Do Kwon, the co-founder of Terraform Labs, was sentenced on December 11, 2025 to 15 years in federal prison by Judge Paul Engelmayer in the Southern District of New York.1United States Department of Justice. Crypto-Enabled Fraudster Sentenced for Orchestrating $40 Billion Fraud The Do Kwon sentence closes the U.S. criminal case tied to the May 2022 collapse of the TerraUSD stablecoin and its companion token Luna, an implosion that wiped out roughly $40 billion in market value.
What Kwon Pleaded Guilty To
A federal grand jury in Manhattan had returned a nine-count superseding indictment covering conspiracy, commodities fraud, securities fraud, wire fraud, and money laundering conspiracy.2United States Department of Justice. United States v. Do Hyeong Kwon – Superseding Indictment Kwon did not go to trial on all of it. In August 2025, he pleaded guilty to two counts: one count of conspiracy to commit securities fraud, commodities fraud, and wire fraud, and one substantive count of wire fraud.3United States Department of Justice. Do Kwon Pleads Guilty to Fraud The other seven counts were resolved through the plea agreement.
The Financial Penalties
As part of the plea, Kwon agreed to forfeit more than $19 million in fraud proceeds, including his interest in Terraform Labs.3United States Department of Justice. Do Kwon Pleads Guilty to Fraud That forfeiture sits alongside a much larger civil judgment from a parallel Securities and Exchange Commission case.
In April 2024, a Manhattan jury unanimously found Kwon and Terraform Labs liable for securities fraud after less than two hours of deliberation. The resulting settlement obligated Kwon and Terraform to pay more than $4.5 billion combined. Kwon’s personal share came to just over $204 million: $110 million in disgorgement and $14.3 million in prejudgment interest, both joint and several with Terraform Labs, plus an $80 million civil penalty.4U.S. Securities and Exchange Commission.

The Conduct Behind the Sentence
Two schemes drove the criminal case.
The Secret May 2021 Bailout
UST was designed to hold its one-dollar peg through an algorithmic mechanism. In May 2021, that mechanism failed publicly for the first time. UST dropped below 92 cents and Luna lost roughly 75% of its peak value in a matter of days.2United States Department of Justice. United States v. Do Hyeong Kwon – Superseding Indictment The algorithm could absorb only about $20 million in redemptions before arbitrage stopped working.
Kwon secretly negotiated an oral agreement with an outside trading firm to spend up to $100 million buying UST and Luna to push the price back to a dollar. In exchange, he accelerated delivery of Luna tokens under existing investment agreements. Then he told the public the algorithm had restored the peg on its own. In an October 2021 YouTube interview, Kwon specifically denied that Terraform had any contractual relationship with market makers stabilizing UST. Prosecutors called that statement “knowingly false and misleading.”2United States Department of Justice. United States v. Do Hyeong Kwon – Superseding Indictment Investors kept buying in on a track record the algorithm had never actually earned. When UST lost its peg again in May 2022, no bailout came.
The Chai Payment App
Kwon repeatedly told investors that Chai, a popular Korean mobile payment app, ran its commercial transactions through the Terra blockchain. It did not. Chai processed payments through traditional methods, moving Korean won between customers and merchants with no blockchain involvement.5U.S. Securities and Exchange Commission. Terraform Labs Pte. Ltd. Amended Complaint To create the appearance of blockchain activity, Terraform programmed an internal server that replicated completed Chai transactions on the Terra blockchain after the fact. Chai itself told its own investors in emails that it did not use blockchain to process payments and that Korean law would not have permitted it.
What Comes After the U.S. Sentence
Kwon’s legal exposure does not end at 15 years. South Korea issued its own arrest warrant in September 2022, charging him with fraud and violations of the country’s capital markets law. Kwon is expected to face prosecution in South Korea after completing his U.S. sentence. The Montenegrin decision that sent him to the United States rather than Seoul specifically weighed the possibility of a subsequent extradition, and the U.S. plea agreement reportedly contemplates an eventual transfer to South Korean authorities. Financial crimes in South Korea can carry lengthy prison terms.
What Victims Can Actually Recover
If you lost money in the Terra collapse, the practical recovery channel is the Terraform Labs bankruptcy rather than the headline $4.5 billion SEC judgment. Terraform filed for Chapter 11 in the District of Delaware on January 21, 2024, and an affiliate followed in July 2024.6Epiq. Terraform Labs Pte. Ltd.

Investors who missed the court-imposed bar date for filing a claim may be permanently barred from any distribution.6Epiq. Terraform Labs Pte. Ltd. Overview Case The $4.5 billion figure from the SEC case is largely paper; what creditors receive depends on Terraform’s actual remaining assets, which are a small fraction of that amount.
