Gate-All-Around (GAA) Transistor Market Surges to USD 2,283.00 Million by 2035, at 12.8% CAGR – Report by SNS Insider

Austin, Sept. 09, 2026 (GLOBE NEWSWIRE) -- According to SNS Insider, the Gate-All-Around (GAA) Transistor Market was valued at USD 685.00 Million in 2025 and is projected to reach USD 2,283.00 Million by 2035, registering a CAGR of 12.8% from 2026 to 2035. Scaling economics in the market are changing due to the migration of foundries and IDMs from FinFET to gate-all-around technology, which allows for better electrostatic control, reduced leakage, and improved switching characteristics below 5nm nodes. The industry is experiencing rapid growth due to the swift changeover from nanosheet to forksheet transistor technology along with the increased adoption of GAA process technology among leading foundries and IDMs.

Taiwan Semiconductor Manufacturing Company further ramped up the volume manufacturing of its N2 (2-nanometer) nanosheet GAA process node throughout the year 2025 in its Hsinchu and Kaohsiung factories, addressing smartphone and high-performance computing end-users. Meanwhile, Intel Foundry progressed towards qualifying its RibbonFet gate-all-around process technology at its 20A and 18A process nodes.
