In Obamacare's first year, 36 states defaulted to Healthcare.gov, the federally coordinated exchange. An estimated 87 percent of individuals who enrolled through the website are receiving subsidies - the precise subsidies that this court case calls into question. Without subsidies, private insurance become unaffordable for many people who have already enrolled. The judicial process is still playing out, but according to recent analysis from the Robert Wood Johnson Foundation, this decision could affect over 7.3 million people expected to receive federal subsidies in 2016. If the plaintiffs prevail and subsidies are withdrawn, healthy people would drop their coverage, and only the people who are very sick - and therefore very expensive to insure - would keep their plans.
