U.S. grocery delivery company Instacart slashed its valuation by nearly 40per cent to about $24 billion, the company said on Thursday, citing recent market turbulence. The company, a pandemic darling as doorstep delivery boomed, was valued at $39 billion in a funding round in March last year, doubling its valuation in less than six months. "We are not immune to the market turbulence that has impacted leading technology companies - both public and private," said an Instacart spokesperson.
