Walmart’s Domination of the U.S. Grocery Market
Walmart’s Domination of the U.S. Grocery Market
One wouldn’t expect the grocery department of a big box retailer to spark debate, but Walmart’s high market concentration in the grocery space is doing just that.
By now, Walmart’s rise to the top of the retail pyramid is well documented. The Supercenters that dot the American landscape have had a dramatic ripple effect on surrounding communities, often resulting in decreased competition and reduced selection for consumers. Today, in some communities, Walmart takes in a whopping $19 for every $20 spent on groceries.
Today’s map, based on a report from the Institute for Local Self-Reliance, looks at which places in America are most reliant on Walmart to put food on the table.
The Weight of Walmart
Walmart has an unprecedented amount of control over the food system, now capturing a quarter of every single dollar spent on groceries in the United States.
Walmart isn’t just a major player — in some cases it’s become the only game in town. In a few of the communities listed in the report, Walmart commands a 90% market share and higher.
Here’s a breakdown of the top 20 towns dominated by Walmart in America:
Rank | Metro/Region | Population | Walmart Market Share |
---|---|---|---|
#1 | Atchison, Kansas | 16,580 | 95% |
#2 | Portales, New Mexico | 19,730 | 95% |
#3 | Sterling, Colorado | 22,068 | 91% |
#4 | Deming, New Mexico | 24,699 | 90% |
#5 | Guymon, Oklahoma | 21,385 | 90% |
#6 | North Platte, Nebraska | 37,043 | 87% |
#7 | Wahpeton, N.D.– Minnesota | 23,036 | 84% |
#8 | Coffeyville, Kansas | 33,434 | 83% |
#9 | Othello, Washington | 19,806 | 83% |
#10 | Bismarck, North Dakota | 135,654 | 83% |
#11 | Helena-West Helena, Arkansas | 20,176 | 80% |
#12 | Altus, Oklahoma | 25,931 | 77% |
#13 | Parsons, Kansas | 20,761 | 77% |
#14 | Miami, Oklahoma | 32,260 | 77% |
#15 | Sweetwater, Texas | 15,101 | 77% |
#16 | Grenada, Mississippi | 21,706 | 76% |
#17 | Huron, South Dakota | 18,082 | 75% |
#18 | Greensburg, Indiana | 26,711 | 74% |
#19 | Clarksdale, Mississippi | 25,085 | 74% |
#20 | Dumas, Texas | 22,485 | 74% |
While it’s more likely for a small town to become dominated by a single grocer, Walmart’s clout isn’t exclusive to rural America. Even in Springfield, Missouri — with a regional population of half a million people — the big box retailer still boasts a sizable market share of 66%.
Super Market Concentration
Under guidelines established by the Justice Department’s Antitrust Division, markets in which one corporation captures more than 50% of revenue are defined as “highly concentrated.” Walmart’s market share meets or exceeds this measure in 43 metropolitan areas and 160 smaller markets around the United States.
In some states, this trend is even more pronounced. In Oklahoma, for example, 86% of the state’s population lives in a region where Walmart has the majority market share in the grocery sector. In Arkansas — the home state of the megaretailer — half the population lives in this “highly concentrated” grocery market situation.
This degree of market concentration means that a retailer could cut certain products or manipulate prices without fear of losing customers. Worse yet, a company could close up shop and leave thousands of people without adequate grocery access.
An Interesting Caveat
There is a flip side to this story, however.
Walmart has shown a willingness to expand their grocery business to areas that were considered “food deserts” (i.e. low-income areas without easy access to a supermarket).
In a 2011 initiative, the retailer committed to open or expand 1,500 supermarkets across America to help give more people access to fresh food.
With the ground game clearly won, America’s largest grocer is now focused on dominating the next frontier of the grocery market – delivery. Stiff competition from companies like Amazon and Instacart will keep Walmart’s online market concentration in check for the time being.

Graphene: An Investor’s Guide to the Emerging Market
The market value of graphene could reach $3.75 billion by 2030. As the emerging industry shows fast growth, it also faces obstacles.


Graphene: An Investor’s Guide to the Emerging Market
Graphene is an atomic-scale “honeycomb” that is revolutionizing the world of materials and capturing investor attention.
Experts predict that its market value could reach the billion-dollar threshold by 2027 and soar to a staggering $3.75 billion by 2030.
In this infographic sponsored by HydroGraph, we dive into everything investors need to know about this exciting industry and where it’s headed.
Promising Properties
Graphene possesses several unique physical properties which contribute to its wide range of potential applications.
- 200 times stronger than steel
- Harder than diamonds
- 1,000 times lighter than paper
- 98% transparent
- Higher electrical conductivity than copper
- Heat conductivity: 5 times that of copper
- 2,630 m² of surface area per gram
Since its first successful isolation in 2004, graphene’s properties have opened the doors to a multitude of commercial applications and products.
Applications of Graphene
Graphene has permeated numerous sectors like electronics, energy, and healthcare because of its impressive array of end uses.
Industry | Revenue CAGR of Graphene Across Industries, 2022-2027 |
---|---|
Biomedical and Healthcare | 52% |
Electronics and Telecommunications | 34% |
Energy | 25% |
Aerospace and Defense | 16% |
Other End-User Industries | 17% |
Graphene’s antibacterial properties make it highly suitable for medical instruments and implants. Furthermore, it has shown remarkable potential in helping treat diseases such as cancer.
Another one of the material’s applications is its ability to emit high-speed light pulses, or to combine graphene’s thinness and high-conductivity to create the tiniest possible light sources.
All in all, it’s difficult to sum up graphene’s properties and potential applications in one place. The supermaterial has been covered and cited in thousands of academic journals, and comes up with over 2 million search results on Google Scholar.
Graphene Commercialization
Graphene has evolved from a scientific breakthrough to a commercial reality in less than two decades, putting it firmly on the radar of many future-focused investors.
But despite the strides the industry is making, it is still in its infancy, and therefore challenges exist on the path to widespread adoption. Here are the top five commercialization obstacles perceived by industry players.
Obstacle | % of survey respondents |
---|---|
Cost | 31% |
Production Methods, Scaling, and Distribution | 21% |
Material Quality/Consistency | 17% |
Lack of Knowledge/Awareness | 15% |
Dispersion/Handling | 14% |
When transitioning cutting-edge materials from the laboratory to consumer products, challenges like these can be expected. But one company is tackling them head-on.
By producing 99.8% pure graphene, and ensuring batch-to-batch consistency, HydroGraph is helping meet the growing demand for graphene products across industries while addressing challenges like cost, scale, and quality.
