FTX: the biggest collapse in crypto history — $8 billion missing and 25 years in prison

In November 2022, crypto exchange FTX — valued at $32 billion just months earlier — collapsed within days. Three years later, in June 2026, an appeals court finally rejected founder Sam Bankman-Fried's appeal — his 25-year prison sentence stands. It remains the biggest corporate collapse in crypto history. Here it is, by the facts, not the rumors.

What Happened

FTX was one of the world's largest crypto exchanges, and its founder Sam Bankman-Fried (SBF) was the industry's public face, regularly testifying before the US Congress. The collapse began when a leaked balance sheet of FTX-affiliated hedge fund Alameda Research showed that a huge share of its assets were FTX's own token, FTT, rather than independent holdings. That triggered a run on the exchange — and it turned out FTX physically couldn't return the money, because customer funds had secretly been funneled to Alameda and spent.

The Numbers

• Prosecutors found Bankman-Fried stole more than $8 billion in customer funds
• Defrauded FTX investors of more than $1.7 billion
• Defrauded Alameda Research lenders of more than $1.3 billion
• The court ordered $11 billion in forfeiture

At its peak, Bankman-Fried's personal net worth was estimated above $30 billion — it went to zero within days in November 2022.

The Trial and Sentence

In November 2023, a jury convicted Bankman-Fried on seven counts, including fraud, conspiracy and money laundering — three former FTX executives testified against him after striking plea deals. Under federal guidelines he faced up to 110 years; prosecutors sought 40-50 years, the defense argued for no more than 6.5. On March 28, 2024, Judge Lewis Kaplan handed down the sentence: 25 years in prison.

At the hearing, Bankman-Fried himself told the court: "I'm sorry about what happened at every stage. Things I should have done and said."

Why It's Back in the News

On June 12, 2026, a three-judge appeals panel rejected Bankman-Fried's appeal, calling the prosecution's evidence "conservatively stated, robust." That effectively closes the criminal case — every legal avenue for appeal has now been exhausted.

What This Means in Practice

The FTX case stands out precisely because there was no hack or technical exploit involved — just direct misappropriation of customer funds by the exchange's own leadership. The basic lesson: diversifying where you store funds (not keeping everything on one centralized platform) and knowing how to spot the structural red flags of a troubled project ahead of time — something we covered in detail in our breakdown of rug-pull warning signs — remains a working defense even against the largest, most reputable players in the market.
