SEC v. Nicolo Nourafchan and others (insider trading, 2026)

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.

In May 2026 the Securities and Exchange Commission charged 21 individuals in an alleged insider trading scheme using information misappropriated from several global law firms, orchestrated, it says, by M&A attorney Nicolo Nourafchan and Robert Yadgarov between 2018 and 2024. The complaint alleges Nourafchan took information on at least a dozen deals and passed it on, directly or through Yadgarov, to people who kicked back profits or tipped others, and that they recruited another corporate lawyer. It seeks injunctions, disgorgement and penalties; criminal charges were announced against all defendants.

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 Securities and Exchange Commission announced this matter on May 7, 2026 as release LR-26551, filing in the District of Massachusetts on May 6, 2026.

The release names only Nourafchan and Yadgarov among the 21 defendants, so only those two are recorded here. The release reports no outcome.

For the regulator's own account of the facts, read the primary document linked above. This page deliberately summarises the structured record rather than reproducing the release.

Checked on 2026-10-04: no outcome found on SEC pages. The SEC litigation-release index, which runs through LR-26664, has no later release naming these defendants.
