The eCommerce landscape continues to evolve, with online grocery shopping emerging as one of its fastest-growing segments. In the United States, online grocery sales are projected to reach $238 billion in 2025, reflecting a shift in consumer behavior driven by convenience and technology. Among the companies leading this transformation is Instacart, which has grown to become a household name for millions of Americans.
Instacart’s rise has been nothing short of remarkable, from its modest beginnings to holding a significant portion of the online grocery market. By examining Instacart’s growth and market share from 2017 to 2025, we can better understand its impact on the industry and its future trajectory.
This year, Instacart is projected to maintain a 21.6% market share of the U.S. online grocery market, the same as the previous year.

This means that over $1 in every $5 spent on online groceries will be processed through Instacart. Maintaining such a significant share in a market valued at $238 billion demonstrates the platform’s resilience and relevance amid growing competition.

2017–2019: The Early Years
Instacart started with a modest 3.7% market share in 2017, competing with industry giants like Amazon and Walmart. The platform’s appeal lay in its partnerships with grocery retailers and its promise of same-day delivery, which resonated with busy households.
By 2019, Instacart’s share had grown to 10.2%, driven by its expansion into new markets and partnerships with national chains like Kroger, Costco, and Aldi. It surpassed Target to become the third-largest online grocery retailer in the U.S.
2020: The Pandemic Boom
The COVID-19 pandemic in 2020 was a turning point. Lockdowns forced millions of Americans to rely on online grocery shopping, and Instacart’s market share more than doubled to 21.5%. The company hired 300,000 additional drivers in one month to meet the surge in demand, solidifying its status as a market leader.
2021–2024: Stabilization and Slight Fluctuations
After its explosive growth during the pandemic, Instacart’s market share stabilized. It maintained 21.5% in 2021, then edged up to 21.6% in 2022 and 21.8% in 2023, its highest point. However, competitive pressures from Amazon Fresh and Walmart led to a slight decrease to 21.6% in 2024.
What Makes Instacart a Market Leader?
Instacart’s consistent market presence is the result of several key factors:
Strategic Partnerships
Instacart’s ability to partner with over 1,000 grocery stores has been a cornerstone of its success. These partnerships give customers access to a vast selection of products from trusted brands. Retailers like Kroger, Safeway, and Publix rely on Instacart to extend their reach and compete in the online space.
Convenience and Flexibility
Instacart’s model offers customers the convenience of same-day delivery, often within hours. The personal shopper experience, where groceries are hand-picked and delivered to the customer’s doorstep, has been a key differentiator.
Pandemic-Driven Expansion
During the pandemic, Instacart adapted quickly by scaling operations to meet skyrocketing demand. This included onboarding thousands of new drivers and ensuring timely deliveries, which helped cement its reputation as a reliable service.
User-Friendly Technology
The Instacart app and website are designed with simplicity in mind. Features like personalized recommendations, real-time tracking, and easy substitutions enhance the shopping experience, encouraging repeat use.
Challenges Facing Instacart
While Instacart remains a major player, it faces several challenges that could impact its growth:
Intensifying Competition
Amazon Fresh and Walmart, with their vast resources and established customer bases, are Instacart’s biggest competitors. Both companies are aggressively expanding their online grocery operations, using price cuts and innovative delivery solutions to attract more customers.
Rising Costs
The operational costs of maintaining a large network of personal shoppers and delivery drivers have increased. These costs, combined with inflation and wage increases, may pressure Instacart’s profitability.
Market Maturity
As online grocery shopping becomes more common, the rapid growth seen during the early years is slowing. Instacart must find new ways to differentiate itself to maintain its market share.
Opportunities for Future Growth
Despite these challenges, Instacart has several opportunities to grow and innovate:
Subscription Services
Instacart+ (formerly Instacart Express) offers unlimited free deliveries for a monthly fee, encouraging customer loyalty. Promoting this subscription model could drive sustained revenue.
Expansion into New Markets
While Instacart is currently focused on the U.S., international expansion could unlock new revenue streams. Countries with emerging eCommerce markets present an opportunity for growth.
Enhanced Technology
By leveraging artificial intelligence, Instacart could improve delivery efficiency and customer personalization. AI-driven recommendations and route optimization are just a few ways technology could enhance the user experience.
The Competitive Landscape
While Instacart holds 21.6% of the online grocery market, its competitors are not far behind:
- Amazon Fresh: With its advanced logistics network, Amazon commands a 22% market share and continues to attract customers with same-day delivery and competitive pricing.
- Walmart: Holding approximately 19% of the market, Walmart benefits from its vast physical store network and affordable delivery fees.
Instacart’s focus on partnerships and convenience has helped it carve out a strong position despite the stiff competition.
From its humble beginnings in 2017 with just 3.7% market share, Instacart has grown to dominate over a fifth of the U.S. online grocery market by 2025. Its partnerships with leading grocery chains, focus on convenience, and ability to adapt during the pandemic have positioned it as a trusted service for millions of households.
While challenges like rising competition and operational costs exist, Instacart’s ability to innovate and expand ensures it remains a key player in the eCommerce grocery space. As online grocery shopping continues to evolve, Instacart is well-equipped to navigate the future and maintain its leadership.
Whether you’re a busy professional or simply seeking convenience, Instacart remains a go-to platform for seamless online grocery shopping.
