SEC v. Mediatrix Capital Inc., et al. (2019)

Alleged — pending

These are allegations. SEC has filed an action; nothing in it has been proven, and the respondents have not been found liable. Everything described on this page is what the regulator alleges, not what a court has found. See our editorial policy.

Checked against the primary document on October 3, 2026. The library's summary, tags and figures for this record were compared with the regulator's own document by an AI model (Claude) following written instructions, with sampled and disputed records read a second time. No lawyer has reviewed them. A checked record can still contain errors, and checked does not mean endorsed. See how we check records or report a correction.

In September 2019 the SEC filed an emergency action in Colorado against Mediatrix Capital, three principals and further entities, alleging they put more than $125 million of investor funds at risk with a claimed algorithmic strategy that lost over $18 million in 2018 while over $35 million went to personal use. A court froze assets.

A dash means the release did not state a figure we could extract, not that the figure is zero. Penalty and disgorgement are stored separately so aggregates across the library do not double-count the same dollars.

What is alleged to have happened

The SEC announced the action on September 18, 2019 (LR-24600), filed September 12. It alleges false claims of an unbroken record and a 1,600% return, falsified statements and some Ponzi-like payments. The defendants are charged under Section 10(b), Section 17(a) and the registration provisions.

The Ponzi tag is removed because the release describes a trading-program offering fraud, with Ponzi-like payments mentioned in passing. The "et al." defendant is replaced by the four named defendants.
