The checkpoint inhibitor market is about to stop growing in its core. Keytruda and Opdivo begin losing exclusivity from 2028, and the market peaks at $75.7 billion in 2028 before biosimilars pull it down.

The checkpoint inhibitor market is about to stop growing in its core. Keytruda and Opdivo begin losing exclusivity from 2028. The winners of the next five years will be the challengers with early-stage labels, not the incumbents, and PD-(L)1/VEGF bispecifics remain an expensive, unproven bet rather than the next standard backbone.

Market Size and Growth Outlook

This report estimates the global checkpoint inhibitor market at $64.7 billion in 2026. It grows to a peak of $75.7 billion in 2028 and then declines to $71.4 billion in 2031 as biosimilars arrive, a compound annual growth rate of 2%.

Market Size 2026: USD $64.7B Market Size 2031: USD $71.4B CAGR: 2%

Key Market Drivers

  • The Patent Cliff Arrives: Keytruda and Opdivo lose exclusivity from 2028 and the first Keytruda biosimilar filing was accepted in October 2026. We expect brand erosion to start earlier than the 2033 timing many analysts assume.
  • Biosimilars Become a Major Segment: Pembrolizumab and nivolumab biosimilars grow from nothing in 2028 to $15.6 billion in 2031, 22% of the market, with Samsung Bioepis and Formycon/Zydus first in line.
  • Growth Moves Earlier and to the Challengers: Perioperative and first-line use grow while later-line use shrinks. Imfinzi, Libtayo, Opdualag and China-originated PD-1s are the growth brands, and bladder cancer is the fastest-growing indication.
  • The Bispecific Money Arrived Before the Proof: PD-(L)1/VEGF bispecifics have attracted more than $25 billion in headline value, but the HARMONi-3 interim miss leaves the class unproven globally. The November 14 FDA decision on ivonescimab is the next test.

Market Segmentation

The report forecasts the market by indication, target, product, molecule format and treatment setting, for 14 countries and regions, from a 2026 base year.

Competitive Landscape

Keytruda carries about half of Merck & Co.'s revenue into the patent cliff; Keytruda Qlex and the Padcev combination slow the loss but do not stop it. Bristol Myers Squibb is the next most exposed, with Opdivo eroding. AstraZeneca's Imfinzi is the biggest brand winner, built on curative-intent indications and a later loss of exclusivity. Summit Therapeutics and Akeso's ivonescimab is the most important test of the bispecific thesis. Roche's Tecentriq holds its niches, and Samsung Bioepis is first with global Phase 3 data for a Keytruda biosimilar. The report profiles 25 companies.
