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

Same yardstick, side by side (as of October 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 ROKU 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 ROKU 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, with quarterly sales of $42.2 billion in the June 2026 quarter (an annual run rate of roughly $170 billion) 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), at $19.8 billion in the June 2026 quarter alone.

Roku operates the leading streaming operating system in the United States, powering both its own streaming devices and smart TVs manufactured by third-party OEM partners who license the Roku OS. Its platform connects viewers to thousands of streaming channels and earns revenue primarily through advertising sold across the platform, a share of subscription fees when consumers sign up for services such as Netflix or Hulu through Roku, and sales of streaming hardware devices sold near or below cost to grow the installed base. The Roku Channel, the company's own free ad-supported streaming service, has grown to represent more than 6% of all U.S. TV streaming time according to Nielsen, and the company also owns the Howdy subscription service launched in 2025. Roku was founded in 2002 by Anthony Wood, an electrical engineer and serial entrepreneur who previously founded ReplayTV, one of the first digital video recorder companies, and briefly served as VP of Internet TV at Netflix. Wood's team initially developed the first Netflix-streaming set-top box as a project for Netflix; when Netflix decided not to release a proprietary device, Roku inherited the technology and launched independently in 2008. The company went public on Nasdaq in 2017 and is headquartered in San Jose, California. Wood continues to serve as founder, chairman, and CEO, with Dan Jedda serving as CFO and COO.

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.
• ROKU drivers: The Fox merger now sets the price; Structural shift in TV advertising.

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 ROKU, roku derives the majority of its platform revenue from digital advertising, making earnings highly sensitive to macroeconomic cycles and swings in advertiser budgets.

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; ROKU 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 ROKU guides.

AMZN. Amazon's trailing P/E fell to about 20x by October 2026, but mostly because one-time gains on its Anthropic stake swelled net income, not because the stock got cheaper; on forward estimates it trades near 24x, still well below the ~40x of early 2026. The valuation premium is paid for AWS and advertising; retail is essentially valued near cost. The open question is whether AWS growth near 37% justifies capex that has pushed free cash flow below zero, and the October 29 report is the next read on that.

ROKU. Standalone multiples have compressed as earnings caught up: the trailing P/E has fallen from roughly 103x in late June to ~66x, and the forward P/E from ~52x to ~39x, as Q2 2026 EPS of $1.20 beat the ~$0.56 estimate. Those multiples matter less than usual, though, because the stock now trades against the Fox merger terms ($96.00 in cash plus 0.9693 of a share of Fox Class A common stock per share) rather than against peers. The practical valuation question is the spread between ROKU's price and the current value of that cash-and-stock package, which reflects time to close and regulatory risk. Analysts expect ~$2.99 of 2026 EPS on ~$5.63 billion of revenue, and the 20 analysts tracked carry a hold consensus with a mean target near $162.

Headline figures (approximate, October 2026): AMZN shows revenue (ttm) ~$776 billion (June 2026 quarter up ~20% YoY), operating margin ~13.7% (AWS materially higher; retail much lower), net income (ttm) ~$135 billion (includes large Anthropic investment gains), eps (ttm) ~$12.43; ROKU shows deal consideration (fox merger) $96.00 cash + 0.9693 Fox Class A share per ROKU share, revenue (ttm) ~$5.21 billion (Q2 2026 up ~22% year over year), net income (ttm) ~$355 million (Q2 2026 ~$164 million), free cash flow (ttm) ~$837 million.

AMZN and ROKU 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.
