Worth noting that it actually opened at $150 on public markets. It's kind of funny how we call the $135 figure the "public offering" price when there is really nothing public about it. Maybe it made more sense in some past era when it was more difficult for third parties to make private pre-IPO investments.

Not that there's anything particularly unusual about this. High profile tech companies almost universally (actually I am not aware of any moderately recent exceptions at all) fall below the actual public opening price in the days or weeks following the IPO. I honestly don't know why anybody buys them.
