The scheme is named after Charles Ponzi, who in 1920 promised Boston investors a 50% profit in 45 days. A century later, the same pattern drives billions of dollars in losses every year, now increasingly through cryptocurrency platforms, social media “investment clubs,” and messaging apps.

How Does a Ponzi Scheme Work?
A Ponzi scheme looks like an investment fund from the outside. Inside, money moves in a circle: new deposits are used to pay “returns” to earlier investors, and the operator keeps a share for themselves. Fake account statements make it look like the money is growing.
The Four Stages of a Ponzi Scheme
Ponzi Schemes and Investment Fraud: Latest Government Data
Federal agencies don’t track Ponzi schemes as a separate category. The FBI’s Internet Crime Complaint Center (IC3) counts them within investment fraud, which it defines to include Ponzi and pyramid schemes, retirement fraud, and 401(k) scams. That category has been the costliest type of internet crime for several years running, and losses nearly doubled between 2023 and 2025.
| Measure (FBI IC3, investment fraud) | 2023 | 2024 | 2025 |
|---|---|---|---|
| Reported losses, all ages | $4.57 billion | $6.57 billion | $8.65 billion |
| Complaints, all ages | 39,570 | 47,919 | 72,984 |
| Reported losses, age 60+ | $1.24 billion | $1.83 billion | $3.52 billion |
| Complaints, age 60+ | 6,443 | 9,448 | 16,926 |
What the 2025 Reports Show
- Crypto is now the main vehicle. The FBI received 61,559 complaints of cryptocurrency investment fraud in 2025, with $7.23 billion in losses: a 48% rise in complaints and a 25% rise in losses from 2024.
- Scams start on social media. The FTC reports people lost $1.1 billion in 2025 to investment scams that began on social media, often through ads for investing lessons or WhatsApp groups filled with fake “successful investors.”
- Older Americans lose the most. Investment fraud losses reported by people 60 and older nearly doubled in one year, from $1.83 billion to $3.52 billion.
- Total fraud keeps climbing. Americans reported $20.9 billion in internet crime losses to the FBI and $15.9 billion in fraud losses to the FTC in 2025. Investment fraud was the largest category in both.
Ponzi Scheme vs. Pyramid Scheme: What’s the Difference?
Both schemes pay early participants with later participants’ money, and both collapse. The difference is in how the money comes in and what participants believe they’re doing.
| Ponzi scheme | Pyramid scheme | |
|---|---|---|
| What it’s sold as | An investment: a fund, trading program, or private note | A business opportunity, often disguised as multi-level marketing |
| Who runs it | A central operator who controls all the money | Layers of participants, each recruiting the next level |
| How participants “earn” | Returns supposedly generated by the investment | Fees from people they personally recruit |
| Do participants recruit? | Not required; investors are often passive | Yes, recruiting is the whole model |
| What participants know | Usually believe their money is invested | Usually know income depends on recruiting |
| Typical charges | Securities fraud, wire and mail fraud, money laundering | Wire and mail fraud, FTC deceptive-practice actions, state fraud laws |
7 Warning Signs of a Ponzi Scheme

Recent SEC Ponzi Cases (Fiscal Year 2025)
The SEC’s FY2025 enforcement report highlighted two alleged Ponzi schemes aimed at everyday investors:
- Paramount Management Group / Prestige Investment Group and founder Daryl F. Heller: about 2,700 investors and roughly $400 million in losses (alleged).
- First Liberty Building & Loan and owner Edwin Brant Frost IV: about 300 investors defrauded of more than $140 million (alleged).
These cases are allegations. Defendants are presumed innocent unless proven otherwise.
Is a Ponzi Scheme Illegal? Federal Charges and Penalties
There is no single federal “Ponzi scheme” statute. Prosecutors charge the conduct under several fraud and financial-crime laws, usually stacking counts for each wire transfer, mailing, or transaction. The SEC can bring a parallel civil case at the same time.
| Charge | Statute | Maximum prison term (per count) |
|---|---|---|
| Wire fraud | 18 U.S.C. § 1343 | 20 years (30 if a financial institution is affected) |
| Mail fraud | 18 U.S.C. § 1341 | 20 years (30 if a financial institution is affected) |
| Securities fraud | 18 U.S.C. § 1348 | 25 years |
| Securities Exchange Act fraud (Rule 10b-5) | 15 U.S.C. §§ 78j(b), 78ff | 20 years; fines up to $5 million (individuals) or $25 million (entities) |
| Money laundering | 18 U.S.C. §§ 1956, 1957 | 20 years (§ 1956); 10 years (§ 1957) |
| Investment adviser fraud | 15 U.S.C. §§ 80b-6, 80b-17 | 5 years |
| Commodities fraud (futures, some crypto) | 7 U.S.C. § 13 | 10 years |
| Conspiracy to commit fraud | 18 U.S.C. § 1349 | Same as the underlying offense |
How Sentences Are Actually Calculated
Statutory maximums are rarely the deciding factor. Federal judges start with the U.S. Sentencing Guidelines, and for fraud the biggest driver is the loss amount. Under the guidelines’ loss table, a scheme with losses above $550 million adds 30 offense levels. Additional increases apply for large numbers of victims, victims who suffered substantial financial hardship, sophisticated means, and abuse of a position of trust. That’s why Ponzi sentences of 50 to 150 years are possible.
Restitution, Forfeiture, and SEC Penalties
- Restitution: Courts must order defendants to repay victims’ losses in most federal fraud cases.
- Forfeiture: The government can seize property traceable to the scheme, including homes, cars, and bank accounts.
- SEC civil remedies: Disgorgement of profits, civil penalties, asset freezes, court-appointed receivers, and industry or officer-and-director bars. In FY2025 the SEC obtained orders for $17.9 billion in total monetary relief, including judgments in the long-running Stanford Ponzi case.
Can Ponzi Scheme Investors Be Forced to Pay Money Back?
Yes. After a Ponzi scheme collapses, a court-appointed receiver or bankruptcy trustee works to recover money for the victims, and that includes suing investors who got out with more than they put in.
- “Net winners” (investors who withdrew more than they deposited) can be sued to return their “profits,” because those profits were really other investors’ money.
- Good-faith investors can generally keep the amount of their original principal, but must return fictitious profits.
- Investors who knew, or should have known, about the fraud can lose their principal too, along with the profits.
- Promoters and feeder funds who brought in investors and were paid commissions face clawback claims, SEC actions, and sometimes criminal charges, even if they say they didn’t know it was a fraud.
Clawback deadlines depend on federal bankruptcy law and state fraudulent-transfer laws, and they can reach back several years. If you received a demand letter from a receiver or trustee, get legal advice before you respond.
