OneShare vs ACA plan

OneShare Health and ACA Marketplace Plan solve the same problem in different ways. OneShare is a medical cost-sharing membership that uses monthly shares and published guidelines to determine what medical needs can be shared. It can reduce monthly cost for healthy members who accept non-insurance risk, but it is not regulated as insurance and may limit pre-existing conditions. By contrast, ACA Marketplace plans are comprehensive major-medical insurance that must cover the ten essential health benefits, cannot deny you or charge more for pre-existing conditions, and are the only option eligible for income-based premium tax credits. Depending on income and household size, subsidies can dramatically lower the premium — many enrollees qualify for plans at little or no monthly cost — which makes the Marketplace the default starting point for most people buying their own coverage. Below we compare them on cost, coverage, eligibility, and who each one fits best — with sources you can check.
