Idaho's health insurance market is more stable than most states. A 1332 State Innovation Reinsurance Waiver sets aside separate funding to cover high-cost enrollees, which held Idaho's 2026 average rate increase to 10%.
In our analysis of every 2026 Idaho Silver-tier plan, the spread between the lowest monthly premium and the highest across the three top-rated carriers is $45. That gap sounds small. But the deductible spread across those same plans runs from $3,000 to $6,250. The finding that surprised us most: the rate gap between a 40-year-old and a 60-year-old on the same Molina plan is $585 per month. That's larger than the entire gap between any two carriers at the same age. For older enrollees, the age curve matters more than the carrier choice.
