U.S. manufacturing delivered a surprise to start 2026, snapping a historic 26-month contraction streak with a decisive return to expansion in January. Both major purchasing manager indices surged upward, signaling the strongest improvement in factory conditions since 2022. The breakout, however, comes with important caveats; much of the activity appears driven by pre-emptive purchasing ahead of anticipated tariff increases, and underlying demand growth remains modest.
Meanwhile, corporate America continued to pour billions into domestic manufacturing capacity, with January seeing a wave of new factory announcements spanning aerospace, data center infrastructure, critical minerals, and heavy equipment.
A Month in Data
Both major purchasing manager indices moved firmly into expansion territory in January, marking a meaningful shift in momentum for the sector.
The ISM Manufacturing PMI surged to 52.6% in January, up a striking 4.7 percentage points from 47.9% in December. This was the first expansion reading in 12 months, and the highest since 2022, following an extended contraction that stretched back 26 consecutive months before a brief two-month reprieve. New Orders led the charge, jumping 9.7 points to 57.1%, the strongest reading since February 2022. Production climbed to 55.9%, while the Employment Index, though still in contraction at 48.1%, improved meaningfully from December’s 44.8%.
The S&P Global US Manufacturing PMI also rose to 52.4 in January from 51.8 in December, recording the strongest rate of expansion broadly in line with the survey’s long-run average. Output growth was particularly notable, matching the joint-best pace since May 2022. However, S&P Global’s data painted a more nuanced picture than ISM’s: new orders returned to expansion but grew only modestly, and export orders fell for the seventh consecutive month as tariffs and trade uncertainty weighed on international sales.
What the Data Means
The January data tells two stories simultaneously. On the surface, it represents a dramatic reversal, the strongest expansion in years, with new orders and production firing on all cylinders. Beneath the headline numbers, however, there are reasons for caution.
First, the surge was driven in significant part by front-loading behavior. ISM Chair Susan Spence noted that “January is a reorder month after the holidays, and some buying appears to be to get ahead of expected price increases due to ongoing tariff issues.” This pull-forward dynamic, firms stockpiling before tariff-related cost increases hit, inflates current readings but borrows from future demand.
S&P Global’s data reinforced this, showing that production growth significantly outpaced new order growth, resulting in a further accumulation of unsold warehouse inventory. Chief Business Economist Chris Williamson warned that over the past three months, factories have produced more goods than they have sold at a rate not seen since the global financial crisis in early 2009, a pattern he described as “clearly unsustainable.”
Second, price pressures intensified. The ISM Prices Index held at an elevated 59.0%, while S&P Global reported that input cost inflation accelerated from December, with vendors raising charges as a result of tariffs. Manufacturers’ own output prices rose at the fastest pace since last August. This cost environment, coupled with customer resistance to higher prices, creates a demand headwind that could limit the durability of the expansion.
January’s breakout is a welcome signal that the prolonged manufacturing downturn may be ending, but it does not yet constitute a robust recovery. The coming months will reveal whether the expansion can sustain itself once the front-loading effect fades and tariff-driven cost pressures fully materialize.
New Factory and Manufacturing Announcements
January 2026 saw a substantial wave of new manufacturing investments announced across the United States, with projects spanning aerospace and defense, data center infrastructure, critical minerals, healthcare, and heavy equipment. Below are five of the most significant announcements from the month.
Century Aluminum and EGA’s New Aluminum Smelter in Oklahoma
Century Aluminum and Emirates Global Aluminium announced plans to build the first new primary aluminum smelter in the United States in nearly 50 years, located in Inola, Oklahoma. With 750,000 metric tons of annual production capacity, the facility is projected to create approximately 1,000 permanent jobs and 4,000 construction jobs, significantly expanding domestic aluminum output for aerospace, automotive, construction, and defense applications. The project represents a major step toward reducing U.S. dependence on imported primary aluminum.
Corning and Meta’s Up-to-$6 Billion Agreement
Corning Incorporated and Meta Platforms announced a multiyear agreement valued at up to $6 billion, under which Corning will supply advanced optical fiber, cable, and connectivity solutions to support Meta’s U.S. data center buildout. To meet this demand, Corning will expand manufacturing capabilities across its North Carolina operations, including a significant capacity expansion at its optical cable facility in Hickory. The deal underscores the enormous infrastructure demands of the AI era and Corning’s central role as a domestic supplier of data center network hardware.
Atlantic Alumina’s $450 Million Expansion in Louisiana
Atlantic Alumina Company, the only operating alumina refinery in the United States, announced a $450 million strategic partnership with the U.S. government and private investors to expand alumina output and develop the country’s first large-scale primary gallium production circuit at its Gramercy, Louisiana, facility. Gallium is a critical material for semiconductors, defense systems, and energy technologies. The project is expected to sustain more than 500 jobs and strengthen U.S. critical mineral supply chains in a market segment currently dominated by China.
John Deere’s Two New U.S. Facilities
Deere & Company announced plans to open two new facilities, a state-of-the-art parts distribution center near Hebron, Indiana, and a $70 million excavator manufacturing factory in Kernersville, North Carolina. The North Carolina facility will bring production of future-generation excavators, previously built overseas, to the United States. Together, the two projects are expected to create approximately 300 jobs and represent a meaningful reshoring commitment from one of America’s most iconic industrial brands.
Future Outlook
January’s return to expansion offers a cautiously optimistic starting point for 2026, but the path forward is anything but clear. The near-term outlook hinges on whether underlying demand can catch up to the production and inventory levels that front-loading behavior has created. If order growth does not strengthen in the coming months, manufacturers could face a production pullback and potential employment impacts.
Tariff policy remains the dominant wildcard. While some firms are optimistic that reduced import competition will benefit domestic producers over time, the near-term reality is higher input costs, squeezed margins, and customer hesitation.
Longer-term structural trends remain encouraging. The volume and diversity of new factory announcements in January point to sustained capital investment in domestic manufacturing capacity. These projects, many backed by strategic government partnerships, are building the foundation for a more resilient and diversified U.S. industrial base. Falling interest rates and reshoring momentum could provide additional tailwinds as 2026 progresses.
For manufacturing leaders, the message is one of vigilant optimism: celebrate the end of contraction, but plan for volatility. The sector is at an inflection point where smart investment, supply chain diversification, and tariff navigation will separate the companies that thrive from those that merely survive.
