Boston DOJ Charges 30 in Decade-Long BigLaw Insider Trading Scheme
Federal prosecutors unsealed a sweeping insider trading indictment on May 21, 2026, charging 30 people with operating a decade-long scheme to steal confidential merger-and-acquisition information from major law firms and trade on it for tens of millions in illicit profits. The DOJ and FBI allege the network extracted nonpublic deal details from premier BigLaw firms, then funneled tips through layers of traders and intermediaries to obscure the source and capitalize on expected market movements. The indictment names former BigLaw attorney Nicolo Nourafchan and New York lawyer Robert Yadgarov as key recruiters and facilitators who allegedly channeled information and moved money through shell companies, foreign accounts, and cash payments. Nineteen defendants were arrested; two others located in Russia and Israel remain fugitives. The indictment references unnamed co-conspirators still working at BigLaw firms as of this year.
