Summary
The Securities and Exchange Commission filed a civil enforcement action on May 29, 2026 against Nathan Fuller, the founder and sole member of Privvy Investments and an operator using the alias Gateway Digital Investments, alleging operation of a $12.3 million Ponzi scheme. The complaint identifies over 150 victims distributed across nine U.S. states and two additional countries, representing a geographically dispersed victim base that highlights the reach of crypto-based investment fraud.
Fuller's scheme centered on a false premise: he solicited investments from October 2022 through mid-2024 by claiming his entities offered access to proprietary AI-based trading algorithms and bots allegedly capable of executing high-frequency arbitrage trades on cryptocurrency exchanges. The promised returns were materially unrealistic—Fuller claimed investors could expect 40-50% returns within 30 to 45 days, with some promotional materials suggesting returns exceeding 100% were achievable in as little as 21 days. According to the SEC complaint, these AI bots did not exist.
The complaint alleges Fuller used investor capital for two primary purposes: personal enrichment and scheme sustainability. At least $6.2 million was misappropriated for Fuller's personal expenses, while $5.5 million was deployed to pay earlier investors in the classic Ponzi structure designed to maintain confidence in the platform and encourage additional capital deployment. This pattern is consistent with historical Ponzi schemes, where operator discretion over capital allocation becomes the mechanism for fraud.
This enforcement action reflects an apparent escalation in SEC scrutiny of AI-branded cryptocurrency investment schemes. The case demonstrates how emerging technology narratives—in this instance, artificial intelligence and algorithmic trading—are being weaponized to add credibility to unregistered investment offerings targeting retail and institutional investors. For institutional market participants evaluating cryptocurrency investment opportunities or assessing counterparty risk in digital asset platforms, this case reinforces the necessity of rigorous due diligence, independent verification of trading methodologies, and verification that investment vehicles carry appropriate regulatory registration and oversight.
