Oncology gene therapy is a CAR-T market, and it is becoming a myeloma market. The first CAR-T products are fading, bladder cancer is the one real growth story outside CAR-T, and in vivo CAR-T, despite billions spent on acquisitions, is a story for after 2031 rather than a driver of this forecast.Oncology gene therapy is a CAR-T market, and it is becoming a myeloma market. The market nearly doubles from $7.1 billion in 2026 to $13.6 billion in 2031.
Market Size and Growth Outlook
This report estimates the global oncology gene therapy market at $7.1 billion in 2026, growing at 14.1% a year to $13.6 billion in 2031, with Carvykti alone reaching $5.1 billion.Market Size 2026: USD $7.1B Market Size 2031: USD $13.6B CAGR: 14.1%
Key Market Drivers
- Myeloma Overtakes Lymphoma: BCMA CAR-T therapies lift myeloma revenue from $2.8 billion to $5.4 billion, making it the largest indication by 2031, and Carvykti grows to 37% of the market.
- The First Generation Fades: Kymriah, Abecma and Tecartus decline by about 14% a year as Breyanzi, Carvykti and bispecific antibodies take their patients.
- Bladder Cancer Is the Breakout Outside CAR-T: Adstiladrin grows six-fold to $450 million, and cretostimogene and the non-viral detalimogene are approaching regulatory filings.
- Big Pharma Paid Early for the Next Generation: Gilead's $7.8 billion Arcellx acquisition and about $5 billion of in vivo CAR-T acquisitions buy future options, but we expect little in vivo revenue before 2031.
Market Segmentation
The report forecasts the market by approach, vector, indication, product and route of administration, for 14 countries and regions, from a 2026 base year.Competitive Landscape
Johnson & Johnson and Legend Biotech's Carvykti is the market leader and its main growth engine. Bristol Myers Squibb's Breyanzi is the fastest-growing CD19 CAR-T, while Abecma loses share in myeloma. Gilead (Kite) depends on anito-cel, with an FDA decision due in December 2026, as Yescarta and Tecartus decline. Ferring's Adstiladrin leads bladder cancer gene therapy, CG Oncology's cretostimogene is the leading bladder challenger, and Replimune's RP1 is the test of whether oncolytic viruses can succeed commercially.
