It was an abrupt fall from grace for a company that was once a darling of the crypto industry. FTX raised $400 million from investors in January, valuing the company at $32 billion. It attracted money from investors such as Singapore state investor Temasek and the Ontario Teachers' Pension Plan as well as celebrities and sports stars.
Bankman-Fried, 30, known for his trademark shorts and t-shirt attire, has morphed from being the poster child of crypto's successes to the protagonist of the industry's highest-profile crash.
"The shock was that this guy was the face of the crypto industry and it turned out that the emperor had no clothes," said Thomas Hayes, managing member at Great Hill Capital LLC in New York.
The week's turmoil hit already-struggling cryptocurrency markets, sending bitcoin to two-year lows . Bitcoin dropped after FTX's announcement and was down 4.3% at $16,803 on Friday afternoon.
Shares of cryptocurrency and blockchain-related firms also dropped on the news.
FTX's token FTT plunged 30% on Friday to $2.57, facing an 88% weekly loss.
Bankman-Fried, whose net worth was estimated as high as $26.5 billion by Forbes a year ago, repeatedly apologized.
"I'm really sorry, again, that we ended up here," he said in a series of tweets.
Possible contagion effect
In its bankruptcy petition, FTX Trading said it has $10 billion to $50 billion in assets, $10 billion to $50 billion in liabilities, and more than 100,000 creditors. John J. Ray III, a restructuring expert, has been appointed to take over as CEO.
