Intel's fab roadmap hinges on two critical 2026 deadlines: 14A customer commitments and CHIPS Act tax credit

Intel's capacity roadmap now turns on two clocks running out within months of each other. CEO Lip-Bu Tan told investors in January that 14A customers will begin making firm supplier decisions 'starting in the second half of this year and extending into the first half of 2027.' Separately, the enhanced 35% advanced manufacturing investment credit signed into law applies only to fab construction that begins before December 31, 2026; projects breaking ground in 2027 get nothing. Both deadlines affect the same construction projects, creating a cascading decision window.

Arizona's Fab 52, operational since October 2025, is the foundation for Intel's 2026–2028 product roadmap, capable of more than 10,000 18A wafer starts per week. Fab 62 (18A-capable, expected ~2028) remains unassigned and serves as a hedge. Ohio One is Intel's most problematic project: originally targeting 2025, now scheduled 2030–2031 (Mod 1) and 2032 (Mod 2), with Intel having spent ~$5B to date. Leixlip (Ireland) returned fully to Intel ownership in April 2026 after the Apollo buyback. Magdeburg (Germany) and Wroclaw (Poland) were cancelled in July 2025.

The gating factor remains customers. Intel has two prospective 14A customers evaluating test chips, but neither has committed to volume. Without confirmed demand, Ohio projects face further delays; with demand, Intel could accelerate 14A ramp beyond the 2029 target. The $28B Ohio facility has space for up to eight fabs, providing flexibility. Bechtel (lead contractor) posted new construction job openings in January, signaling preparation work, but construction start hinges on customer signals.

For architects planning post-2028 AI buildouts, this bifurcation matters: Arizona 18A and Fab 62 offer near-term (2027–2028) U.S.-based capacity; Ohio 14A is contingent on 2026 customer wins. CHIPS Act tax credits expire for projects breaking ground after December 31, 2026. If Intel fails to secure 14A commitments by late 2026, Ohio ramp will slip further, potentially leaving TSMC as the sole high-volume 14A foundry through 2029, constraining supply and regional diversification.
