COST vs SBUX: How Costco Wholesale and Starbucks Corporation Compare (2026)
Last updated July 2026
Short answer
COST is the larger of the two ($430.88B market cap): the incumbent the market prices for continued execution (42.90x forward earnings, beta 0.87). SBUX is the smaller challenger ($118.36B), cheaper on forward earnings (34.47x): more room to run, but more to prove. The real question is which set of drivers you believe, and whether owning one (or both) leaves you over-concentrated.
COST vs SBUX: the tie-breaker metrics
Same yardstick, side by side (as of July 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.
| Metric | COST | SBUX | What it tells you |
|---|---|---|---|
| Market cap | $430.88B | $118.36B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 42.90 | 34.47 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Trailing P/E | 48.80 | 79.27 | Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price. |
| Beta | 0.87 | 0.97 | Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through. |
| Price vs 52-week range | 51% of range | 83% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
Reading it: SBUX 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.
Before you buy: how COST and SBUX affect your concentration
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. COST and SBUX 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 COST and SBUX 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.

What does Costco Wholesale (COST) do?
Costco Wholesale operates a membership-based warehouse club chain. Members pay an annual fee (currently $65 for basic Gold Star, $130 for Executive) for access to Costco warehouses, where they can buy products at lower markups than traditional retailers. Costco operates approximately 900 warehouses globally, with the largest concentration in the United States plus meaningful presence in Canada, Mexico, the UK, Japan, South Korea, Taiwan, Australia, and other markets.
What does Starbucks Corporation (SBUX) do?
Starbucks Corporation (Nasdaq: SBUX) is the world's largest specialty coffee retailer, roaster, and marketer. The company operates through three segments: North America, International, and Channel Development. Its roughly 41,000 stores worldwide sell coffee and tea beverages, whole-bean and ground coffees, ready-to-drink products, and food items including pastries and sandwiches. Revenue flows primarily from company-operated stores, with additional streams from licensed store royalties, packaged consumer goods sold through grocery and foodservice channels, and its Global Coffee Alliance partnership. The loyalty ecosystem, Starbucks Rewards, anchors the digital channel and generates recurring, data-rich customer engagement.
COST vs SBUX: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- COST drivers: Membership fee growth; International expansion.
- SBUX drivers: Turnaround Gaining Momentum; Loyalty and Digital Flywheel.
Which fits which kind of investor
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: Costco's premium valuation embeds high expectations for continued same-store sales growth and margin expansion. For SBUX, the valuation is the most prominent near-term risk: at roughly 72x trailing earnings (as of late March 2026), the stock prices in a near-perfect turnaround, leaving very little cushion if comparable-sales growth stalls or margins recover more slowly than expected.
COST or SBUX: which should you pick?
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 COST if you believe its drivers more; SBUX 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 COST and SBUX guides.
COST vs SBUX: the full fundamentals
COST. Costco trades at one of the highest P/E ratios in retail, reflecting the durable membership model, consistent same-store sales growth, and the long runway for international expansion. The premium is also driven by Costco being widely viewed as a quality compounder in retail. The valuation has compressed historically only during severe market drawdowns.
SBUX. Starbucks' fiscal 2025 financials reflect a deliberate investment cycle: revenue grew about 2.8% but net income fell roughly 50% year over year as the company absorbed restructuring costs, higher labor hours, and store closures to fund the turnaround. The operating margin compression from roughly 14.9% to 7.9% is broadly expected to be partly cyclical, with analysts projecting a rebound as volume leverage and operational efficiency improvements take hold. At roughly 72x trailing earnings, the stock trades well above both its own 10-year historical average of around 38x and the broader U.S. hospitality industry average near 20x, reflecting a premium for turnaround optionality.
Headline figures (approximate, early 2026): COST shows revenue (ttm) ~$260 billion, operating margin ~3.5% (low, by design; membership fees are the profit lever), net income (ttm) ~$7.5 billion, eps (ttm) ~$17.00; SBUX shows revenue (fy2025) ~$37.2 billion, revenue (ttm through march 2026) ~$38.5 billion, net income (fy2025) ~$1.9 billion, operating margin (fy2025) ~7.9%.
The bottom line: COST vs SBUX
COST and SBUX 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. Walnut can show your combined COST and SBUX exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between COST and SBUX?
+
Costco Wholesale operates a membership-based warehouse club chain. Starbucks Corporation (Nasdaq: SBUX) is the world's largest specialty coffee retailer, roaster, and marketer. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is COST or SBUX the better stock?
+
Neither is universally better. COST is the larger incumbent; SBUX is the smaller challenger and looks cheaper on forward earnings. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, COST or SBUX?
+
On forward P/E (as of July 2026), COST trades at 42.90x and SBUX at 34.47x, so SBUX is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both COST and SBUX?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of COST vs SBUX?
+
COST: Costco's premium valuation embeds high expectations for continued same-store sales growth and margin expansion. Any consumer slowdown or competitive pressure from BJ's, Sam's Club, or Amazon would compress the multiple. SBUX: The valuation is the most prominent near-term risk: at roughly 72x trailing earnings (as of late March 2026), the stock prices in a near-perfect turnaround, leaving very little cushion if comparable-sales growth stalls or margins recover more slowly than expected. The consumer environment poses a macro headwind, with CEO Niccol himself flagging rising uncertainty in mid-2026 even as near-term results held. Competition from Luckin Coffee in China (with approximately 26,200 stores) and domestic value-oriented rivals like Dutch Bros continues to intensify. Additionally, a roughly $14.6 billion long-term debt load and ongoing labor cost pressures from union-related investments limit financial flexibility.
