Liquidity Challenges and VC Fundraising Decline Signal Caution

Despite the overall positive trajectory, concerning trends emerged around liquidity and fundraising. VC fundraising fell to its lowest total since 2019, with only $66 billion in capital raised, while the annual total of new funds dropped to 537—the lowest in at least a decade2
