Grocery delivery apps in the USA now range from big-box retailers to restaurant delivery platforms. For example, shoppers can order from Walmart, Instacart, Amazon, Kroger, DoorDash, or Uber Eats. However, each app prices, stocks, and delivers differently, often store by store. So this guide covers the leading apps, the latest market figures, and the data brands can track on each one.

Top Grocery Delivery Apps in the USA at a Glance

US Online Grocery Market Size and Market Share

Online grocery keeps taking share from stores in the US. According to Brick Meets Click, online sales made up over 19% of US grocery spending in the first quarter of 2026. By comparison, that share was under 15% at the end of 2024’s third quarter. Growth has also stayed above 20% a year for six straight quarters.

The pace held through the summer. In August 2026, US eGrocery sales rose 24.9% year on year, while in-store grocery sales fell 4.1%. In fact, 60% of US households bought groceries online that month.

Who Leads US Online Grocery Sales?

These shares come from Brick Meets Click, as reported by Talk Business & Politics. By June 2026, Walmart was approaching a 40% share. However, these figures rank retailers, not delivery apps. So marketplaces such as Instacart and DoorDash do not appear in the table.

The Biggest Grocery Delivery Apps in the USA

Four names lead grocery delivery apps in the USA by sales and reach. Three are retailers, while one is a marketplace that delivers for others.

1. Walmart

Walmart is the biggest online grocery seller in the US, with about 37% of sales at the start of 2026. In its second quarter of fiscal 2027 (May to July 2026), store-fulfilled delivery grew 43%, as Canadian Grocer reported. Moreover, nearly 37% of store-fulfilled US orders arrived in under three hours. Its global e-commerce sales also rose 23% in the quarter.

2. Instacart

Instacart is a marketplace, so it delivers for other retailers instead of selling its own stock. In the second quarter of 2026, its gross transaction value rose 14% to $10.35 billion, from 90.3 million orders. It also works with more than 2,200 retail banners, covering nearly 100,000 stores. For example, Costco’s Same-Day delivery runs on Instacart, and Costco says those prices are higher than in its warehouses.

3. Amazon

Amazon sells groceries through Amazon Fresh, Whole Foods Market and Amazon.com, with a 22.6% share including Whole Foods. In July 2026, Amazon said it offers same-day perishable delivery in 2,300 US cities. Meanwhile, Amazon Now promises delivery in 30 minutes or less in cities such as Atlanta, Seattle, and Dallas-Fort Worth. Prime members pay $3.99 per Amazon Now order.

4. Kroger

Kroger held an 8.6% share of US online grocery sales at the start of 2026. In November 2025, it announced it would close three automated fulfillment centers and lean on partners instead. As a result, Instacart became its primary delivery provider, and its DoorDash partnership widened. Kroger says it can now deliver in as little as 30 minutes. Then, in its second quarter of 2026, adjusted e-commerce sales grew 20%.

More Grocery Delivery Apps in the USA: Marketplaces and Same-Day

Beyond the big retailers, four more grocery delivery apps in the USA compete for orders. Most started in restaurants or convenience, but grocery now matters to each of them.

5. DoorDash

DoorDash added grocery stores to its restaurant marketplace. In its second quarter of 2026, DashPass members placed about 75% of its US grocery and retail orders. The company also reported rising order rates in those categories. In addition, Kroger widened its DoorDash partnership in November 2025.

6. Uber Eats

Uber Eats sells groceries next to restaurant meals. In its Q2 2026 remarks, Uber said grocery and retail had reached $15 billion in annualized gross bookings. Moreover, that business has grown roughly 40% a year for several quarters. Meanwhile, Kroger planned a new Uber Eats experience for early 2026, combining grocery and restaurant orders.

7. Shipt

Shipt is Target’s same-day delivery service. Since May 2025, Target Circle 360 members get same-day delivery from Target and over 100 other retailers on Shipt. Target says those Shipt orders carry no price markups. In addition, members get unlimited same-day delivery on orders over $35.

8. Gopuff

Gopuff delivers from its own network of small warehouses. It also owns the drinks retailer BevMo! In September 2026, Instacart said Gopuff would join its US marketplace. According to both companies, some orders could arrive in as little as 15 minutes. Gopuff also offers 24-hour delivery in some markets.

How Fast Grocery Delivery Apps in the USA Deliver

Speed is now the main battleground for grocery delivery apps in the USA. According to Brick Meets Click, same-day orders were nearly 80% of US delivery orders in 2026’s first quarter. In fact, 18% of delivery orders arrived within an hour. Meanwhile, pickup is fading. Its monthly user base shrank in August 2026, while delivery users grew fastest.

Because each order comes from a nearby store or warehouse, availability depends on the shopper’s location. So brands should track each app by ZIP code, not with a single national price check.

What Data Can You Get From Grocery Delivery Apps in the USA?

Grocery delivery apps in the USA show plenty of public data on every product page. The most useful fields include:

• Product details: name, brand, UPC where shown, pack size and category, so you can match items across apps.
• Prices: shelf price, sale price, and unit price, because pack sizes vary from app to app.
• Promotions: discounts, coupons and member deals, as well as their start and end dates.
• Availability: in-stock or out-of-stock status by store or ZIP code.
• Fees: delivery fees, service fees, and minimum orders, since they change what shoppers pay.
• Search rank and ads: where a product appears for key searches, and whether the slot is sponsored.
• Ratings and reviews: star ratings and review counts for each product.

Why This Data Matters

The same product can cost different amounts on different apps. For example, Costco says its Same-Day prices are higher than in its warehouses. By contrast, Target says Shipt orders for Target Circle 360 members carry no markups. So a brand’s real price depends on the app, the store, and the ZIP code. Without data, those gaps stay hidden.

Who Uses Data From Grocery Delivery Apps in the USA?

Several kinds of teams rely on data from grocery delivery apps in the USA:

1. Consumer goods brands: first, they check their price, stock, and search rank on every app, store by store.
2. Retailers: next, they benchmark prices against Walmart, Amazon, and Kroger in the same ZIP codes.
3. Retail media teams: they track sponsored slots, because apps now sell ads. For instance, Instacart says over 9,000 advertisers can extend campaigns to Gopuff’s storefront.
4. Investors and analysts: they follow price changes and store coverage to judge growth.
5. Delivery startups: finally, they study fees, delivery times, and coverage gaps before they launch.

In each case, the value comes from comparing apps side by side, not from one app alone. To learn more, see our grocery data scraping API and competitor price monitoring service.

Grocery Delivery Apps in the USA: Trends for 2027

Five trends will shape grocery delivery apps in the USA in 2027:

1. Faster delivery: Amazon says Amazon Now will reach tens of millions of customers by the end of 2026. Meanwhile, Kroger already promises delivery in as little as 30 minutes.
2. Partners over warehouses: Kroger closed automated centers and turned to Instacart, DoorDash, and Uber Eats. Similarly, Gopuff is joining Instacart’s marketplace.
3. Restaurant apps in grocery: Uber’s grocery and retail arm has grown about 40% a year. So expect more grocery push from restaurant apps.
4. Memberships: DashPass members placed about 75% of DoorDash’s US grocery and retail orders. In addition, Target Circle 360 bundles same-day Shipt delivery.
5. Retail media: apps sell more ads, so sponsored slots increasingly decide what shoppers see first.
