Would any of the traders mentioned that owe all that money to Interactive Broker's have to pay the total amount? Or is that part of Interactive Brokers' loss claim.

From the story:

> Customers will be made whole, Peterffy said. “We will rebate from our own funds to our customers who were locked in with a long position during the time the price was negative any losses they suffered below zero.”

I'd imagine this is so they don't get sued and have some shoddy code pop up during trial.

or they're raising capital and the end justifies the means

same result of avoiding litigation, but even fewer consequences
