The price for design software developer Figma surged more than 250% on Thursday to close at over $117 per share after raising over $1.2 billion in an IPO, well over three times the $30-$32 range the company estimated in SEC filings earlier this week—making its 33-year-old CEO Dylan Field a billionaire.

Traders expressed confusion and frustration on Thursday as demand for Figma shares appeared to far exceed supply. Figma’s initial public offering this week was a boon for investors. Well, some investors.

Figma’s IPO valued the company above $19 billion on a fully diluted basis. It raised about $1.2 billion for the company and investors who cashed out on shares, making it the biggest venture-backed tech IPO since 2021, according to Renaissance Capital.
