Eli Lilly became the largest publicly traded pharmaceutical company by market capitalization after demand for its weight-loss drugs surged.
Eli Lilly’s market value rose sharply as investors assessed the commercial potential of tirzepatide, marketed as Mounjaro for type 2 diabetes and Zepbound for chronic weight management. These medicines act on hormonal pathways involved in blood-sugar control and appetite regulation.
The company was founded in 1876 in Indianapolis by Colonel Eli Lilly, a pharmaceutical chemist and Civil War veteran. Its long history includes insulin, antibiotics, psychiatric medicines, and treatments for diabetes and cancer.
Market capitalization is not the same as annual pharmaceutical sales or a company’s total assets. It is the value of the company’s publicly traded equity at current share prices. Novo Nordisk, maker of semaglutide products such as Ozempic and Wegovy, is the most common company confused with Eli Lilly in this area.
