For the more than 20 million Americans who purchase health insurance through the Affordable Care Act marketplaces, 2026 is bringing an unwelcome reality check. The median proposed premium increase across 312 insurers is 18%—the largest in the program's history—while enhanced subsidies that helped millions afford coverage have expired, leaving many facing dramatically higher out-of-pocket costs.

The double blow of higher premiums and reduced subsidies is creating what health policy experts call the most significant affordability crisis since the ACA's rocky 2013 launch. For some enrollees, the premium increase effectively triples their monthly costs.

Understanding the 18% Increase

The 18% median premium increase reflects several factors that are simultaneously squeezing insurers:

  • Medical Cost Trends: Insurers commonly assumed medical costs would trend upward 7-8% in 2026, driven by labor shortages, inflation, and utilization rebounds
  • Specialty Drug Costs: High-cost biologics and gene therapies are increasingly common, with some insurers explicitly citing specialty drugs as a key driver
  • GLP-1 Medications: Weight-loss drugs like Ozempic and Mounjaro are adding billions in costs across the health system
  • Post-Pandemic Utilization: Care deferred during COVID-19 is being caught up, driving higher claims
  • Risk Pool Changes: The expiration of enhanced subsidies may cause healthier enrollees to drop coverage, worsening the risk pool

The 18% figure is a median—meaning half of insurers are proposing even larger increases. In some states and for some plans, proposed hikes exceed 25%.

"This is an extraordinary increase by historical standards. We've never seen premium pressure of this magnitude in the ACA marketplaces."

The Subsidy Cliff

Compounding the premium increases, enhanced ACA subsidies—implemented through the American Rescue Plan in 2021 and extended through 2025—have now expired. These enhanced subsidies:

  • Eliminated the 400% federal poverty level income cap for subsidy eligibility
  • Capped premiums at 8.5% of income for all enrollees, regardless of income
  • Made coverage effectively free for many low-income Americans
  • Extended subsidies to middle-income households previously ineligible

With the enhancements gone, an estimated 7-8 million people will see their subsidies reduced or eliminated entirely. For subsidized enrollees, the average premium after tax credits is rising from $37 per month in 2025 to $50 per month in 2026 for the lowest-cost plan—a 35% increase even with remaining subsidies.

For those losing subsidy eligibility entirely, the shock is more severe. A 60-year-old earning $60,000 annually might have paid $200 monthly in 2025 with enhanced subsidies. In 2026, without enhancement, the same person could face $600 or more monthly—an increase that makes coverage unaffordable.

Medicare Part B Also Rising

The premium pressure extends beyond the ACA marketplaces. Medicare Part B premiums are jumping nearly 12% next year to $206.50 monthly—one of the largest increases in the program's history. The increase reflects higher spending on drugs administered in clinical settings and overall medical cost inflation.

For retirees on fixed incomes, the Medicare increase compounds Social Security cost-of-living adjustments that haven't kept pace with healthcare inflation. The result is declining real purchasing power for healthcare among the elderly.

Small Business Impact

Small businesses purchasing group coverage face similar pressures. The median proposed premium increase among small group insurers across all 50 states is 11%—lower than the individual market but still substantially above general inflation.

Small businesses have fewer tools to absorb these increases than large employers. Many are responding by:

  • Shifting more costs to employees through higher deductibles and copays
  • Reducing coverage options or benefits
  • Dropping coverage entirely and directing employees to the ACA marketplace
  • Exploring association health plans and other alternatives

What's Driving Long-Term Costs

Beyond 2026's specific pressures, structural factors suggest healthcare costs will continue outpacing general inflation:

  • Aging Population: Healthcare costs rise dramatically with age; the population is getting older
  • Technology and Innovation: New treatments extend lives but at enormous cost
  • Administrative Complexity: The U.S. spends far more on healthcare administration than peer nations
  • Provider Consolidation: Hospital and physician group mergers reduce competition and increase prices
  • Drug Pricing: Pharmaceutical prices in the U.S. remain far higher than in other developed countries

Without structural reform, health insurance affordability will continue deteriorating regardless of which party controls Washington.

Navigating the 2026 Market

For Americans facing higher premiums, several strategies may help:

  • Shop Aggressively: Premium increases vary dramatically between insurers; switching plans may save money
  • Consider Higher Deductibles: Bronze and Silver plans with larger deductibles have lower premiums
  • HSA Maximization: High-deductible health plans paired with Health Savings Accounts offer tax advantages
  • Verify Subsidy Eligibility: Income changes may affect subsidy amounts; update applications promptly
  • Medicaid Review: Some previously ineligible households may now qualify for Medicaid

The Policy Debate Ahead

The premium shock is reigniting debate over ACA subsidies and broader healthcare reform. Democrats argue for restoring and making permanent the enhanced subsidies. Republicans counter that subsidies mask underlying cost problems and distort insurance markets.

Whatever the policy outcome, the immediate reality for millions of Americans is stark: health insurance in 2026 will cost significantly more than it did in 2025. For those already struggling to afford coverage, the increases may force impossible choices between healthcare, housing, and other essential needs.
