SEMI, the semiconductor industry association, forecasts equipment spending on 300mm wafer fabs (plants that process 300-millimeter silicon wafers, the industry's standard large format) will reach $149 billion in 2026. That figure represents 31% growth. The association published the projection in its 300mm Fab Outlook report.

Two numbers anchor the story. First, $149 billion: the expected outlay on tools for 300mm wafer fabrication next year. Second, 31%: the growth rate the forecast implies. Both come from SEMI's own outlook series, which tracks fab equipment spending across the global chip manufacturing base.

What does this change for equipment makers?

A 31% jump in one year is a steep acceleration for a capital-goods market. Tool vendors — the companies that supply deposition, lithography, etch and metrology systems to wafer fabs — read forecasts like this as a demand signal. When fabs commit capital, orders for process equipment follow.

For chipmakers, the number signals continued capacity expansion at the 300mm node. For buyers of semiconductors — automakers, data-center operators, device manufacturers — it points to more supply coming online as those lines install and ramp.

Why the 300mm figure matters

The 300mm wafer is the workhorse of high-volume semiconductor production. Equipment spending on that format tracks the health of mainstream chip manufacturing: logic, memory and the foundry business. A $149 billion annual total, growing at nearly a third year over year, marks the segment as one of the largest capital-spending programs in global manufacturing.

What we don't know yet

The headline figures are firm. The underlying detail — which regions, which device segments, and which quarters carry the growth — sits in the full SEMI report. Watch for those breakdowns before drawing conclusions about individual vendors or fab operators.

The bottom line

SEMI's outlook puts 300mm fab equipment spending at $149 billion for 2026, up 31%. It's a large number moving fast. Equipment suppliers, chipmakers and semiconductor buyers will all price this forecast into their 2026 planning — and the next SEMI revision will show whether the acceleration holds.
