It was a heavy week in crypto’s courtrooms, with fresh consequences for a fallen exchange’s executives, a closely watched prediction-market case and a nine-figure fraud indictment. Cointelegraph rounded up the developments, and together they show enforcement grinding forward on several fronts at once.
FTX executives hit with trading bans
On August 19, 2026, the US District Court for the Southern District of New York entered consent orders imposing trading and registration bans on two former FTX-Alameda executives, resolving a 2022 enforcement action by the Commodity Futures Trading Commission. Caroline Ellison, the former CEO of Alameda Research, received a five-year trading ban and a 10-year registration ban. FTX co-founder Zixiao “Gary” Wang received a five-year trading ban and an eight-year registration ban. CFTC enforcement director David Miller cited both executives’ “material assistance in the Commission’s FTX-related investigations.” The civil bans are separate from their criminal cases, in which Ellison was sentenced to two years in prison and Wang received time served.
Polymarket insider-trading case advances
A day later, on August 20, US prosecutors opposed a motion to dismiss charges against Gannon Ken Van Dyke, a US soldier accused of insider trading on prediction-market contracts. According to Cointelegraph, Van Dyke allegedly profited more than $400,000 using nonpublic information about the January 2026 removal of Venezuelan President Nicolás Maduro. Van Dyke had argued that the Commodity Exchange Act was too ambiguous to support the charges, but prosecutors rejected that reasoning. No court decision had been posted as of Friday.
A $165 million crypto Ponzi indictment
In the Northern District of Georgia, a 25-count indictment against Edward Zimbardi was unsealed on August 18, following an initial indictment on July 8, 2026. Prosecutors allege Zimbardi ran a $165 million cryptocurrency Ponzi scheme, tricking thousands of people into a so-called “Crypto Program” with false promises of enormous returns between 2022 and 2023. The charges include 12 counts of wire fraud, one count of money-laundering conspiracy and 11 counts of transactional money laundering, with Magistrate Judge Anna Howard overseeing early proceedings. Cointelegraph reports that seized assets include 11.87 BTC, 2.15 ETH and more than 713 million SHIB tokens, together valued at roughly $6 million.
Taken together, the week underscores how the legal aftermath of crypto’s excesses is still unfolding. Years-old collapses are producing new penalties, novel venues like prediction markets are testing the reach of existing commodities law, and old-fashioned fraud dressed up in tokens keeps landing in federal court. For an industry eager to move past its scandals, the docket is a reminder that accountability tends to arrive on its own schedule.
