Nearly one in three transactions that occur on U.S. B2B marketplaces take place on Amazon Business.

There is no getting around it. B2B marketplaces are the fastest-growing sales channel in B2B ecommerce, according to data in the forthcoming 2022 B2B Marketplace 400 report from Digital Commerce 360. And a big reason accounting for the rapid growth in online B2B marketplace sales is Amazon Business.

Bank of America Securities projects that in 2022, Amazon Business will post $41.5 billion in gross merchandise volume. That would be up 31.7% from a projected $31.5 billion in 2021. Amazon Business singlehandedly would account for 31.9% of all B2B marketplaces sales, or one in every three transactions, Digital Commerce 360 estimates based on these projections.

As soon as 2025, Amazon Business could post annual gross merchandise volume of about $83.1 billion, says BofA Securities.


“Amazon appears to have gotten over many of the B2B procurement system hurdles and has significantly grown its B2B reach over the past

two years,” BofA Securities analyst Justin Post said in a 2021 research note. “Amazon Business is a B2B marketplace that gives procurement professionals the selection, convenience, and value that they have become used to on Amazon’s core B2C marketplace.”

In 2022, Amazon will account for 31.7% of all B2B marketplaces sales of $130 billion, based on a projection from Digital Commerce 360.

Translation: Nearly one in three transactions that occur on U.S. B2B marketplaces take place on Amazon Business.
