FTX used random numbers to generate the size of its insurance fund

Quick Take

  • FTX displayed its insurance fund balance using a formula based on random numbers and daily trading volume rather than the actual amount of funds available.
  • Gary Wang, FTX’s cofounder, testified that the real insurance fund balance was lower than the amount displayed on the platform’s website.

The amount of money purportedly held in bankrupt crypto exchange FTX's insurance fund did not reflect reality, according to its co-founder Gary Wang. 

In statements made at the ongoing trial of Wang's former business partner Sam Bankman-Fried, Wang testified that the exchange used a random number — approximately 7,500— multiplied by the platform's daily volume and then divided by one billion to determine the amount of cash added to the fund. But that displayed number was not what was actually being stowed away. 

Wang, while testifying, confirmed that the displayed number did not match the real number in the database, and the real insurance fund balance was, in fact, lower than what was showcased to the public.

“Does that number have anything to do with the actual number in the insurance fund?” prosecutor Nicolas Roos asked.

Wang responded, "No."

Insurance funds are a safeguard to pay out profits and cover losses, preventing the automatic closure of profitable positions caused by widespread counterparty liquidations.
