Design-software company Figma’s stock rocketed 250% above its initial public offering price, and was headed for the largest ever first-day gain, after an IPO had raised more than $500 million.

Keep an eye on space tech company Firefly Aerospace, which is expected to go public the week of Aug. 4, as well as buy now/pay later firm Klarna and ticket marketplace StubHub, which have already filed to go public.

Figma’s stock was clearly in hot demand. The company initially said last week it expected to sell its stock to investors for $25 to $28 per share. On Monday, it upped that range to $30 to $32 a share before pricing its offering at $33 a share Wednesday .
