Dive Brief:

• E-commerce newcomer Jet has swiftly gained market share, according to research from e-commerce solutions platform ChannelAdvisor. 

• Jet is the number four marketplace by GMV in marketplaces that ChannelAdvisor supports worldwide, and ChannelAdvisor says it could be number three after Amazon and eBay as early as next year.

• The average Jet seller GMV is twice that of GMV on Sears and Newegg, and its repeat buyer rate is 23%, beating eBay’s 17% and Amazon’s 11%, according to ChannelAdvisor's research.

Dive Insight:

ChannelAdvisor acknowledges that its sample size for this report is small, but the swift rise shown by Jet is compelling news. The proof will be in the long term — not just to see whether consumers will continue to try and stay with Jet, but also whether retailers on the marketplace will stick around.

Some merchants have balked at Jet’s low prices, which has contributed to some confusion over Jet’s online price comparisons, the result of agreements to not to undercut brands attempting to sell on other sites, including their own. 

The biggest challenge for Jet will be to maintain its business model in light of the fact that it is banking on membership fees alone to make its money. 

As ChannelAdvisor notes, it’s still early. But Jet appears to have some strong momentum on liftoff.
