Summary
David Choi's Mars FX US LP presented a compelling investment thesis: consistent double-digit returns averaging 19% annually with zero monthly losses—an extraordinarily attractive risk-adjusted profile in a competitive hedge fund marketplace. The fund's apparent performance attracted investors globally, including Jens Blomeyer, a German investor and entrepreneur, who committed $125,000 to the strategy. However, the fund's collapse in 2025 and the subsequent discovery of approximately $600 million in missing assets revealed that exceptional returns masked an underlying fraud scheme.
The investigation into Mars FX spans multiple jurisdictions and regulatory bodies, reflecting the global scope of investor exposure. US prosecutors in Manhattan, working alongside the FBI and a federal grand jury, have opened a criminal fraud inquiry. The matter has also been referred to the Securities and Exchange Commission, the Commodity Futures Trading Commission, and international civil regulators in the United Kingdom and the British Virgin Islands. According to documents reviewed by Bloomberg, the investigation is examining Mars FX, its sponsor Novus Capital Partners, and the circumstances precipitating the fund's collapse. Pending lawsuits in at least three nations allege forgery and money laundering, expanding the legal exposure beyond the primary fraud allegations.
The involvement of Deloitte, a tier-one auditing firm, has intensified accountability scrutiny. Deloitte faces litigation for signing off on Mars FX's financial statements prior to the 2025 collapse, raising questions about the quality of financial controls and audit procedures. Novus Capital Partners, the fund's sponsor, has attributed the collapse to a third-party technology company contracted by the firm, though culpability remains disputed. Novus stated it is attempting to recover missing assets, but the decentralized nature of the investigation and international complications have slowed recovery prospects.
The timing of this collapse coincides with a regulatory environment increasingly characterized by reduced oversight. This week, US regulators proposed eliminating filing requirements for smaller hedge funds while narrowing disclosure mandates for larger funds. Simultaneously, federal watchdogs face "sharp cutbacks in enforcement staff," according to the primary source, which observers note may substantially diminish prospects for recovering investor losses. Blomeyer's reflection on the incident—"Nobody understood the product, to be honest. We saw the returns, and we got blinded and greedy"—captures the dynamic that has historically enabled large frauds: investor attraction to exceptional returns combined with insufficient due diligence and regulatory vigilance.
