Costco is set to open its first-ever standalone 40-pump gas station this June in Mission Viejo, California, with a second location planned for Honolulu in 2027. The move signals that Costco is doubling down on fuel as a standalone membership draw, separate from its warehouse footprint.

The timing couldn’t be more relevant. As we noted in our recent report, higher fuel prices have accelerated a shift towards value-driven fuel destinations. 

Costco’s share of total U.S. gas station spend rose to 6.7% in the week ended March 8. In the week ending March 15, Costco’s share climbed further to 6.9%, for a total gain of 50 basis points over two weeks. Sam’s Club has shown equally compelling momentum, climbing 20 basis points over the same two-week period to 2.6% — a meaningful gain that underscores warehouse clubs broadly, not just Costco, are emerging as the go-to destination for cost-conscious drivers.
