The U.S. Securities and Exchange Commission has sued a Texas entrepreneur it says raised $12.3 million from about 150 investors by promising profits from artificial-intelligence trading bots that did not exist. The case, filed on May 29, targets Nathan Fuller and his entities Privvy Investments LLC, Privvy Investments, and Gateway Digital Investments. From at least October 2022 through mid-2024, Fuller allegedly sold passive joint-venture interests in a crypto arbitrage operation powered by proprietary AI trading bots. Those bots, he told investors, could scan crypto markets around the clock, execute high-frequency arbitrage trades, and cap losses with stop-loss code. The pitch came with promises of returns between 40% to 50% within 30 to 45 days – and in some cases more than 100% in under a month.
In reality, the SEC says, the bots were neither artificial intelligence nor functional trading software. Only about $380,000 (roughly 3% ) of the money raised ever bought crypto, and those trades were made without the advertised bots and generated no profit. The rest was diverted.
Fuller's alleged scheme follows a pattern regulators have flagged repeatedly in 2026: fraudsters bolt fashionable AI branding onto old-fashioned investment scams. The SEC complaint describes a classic Ponzi structure dressed in technical jargon. Fuller allegedly misappropriated at least $6.2 million for personal use, including buying a home and spending on gambling, travel, and vehicles. Another $5.5 million went toward Ponzi-like payments, using fresh investor deposits to pay earlier backers.
When investors began asking to withdraw funds, Fuller leaned further into deception. He allegedly produced fabricated account statements showing fictitious gains, referenced entities that did not exist, and even used AI to generate a letter from a purported auditing firm claiming that investor accounts were under review and would later be liquidated into a trust.
The SEC's account of the money trail is stark. Here is where the $12.3 million went:
| Use of Funds | Amount | Percentage of Total |
|---|---|---|
| Actual crypto purchases | $380,000 | 3% |
| Personal spending (home, gambling, travel, vehicles) | $6.2 million | 50% |
| Ponzi payments to earlier investors | $5.5 million | 45% |
Only 3% of investor money ever touched a crypto exchange. The rest funded a lifestyle and a Ponzi mechanism that kept the scheme alive until new money dried up.
Fuller's pitch relied on a now-familiar prop: the AI trading bot. The label is difficult for retail backers to verify and easy to dress up with technical jargon. The SEC says the bots were neither AI nor functional trading software. They were a narrative device designed to justify promised returns that no legitimate strategy could deliver.
This case aligns with a broader enforcement wave. Last year, the SEC targeted an alleged AI trading kingpin behind a $198 million global Ponzi scheme. Prior to that, regulators charged four people over a $295 million global crypto Ponzi scheme that duped more than 100,000 investors. The Privvy complaint is comparatively small in dollar terms. It is emblematic of the AI angle examiners are now scrutinizing.
The SEC complaint lists several warning signs that were present from the start:
The case is a reminder that the crypto market remains fertile ground for fraud, especially when new technology buzzwords enter the mainstream. AI trading bots are the latest in a long line of props that include mining contracts, arbitrage funds, and token presales. The mechanism is always the same: promise high returns, collect money, pay early investors with new deposits, and spend the rest.
For traders and investors evaluating crypto opportunities, the practical takeaway is to focus on verifiable track records and auditable operations. Any entity that refuses to show real trading history, real P&L, or real withdrawal processes is not worth the risk. The SEC's action against Fuller is a civil case seeking permanent injunctions, disgorgement of ill-gotten gains plus interest, and civil penalties. Such cases can run in parallel with criminal investigations, though the complaint itself is a civil action.
If the SEC prevails, the remedies could include returning money to defrauded investors. Recoveries in Ponzi cases are frequently a fraction of the losses once funds have been spent on homes, gambling, and travel. The $6.2 million allegedly misappropriated for personal use is likely gone. The $5.5 million paid to earlier investors may be recoverable in theory. Clawbacks are difficult and time-consuming.
The matter now moves through the federal court system, where Fuller will have an opportunity to respond to the allegations. The SEC's case is part of a larger push by regulators to police AI-themed crypto schemes. For investors, the episode reinforces a simple rule: if the pitch relies on technology you cannot verify, the risk is not worth the promised return.
For those building watchlists or evaluating crypto exposure, the key question is not whether AI trading bots exist – they do, in some legitimate forms. The question is whether the entity offering them can prove they work. The SEC's complaint against Fuller provides a clear template of what to avoid: unregistered securities, guaranteed returns, and a founder who spends investor money on personal luxuries.
This case also highlights the importance of using regulated brokers and platforms when trading crypto. No platform can prevent fraud entirely. Regulated entities offer some recourse and transparency that unregistered schemes lack. For a list of platforms that meet regulatory standards, see our guide to best crypto brokers.

The SEC's action against Fuller is a civil enforcement case, not a criminal indictment. The pattern it reveals – AI branding, Ponzi mechanics, fabricated documents – is one that investors will see again. The question is whether the next pitch will be easier to spot.
