Costco Wholesale operates as a membership-only warehouse club, providing a wide selection of merchandise across various categories internationally. As a leading player in the retail sector, Costco emphasizes bulk buying and low prices, offering products ranging from groceries and household items to electronics and apparel. The company is renowned for its efficient operations and minimalistic warehouse design, which contribute to a unique shopping experience aimed at delivering maximum value to its members. Before any of that matters to a Muslim investor, one question comes first: is Costco Wholesale stock Halal?
Is Costco Wholesale Shariah compliant?
No. In the October 2026 screening Costco Wholesale (COST) does not pass AAOIFI screening: it fails the non-permissible income screen. Consumer staples companies like Costco Wholesale face the screening question at the shelf, not the balance sheet: does any revenue come from alcohol, tobacco or other impermissible lines? AAOIFI Shariah Standard No. 21 tolerates such income only below 5% of revenue, with the financial ratios checked behind it.
Does Costco Wholesale pass the business activity test?
The activity screen is only part of the picture this month: Costco Wholesale currently fails the non-permissible income screen, so the overall verdict is not compliant regardless of the business itself. The watch item is the product mix: any alcohol, tobacco or similar lines count against the 5% ceiling.
Is Costco Wholesale's income Halal?
No. Costco Wholesale's income from impermissible sources currently exceeds AAOIFI's 5% revenue ceiling, which makes the stock non-compliant on this screen regardless of the others. The screen is reassessed monthly, so the status can change when new financial statements arrive.
Does Costco Wholesale meet AAOIFI's debt and investment ratio requirements?
Yes. Both caps hold this month: interest bearing investments and interest bearing debt each stay below 30% of market capitalisation, measured against a market capitalisation of $404B (market data as of 1 October 2026). Because the caps move with the share price, our Shariah Supervisory Board has COST re-screened every month, and the result above always shows the latest verdict.
Why do other halal screeners show a different verdict for Costco Wholesale?
Screeners can disagree without either being wrong. AAOIFI Shariah Standard No. 21, which Tabadulat applies, measures interest bearing debt and investments against market capitalisation with a 30% ceiling. MSCI and FTSE measure them against total assets with a 33% ceiling, and S&P and Dow Jones Islamic use a multi year average of market capitalisation. Data dates differ too, because each provider reads filings and prices on its own schedule. The same company can therefore pass one standard and fail another in the same month. Tabadulat publishes one answer, the AAOIFI result as of October 2026, and re-screens it every month.
