Lilly’s Foundayo Quickly Gains Ground in the Oral Weight-Loss Market

Eli Lilly and Company (NYSE:LLY) says its newly launched oral obesity drug Foundayo has captured more than 30% of new U.S. patients starting oral weight-loss medicines, a notable early gain against Novo Nordisk's Wegovy pill. Reuters reports that Wegovy initially held roughly 90% of the oral market, making Lilly's rapid share capture an important sign that the oral GLP-1 market is becoming a two-player competition rather than a Novo-dominated segment. The broader U.S. obesity-drug market is expected to exceed $100 billion annually by 2030, with oral treatments potentially accounting for more than one-third of GLP-1 use. The timing is strategically important for Lilly because Foundayo was only launched in the U.S. in April 2026.
