AMZN vs CPNG: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: AMZN is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. AMZN and CPNG share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined AMZN and CPNG exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

Amazon is one of the largest companies in the world, operating across three major business lines. Amazon Web Services (AWS) is the dominant global cloud computing provider, generating around $110 billion in annual revenue and most of the company's operating income. The North America and International e-commerce segments include the Amazon online marketplace, Prime membership, and third-party seller services. Advertising has grown into the third-largest digital ad business in the world (after Google and Meta).

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• AMZN drivers: AWS as the AI infrastructure backbone; Retail margin expansion.
• CPNG drivers: Product Commerce as the profit engine; Taiwan and international expansion.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Hyperscaler AI capex is concentrated; if model training demand cools, AWS growth slows. For CPNG, the main tension is that Coupang's growth bets in Taiwan, Eats, Play, fintech, and Farfetch lose money while it invests, so overall profitability depends on the profitable Product Commerce core outpacing those losses.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick AMZN if you believe its drivers more; CPNG if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the AMZN and CPNG guides.

AMZN. Amazon's headline P/E reflects the aggregate of low-margin retail and high-margin AWS/advertising. The valuation premium is paid for AWS specifically; retail is essentially valued near cost. P/E of 40x is elevated versus the S&P 500 average (~22x), supported by AWS growth re-accelerating.

CPNG. Figures are approximate and tied to the asOf date; verify live numbers before acting. Coupang is valued largely on revenue growth and the trajectory of its segment margins rather than a simple trailing multiple, because reported profitability is depressed by deliberate investment in Developing Offerings and international expansion. Investors typically watch Product Commerce margins, the losses in Developing Offerings, active-customer and spend trends, and currency effects more than any single earnings ratio.

Headline figures (approximate, early 2026): AMZN shows revenue (ttm) ~$650 billion, operating margin ~10% (AWS materially higher; retail much lower), net income (ttm) ~$60 billion, eps (ttm) ~$5.50; CPNG shows revenue (fy2025) about $34.5 billion, up roughly 14% year over year, q1 2026 revenue about $8.5 billion, up roughly 8% year over year, segment profitability Product Commerce profitable with solid EBITDA margins; Developing Offerings operating at a loss as it invests, taiwan revenue growing triple digits year over year on a rapid last-mile logistics build-out.

AMZN and CPNG are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
