A fabricated $359 million brokerage account behind a $17 million loan-fee scheme

2025 United States Sentenced

Carlos Manuel da Silva Santos, a Portuguese national and founder/CEO of San Diego-based Ethos Asset Management, Inc., ran an advance-fee loan scheme that collected upfront fees calculated as a percentage of requested loan amounts, then used falsified financial documents, including a brokerage account claimed to hold $359,088,190.22 that did not exist, to convince victims the loans were coming. One victim alone was induced to pay more than $8 million. Arrested in November 2023, Santos pleaded guilty in January 2025 to wire fraud conspiracy and aggravated identity theft, and was sentenced in May 2025 to 87 months in federal prison.

The facts, as recorded

Why this case matters

This is the largest documented loss on this page, and the most elaborate in its use of fabricated financial proof. A single fake brokerage-account figure, stated to nine decimal-adjacent precision, $359,088,190.22, was specific enough to survive a victim’s scrutiny long enough to extract more than $8 million from that person alone.

A Ponzi structure inside a loan-fee scheme

Santos did not simply pocket each fee. Prosecutors describe using new victims’ payments to reimburse earlier ones, the same rolling-repayment mechanic used to keep a Ponzi scheme’s complaints quiet, layered on top of a loan-fee pretext rather than an investment one.

Falsified numbers as the core product

Inflating Ethos’s balance sheets and bank statements by more than $100 million in some instances was not an incidental exaggeration; it was the mechanism that made a nonexistent lender look real enough to extract seven- and eight-figure payments from sophisticated borrowers who would otherwise have asked for proof of funds.

The caveat

Santos pleaded guilty and has been sentenced; that part of the case is final as of this page’s last review. Restitution had not yet been set at the time of sentencing, per the source above, so the actual amount victims recover is not yet known. Any other individuals described in source reporting as co-conspirators are not named here because their own legal outcomes were not confirmed in the sources above.
