Least Competitive Insurance Markets Inspire Solutions for Brighter Future
Commercial health insurance markets in the United States have long been scrutinized for their lack of competition. According to the American Medical Association’s (AMA) 2024 “Competition in Health Insurance” report, nearly half of the nation’s local markets are dominated by a single payer. This trend raises significant concerns for consumers and healthcare providers alike.
Overview of the American Medical Association’s Findings
The AMA’s annual report provides a detailed analysis of commercial insurance market concentration across metropolitan areas. Key findings include:
- 95% of metropolitan areas have “highly concentrated” markets.
- In 89% of these areas, a single payer controls at least 30% of the market across HMO, PPO, point-of-sale, and exchange markets.
- In 47% of markets, a single insurer holds a dominant share of 50% or more.
These figures underscore the critical need for increased competition to ensure affordability and choice for consumers.
The Impact of Market Concentration
High market concentration can lead to several challenges, including:
- Higher Premiums: Limited competition often allows dominant insurers to set higher prices.
- Reduced Innovation: With fewer competitors, there is less incentive to innovate or improve services.
- Limited Provider Choices: Dominant payers may restrict provider networks, limiting patient options.
States with the Least Competitive Insurance Markets
Alabama
- Largest Payer: Blue Cross Blue Shield (BCBS)
- Market Share: 86%
BCBS dominates Alabama’s insurance market, leaving little room for competitors.
Kentucky
- Largest Payer: Elevance
- Market Share: 67%
Elevance’s significant presence restricts competition in Kentucky’s health insurance sector.
Michigan
- Largest Payer: BCBS
- Market Share: 67%
In Michigan, BCBS controls a substantial portion of the market, limiting consumer options.
Louisiana
- Largest Payer: BCBS

Louisiana’s insurance market sees similar dominance from BCBS.
Illinois
- Largest Payer: BCBS
- Market Share: 63%
BCBS also holds a commanding position in Illinois, stifling competitive forces.
Hawaii
- Largest Payer: BCBS
- Market Share: 63%
Hawaii’s small market size makes it especially vulnerable to concentration.
South Carolina
- Largest Payer: BCBS
- Market Share: 59%
BCBS continues its dominance in South Carolina, impacting affordability and choice.
Oklahoma
- Largest Payer: BCBS
- Market Share: 57%
In Oklahoma, BCBS maintains a strong foothold, controlling a majority of the market.

- Market Share: 56%
Elevance’s significant market share highlights the need for competitive reforms.
Delaware
- Largest Payer: Highmark
- Market Share: 56%
Highmark’s dominance in Delaware exemplifies the challenges of market concentration.
Implications of Market Dominance
The lack of competition in these states affects both consumers and healthcare providers. Dominant payers may negotiate lower rates with providers, which can impact the quality of care. Meanwhile, consumers face limited plan options and higher premiums.
Strategies for Improving Competition
Addressing market concentration requires coordinated efforts, including:
- Regulatory Oversight: Enforcing antitrust laws to prevent monopolistic practices.
- Encouraging New Entrants: Providing incentives for smaller insurers to enter the market.
- Promoting Transparency: Requiring insurers to disclose pricing and performance metrics to foster competition.
Conclusion
The AMA’s findings highlight a critical issue in the U.S. healthcare system—limited competition in commercial insurance markets. States like Alabama, Kentucky, and Michigan demonstrate the adverse effects of market dominance, including higher premiums and restricted choices. Addressing these challenges will require a multi-faceted approach involving regulators, insurers, and healthcare providers.
