Eli Lilly became the first pharmaceutical company to reach a $1 trillion market capitalization.
Eli Lilly crossed the threshold in 2024 as investors placed enormous value on its diabetes and obesity medicines, especially Mounjaro and Zepbound. These drugs belong to a fast-growing class of treatments that mimic hormones involved in blood-sugar regulation and appetite control.
The company was founded in 1876 by Colonel Eli Lilly in Indianapolis, Indiana. It developed a long-term focus on medicines and became a major producer of insulin, psychiatric drugs and other therapies before its recent growth in metabolic medicine.
Market capitalization is not the same as annual pharmaceutical sales. Investor expectations about future prescriptions, manufacturing capacity, patent protection and clinical results can move a drugmaker’s share price well before revenue fully reflects those expectations.
