Fusion42 · 1 October 2026 · Fusion42 review

TSMC's 3-nm semiconductor process has reached 30% of wafer revenue in Q2 2026, nearing the 5-nm process share, with expectations it could become the largest revenue source for TSMC in the latter half of 2026.

This Wire brief sits within Fusion42's coverage of Semiconductors, and 8 sources have reported it between 14 Sep 2026 and 1 Oct 2026.

◆ ◆ The Wire takeaway

TSMC's 3-nm process is becoming a dominant revenue stream faster than historical ramps. You should prepare for a shift in chip supply availability and potential pricing changes that will affect product design and sourcing decisions.
