Is Costco Open on July 4, 2026? Hours, Membership Data & the Rotisserie Chicken Upset
Is Costco Open on July 4, 2026? Full Holiday Hours, Membership Data & the Chicken Upset
Costco is closing all U.S. warehouses for Independence Day this year — one of just seven days the retailer shuts down nationwide. Here's the full holiday schedule, what it means for the company's underlying business model, and why Consumer Reports just handed Costco's beloved $4.99 rotisserie chicken its first real challenger in years.
Search interest in "Costco hours" spiked to more than 50,000 monthly searches this week — a predictable but consequential surge every time a major U.S. holiday lands on a weekday. Unlike most big-box retailers, which stay open with reduced hours on holidays, Costco takes a firmer stance: seven days a year, every single warehouse in the country simply doesn't open. This year, July 4 is one of them.
1. Costco's Full July 4, 2026 Hours
| Date | Status | Notes |
|---|---|---|
| Thursday, July 2, 2026 | Open | Normal warehouse hours |
| Friday, July 3, 2026 | Open | Normal hours; expect heavier pre-holiday crowds |
| Saturday, July 4, 2026 | Closed | All warehouses, gas stations, pharmacies, tire centers closed nationwide |
| Sunday, July 5, 2026 | Open | Resumes normal Sunday hours |
Costco's own official holiday closures page is the authoritative source for this schedule and should be checked directly, since individual warehouse hours — particularly for Business Centers, which cater to restaurant and office customers — can vary by location and are worth confirming before a trip.
2. The 7 Holidays Costco Closes For
Costco's full-closure policy applies to seven specific dates each calendar year, regardless of which day of the week they fall on:
- New Year's Day
- Memorial Day
- Independence Day (July 4)
- Labor Day
- Thanksgiving Day
- Christmas Day
- Easter Sunday (most locations)
Beyond these full closures, several other dates carry shortened "weekend-style" hours rather than a full closure — for example, Christmas Eve and New Year's Eve typically see an early 8:30 AM opening and a 5:00 PM closing, giving staff time to get home for the holiday itself.
3. Why Costco Closes When Competitors Stay Open
Sam's Club, Walmart's warehouse-club subsidiary, remains open on July 4, 2026, albeit on a shorter schedule at many locations — a genuine strategic divergence between the two largest warehouse retailers in the country. Costco's leadership has described the closures as a deliberate trade-off: forgoing a portion of potential holiday sales in exchange for employee goodwill and retention, a stance the company has maintained even as year-round shopping expectations have become more common among consumers.
4. The Business Behind the Closures
Costco's willingness to forgo a shopping day rests on a membership-fee-driven business model that is somewhat insulated from single-day sales swings. In its third-quarter 2026 earnings call, Costco reported $1.37 billion in membership fee income and a 92.2% member renewal rate across the U.S. and Canada — figures that illustrate why the company can prioritize long-term member loyalty over maximizing every possible operating hour.
5. The Rotisserie Chicken Upset
Separately from the holiday schedule, Costco's famous $4.99 Kirkland Signature rotisserie chicken — a price the company has held steady for years despite broader grocery inflation — has a new challenger. Consumer Reports purchased chickens from 10 major grocery chains and warehouse clubs, transporting them warm to a lab for blind sensory testing alongside sodium and packaging-chemical analysis.
The result: Sam's Club's Member's Mark Seasoned Rotisserie Chicken was named the top overall pick, narrowly ahead of Costco's bird. Testers attributed the edge to a paprika-forward seasoning rub that delivered a more consistent, complex roasted flavor, while noting Costco's chicken varied more noticeably in saltiness from sample to sample. Both chickens were priced identically at roughly $1.66 per pound, so the gap reflected taste rather than value.
| Rank Tier | Retailer | Notable Detail |
|---|---|---|
| Top Pick | Sam's Club | Paprika rub; most consistent seasoning across samples |
| Best Overall | Costco | Plump size; some sample-to-sample saltiness variation |
| Best Overall | Stop & Shop, Walmart, Wegmans, Whole Foods | Also rated flavorful enough to serve on their own |
| Recipe Use | BJ's, Hannaford, ShopRite, The Fresh Market | Recommended for soups, salads and other recipes |
Consumer Reports also flagged a food-safety note worth passing along: chicken from Costco and Walmart showed the highest levels of a plastic-associated chemical among the retailers tested, though within levels the organization described as below its threshold of concern. Its general guidance is to transfer rotisserie chicken out of its plastic packaging soon after purchase and consume it within a few days.
6. Costco vs. Sam's Club vs. BJ's — July 4 Status
| Retailer | Open July 4, 2026? | Notes |
|---|---|---|
| Costco | Closed | All US locations, company-wide |
| Sam's Club | Open | Some locations on shortened hours |
| Walmart | Open | Normal hours at most stores |
| Target | Open | Normal hours at most stores |
| Home Depot | Open | Reduced hours, typically closing by 8 PM |
7. Shopping Tips for the Holiday Weekend
- Shop July 2–3 rather than waiting. The two days before a major Costco closure are consistently among the busiest of the season.
- Plan for a full return to normal hours July 5. No extended post-holiday closure is expected.
- Check your local warehouse directly for Business Center hours, since these often follow a different schedule than standard warehouses.
