Which US Pharmaceutical Companies Are Leading Market Growth in 2024?

The global pharmaceutical landscape continues to evolve rapidly, with industry revenues surpassing the US$1.6 trillion mark in 2023 and projections pointing toward US$1.7 trillion by 2030 for prescription drugs alone. Among the key drivers of this expansion are the US pharmaceutical companies that dominate worldwide markets.

The Market Leaders: Where Pharma Giants Stand

North America remains the epicenter of pharmaceutical growth, largely due to the dominance of major US pharmaceutical companies. These industry titans collectively shape drug innovation, development pipelines and therapeutic strategies across oncology, immunology, cardiovascular care and beyond.

Dominant Forces in Global Pharma

Johnson & Johnson (NYSE:JNJ) maintains its commanding position with 2023 revenues reaching US$85.16 billion. As one of the most influential US pharmaceutical companies, J&J operates across research, manufacturing and commercialization with particular strength in five therapeutic domains: immunology, infectious diseases and vaccines, neuroscience, oncology, and cardiovascular-metabolic health. The company’s oncology division alone generated US$17.66 billion in sales, while its immunology flagship Stelara climbed to US$10.86 billion annually. Leadership projects sustained 5-7% annual growth through 2030, backed by an ambitious pipeline of blockbuster candidates.

Roche Holding (OTCQX:RHHBF,SWX:RO) secured the second-largest position with US$65.32 billion in revenue despite currency headwinds. Operating dual divisions in pharmaceuticals and diagnostics, the Swiss-headquartered company competes fiercely in oncology and rare diseases. Its eye disease therapeutic Vabysmo is reshaping the competitive landscape, while hemophilia treatment Hemlibra expanded 16% to US$4.6 billion.

Merck & Company (NYSE:MRK) climbed to third place with US$60.1 billion in revenue, driven primarily by its cancer checkpoint inhibitor Keytruda—the world’s top-selling pharmaceutical at US$25 billion globally in 2023. This single asset represents 41% of the company’s total revenue, creating both opportunity and vulnerability as patent protection approaches 2028.

Reshaping the Competitive Order

Pfizer (NYSE:PFE) experienced the most dramatic shift in fortune among major US pharmaceutical companies. After reaching US$100.33 billion in 2022 revenues, the company contracted 41% to US$58.5 billion as COVID-19 product demand normalized. However, excluding pandemic-related products, core pharmaceutical sales actually expanded 7%, signaling underlying business resilience. The December 2023 acquisition of Seagen for US$43 billion represents a strategic pivot toward oncology innovation.

AbbVie (NYSE:ABBV) faces a critical transition with US$54.3 billion in 2023 revenues. As Humira—historically one of the world’s best-selling drugs—confronts biosimilar competition following US market exclusivity loss, the company is redirecting focus toward immunology platforms Skyrizi and Rinvoq to maintain growth momentum.

Rising and Specialized Players

Sanofi (NASDAQ:SNY) advanced two positions to sixth place with US$46.6 billion in revenue. As the world’s largest vaccine manufacturer through subsidiary Sanofi Pasteur, the company benefits from expanding approvals for its flagship dermatology treatment Dupixent across multiple indications.

AstraZeneca (NASDAQ:AZN) posted US$45.81 billion in revenue with 3.3% growth, driven by oncology expansion. The division achieved 20% gains to reach US$17.1 billion, with lung-cancer therapy Tagrisso contributing US$5.8 billion and immuno-oncology combinations Imfinzi and Imjudo surging 55% to US$4.2 billion combined.

Novartis (NYSE:NVS,SWX:NOVN) reported US$45.44 billion in revenue following its strategic spinoff of generics business Sandoz. Growth was anchored by heart disease therapy Entresto and multiple sclerosis injection Kesimpta, each exceeding US$6 billion and US$2 billion in sales respectively.

Bristol-Myers Squibb Company (NYSE:BMY) holds ninth position with US$45 billion in revenue, navigating a transition as Revlimid loses ground. The company is banking on blockbuster anticoagulant Eliquis and oncology asset Opdivo, though new pricing regulations under the Inflation Reduction Act will pressure growth starting 2026.

GSK (NYSE:GSK,LSE:GSK) rounds out the top 10 with US$38.4 billion in revenue, buoyed by its shingles vaccine Shingrix gaining 17% and newly approved RSV vaccine Arexvy targeting seniors.

The Bigger Picture for US Pharmaceutical Companies

The 2024 landscape underscores a fundamental shift: while US pharmaceutical companies maintain their commanding market position, success increasingly depends on diversification beyond single blockbuster drugs and adaptation to evolving regulatory environments. Patent cliffs, biosimilar erosion and pricing pressures are forcing industry restructuring, with M&A activity and strategic portfolio reorientation becoming essential survival strategies.

The pipeline of these companies collectively represents humanity’s best hope for addressing complex diseases, but their continued dominance will hinge on innovation velocity and ability to navigate an increasingly complex healthcare economy.
