The U.S. Securities and Exchange Commission has charged a Cypress, Texas, man with orchestrating a crypto-focused investment fraud that drew roughly $12.3 million from about 150 investors by falsely claiming to operate AI-powered trading bots capable of delivering guaranteed gains. The SEC’s complaint—filed in the U.S. District Court for the Southern District of Texas—names Nathan Fuller and his entities Privvy Investments, LLC, and Gateway Digital Investments, alleging a multi-year scheme that spanned at least October 2022 to mid-2024.
According to the SEC, Fuller promised investors returns of 40% to 50% within 30 to 45 days, with some pushes suggesting guarantees of profits exceeding 100% in as little as 21 days. He purportedly backed these claims by asserting that investor funds were secured by a surety bond, insured by the Federal Deposit Insurance Corporation (FDIC), and protected by a professional liability policy. The SEC contends that none of these assurances were true, and that the marketing hinged on exaggerated, misleading assurances rather than verifiable trading performance.
Key takeaways
- Approximately $12.3 million was raised from about 150 investors through Privvy Investments and Gateway Digital Investments, according to the SEC complaint.
- Fuller allegedly promised outsized short-term returns—40% to 50% in 30–45 days, with some investors told they could secure more than 100% profits in as little as 21 days—based on AI-driven trading bots that allegedly did not function as claimed.
- The marketer claimed funds were secured by a surety bond, FDIC insurance, and professional liability coverage; the SEC alleges these representations were false.
- More than half of the raised funds—at least $6.2 million—were allegedly used for Fuller’s personal expenses, with about $5.5 million diverted to make Ponzi-like payments to earlier investors.
- Investors received fake account statements and fabricated correspondence from fictitious entities to sustain the illusion of activity and profitability.
What the SEC alleges Fuller did and did not deliver
The core of the SEC’s case rests on a pattern of misrepresentation surrounding the use of artificial intelligence in trading. Fuller pitched proprietary AI-based bots that would conduct high-frequency arbitrage across crypto platforms. The complaint asserts that “Fuller’s bots did not function as represented,” undermining the central claim of guaranteed, AI-generated profits. By coupling the purported technology with promised protections like a surety bond and FDIC backing, the scheme sought to reassure risk-averse investors while masking its true operational status.
As described in the complaint, the marketing material allegedly painted an image of automated, professional-grade trading that could produce reliable returns even in volatile markets. The SEC contends that this marketing was designed to obscure the lack of any verifiable trading track record and to maintain liquidity in the scheme as new investors funded the payouts to earlier participants.
Financial flows and investor deception
From a financial perspective, the scheme’s cash movements paint a telling picture of its inner workings. Of the total $12.3 million raised, the SEC says Fuller misappropriated at least $6.2 million for personal use. An additional roughly $5.5 million reportedly went toward Ponzi-like payments to earlier investors, a classic feature used to prop up the illusion of steady returns and to prolong the lifecycle of the scheme. To maintain credibility, Fuller is alleged to have issued fake account statements and created correspondence from non-existent entities, enabling him to present a veneer of legitimacy to unsuspecting participants.
The allegations suggest a deliberate attempt to replicate the quasi-professional aura of legitimate asset management operations while exploiting the credibility of AI branding to entice retail investors. The use of fabricated documents and fictitious entities underscores a broader issue in crypto fraud: the ease with which persuasive presentation can mask actual performance that never materialized.
Regulatory context and what comes next
The Fuller case sits within a broader pattern of enforcement activity at the intersection of AI branding, crypto, and securities-like promises. Earlier this year, the SEC charged three purported crypto asset trading platforms and four investment clubs in a separate $14 million scheme that also leaned on AI branding to lure retail investors, with fraudsters using messaging apps to tout supposed AI-generated trading tips. The concurrent wave of actions illustrates the agency’s heightened focus on AI-enabled misrepresentations within crypto-adjacent investment strategies.
The SEC has signaled a more nuanced approach to crypto enforcement, acknowledging in its enforcement results that some actions over the past years did not always align cleanly with investor harm or traditional securities-law interpretations. In a 2025 update on enforcement, the agency noted that it had brought 95 actions and secured about $2.3 billion in penalties for issues like book-and-record violations that, in some cases, didn’t directly translate into demonstrable investor harm or protection. The regulator’s stance remains in flux as the crypto landscape evolves, particularly with the increasing convergence of AI and digital assets.
In Fuller’s case, the SEC is seeking permanent injunctions, disgorgement of ill-gotten gains, and civil penalties. The action underscores the agency’s willingness to pursue individuals who leverage AI narratives and crypto-like instruments to extract funds from retail investors under false pretenses. The case also serves as a cautionary tale for vendors, brokers, and social platforms that amplify or amplify-signal fraudulent schemes by enabling marketing claims that may misrepresent actual capabilities or protections.
What investors should watch next
As the SEC pursues its case, readers should monitor developments around investor restitution, the timeline for potential settlements or judgments, and the status of Fuller’s operational entities. The broader takeaway for investors is the importance of scrutinizing claims around AI-driven strategies, guarantees of short-term returns, and promised insurance or backing. When a seller makes extraordinary promises tied to technology—especially in a relatively new space where verifiable performance data is scarce—investors should demand concrete, auditable performance records, independent custodians, and clear disclosures about risk and liquidity.
Looking ahead, the industry will likely see continued scrutiny of AI branding in crypto-related solicitations, with regulators seeking clearer boundaries between legitimate automated trading tools and deceptive marketing that implies guaranteed results. For traders and users navigating the space, the message remains: verify, verify again, and rely on independently verifiable performance and regulatory compliance rather than promotional narratives built on AI mystique.
