The federal Affordable Care Act created health insurance marketplaces for some people to purchase individual insurance plans with the help of federal subsidies. Most states let the federal government run their marketplaces for them but California runs its own.

The announcement came on the same day that President Joe Biden signed an executive order declaring a special enrollment period for states served by the federal marketplace.

Earlier this month, Covered California said nearly 1.6 million people had purchased health insurance through the marketplace.
