | Applies | Applies |
Rule 506(b) allows unlimited raises but no advertising or cold solicitation; offers generally go to people with a pre-existing, substantive relationship with the issuer or its broker. Rule 506(c) allows public advertising, but every buyer must be accredited and the issuer must take reasonable steps to verify it. In March 2025, SEC staff indicated a high minimum investment (for example, $200,000 for an individual) plus written representations can be a reasonable verification step in some circumstances. Rule 506(d), the bad actor rule, disqualifies an offering if the issuer or covered persons (officers, directors, 20% owners, promoters, paid solicitors) have certain securities-related convictions, injunctions, or bars.
Issuers file a Form D with the SEC, generally within 15 days after the first sale. It is a notice, not an approval, and is searchable on EDGAR.
Can an unregistered securities offering be legal?
Yes. "Unregistered" usually means "exempt," and that is legal. Unregistered securities fraud occurs when an offering is neither registered nor validly exempt, for example when a 506(c) offering sells to non-accredited investors or a 506(b) offering is cold-called to strangers, or when the people selling it are unregistered brokers. Investors in an offering that lost its exemption may have a right to rescission (to undo the purchase).
Regulation D investment fraud: what to watch for
- Cold calls or ads for an offering that claims Rule 506(b)
- A 506(c) offering that never asked you to prove accredited status
- A PPM whose fee and risk sections don't match what the salesperson said
- Form D "related persons" with disciplinary histories
- Sales commissions paid to people who aren't registered (check the Form D's sales compensation section)
Private equity investment scams
The same patterns appear in private equity, private credit, and real estate offerings sold to individuals: high-pressure sales, undisclosed fees, and managers using investor money for their own benefit. The verification steps on this site apply to any private placement.
How to report misleading private placement documents
