As Recode reported Tuesday, PetSmart is acquiring online pet store Chewy for $3.35 billion — the biggest e-commerce acquisition of all time.
For context, this is an even bigger deal than Walmart’s acquisition of online retailer Jet.com last year — which was then the biggest e-commerce acquisition to date. These companies are using e-commerce acquisitions to improve their online retail prospects.
Here’s a list of the biggest e-commerce mergers, acquisitions and buyouts of all time, by deal size, according to data from research firm PitchBook.
Update: The chart is focused on acquisitions of private startups and does not include deals involving public companies, such as Zulily.
