Short answer: For plan year 2026, Delaware has 3 marketplace carriers offering 120 plan options across its 3 counties and 1 rating area. The typical county has 3 carriers to choose from (up to 3), which makes it a moderately competitive market. Full-price premiums for a 40-year-old run from about $468 to $1,020 per month before subsidies, with a median around $742. Most enrollees pay far less after premium tax credits.

Who Actually Sells Marketplace Plans in Delaware
Carrier availability in Delaware is decided county by county, not statewide. A carrier with a big statewide reputation may not file plans where you live, and that single fact drives more of your real options than any national comparison chart. Here is how the 3 carriers in Delaware actually cover the state's 3 counties for 2026:
| Carrier | Counties served | Share of state |
|---|---|---|
| Highmark Blue Cross Blue Shield Delaware | 3 | 100% |
| AmeriHealth Caritas Next | 3 | 100% |
| Ambetter Health of Delaware | 3 | 100% |
Every one of Delaware's 3 counties has at least two competing marketplace carriers, which is better than many states and generally means more network and price choice.
Lowest-Cost Delaware Plan in Each Metal Tier (Age 40)
These are the lowest-premium plans available somewhere in Delaware at each metal level, with the deductible and out-of-pocket maximum that come with them. Premiums shown are full price before subsidies for a 40-year-old; your actual cost depends on your rating area, age, household, and income.
| Tier | Plan | Carrier | Type | Premium (age 40) | Deductible | OOP max |
|---|---|---|---|---|---|---|
| Catastrophic | my Blue Access Major Events Select PPO Catastrophic 10600 - 3 Free PCP Visits | Highmark Blue Cross Blue Shield Delaware | PPO | $468 | $10,600 | $10,600 |
| Expanded Bronze | Everyday Bronze | Ambetter Health of Delaware | EPO | $559 | $8,450 | $10,150 |
| Bronze | AmeriHealth Caritas Next Bronze Essential + No Referrals | AmeriHealth Caritas Next | HMO | $542 | $10,600 | $10,600 |
| Silver | Standard Silver | Ambetter Health of Delaware | EPO | $685 | $6,000 | $8,900 |
| Gold | Clear Gold | Ambetter Health of Delaware | EPO | $727 | $1,200 | $9,150 |
| Platinum | my Blue Access Select PPO Standard Platinum 0 | Highmark Blue Cross Blue Shield Delaware | PPO | $1,015 | $0 | $5,300 |
Reading this table: notice how the premium and the deductible move in opposite directions. A Bronze plan wins on monthly cost and loses badly if you actually use care. The right tier depends on your expected utilization and, critically, whether your income qualifies you for cost-sharing reductions — which only attach to Silver plans.
What Age Does to a Delaware Premium
The ACA lets insurers charge a 64-year-old up to three times what they charge a 21-year-old for the same plan. That age curve, not your health, is the biggest driver of your sticker price. Using Delaware's lowest-cost Silver plan as the reference point:
| Age | Full-price monthly premium |
|---|---|
| Age 21 | $536 |
| Age 27 | $562 |
| Age 30 | $609 |
| Age 40 | $685 |
| Age 50 | $958 |
| Age 60 | $1,455 |
This is exactly why subsidies matter more as you get older: the same income at 60 buys a much larger premium tax credit than at 30, because the credit is calculated against the benchmark plan's cost in your area.
Plan Types and Metal Levels Available in Delaware
Plan types: EPO (51 plans), PPO (45 plans), HMO (24 plans). Plan type governs out-of-network access — HMO and EPO plans typically cover out-of-network care only in an emergency, while PPO and POS designs cover it at higher cost sharing. If keeping a specific hospital or specialist matters to you, that decision comes before price.
Metal levels: Gold (42), Expanded Bronze (36), Silver (30), Platinum (6), Bronze (3), Catastrophic (3). Not every tier is offered in every county, so the mix above is statewide availability rather than a guarantee for your ZIP code.
Before enrolling in any Delaware plan, confirm your hospital and physicians participate in that specific plan's network — not just the carrier's. See how to verify a hospital is in-network.
Subsidies Change These Numbers Completely
Every premium on this page is the unsubsidized sticker price. Premium tax credits are based on household income relative to the federal poverty level and on the benchmark Silver plan in your rating area — which is why two people with identical income in different Delaware counties can receive different credits. If your income falls in the subsidy range, your net premium can be a small fraction of the figures above. If you're self-employed, the calculation runs on your net income after business deductions, which is the single most common place people misestimate and overpay.

Do Delaware marketplace plans cover pre-existing conditions?
Yes. Every ACA marketplace plan in Delaware must cover pre-existing conditions with no waiting period and no health underwriting, and must include the ten essential health benefits. Carriers cannot deny you or charge more because of health history. Premiums vary only by age, ZIP code rating area, household size, and tobacco use.
