The U.S. Securities and Exchange Commission has charged Nathan Fuller, a resident of Cypress, Texas, with orchestrating a fraudulent cryptocurrency investment scheme that raised approximately $12.3 million from roughly 150 investors through false claims of AI-powered trading bots.
The complaint, filed May 28 in the U.S. District Court for the Southern District of Texas, alleges that Fuller operated the scheme through Privvy Investments LLC and related business names from October 2022 through mid-2024. At the heart of the pitch was a promise of proprietary artificial intelligence bots executing high-frequency arbitrage trades across crypto markets.
According to the SEC, Fuller told investors his AI trading bots could scan cryptocurrency exchanges, execute profitable arbitrage trades automatically, and limit downside risk through algorithmic stop-loss coding. Investors were promised returns of 40% to 50% within 30 to 45 days — and in some cases, guaranteed profits exceeding 100% in less than a month.
None of it was real.
## How the Alleged Scheme Worked
The SEC’s complaint paints a stark picture of how the **AI crypto arbitrage scam SEC** investigators uncovered operated under the guise of technological sophistication.
Fuller allegedly marketed passive joint-venture interests in a purported crypto arbitrage trading operation. He claimed investor funds would be deployed through AI-driven trading strategies that could capture price discrepancies across exchanges faster than any human trader. He further assured investors their capital was protected by insurance and bonding arrangements.
In reality, only about $380,000 — roughly 3% of the total funds raised — was ever used to purchase cryptocurrency. Those trades were conducted manually, without any AI bots, and generated no profits.
The remaining funds were misappropriated. The SEC alleges Fuller diverted at least $6.2 million for personal expenses, including purchasing a home, gambling, travel, and vehicles. An additional $5.5 million was used to make Ponzi-like payments to earlier investors — a hallmark of pyramid-style fraud where new investor money is used to pay fake returns to earlier participants.
## Fabricated Documents and AI-Generated Deception
As investor withdrawal requests mounted, the SEC says Fuller escalated his deception. He allegedly created fabricated account statements showing artificial gains, referenced fictitious entities to maintain credibility, and — in a particularly ironic twist — used artificial intelligence to generate a letter from a purported auditing firm.
The fake letter claimed investor accounts were under review and would later be liquidated into a trust, buying Fuller additional time as the scheme unraveled.
The SEC charged Fuller with violating registration and antifraud provisions of federal securities laws. The agency is seeking permanent injunctions, disgorgement of ill-gotten gains with prejudgment interest, civil penalties, and a ban on Fuller participating in any future securities offerings.
## A Pattern of Fraud
This is not Fuller’s first encounter with legal consequences related to the scheme. In September 2025, a Texas bankruptcy court denied Fuller a discharge of over $12.5 million in debt after he admitted that Privvy Investments operated as a Ponzi scheme and that he had fabricated a large portion of supporting documents.
The parallel bankruptcy and SEC enforcement actions highlight the extent of the alleged fraud. The Department of Justice has also been involved, with court records showing Fuller admitted to operating a Ponzi scheme during bankruptcy proceedings.
## Broader Implications for AI-Themed Crypto Fraud
The case marks another chapter in what regulators describe as a rising trend of fraudsters using AI hype to lend legitimacy to investment schemes. The rapid adoption of generative AI tools has created new opportunities for bad actors to fabricate believable marketing materials, fake audit letters, and convincing pitch decks — all of which Fuller allegedly employed.
SEC enforcement actions against AI-washing in crypto have intensified over the past year. The regulator has consistently warned investors that terms like “AI-powered,” “algorithmic trading,” and “automated arbitrage” do not substitute for genuine regulatory compliance, transparent operations, or audited financials.
For retail investors, the Fuller case serves as a cautionary tale: promises of guaranteed triple-digit returns, particularly when packaged with trendy AI buzzwords, remain one of the oldest red flags in financial fraud — now wearing a new coat of paint.
