This is tragic.

The consensus I've gathered is that this was a result of a stock option credit spread's short leg being assigned combined with a misunderstanding of the trading platform's reporting. If this is true, an analogy for the situation would be:

The individual bet on a coin flip, wagering $10 (representing the $700k) on heads and $9 (figurative amount representing the spread) on tails.

The outcome was tails.

The account immediately reflected the loss but not the win, displaying a -$10 balance.

When the $9 payout from the win would have settled, the account balance would have become -$1 instead of -$10.

The individual didn't realize the $9 payout was coming, and took his life in reaction to the -$10 balance.

How do you know this?

Hard to be completely sure without RH or the family specifying, but browsing r/WSB’s thread on the incident, looks like a lot of people have encountered this exact same issue and had it clear up the next day

It's a known RH bug
