7 Shocking Insurance Premium Forecasts For 2026: Why Health Costs Are Exploding While Auto Rates Stabilize
As of December 20, 2025, the insurance landscape for 2026 presents a stark and highly polarized picture for consumers and businesses alike. The simple answer to "Are insurance premiums going up in 2026?" is a resounding "Yes," but the severity of the increase depends entirely on the type of coverage you hold. The Property & Casualty (P&C) sector, which includes auto and home insurance, is finally showing signs of stabilization and modest growth, a welcome change after years of extreme rate hikes.
However, this stability is dramatically offset by the Health Insurance market, where proposed rate increases for individual and small group plans are reaching alarming, near-historic levels, driven by underlying medical costs, new federal policies, and economic pressures. Understanding the specific forecast for your insurance category—from the ACA Marketplace to employer-sponsored plans and commercial liability—is critical for preparing your budget for the year ahead.
The Health Insurance Premium Crisis: Double-Digit Spikes Expected for 2026
The most significant financial shockwave in the 2026 insurance outlook comes from the healthcare sector. Proposed premium filings reveal that health coverage is set to become substantially more expensive across the board, making it the primary driver of overall insurance cost inflation for the year. The increases are being fueled by a complex interplay of rising medical trend (the underlying cost of care), high utilization rates, and the expiration or modification of certain government subsidies.
1. ACA Marketplace Premiums: The 18% to 26% Surge
Individual plans purchased on the Affordable Care Act (ACA) Marketplace are facing the most dramatic proposed increases. Insurers in various states have filed for substantial hikes, with the median proposed premium increase nationally hitting approximately 18%. Some analyses suggest the average rate increase for 2026 could be as high as 26% in states that run their own Marketplaces. This massive jump is largely attributed to insurers compensating for the anticipated impact of expiring or changing premium tax credits, which they believe will lead to an unhealthier risk pool and higher overall claims costs.
2. Small Business & Group Plans: Median 11% Increase
Small businesses utilizing small group health plans should also brace for major adjustments. Projections indicate that premiums for these plans are expected to rise by a median of 11% in 2026. This reflects the persistent pressure of the underlying medical trend, which is the estimated increase in the cost of healthcare services. Insurers commonly estimate this cost of healthcare (a function of price and utilization) to be around 9% for 2026.
3. Employer-Sponsored Health Insurance: The 6% to 7% Climb
For the majority of Americans covered by employer-sponsored health insurance, the news is slightly less severe but still concerning. Costs are projected to climb by an average of 6.7%, according to reports from consulting firms like Mercer. Other forecasts place the increase between 6% and 7%, significantly outpacing the current rate of general inflation. This means the average cost per worker for employer-sponsored coverage could reach approximately $18,500.
Property & Casualty (P&C) Market: A Shift Toward Stability
In contrast to the volatile health sector, the Property & Casualty (P&C) market—which encompasses auto, homeowner’s, and commercial property insurance—is entering 2026 on a more stable footing. After several years of aggressive rate hardening due to high inflation, supply chain issues, and catastrophic weather events, the market is beginning to moderate.
4. Overall P&C Premium Growth: Moderating to 3%–4%
Globally and in the US, the overall P&C premium growth rate is projected to slow down. Experts like Swiss Re forecast that US P&C premiums will rise by around 3% in 2026, a notable decrease from the higher growth rates seen in previous years. Other industry outlooks project overall growth around 3% to 4%.
5. Auto and Home Insurance: Competition Returns
The personal lines segment—auto insurance and homeowner's insurance—is seeing increased competition. Insurers have largely caught up to the inflationary pressures on repair costs and replacement values. For customers with a "clean account" (good driving record, no recent claims), pricing is starting to soften and become more favorable, indicating that the market is moving away from the extreme rate hikes of the recent past.
6. Commercial Lines: Stable Profitability, Moderate Increases
Commercial insurance lines, including commercial property and general liability, are poised for a profitable 2026. While rates are not expected to decrease significantly, the rate of increase is expected to be more moderate. Carriers like Amwins note that additional underwriting capacity has tempered rate growth, with companies targeting moderate increases to keep pace with underlying loss trends and maintain profitability.
The Core Drivers of 2026 Insurance Costs
While the specific percentages differ, several powerful, interconnected forces are driving premium adjustments across all insurance sectors in 2026, providing the foundation for the industry’s topical authority and long-term strategy.
- Unrelenting Medical Inflation (Medical Trend): This is the single biggest factor for health insurance. The rising cost of hospital stays, specialty drugs (including new, high-cost therapies), and physician services directly translates to higher premiums.
- Climate Change and Catastrophic Events (CAT Losses): For P&C, the increasing frequency and severity of natural catastrophes—from wildfires to hurricanes—continue to raise the cost of reinsurance and, consequently, the premiums for homeowner’s and commercial property insurance, particularly in high-risk zones.
- Economic and Social Inflation: While general economic inflation is cooling, social inflation (the rising cost of legal settlements and jury awards) continues to put upward pressure on liability lines, including auto and commercial general liability.
- Technological Integration and AI: The global insurance industry is undergoing a "seismic shift" driven by the rise of Artificial Intelligence (AI), cloud computing, and automation. While these technologies promise long-term efficiency, their initial investment and integration costs can influence short-term operational expenses for carriers like TransUnion, Deloitte, and Forrester.
- Regulatory and Policy Changes: New federal and state policies, particularly those impacting the ACA Marketplace and Medicaid, are forcing insurers to adjust their risk models and pricing strategies, leading to the substantial proposed increases in the individual health market.
7. Global Premium Growth: The Headwind of Heightened Competition
On a global scale, the overall premium growth rate is actually expected to decline through 2026. This is driven by two main forces: heightened competition among insurers, which forces them to keep rates competitive, and diminishing rate momentum in certain commercial lines that have already seen years of hard market pricing. This global trend highlights the competitive pressure that is helping to stabilize the P&C market in the US, even as underlying risks persist.
Final Takeaway: Preparing Your 2026 Budget
The 2026 insurance forecast is a clear call for proactive financial planning. While drivers and homeowners may find relief with more competitive P&C rates, the significant escalation in health insurance costs demands immediate attention. Individuals and small businesses should be prepared to shop aggressively during the Open Enrollment Period for the ACA Marketplace and small group plans, as the proposed 11% to 26% jumps are substantial. Leveraging tax credits and exploring high-deductible options will be crucial strategies for mitigating the impact of the rising medical trend and ensuring continued coverage affordability.
