Segmentation by type classifies Targeted Protein Degraders into PROTACs, molecular glues, SNIPERs, and autophagy‑targeting chimeras (ATCs). PROTACs, the largest class, represent roughly 55 % of the market due to their modular design, extensive patent portfolios, and broad target coverage across intracellular proteins. Molecular glues, accounting for about 25 %, leverage small‑molecule induced proximity without a bifunctional linker, offering simplified synthesis and favorable pharmacokinetics. SNIPERs (Specific and Non‑genetic IAP‑dependent Protein Erasers) hold a 12 % share, distinguished by their reliance on inhibitor of apoptosis proteins to recruit the ubiquitin machinery. ATCs, the emerging niche at 8 %, exploit the autophagy‑lysosome pathway to degrade otherwise “undruggable” targets. The relative contribution of each type reflects differing development timelines, intellectual‑property landscapes, and therapeutic focus, together defining the market taxonomy and informing strategic investment decisions.
