However they’re coming into 2026 with very totally different valuation multiples — and really totally different underlying enterprise development too. Surprisingly, nonetheless, the inventory with the cheaper valuation is the one with meaningfully quicker income development.
Additional, this can be a notably fascinating time to match the 2 shares, as their year-to-date returns have diverged. Amazon inventory has pulled again about 14% during the last month as buyers digest an enormous new capital spending plan.

Amazon’s fourth-quarter outcomes, introduced on Feb. 5, confirmed a enterprise with severe momentum. Complete internet gross sales through the interval rose 14% 12 months over 12 months to $213.4 billion, accelerating from 13% development within the prior quarter.
Beneath the floor, nonetheless, Amazon’s growth-driving cloud computing enterprise, Amazon Internet Providers (AWS), noticed an much more vital acceleration than its consolidated enterprise. Income within the cloud phase rose 24% 12 months over 12 months to $35.6 billion. That tempo edged up from the earlier quarter, signaling that the optimization headwinds (when corporations scrutinize their cloud spending to get extra bang for his or her buck) of the final two years have abated.
Moreover, Amazon’s fourth-quarter working earnings rose from $21.2 billion within the year-ago interval to $25 billion this quarter.
Trying forward, nonetheless, Amazon’s working earnings will probably be challenged within the close to time period, as administration is planning a significant funding cycle.
Particularly, Amazon expects to take a position about $200 billion in capital expenditures in 2026 — up sharply from the $131.8 billion it spent in 2025. This comes because the AI growth is inflicting a surge in demand for cloud computing.
“Prospects actually need AWS for core and AI workloads,” stated Amazon CEO Andy Jassy through the firm’s fourth-quarter earnings name. “And we’re monetizing capability as quick as we are able to set up it.”
This large build-out for AI infrastructure will strain free money movement within the close to time period. Nevertheless it additionally highlights the size of the demand Amazon is seeing.
Costco is rising at a a lot slower price, however its enterprise should not be underestimated.
In its fiscal first quarter of 2026, which ended Nov. 23, the membership-based retailer’s internet gross sales elevated 8.2% 12 months over 12 months to about $66 billion. Comparable gross sales, a metric the corporate defines as gross sales at warehouses open no less than a 12 months, rose 5.9% within the U.S., excluding the impacts of gasoline costs and international alternate. And comparable gross sales, adjusted for a similar results, rose 6.4% when together with its Canada and “different worldwide” segments, alongside its U.S. enterprise.
After all, the core of Costco’s mannequin is its membership charge, which flows virtually completely to the underside line. Membership charge income jumped 14% 12 months over 12 months to $1.33 billion. Impressively, Costco maintained a 92.2% renewal price within the U.S. and Canada, even after implementing a membership charge enhance in late 2024.
However at about 54 occasions earnings, the market is pricing in near-perfect execution for years to come back. That top valuation, which displays the sturdiness and predictability buyers see in Costco’s enterprise, leaves little room for error if shopper spending slows or membership development cools.
So, which is the higher purchase?
Finally, each corporations have large structural benefits. Costco has unmatched scale and buyer loyalty, whereas Amazon has a dominant logistics community and the main cloud computing platform.
The deciding issue is valuation. Amazon trades at about 29 occasions earnings. For a corporation rising its high-margin promoting income by 22% and its cloud income by 24%, that worth is compelling.
The danger is that Amazon’s aggressive AI spending doesn’t ship the anticipated returns, pressuring margins for longer than anticipated. However at 29 occasions earnings, the inventory is arguably already pricing in that threat. And if these investments repay, in the present day’s worth might seem like a discount in hindsight.
I might anticipate a greater entry level on Costco inventory. However I feel Amazon inventory is a purchase on this dip.
