Whether you are researching Bristol-Myers Squibb Company on its own, evaluating Eli Lilly and Company, or weighing the two companies side by side, the breakdown below highlights where each company leads and where the gap between Bristol-Myers Squibb Company and Eli Lilly and Company is widest.

On the headline numbers, annual revenue is $48.2B (FY2025) for Bristol-Myers Squibb Company and $65.2B (FY2025) for Eli Lilly and Company, while their respective market capitalizations stand at $127.5B and $1.06T. Both Bristol-Myers Squibb Company and Eli Lilly and Company are headquartered in United States. Their local markets and applicable rules may still differ.

Bristol-Myers Squibb Company: Bristol Myers Squibb (BMS) is a U.S. biopharmaceutical company headquartered in Princeton, New Jersey, and listed on the New York Stock Exchange as BMY. It develops and sells prescription medicines for cancer, blood disorders, immune diseases, heart disease and schizophrenia. Its best-known products are Eliquis, the anticoagulant it sells with Pfizer, and Opdivo, a PD-1 checkpoint inhibitor. With $48.2 billion of 2025 revenue and a market value of about $127 billion at the end of September 2026, it is one of the largest U.S. drugmakers by sales. The massive biopharmaceutical titan was formed in New York City, New York through the 1989 mega-merger of two historic drug companies, eventually becoming an absolute powerhouse in modern cancer immunology.

Eli Lilly and Company: Eli Lilly is a 150-year-old Indianapolis pharmaceutical company that has become the world's largest drugmaker by market value. For most of its history it was best known for insulin and Prozac. Since 2022, tirzepatide, a dual GIP/GLP-1 agonist sold as Mounjaro for type 2 diabetes and Zepbound for obesity, has transformed its scale, taking revenue from $28.5 billion in 2022 to $65.2 billion in 2025 and a guided $85-87 billion in 2026. The company is headquartered in Indianapolis, Indiana.

Bristol-Myers Squibb Company and Eli Lilly and Company pursue distinct approaches to generating revenue, and understanding how each company operates is the foundation of any fair comparison between Bristol-Myers Squibb Company and Eli Lilly and Company.

Bristol-Myers Squibb Company business model: BMS discovers, licenses or buys drug candidates, takes them through clinical trials, and sells approved medicines under patent protection to wholesalers, specialty pharmacies and hospitals. Net product sales were $46.8 billion of the $48.2 billion total in 2025; alliance, royalty and other revenues made up the remaining $1.4 billion, including royalties from Merck on Winrevair. Eliquis is developed and sold with Pfizer, which shares its costs and profits. About 69 percent of 2025 revenue came from the United States, so U.S. pricing policy matters more to BMS than to most European rivals. Because every patent runs out, the model depends on replacing revenue: BMS paid $74 billion for Celgene in 2019, $13.1 billion for MyoKardia in 2020 and about $23 billion for Karuna, Mirati and RayzeBio in early 2024.

Eli Lilly and Company business model: Lilly makes money by discovering, developing, manufacturing and selling patent-protected prescription medicines. Revenue comes mainly from product sales to wholesalers, pharmacies and health systems, with net prices set through negotiations with insurers, pharmacy benefit managers and governments; collaboration and royalty income adds a smaller share. Cardiometabolic medicines dominate: Mounjaro ($22.97 billion) and Zepbound ($13.54 billion) together produced about 56% of 2025 revenue. Lilly also sells directly to self-pay patients through LillyDirect, including Zepbound vials and Foundayo tablets, which reduces reliance on traditional pharmacy benefit channels for obesity care.

The durability of a company's moat often decides long-term winners. Here is how the competitive advantages of Bristol-Myers Squibb Company stack up against those of Eli Lilly and Company.

Bristol-Myers Squibb Company competitive advantage: BMS's advantage is its expertise in oncology and its large commercial and regulatory organization. Developing a cancer immunotherapy is complex, and winning approval from regulators and getting doctors to prescribe it requires an established global sales and regulatory team. Smaller biotech companies often lack that infrastructure, so they partner with or sell to a company like BMS to bring their discoveries to market.

Eli Lilly and Company competitive advantage: Lilly's advantage combines a century of diabetes and peptide-hormone expertise with manufacturing scale few rivals can match. Tirzepatide's dual GIP/GLP-1 mechanism produced greater weight loss than semaglutide in the head-to-head SURMOUNT-5 trial, and Foundayo gives Lilly a small-molecule GLP-1 pill that can be taken without food or water restrictions and is easier to mass-produce than peptides. Heavy investment in U.S. and European plants lets Lilly supply volume growth that competitors struggle to match.

Future prospects matter as much as current results. The growth strategies below explain how Bristol-Myers Squibb Company and Eli Lilly and Company each plan to expand from here.

Bristol-Myers Squibb Company growth strategy: BMS is pursuing growth on three fronts. First, scaling the Growth Portfolio (Opdivo Qvantig, Reblozyl, Camzyos, Breyanzi, Opdualag, Cobenfy and others), which rose 17 percent to $26.4 billion in 2025 and 15 percent to $7.56 billion in the second quarter of 2026. Second, buying and licensing late-stage science: Mirati ($4.8 billion plus a contingent value right of up to $1 billion), RayzeBio ($4.1 billion) and Karuna ($14 billion) closed in early 2024; a June 2025 deal with BioNTech for the bispecific BNT327 carried $1.5 billion upfront and up to $11.1 billion in total; and Orbital Therapeutics was bought for $1.5 billion in October 2025 for in vivo CAR-T in autoimmune disease. Third, cost cuts: a $1.5 billion savings program announced in 2024 was extended in 2025 with a further $2 billion targeted by the end of 2027.

Eli Lilly and Company growth strategy: Lilly's growth strategy has three parts: expand incretin supply and indications, add oral and next-generation obesity medicines, and diversify through oncology, immunology, neuroscience and genetic medicine. Foundayo (orforglipron) was approved by the FDA on April 1, 2026 and launched through LillyDirect, telehealth and U.S. retail pharmacies. Retatrutide, a GIP/GLP-1/glucagon triple agonist, is in Phase 3. Lilly continues to build U.S. and European manufacturing capacity and uses acquisitions to add pipeline assets.

A closer look at the financial trajectory of Bristol-Myers Squibb Company and Eli Lilly and Company rounds out the comparison.

Bristol-Myers Squibb Company: Revenue grew from $19.4 billion in 2016 to $42.5 billion in 2020 as Celgene's sales were added, and has stayed between $45.0 billion and $48.3 billion since 2021. Net earnings are far less stable because BMS expenses acquired in-process R&D: the $11.4 billion MyoKardia charge produced a $9.0 billion net loss in 2020, and the Karuna charge produced an $8.9 billion loss in 2024. Cash generation is steadier, with free cash flow of about $12.8 billion in 2025. That cash funds a dividend raised for a 17th straight year in February 2026, to $0.63 a quarter, and debt reduction, from $51.2 billion at the end of 2024 to $47.2 billion a year later. On July 30, 2026 BMS raised its 2026 revenue guidance to $49.0 to $50.0 billion, from $46.0 to $47.5 billion, after second-quarter revenue rose 6 percent to $12.97 billion. Bristol Myers Squibb is a dominant force in global biopharmaceuticals, sustaining a massive market valuation that regularly exceeds $100 billion.

Eli Lilly and Company: Revenue rose from $28.5 billion in 2022 to $45.0 billion in 2024 and $65.2 billion in 2025, while net income nearly doubled to $20.6 billion. Growth accelerated again in 2026: second-quarter revenue rose 48% to $23.0 billion, with Mounjaro at $9.94 billion (up 91%) and Zepbound at $4.93 billion. Lilly raised 2026 revenue guidance to $85-87 billion and non-GAAP EPS guidance to $35.50-36.50. Capital expenditures reached $7.8 billion in 2025 as Lilly expanded production capacity. Eli Lilly and Company is a pharmaceutical titan that has experienced massive growth, commanding a monumental market valuation frequently exceeding $700 billion.
