Ponzi schemes survive on two things: the appearance of performance and the prevention of doubt. Sudheesh Nambiar, a 39-year-old resident of Milpitas, California, managed both for nearly six years by posting fabricated trade results to a dedicated Telegram chatroom, sending investors doctored account statements showing profitable returns, and using new investor money to pay the investors who came before them. Operating under the name Spartan Trading, Nambiar raised approximately $43 million from more than 400 investors across the United States between November 2018 and May 2024, targeting primarily the Indian American community across the San Francisco Bay Area through personal connections and Telegram. The SEC filed a civil complaint against him on April 15, 2026, in the Northern District of California, alleging fraud, unregistered securities offerings, and investment adviser violations over more than five years. Nambiar remains in Milpitas as of April 2026. No criminal charges have been filed.
How Nambiar Built a Trusted Investor Community Before Systematically Draining It
The investor base Nambiar assembled was not random. He recruited through personal relationships inside the Indian American community, then used Telegram to manage and expand that network at scale. He promised to pool investor funds and trade securities with them, offering annual returns of 20 to 40 percent and splitting profits on a 70-30 basis, with investors receiving the larger share. The structure mimicked a legitimate pooled investment operation closely enough that it held up for years.
Nambiar created a dedicated Telegram chatroom for investors and posted daily updates purporting to document trading activity and gains. When investors responded with praise, that praise circulated within the same chatroom, reinforcing the perception of success for every other member who read it. He also sent fabricated account statements, Excel spreadsheets, and charts that appeared to document a near-perfect trading record. None of it reflected actual performance. In reality, Nambiar was a consistently losing trader who accumulated approximately $21 million in trading losses over the course of the scheme. The documents investors received bore no relationship to what was happening in his accounts.
The $18 Million in Ponzi Payments and $8 Million in Loans That Kept the Scheme Alive
Sustaining a losing trading operation for nearly six years requires constant cash. Nambiar drew from two sources. He routed new investor deposits to make payments to earlier investors, totaling approximately $18 million in Ponzi-like payments over the life of the scheme, maintaining the illusion that Spartan Trading generated real returns. When that was not enough, he borrowed roughly $8 million in high-interest loans from cash advance companies and funneled that money into the same payment cycle.
Nambiar also used investor funds for personal expenses. Hotel and resort stays, student loan payments, and private school tuition were among the personal costs he covered with money investors believed was being actively traded. By March 2024, he cut off all investors’ ability to post in the Telegram chatroom and went silent with many of them. Two months later, when investors began demanding withdrawals he could not fund, the scheme collapsed. Many lost everything they had committed to Spartan Trading.
A Second Fund That Collapsed to $982 Within Two Years of Launch
While Spartan Trading was still running, Nambiar launched a separate vehicle. Between late 2020 and April 2021, he raised approximately $900,000 from nine investors through a private fund called Spartan Trading Capital Fund, LP. He did not disclose to those nine investors that his trading record was fabricated, that Spartan Trading was a Ponzi-like operation, or that the fund they were joining was built on the same failing foundation he had constructed for his broader investor base.
The fund collapsed within months of launch. By March 2023, its gross asset value had fallen to $982 on $900,000 in invested capital, a loss of effectively everything. The fund’s destruction is significant beyond the nine investors it cost. It demonstrates that Nambiar’s conduct extended beyond informal trading arrangements with community contacts into formally structured investment vehicles, solicited without material disclosures, that he knew were likely to fail.
The Community Forum Posts That Surfaced Investor Alarm Long Before the SEC Acted
Long before the SEC filed its complaint, members of online communities serving Telugu-speaking Indians were raising questions about Nambiar and Spartan Trading. Forum posts as early as February 2025 described investors unable to reach him, asking whether others had experienced the same silence. One post described him as having collected $30 million in total before going dark. The community that trusted him most was the community left most exposed when the scheme ended.
The SEC’s investigation was conducted by Yoona Kim, Hannah Cho, and Mitchell Davidson of the San Francisco Regional Office, supervised by Rahul Kolhatkar, David Zhou, and Jason Lee. Litigation is led by Jason Bussey and Audrey Pak. The complaint charges Nambiar with violating the registration and antifraud provisions of the Securities Act of 1933, Section 10(b) of the Securities Exchange Act of 1934, and the investment adviser fraud provisions of the Investment Advisers Act of 1940. The SEC seeks permanent injunctions, disgorgement with prejudgment interest, and civil monetary penalties.
Conclusion
Nambiar’s scheme ran for more than five years not because it was sophisticated but because the tools he used were effective. Fabricated statements, daily Telegram updates, and community trust together kept 400 investors from asking the right questions. The money was being lost, borrowed against, and recycled back to earlier investors in smaller amounts while the Telegram chatroom filled with praise. The SEC filed its complaint on April 15, 2026. Nambiar remains in Milpitas. The investors who posted in community forums asking where their money went are still waiting for an answer.
