The Supreme Court hears arguments Tuesday in a case that could invalidate the entire Affordable Care Act. If that’s the Justices’ decision, it would likely—and instantly—become the largest business and economics story of 2021.
The hearing on Tuesday will provide early hints of which way the Justices are leaning. The plaintiffs—18 states with Republican governors, led by Texas, plus two individuals—argue that the Affordable Care Act, also known as Obamacare, is unconstitutional. A ruling to that effect would upend U.S. health care, the largest sector of the world’s largest economy, accounting for 18% of America’s GDP.
