Delaware's ACA Marketplace has three insurers for 2026: AmeriHealth, Ambetter and Blue Cross Blue Shield. That limited field simplifies comparison shopping but removes the competitive pressure that drives down premiums in larger state markets. In our analysis of Silver-tier plans for 40-year-olds, the cheapest option (Ambetter at $719 monthly) and the most expensive (Blue Cross Blue Shield at $849 monthly) are $130 apart. That $130 gap is also the only meaningful premium spread available to Delaware shoppers.
Delaware is one of only a handful of states where plan-type choice eliminates carrier competition entirely: if you want a PPO, you have one option; if you want an HMO, you have one option. That structural constraint makes comparing across plan types more important than comparing within them.
One pattern in our Delaware data surprised us: all three insurers apply almost the identical age-based premium increase between age 40 and age 60. Ambetter, AmeriHealth and Blue Cross Blue Shield each raise Silver-tier premiums by 112% over that 20-year span. That uniformity means age-based rate shopping won't produce savings in Delaware the way it might in larger state markets with more carriers.
