Eli Lilly — Eli Lilly makes some of the world's best-selling GLP-1 medicines for diabetes and weight loss (Mounjaro, Zepbound). Demand has been so strong that supply — not customers — is often the limiting factor.
Microsoft — Microsoft is three businesses in one: Office and Windows (the classics), Azure (the second-largest cloud), and a huge AI bet through its partnership with OpenAI. Cloud + AI is what the market watches every quarter.
What each company does
Lilly is a global pharmaceutical company with strong franchises in diabetes, obesity, oncology and neuroscience. Its GLP-1 portfolio has redefined how markets value obesity as a therapeutic category.
Microsoft sells software (Office, Windows), cloud computing (Azure), gaming (Xbox, Activision) and enterprise tools. Its investment in OpenAI turned Azure into the default cloud for AI workloads, quietly making Microsoft one of the biggest AI infrastructure players.
