Who’s at risk
If the Supreme Court upholds a challenge to Obamacare, consumers could retain or lose their subsidies depending on what kind of marketplace they used to buy their insurance.
States fully operating marketplaces will almost certainly maintain subsidies.
States that set up marketplaces but use the federal HealthCare.gov website would probably maintain subsidies.
States that partner with the federal government, but do some insurance regulation, might become state marketplaces and maintain subsidies.
LOSS OF SUBSIDIES
States that depend on the federal government to run health exchanges would probably lose insurance subsidies.
