Record highs in the stock market have facilitated a boom in new company listings this year, with a record 2,388 firms going public around the globe, according to data from Ernst and Young.

Helping drive a resurgence in new company listings were SPACs, which peaked in early 2021 after a surge last year. Altogether, companies have raised $453 billion in proceeds from their IPOs, representing a 67% increase relative to 2020 and a more than doubling from 2019 levels.

Firms going public have predominately been in the technology sector, and the Nasdaq Exchange captured the most IPOs relative to other global stock exchanges. High profile IPOs this year include electric vehicle startups Rivian and Lucid Group, and direct-to-consumer brands Allbirds and Warby Parker.

And with more than 900 IPOs this year on US exchanges alone, there have been plenty of big winners and losers.

These are the 10 best performing US IPOs of 2021 of companies with at least a $1 billion market capitalization. All performance data is as of December 15 and was sourced from Koyfin.
