Jan 14 (Reuters) - Venture capital dealmaking in the United States reached an all-time high in 2021 at nearly $330 billion, buoyed by excess liquidity and an accommodative monetary policy, according to a report from PitchBook and the National Venture Capital Association. Venture capital firms ramped up bets on technology, biotech, healthcare and fintech sectors, announcing a record 17,054 deals in the year. It was also the best year on record for VC fundraising, which hit $128.3 billion across 730 funds. The figure, which breached the $100 billion-mark for the first time, was $40 billion higher than the previous record in 2020.

The frenetic pace of fund raising is expected to continue this year, as cash with venture capital firms remains at an all-time high, and returns outpace all other assets classes, the report added. VC-backed companies going public or being bought out led to exits worth $774.1 billion in 2021, nearly 88% of which was realized through public listings. While the U.S. initial public offering (IPO) market continued on a tear, special purpose acquisition companies have offered a viable alternative to IPOs despite tightening regulatory scrutiny.
