Where the World's Chip Capacity Is Actually Going, and How Fast

Start with the number everybody quotes. Global semiconductor manufacturing equipment sales are forecast at $165.9 billion in 2026, per SEMI's Mid-Year Total Semiconductor Equipment Forecast, published 14 July 2026. Wafer fab equipment, the part that actually makes wafers, accounts for $143.9 billion of that, a 23.1% increase on 2025. Axis Intelligence Research, which tracks these forecasts, puts the industry's own capital plans 17% above where they first stood for the year, on a metric it calls the Capex Revision Index.

The revisions tell their own story. SEMI's 2026 total-equipment figure has been through several editions. The first eighteen months barely moved. The last seven added $20.9 billion.

"The useful question for anyone sizing tool demand is not what the 2029 number says, it is how much the 2026 number has already moved while 2026 was in progress," Axis Intelligence's Sophie Winslow wrote in the August 2026 report.

Leading edge grows fast, its share grows slowly

Here is where the popular version of the story goes wrong. Absolute capacity at the most advanced nodes is climbing quickly: SEMI's 300mm Fab Outlook counts 850,000 wafers per month at 7nm and below in 2024, 982,000 in 2025, 1.16 million in 2026, and 1.4 million in 2028. Sub-2nm capacity moves from under 200,000 wafers per month in 2025 to over 500,000 in 2028. Those are real numbers. They are also numerators.

The denominator is growing too. Axis Intelligence calculates that 7nm-and-below capacity will be about 12.6% of the world's installed 300mm capacity in 2028, up from roughly 10% in 2024. In other words, even at the end of the decade, roughly seven of every eight 300mm wafers of installed capacity will still run at nodes above 7nm. Total 300mm capacity reaches a record 11.1 million wafers per month in 2028, on a stated 7% compound annual growth rate from the end of 2024.

The equipment spending curve keeps climbing. SEMI's April 2026 300mm Fab Outlook puts front-end spending in 300mm fabs at $133 billion in 2026, $151 billion in 2027, $155 billion in 2028 and $172 billion in 2029. That edition tracks 404 facilities and lines worldwide, with 198 updates and nine new fabs or lines added since December 2025. Extending the revision method forward, the 2027 forecast has moved further than 2026's.

National plans, national numbers

Governments are writing part of this bill. The U.S. Department of Commerce had disbursed $13.1 billion of $31.2 billion in CHIPS direct funding awards as of 30 April 2026, an execution rate of 41.99%, according to GAO report GAO-26-109121. The Semiconductor Industry Association, with Boston Consulting Group, projected in May 2024 that the United States would triple domestic fab capacity from 2022 to 2032, a 203% increase, and grow its share of world capacity from 10% to 14%. The same report projected the U.S. would hold 28% of global capex from 2024 to 2032, second to Taiwan's 31%.

Elsewhere the bets are smaller and more specialised. India's government announced on 15 July 2026 a ₹625 billion (about $6.5 billion) Mobile Phone Manufacturing Scheme plus ₹1.28 trillion (around $13.3 billion) for domestic semiconductor manufacturing, expanding a $10 billion chip incentive programme launched in 2021, as TechCrunch reported. Malaysia holds 13% of the global market for chip packaging, assembly and testing, the Malaysian Investment Development Authority said in February 2024, and its second finance minister, Amir Hamzah Azizan, told CNBC in April 2024 that the country was moving up the value chain rather than competing head-on at the leading edge.

The supply chain has a single point of failure that no incentive programme fixes. Spruce Pine, North Carolina, is home to the only ultra-pure quartz mines in the world, operated by Sibelco North America and The Quartz Corp, material used in crucibles for growing silicon ingots. Hurricane Helene brought over two feet of rain to the area in late September 2024, cutting roads and power. Tom's Hardware reported that Sibelco had confirmed a suspension of operations while The Quartz Corp said it was too early to assess the impact. A 2008 fire at the same site disrupted high-purity quartz supply to the world market.

So the capacity build-out is real, expensive and uneven. Equipment billings confirm it quarter by quarter, with SEMI reporting a record $36.55 billion in Q1 2026, up 14% year on year. The harder question is what gets built where, and how much of it is genuinely leading edge.
