Pre-IPO investment scams and how to recognise them

By Unicorn Private Research. Published and last updated 26 September 2026.

Both US market watchdogs keep a public alert on pre-IPO fraud running. The Securities and Exchange Commission's version, Pre-IPO Investment Scams, came out on 7 June 2024 from its Office of Investor Education and Advocacy. FINRA followed on 18 August 2026 with Know the Risks of Pre-IPO Funds and Potential Fraud. Neither calls pre-IPO investing a scam in itself. Their point is narrower: the shares are hard to price and hard to verify, and that is exactly what draws fraudsters.

The seven warning signs in the SEC alert

The SEC lists seven signals. A fraudulent offer rarely shows just one.

1. Unregistered sellers. Whoever is offering the shares holds no licence or registration as an investment professional.
2. Aggressive selling. Cold calls, a script, and a push to cash out a retirement account.
3. Social media pitches. The SEC is blunt here: never decide on an investment based only on what you saw on a social platform or an app.
4. Trending topics. The offer gets hooked to whatever is in the headlines, today artificial intelligence and crypto assets.
5. False or misleading claims. Comparisons with companies that made it, with nothing to back them, an IPO said to be just around the corner, or "no upfront fees" with a markup nobody mentions.
6. Hidden background. The people behind the deal keep their names out of it, sometimes because a regulator has disciplined them before.
7. Unregistered offerings. The offering was never registered, and no exemption covers it.

What FINRA warns about when the deal is real

FINRA's August 2026 note deals with a different way to lose money: an offering that is genuine and simply bad.

• The company may never list.
• With no continuous market price, nobody can say with confidence what the shares are worth.
• You cannot easily sell them, because no ready secondary market exists.
• There may be several layers of ownership between you and the actual shares.
• Before you make a cent, the purchase costs have to be earned back.
• The company can block the transfer, and then the transaction is void.

Five minutes of checking

Most fake pre-IPO offers fail at least one of these tests. None of them costs anything.

1. Look the seller up on FINRA BrokerCheck and in the SEC's investment adviser database.
2. Get it in writing: what exactly are you buying? The shares themselves, a stake in a special purpose vehicle, or a contractual promise of delivery later?
3. Ask who holds the shares today and whether the company has signed off on the transfer.
4. If the seller claims a US exemption, search EDGAR for the issuer's Form D.
5. Send money only to a regulated entity or an escrow account. Never to a person.
6. A "confirmed" IPO date is a red flag unless the company has filed publicly itself.

What a real offering looks like

A legitimate pre-IPO deal is slow, papered and run through intermediaries. You get a named, regulated counterparty and an offering document that spells out the structure and the fees. The transfer goes through the issuing company, and eligibility rules shut out most retail investors. In the US that usually means being an accredited investor, which the SEC defines as an individual with net worth over one million dollars excluding the primary residence, or income over 200,000 dollars individually or 300,000 dollars jointly in each of the prior two years. An offer that skips all of that and lands in your direct messages is no shortcut. It is something else entirely.
