Klarna's November 2024 US IPO filing reports roughly $1 billion in revenue for 2023, against a last private valuation of $45.6 billion set in 2021 — the gap is the whole story.
Before a stock trades publicly, its price is negotiated by underwriters and institutional buyers, and most insiders are barred from selling for roughly 180 days — here's how each piece of the mechanism actually works, according to the SEC's investor-education arm.
The average IPO 'pops' 10-20 percent on day one, has for six decades, and not because bankers are careless — the discount is the price of a market that works on the first trade.
Klarna priced at $40 in September 2025, below its last private mark but above the skeptical case — and its F-1's story of cost discipline became the sector's textbook.
The IPO market is not a door but a window — open for quarters, closed for years, and the documented triggers are interest rates, comparables, and one deal everyone watches.
