Amusingly Thiel himself seems to have been out of SVB. He's being fingered[1] as the "cause" of the bank run and lots of people are asking if he shorted the stock.

[1] Somewhat unfairly. I mean, the guy's an outrageous jerk, but from the evidence at hand it genuinely looks like he recognized the problem with their balance sheet before everyone else, got himself out, and told his companies to do the same. And he was right. That's not fraud, that's good faith financial analysis.
