Eli Lilly $1 Trillion Market Cap Analysis: Drivers, Risks, and Competitive Landscape

Eli Lilly (LLY) achieved a temporary $1 trillion market cap on November 22, 2025, marking a milestone as the first healthcare company to reach this valuation [5]. The surge is fueled by robust demand for its GLP-1 receptor agonist drugs: Zepbound (weight loss) and Mounjaro (diabetes) [2]. Additionally, an upcoming oral drug Orforglipron—expected to receive FDA approval by March 2026—has boosted investor sentiment due to its potential to expand market access [4].

LLY’s stock performance has outpaced peers: up 30.44% month-over-month and +36.20% year-to-date, while competitor Novo Nordisk (NVO) declined -10.77% monthly and -45.58% year-to-date [1][3]. Trading volume for LLY exceeded its average (4.14M vs.3.81M) on the event date, indicating strong investor interest [0].
