In the evolving landscape of oncology, investors are faced with crucial decisions about where to allocate their resources. While ImmunityBio has gained attention for its rapid growth and innovative therapies, it presents a level of volatility that may not suit every investor’s appetite for risk. In contrast, Merck emerges as a more stable option, offering a robust portfolio and a solid track record in the biopharmaceutical sector.

The Oncology Landscape
Oncology remains the largest segment within the biopharma industry, commanding significant sales and attention from both healthcare providers and investors. Despite the rising interest in diabetes and weight-loss drugs, oncology is unlikely to lose its position as a lucrative therapeutic area. The potential for groundbreaking treatments continues to attract investment and innovation, making it a focal point for companies like ImmunityBio and Merck.
ImmunityBio’s Promise
ImmunityBio has made headlines with its cancer treatment Anktiva, which received U.S. approval for invasive bladder cancer in 2024. The drug demonstrated remarkable growth, with reported revenues of $113 million for 2025—an impressive 668% increase from the previous year. However, the timeline of Anktiva’s market presence raises questions about the sustainability of this rapid growth.
While the initial success of Anktiva is noteworthy, its long-term viability hinges on several factors. ImmunityBio is actively pursuing expansion into new markets, including the European Union and Saudi Arabia, and is conducting clinical trials for additional indications such as lung cancer and lymphoma. Yet, the company operates in an inherently risky environment where clinical trials can falter and regulatory hurdles can arise.
Valuation Concerns
Despite its promising pipeline, ImmunityBio’s valuation poses a significant risk. With a market cap of $9.7 billion and sales below $500 million last year, the company’s high expectations may not align with its current financial performance. Investors must grapple with the possibility that if Anktiva fails in later-stage trials or encounters commercial barriers, the company’s stock could experience a steep decline.
Merck’s Stability
In stark contrast, Merck offers a more stable investment profile. While it may not boast the same explosive growth as ImmunityBio, Merck has consistently delivered reliable revenue and earnings, largely driven by its flagship product, Keytruda. This best-selling cancer medication is approved for a wide range of cancers and has secured over 30 indications in the U.S. alone.
Keytruda’s patent expiration in 2028 looms, yet Merck has strategically prepared for this event by developing a subcutaneous formulation that enhances ease of administration. This innovation is expected to retain patient interest and safeguard revenue streams, making it a valuable asset in the company’s long-term strategy.
A Robust Pipeline
Merck’s growth trajectory is bolstered by a diverse pipeline of new therapies and ongoing clinical trials. The company is actively pursuing advancements in oncology, with over four dozen trials underway to expand the indications of existing drugs and introduce new therapies. This proactive approach ensures that Merck remains at the forefront of cancer treatment innovation.
Moreover, Merck’s pipeline extends beyond oncology, with successful products like Winlevi, which addresses pulmonary arterial hypertension, already contributing to the company’s bottom line. This diversification not only mitigates risk but also positions Merck as a formidable player across various therapeutic areas.
Strategic Market Positioning
As Merck ventures into exciting new markets, the potential for growth in oncology is enhanced by the exploration of next-generation therapies. The company is developing bispecific antibodies, a novel class of drugs poised to capture significant market share in the coming decade. This strategic positioning underscores Merck’s commitment to being a leader in cancer therapy advancements.
Conclusion
In summary, while ImmunityBio’s recent achievements are impressive, the volatility and inherent risks associated with its growth may deter conservative investors. Merck, with its established portfolio, consistent revenue generation, and extensive pipeline, emerges as the safer and more reliable choice for those looking to invest in next-generation cancer therapies. As the biopharmaceutical landscape continues to evolve, Merck stands poised to deliver steady growth and innovation, making it a compelling option for investors seeking stability in an unpredictable market.
