The Costco New Locations 2026 Guide: 10 Warehouses Opening This Fall, What to Expect at Grand Opening and Why Your City Might Be Next
The Costco new locations 2026 fall wave is underway — with 10 new U.S. warehouses scheduled to open across October and November 2026, bringing the warehouse club's institutional pricing, $4.99 rotisserie chicken, $1.50 hot dog, and member-exclusive services to communities that have been driving 30 to 45 minutes to the nearest Costco.
Costco is planning to open 10 new stores during October and November 2026. The new branches will be distributed across nine states and are part of the company's expansion strategy, which seeks to open between 25 and 30 warehouses during the year. This fall wave of openings is the specific commercial moment that the communities receiving a new Costco have been anticipating — sometimes for years, since local reporting and construction activity signals a Costco arrival long before the company formally announces it.
The commercial significance for the member in a receiving community: the new warehouse opening brings not just the warehouse floor but the complete Costco member ecosystem — the gas station whose institutional pricing is typically $0.20 to $0.40 below nearby competitors, the pharmacy whose cash pricing on generics is 40 to 80 percent below chain pharmacies, the optical center, the hearing aid center, the food court, and the tire center — all within the driving distance that makes weekly or biweekly warehouse visits commercially rational rather than occasional.
The Fall 2026 Opening Wave: Every New Location
The October 2026 Openings: Five New Warehouses
The first five openings of the fall wave arrive in October 2026 — bringing Costco to new communities in:
Missouri: a new Costco warehouse opening in October 2026 serves the Missouri market where the member community has been underserved relative to the population density and household income profile that Costco's expansion model targets. Missouri Costco members who have been driving to the nearest existing warehouse will have a significantly closer option beginning in October.
Texas: the Texas market continues to receive Costco expansion attention — with the state's population growth, suburban household formation, and above-average household income concentration in its major metropolitan areas creating the specific member density that Costco's economic model requires for new warehouse viability.
The October Texas opening joins a Texas Costco footprint that has been expanding consistently across the past several fiscal years.
New York: the New York state market's expansion — with the Guilderland, New York warehouse that opened in August 2026 and the October addition — reflects the member demand concentration in New York's suburban markets outside the core New York City boroughs, where household income and driving patterns align with the Costco warehouse model.
Kansas: the Kansas market opening communicates Costco's continued attention to Midwestern markets where per-capita Costco penetration has historically lagged the coasts — and where the member community's enthusiasm for the institutional value proposition is high but the warehouse accessibility has been limited by geographic distance.
California: California continues to receive new warehouse openings — reflecting the state's persistent member demand density and the ongoing population growth in specific California markets where existing warehouse locations have reached capacity utilization levels that support additional location investment.
The November 2026 Openings: Five More Warehouses
The second wave arrives in November 2026, bringing five additional new warehouses including:
Newport News, Virginia: the Newport News opening serves the Hampton Roads metropolitan area's Costco member demand — a significant population center whose proximity to existing Virginia Costco locations has historically been sufficient but whose growth has driven demand for a locally accessible warehouse.
Franklin, Wisconsin: the Franklin warehouse serves the Milwaukee metropolitan area's south suburban market — a community that has been identified in local Wisconsin reporting as a Costco destination that members have anticipated for several years based on construction activity and permitting.
The remaining three November openings in the nine-state fall wave complete the specific geographic distribution that Costco's FY2026 U.S. expansion plan identified as the highest-priority underserved markets.
What Happens at a Costco Grand Opening: The First-Member Experience
The Grand Opening Day Dynamic
A Costco grand opening is unlike any other retail opening in American commerce. The specific enthusiasm that a new Costco generates in an underserved community — communities where members have been driving 30 to 45 minutes to the nearest warehouse — produces the specific opening-day experience that first-time grand opening attendees consistently find genuinely surprising.
Lines form before the warehouse opens. The parking lot fills within the first two hours. The food court line extends into the warehouse.
And the warehouse floor itself — fully stocked on opening day at peak inventory, with every department fully displayed and every promotional item available at maximum selection — communicates the institutional abundance that makes the Costco experience most commercially impressive.
The Grand Opening Merchandise Strategy
Costco's buying team ensures that new warehouse openings occur with full inventory across every category — the specific strategic decision that communicates to first-time local members the full scope of what the warehouse carries. The member who visits on opening day sees the mattress section, the jewelry counter, the clothing section, the bakery, the deli, the pharmacy, and the full warehouse assortment at maximum display density.
The specific buying recommendation for grand opening day: resist the impulse to buy everything that appears exciting on opening day.
The opening day's full inventory will be available for weeks. The grand opening's specific commercial value is discovery — learning what the local warehouse carries, identifying the specific products that will anchor the household's regular shopping routine, and establishing the baseline for the price intelligence that makes Costco shopping most financially productive.
The Gas Station Opening Priority
For members in communities receiving a new Costco with a gas station: the gas station's first full week of operation is typically when the institutional pricing differential is most dramatic — because neighboring stations have not yet fully adjusted their pricing to remain competitive with the new institutional alternative.
The strategic first fill-up: arriving at the new Costco gas station in the first week of operation, paying with the Costco Anywhere Visa for the 4% cash back, and experiencing the combined institutional pricing + card reward savings for the first time communicates the specific gas station value that becomes a weekly fixture of the member's financial routine.
The Expansion Strategy: Why Costco Is Building 35 New Warehouses in FY2026
The 35-Warehouse Target and the Building Innovation
Costco's FY2026 target of approximately 35 new warehouse openings — confirmed in Q2 2026 earnings commentary — represents an acceleration from the 29-warehouse FY2025 target.
The specific mechanism for this acceleration: Costco has been open to new warehouse building approaches that reduce construction time and cost, enabling faster community delivery.
The specific building innovation: Costco has confirmed that it is exploring modular and accelerated construction approaches for new warehouses that reduce the typical 18-to-24-month construction-to-opening timeline. The commercial implication: communities that are currently in Costco's pipeline — where construction activity is visible but no opening date has been announced — may receive their new warehouse sooner than historical construction timelines would suggest.
The Approximately 50/50 U.S./International Split
CFO Gary Millerchip confirmed in the March 2026 earnings call that approximately half of the new FY2026 warehouses would be in the United States, with the other half in international markets. The 10-warehouse fall U.S. wave represents a significant portion of the U.S. half of the planned openings — communicating that the fall 2026 period is the heaviest U.S. opening concentration of the fiscal year.
The International Expansion Context
The non-U.S. half of the FY2026 expansion includes the China expansion from 7 to 15 warehouses (the most commercially significant international expansion in Costco's history by growth rate), additional Canada openings, the French and Spanish market expansion, and continued growth in Korea and Japan.
For U.S. members: the international expansion accelerates Costco's global institutional purchasing power — which translates directly into improved pricing leverage with international suppliers and the Kirkland Signature manufacturing partners whose products reach U.S. warehouse floors.
Is Your City Getting a Costco? The 2027 Pipeline
The Communities Currently in the Pipeline
Costco typically does not formally announce new warehouse locations until approximately 90 days before opening — but local reporting, construction permits, and real estate filings reveal Costco's expansion plans significantly earlier.
Communities that local reporting, permits, and construction activity have identified as being in various stages of Costco planning for 2026 and 2027 include markets across the underserved suburban areas of the United States where household income, population density, and driving patterns align with Costco's economic model requirements.
The New Warehouse Location Criteria
The specific criteria that Costco's real estate team applies in evaluating potential new warehouse locations:
Household income threshold: the surrounding trade area's median household income should be at or above the national median — and ideally in the $70,000 to $130,000+ range that the Costco member demographic profile represents.
Population density: sufficient household density within the 15-minute and 30-minute drive radius to generate the member traffic that makes a new warehouse commercially viable at Costco's thin margin model.
Distance from existing warehouses: typically a minimum of 15 to 20 miles from an existing Costco warehouse — the geographic separation that protects existing location traffic while filling underserved geographic gaps.
Real estate economics: the land cost, construction cost, and zoning environment that makes the Costco institutional pricing model sustainable over the 25-to-30-year operating horizon of a new warehouse investment.
How to Find Out If Your Community Is Getting a Costco
The fastest commercially accurate methods for determining whether a specific community is in Costco's pipeline:
Local permit searches: construction permits filed in the community's name for large commercial projects meeting Costco's typical warehouse footprint (approximately 150,000 to 200,000 square feet) are the earliest public signal of a planned Costco opening.
Local business journalism: regional business publications and local newspapers typically report on Costco site acquisition and development applications before the company makes formal announcements. The local commercial real estate reporting that documents zoning variance requests and traffic impact studies is the specific public record that reveals planned Costco openings 12 to 24 months in advance.
Costco's warehouse locator: once formally announced (approximately 90 days before opening), the new warehouse appears in the "Coming Soon" section of Costco's warehouse locator at Costco.com.
The New Member Opportunity: First-Time Members Near New Warehouses
The Grand Opening Membership Promotion
Costco grand openings are typically accompanied by new member recruitment activity — including the occasional first-year membership promotion that reduces the cost of joining at or near a new warehouse opening. The member who joins during a grand opening promotion receives the full membership year at the potentially reduced promotional rate, establishing the relationship with the new local warehouse from the first day of operation.
The First-Year Member Financial Validation
The new Costco member in a community receiving its first warehouse in October or November 2026 has the specific financial validation opportunity that the membership worth-it guide describes:
the first warehouse visit to the new local location — with the rotisserie chicken, the institutional household goods pricing, and the gas station fill-up all available for the first time at driving distance — typically recovers the full annual membership cost in a single well-planned trip.
The community that has been underserved by Costco's geographic distribution is the community whose new members experience the most dramatic first-visit savings relative to their existing grocery and household goods purchasing patterns — because the comparison point is the convenience store, drug store, and grocery store alternatives that the 30-to-45-minute nearest-existing-warehouse distance made them dependent on.
