The single source of the world's most advanced transistors. TSMC's N2 is sold out through 2026 with orders pushing into 2028 — and there is no real second supplier at the leading edge.

+3 this quarter — N2 fully booked through 2026 with 78–104 week lead times pushing new orders into 2028, even as TSMC ramps capacity hard.
Every advanced AI accelerator, CPU, and flagship SoC needs a leading-edge node, and at 2nm there is effectively one supplier. Apple takes roughly half of N2 capacity for consumer devices on a fixed schedule, leaving AI chip designers competing for the rest — so foundry allocation gates the entire frontier of compute, sitting alongside CoWoS and HBM in a triple constraint.

What would loosen it
Samsung or Intel closing the leading-edge gap (unlikely near-term), the 200k wpm 2027 ramp, and Arizona capacity. But TSMC's effective monopoly on the frontier keeps N2 sold out into 2028.
