Costco Is Opening New Warehouses This October, Here’s Where Shoppers Can Expect Them
If a Costco run already feels like a road trip, some shoppers are about to get a much shorter commute.
Costco is continuing its U.S. expansion, with new warehouse openings planned across several states. The retailer’s expansion is particularly interesting because these aren’t tiny neighborhood stores: Costco warehouses are enormous operations designed to serve large numbers of members, often with fuel stations and other services attached. Costco’s own current locations page confirms October openings including Lee’s Summit, Missouri; The Colony, Texas; and Amherst, New York.
October Is Bringing Costco to More Shoppers
If you’ve been waiting for a Costco closer to home, this is the kind of announcement worth paying attention to.
Reports about the expansion point to a larger group of warehouses opening around October and November, with locations spread across states including Missouri, Texas, New York, and others. Some are completely new markets for the company, while others replace existing warehouses with larger or improved facilities.
That distinction matters because a new Costco isn’t always about putting the first warehouse in a city. Sometimes the company moves into a larger nearby building so it can offer members more space, services, and inventory.
Lee’s Summit, Missouri
Missouri shoppers have a particularly interesting addition coming to the Costco map.
Costco lists Lee’s Summit among its October 2026 openings, giving shoppers in the Kansas City-area community another major warehouse option. For a retailer built around bulk shopping, location matters enormously: the closer the warehouse, the easier it becomes to justify those oversized packs of paper towels, snacks, and pantry staples.
And, of course, the real danger is going in for milk and walking out with a cart full of things you never knew you needed.
The Colony, Texas
Texas remains one of the places where Costco’s enormous warehouses make plenty of sense.
Costco also lists The Colony as an October opening. The city sits in the rapidly growing northern part of the Dallas-Fort Worth region, making it the kind of densely populated area where a large membership warehouse can attract plenty of shoppers.
For regular Costco members, another nearby warehouse can also mean less pressure on existing stores, especially during busy weekends and holiday shopping periods.

Amherst, New York
New York is getting another reason for shoppers to plan a bulk-buying expedition.
Costco’s official locations page also lists Amherst, New York, for October. The new warehouse is particularly notable because Costco’s expansion strategy isn’t simply about putting stores anywhere there is empty land. The company has to find locations that can support a huge warehouse, parking, traffic, and the infrastructure that comes with it.
The Costco expansion details show just how much attention these openings are attracting from shoppers who have been waiting for a warehouse in their area.
Why Costco Keeps Building Bigger
A Costco warehouse is basically a small retail city under one enormous roof.
The typical warehouse is far larger than an ordinary grocery store, allowing Costco to sell everything from fresh food and household supplies to electronics, furniture, and seasonal merchandise. The company also relies heavily on membership fees, so opening in areas with enough potential members is crucial.
That helps explain why Costco tends to focus on growing population centers and areas where the surrounding road network can handle substantial traffic.
More Than Just a Shopping Trip
For longtime members, a new warehouse can change the way they shop.
A closer store means easier access to bulk groceries, pharmacy services, fuel where available, and the famous rotating selection of unexpected finds. One week you might be buying chicken and coffee; the next, you’re standing in front of a giant display of patio furniture wondering whether you suddenly need a new outdoor kitchen.
Coverage of the latest Costco locations also points to a much broader expansion picture, with dozens of locations announced or planned across the country.
Some States Are Still Waiting
Even with all this expansion, Costco hasn’t reached every corner of the United States.
Reports on the company’s growth note that Rhode Island, West Virginia, and Wyoming remain the only states without a Costco warehouse. That makes the company’s expansion particularly interesting for residents in those states, who keep watching each new announcement, hoping their state finally makes the list.
For now, Costco is continuing to build where it sees enough demand to support the warehouse-sized footprint. And if your city isn’t on the list yet, that doesn’t necessarily mean it has been forgotten. Costco’s growth plans indicate that the company expects to continue opening warehouses in the coming years.
For shoppers who love buying giant quantities of food, discovering unexpected seasonal products, and somehow spending far more than planned, another nearby Costco may sound less like retail expansion and more like a convenient excuse for another shopping trip.
That is also why simple everyday routines can sometimes get a little more interesting when your local warehouse suddenly has a whole new selection to explore.
If Costco announced a new warehouse in your area tomorrow, what would be the first thing you would put in your oversized cart?
