ALT5 Sigma, a cryptocurrency firm that recently partnered with Donald Trump’s World Liberty Financial (WLF), has forcefully denied reports that one of its executives is under investigation by the U.S. SEC. Earlier this week, rumors emerged claiming that venture capitalist Jon Isaac was under investigation for insider trading and manipulating earnings related to ALT5’s $1.5 billion treasury deal with WLF. Both the company and Isaac have rejected the claims, calling them factually inaccurate.
Company and Executive Push Back
In a statement shared on X, ALT5 Sigma made it clear that Isaac is not its current or past president or adviser, and it has no knowledge of any SEC investigation regarding its operations. Isaac echoed this stance, stating he is not the company’s president and is not facing any regulatory probe. He acknowledged being a shareholder, holding over one million ALT5 shares, and expressed continued support for the firm.
ALT5 Sigma has been made aware of reports in the press and on social media. For the record: Jon Isaac is not –– and never was –– the President of ALT5 Sigma and he is not an advisor to the company. The company has no knowledge of any current investigation regarding its activities…

Market Fallout from the Allegations
The initial report, published by The Information, triggered a sharp market reaction. ALT5’s share price fell 10.5% to $10.48 before sliding further in after-hours trading to $5.39, below pre-announcement levels for the WLF treasury deal. The sell-off underscored investor sensitivity to regulatory rumors, particularly in a sector still grappling with trust issues.
SEC Filings Reveal Consulting Role
While both parties deny the investigation, SEC filings from December show that Isaac entered into a two-year consulting agreement with ALT5 in March 2024. His responsibilities involved providing guidance on growth strategies, financial restructuring, and acquiring clients, along with weekly update calls to management. The documents also outline his conversion of a $540,000 promissory note, including interest, into 465,753 ALT5 shares in late 2024.
Past Regulatory History
The issue is complicated by Isaac’s past with the SEC. In 2021, the agency filed a civil lawsuit against him and his businesses, Live Ventures and JanOne, claiming financial and disclosure fraud. This case is still ongoing in federal court, and Isaac has denied any wrongdoing. For now, ALT5 Sigma’s leadership is working to contain the fallout, framing the latest claims as misinformation amid heightened scrutiny of Trump-linked crypto ventures.
