The stocks of companies that make the new class of drugs to treat obesity and manage diabetes were higher across the board early Tuesday, after the Biden administration proposed a rule that would allow Medicare or Medicaid to cover the expensive medications.

The Biden administration proposed a rule for Medicare and Medicaid to cover the costs of weight-loss drugs for millions of Americans with obesity.

The plan would need to be supported by the incoming Trump administration, which has vowed to cut costs across the federal government.

This may be the first Thanksgiving for millions of Americans who are on GLP-1 agonists like Ozempic, Zepbound or Wegovy.

The proposal would expand coverage of anti-obesity drugs to 7.5 million people covered by Medicare and Medicaid, the Biden administration said.
