Costco Wholesale (COST) Stock Forecast: What Could Drive It in 2026
Short answer
No one can reliably forecast COST's price, and Walnut does not publish targets. What is useful is the setup. For Costco Wholesale, the drivers that could push it higher are real, and so are the risks that could weigh on it. Below is each side plus a framework to form your own view. This is descriptive, not a prediction or a recommendation.
What could drive Costco Wholesale (COST) higher?
1. Membership fee growth.
Costco raised the Gold Star membership fee from $60 to $65 and Executive from $120 to $130 in 2024, the first increase in seven years. Future increases will follow the same pattern: infrequent, but enormously accretive to operating income when they happen. Each new member is essentially pure profit at the margin.
2. International expansion.
Costco continues to expand internationally, with new warehouses in China, Sweden, France, and other markets each year. International stores often outperform US stores on early-year revenue. The runway for store growth is long.
3. E-commerce and Costco Next.
Costco's e-commerce business is growing faster than warehouse sales but remains a smaller portion of revenue. Costco Next (a curated direct-from-manufacturer e-commerce platform) is the more interesting recent strategic initiative.
4. Inflation-resistant value positioning.
When consumers are squeezed, the value proposition of warehouse club membership strengthens. Costco has historically gained share during recessions because households increase basket sizes and consolidate purchases.
What could weigh on 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.
How to think about a COST forecast
Rather than chasing a price target, it tends to help to weigh the drivers above against the risks, decide how long you are willing to hold, and size the position so a wrong call is survivable. A “forecast” is really a probability-weighted view of those drivers playing out, not a number.
For the full picture, see the COST guide and whether COST is a buy. In Walnut you can pressure-test the thesis against your real portfolio.
The bottom line on the COST outlook
The honest bottom line: Costco Wholesale (COST)'s outlook hinges on whether its drivers (above) outpace its risks, and no one can promise which wins. Treat any COST forecast as a scenario, not a certainty, and decide from your own thesis and time horizon. Walnut is not an investment adviser.
