For nearly a decade, America was making slow but meaningful progress on one of its most stubborn social problems — the number of people without health insurance. The Affordable Care Act, introduced in 2010, helped reduce the uninsured population from 46.5 million Americans to a record low of 27.1 million by 2024. But in 2026, that progress is rapidly unraveling — and millions of Americans are about to feel it personally.
Here’s everything you need to know about what’s happening to health insurance in America right now, why it’s happening, and what it means for ordinary families.
Where Things Stood Going Into 2026
According to the U.S. Census Bureau’s most recent report, 92% of Americans — roughly 310 million people — had health insurance for at least some part of 2024. Private insurance remained the dominant source of coverage at 66.1%, with employer-sponsored insurance covering 53.8% of the population. Medicare covered 19.1% and Medicaid 17.6%.
The uninsured rate held steady at 8.2% in early 2024, representing approximately 27.1 million people without any coverage. That was already the result of a difficult period — between March 2023 and September 2024, a staggering 25.2 million people were removed from Medicaid during the “unwinding” of pandemic-era protections that had kept people automatically enrolled regardless of eligibility changes. Around 69% of those removed lost coverage due to paperwork problems and overwhelmed state systems — not because they were actually ineligible.
The gains that remained were largely held in place by one critical policy: enhanced premium tax credits (PTCs) introduced under the American Rescue Plan in 2021 and extended by the Inflation Reduction Act. Those credits were the backbone of the most dramatic expansion of health coverage in American history.
They expired on December 31, 2025.
The Subsidy Cliff: What Just Changed
The enhanced premium tax credits were, in simple terms, government subsidies that made health insurance on the ACA marketplace dramatically more affordable for low and middle-income Americans. They allowed people earning up to 150% of the federal poverty level — roughly $23,000 a year for a single person — to pay $0 in monthly premiums. They also extended subsidy eligibility to households earning above $63,000 annually for the first time, a change that brought millions of previously priced-out middle-income families into the market.
The results were extraordinary. ACA marketplace enrollment doubled from around 11-12 million in 2015-2021 to more than 24 million by 2025. Over 20 million enrollees — 93% of the marketplace — received the enhanced credits. Black and Latino enrollment grew by 186% and 158% respectively between 2021 and 2024.
Now those credits are gone. And the consequences are already being felt.
According to analysis by health research organisation KFF, average out-of-pocket premiums for marketplace enrollees have jumped by 114% in 2026 — from an average of $888 per year to $1,904. For many enrollees, costs more than doubled overnight. The same KFF polling found that 58% of current enrollees believe they cannot afford even a $300 increase in their health insurance payments.
How Many People Are Losing Coverage?
The numbers are sobering. Urban Institute economists estimate that 4.8 million Americans will drop their health coverage and become uninsured in 2026 as a direct result of the subsidy expiry. A further 2.5 million are expected to drop their ACA plan but find alternative coverage elsewhere — through employer plans or Medicaid. Others will downgrade to high-deductible bronze plans with cheaper premiums but much higher out-of-pocket costs when they actually need care.
Early data from the Centers for Medicare and Medicaid Services (CMS) shows that around 1.5 million people had already dropped their ACA marketplace plans by early January 2026 — and this figure only reflects the beginning of the fallout. The full picture won’t be clear until midyear.
The Congressional Budget Office projects the number of uninsured will increase by 2.2 million in 2026 alone, 3.7 million by 2027, and an average of 3.8 million per year from 2026 to 2034. The Commonwealth Fund estimates the overall uninsured population could exceed 40 million by 2034 if current policy trajectories hold — wiping out three-quarters of the coverage progress made since the ACA was signed into law.
Premium Hikes Hitting Everyone, Not Just Marketplace Enrollees
The crisis isn’t limited to ACA marketplace customers. According to analysis by The Century Foundation, nearly 250 million Americans across all types of coverage are facing out-of-pocket premium increases in 2026 that far outpace general inflation, wage growth, and Social Security benefit increases.
The specifics are stark. Medicare Part B premiums — which fund physician and outpatient services for around 64 million older and disabled Americans — have risen from $185.00 to $202.90 per month. That $17.90 monthly increase will consume 33% of the average Social Security cost-of-living adjustment increase for 2026, effectively reducing the real value of Social Security benefits for millions of retirees.
Employer-sponsored insurance costs — the source of coverage for an estimated 164 million Americans — are projected to rise by 9% in 2026, the highest growth rate in 15 years. The average family’s share of premiums, already $6,850 in 2025, could increase by another $617. That’s more than the projected annual increase in rent ($203) or food costs ($144) — meaning health insurance is becoming the single largest driver of household financial pressure for millions of families.
Who Gets Hit Hardest?
The impact is not evenly distributed. The people most severely affected fall into several overlapping categories.
Low and middle-income marketplace enrollees who previously paid nothing or very little for their coverage now face hundreds of dollars in monthly premiums. Many — like Robert and Emily Sory of Tennessee, who were profiled by KFF Health News — have made the painful decision to go uninsured entirely. Robert’s previous premium was $0. His cheapest available 2026 plan is now $70 per month — too much for a household with no income.
Residents of non-Medicaid expansion states are particularly exposed. Ten states — including Texas, Florida, Georgia, Mississippi, and South Carolina — have never expanded Medicaid eligibility to low-income adults. In these states, people who earn too little to qualify for marketplace subsidies but too much to qualify for traditional Medicaid fall into a coverage gap with no safety net at all. The Urban Institute projects uninsured rates could jump by as much as 65% in Mississippi and 50% in South Carolina.
Older Americans near retirement age are hit by a double burden — insurers are legally permitted to charge more for older enrollees, so rising premiums land on top of already-higher baseline costs. Someone like a 63-year-old who is two years away from Medicare eligibility but ineligible for Medicaid has almost no affordable alternative.
People of colour who disproportionately gained coverage under the enhanced subsidies will see those gains partially reversed. According to the Center on Budget and Policy Priorities, the number of uninsured Black Americans in 2026 is projected to increase by 30% — or 925,000 people — the largest rate of increase of any racial or ethnic group.
The Bigger Policy Picture
The subsidy expiry does not exist in isolation. It is part of a broader set of policy changes — most of them tied to Republican legislation passed in 2025 — that are reshaping American healthcare access from multiple directions simultaneously.
The federal reconciliation law passed in 2025 includes cuts to Medicaid and the Children’s Health Insurance Program (CHIP) totalling an estimated $990 billion over ten years, according to the Congressional Budget Office. New work requirements for Medicaid — requiring most adults aged 19-64 to work or participate in qualifying activities for at least 80 hours per month — are set to take effect from January 2027. Research consistently shows that Medicaid work requirements do not increase employment. In 2018, Arkansas implemented similar requirements and 18,000 people lost coverage, with no measurable increase in employment rates.
Additional paperwork requirements, new citizenship verification rules, and shortened open enrollment periods are expected to combine with the premium increases to push millions more out of coverage over the coming years. U.S. News & World Report’s analysis of 2026 health policy changes identifies these compounding policy shifts as among the most significant reshaping of American healthcare access since the ACA itself was passed.
What Can You Do If You’re Affected?
If you or someone you know is facing unaffordable health insurance costs in 2026, there are some options worth exploring.
Check your Medicaid eligibility. Even with the changes underway, Medicaid remains available to low-income individuals and families in expansion states. Visit healthcare.gov or your state’s Medicaid portal to check eligibility.
Use KFF’s premium calculator. KFF has built an online calculator that allows you to estimate exactly how much your health insurance costs may have changed and what options remain available to you based on your income and location.
Look into community health centres. Federally Qualified Health Centres (FQHCs) offer primary and preventive care on a sliding-fee scale regardless of insurance status. Find your nearest centre at findahealthcenter.hrsa.gov.
Consider catastrophic plans if you’re under 30. These plans carry lower premiums but higher deductibles and are designed as a last resort for people who genuinely cannot afford standard coverage.
Check for patient assistance programs. For prescription medications specifically, most major pharmaceutical companies offer patient assistance programs for uninsured or underinsured patients. NeedyMeds.org and RxAssist.org are good starting points.
America is not, in 2026, a country where more people are covered by health insurance. It is a country where coverage gains built painstakingly over a decade and a half are being reversed rapidly by a combination of policy decisions — some deliberate, some the result of congressional inaction — that are pushing millions of ordinary Americans out of the healthcare system entirely.
The human cost of that is real. People without health insurance delay care, accumulate medical debt, receive later-stage diagnoses, and on average die younger than those with coverage. The policy debate may be abstract. The consequences are not.
