**Strong pre-reported sales momentum underpins the 89.5% market-implied probability that Costco will beat fiscal Q4 2026 estimates.** The company posted $93.9 billion in net sales for the 16-week quarter ended August 30, up 11.3% year-over-year, with comparable sales rising 9.4% (6.7% excluding fuel and foreign exchange). Digital-enabled comparable sales continued to grow near 20%, while membership fee income has expanded steadily at double-digit rates amid renewal rates above 89%. Analysts project EPS of roughly $6.53–$6.55 (about 11–12% growth from $5.87) and revenue near $94.85–$94.89 billion on September 24 after the close. Costco’s recent quarters have shown consistent outperformance on both top- and bottom-line metrics, giving traders high visibility into the print ahead of full results that will also cover margins, expenses, and any tariff-related items.

As of market creation, Costco is estimated to release earnings on September 24, 2026. The Street consensus estimate for Costco's GAAP EPS for the relevant quarter is $6.69 as of market creation. This market will resolve to "Yes" if Costco reports GAAP EPS greater than $6.69 for the relevant quarter in its next quarterly earnings release. Otherwise, it will resolve to "No." The resolution source will be the GAAP EPS listed in the company’s official earnings documents.
If Costco releases earnings without GAAP EPS, then the market will resolve according to the GAAP EPS figure reported by SeekingAlpha. If no such figure is published within 96h of market close (4:00:00pm ET) on the day earnings are announced, the market will resolve to “No”.
If the company does not release earnings within 45 calendar days of the estimated earnings date, this market will resolve to “No.”
Note: Subsequent restatements, corrections, or revisions made to the initially announced GAAP EPS figure will not qualify for resolution, except in the case of obvious and immediate mistakes (e.g., fat finger errors, as with Lyft's (LYFT) earnings release in February 2024).
Note: The strike prices used in these markets reflect the selected street consensus estimate for GAAP EPS as of market creation.
Note: All figures will be rounded to the nearest cent using standard rounding.
Note: For the purposes of this market, IFRS EPS will be treated as GAAP EPS.
Note: GAAP EPS refers to diluted GAAP EPS, unless this is not published, in which case it refers to basic GAAP EPS.
Note: All figures are expressed in USD, unless otherwise indicated.
Note: For primarily internationally listed companies, this market refers specifically to the shares traded in the United States on U.S. stock exchanges such as the NYSE or Nasdaq. In cases where the company trades in the U.S. through an American Depositary Receipt (ADR) or American Depositary Share (ADS), this market will refer to the ADR/ADS.
