Cheapest ACA plans in Wyoming for 2026

Cheapest plans by metal tier

Lowest 2026 monthly premium for a single 40-year-old non-tobacco user, on-exchange, before any subsidy. Per-age figures derived from the CMS QHP Landscape file using the HHS standardized age-rating curve (45 CFR 147.102).

The actual cheapest plan in major counties

Same data the search returns: carrier, plan name, monthly premium, individual deductible, individual MOOP. Computed for a single 40-year-old non-tobacco user, before any subsidy. Catastrophic plans excluded because adults 30+ typically need a hardship-exemption certificate to enroll.

The actual cheapest plan for a family of four

Two 40-year-old adults and two kids in the 0-14 age band, before any subsidy. Carrier, plan name, premium, deductible, and MOOP exactly as the search would return them.

Subsidies: federal APTC only (no state premium subsidy)

Wyoming does not operate a state-funded premium assistance program, state reinsurance program, or §1332 waiver for the individual market. Marketplace help is federal only:

1. Federal Advance Premium Tax Credit (APTC). Households 100-400% FPL on the PY2026 standard ACA contribution curve. The ARPA / IRA enhanced subsidies expired 2025-12-31 and are not in effect for 2026, so the hard 400% FPL cliff is back and subsidized net premiums are meaningfully higher than PY2025 for most enrollees.
2. Federal cost-sharing reductions (CSRs). Households 100-250% FPL enrolled in a Silver plan receive reduced deductibles, copays, and out-of-pocket maximums automatically.

Wyoming has not adopted ACA Medicaid expansion. Wyoming Medicaid for non-disabled adults is extremely narrow (parents below roughly 59% FPL, pregnant women, and categorically needy groups), and childless adults are generally ineligible regardless of income. Adults 19-64 with income below 100% FPL who do not fit these categories sit in the coverage gap: ineligible for Medicaid and ineligible for federal APTC.

Catastrophic plans in Wyoming follow federal rules

Wyoming follows the federal ACA default: Catastrophic plans are available to enrollees under age 30, or at any age with a hardship / affordability exemption. The PY2026 federal auto-expansion applies: adults 30+ automatically qualify when the lowest-cost Bronze plan exceeds the affordability threshold. APTC does not apply to Catastrophic plans.

Tobacco surcharges follow the federal 1.5x default in Wyoming

Wyoming applies the federal ACA default (45 CFR 147.102): carriers may charge tobacco users up to 50% more than non-users (a 1.5-to-1 rate ratio). The Wyoming Department of Insurance reviews rate filings under Wyo. Stat. Title 26. No Wyoming-specific cap below the federal 1.5x ceiling has been identified. Federal APTC does not offset the tobacco portion of the premium.

Carriers selling 2026 plans in Wyoming

3 carriers, 851 plans across 23 counties. 529 sold on Healthcare.gov, 322 off-exchange-only direct from carriers. Wyoming runs the smallest (or near-smallest) Marketplace in the country. Two carriers compete: Blue Cross Blue Shield of Wyoming (an independent BCBS licensee, broad statewide footprint) and Mountain Health CO-OP, the last remaining ACA Consumer Operated and Oriented Plan (co-op), which also serves Idaho and Montana.
