Share: This is an excerpt from Tuesday's (3/9) Point of Sale retail supply chain newsletter sponsored by ArcBest. Instacart had a crazy year. Capped off by last week's funding announcement of another $265 million at a valuation of $39 billion (more than 4x where it was to begin 2020), Instacart has seen every piece of its business explode over the past 12 months. By some accounts, the 8-year-old company now has roughly 50% of the online grocery market. With an IPO almost guaranteed this year, I wanted to look back at how Instacart has gone from niche to necessity and question whether it can maintain this dominant position in a highly competitive, highly sought-after market post-COVID.
