WASHINGTON, November 2, 2026 — U.S. manufacturing activity strengthened in October for a 10th consecutive month, with the Institute for Supply Management’s Purchasing Managers’ Index rising to 55.5 from 54.5 in September. The increase was stronger than economists had expected and was supported by expanding new orders, higher production, and a return to growth in factory inventories, although manufacturers continued to report elevated input prices and slower supplier deliveries.
The ISM manufacturing PMI is a survey-based indicator in which readings above 50 signal that activity is expanding. The October result points to a sector that is growing rather than contracting, but it does not mean every industry or factory is improving. Five of the six largest manufacturing industries covered by ISM reported growth, while others continued to face cost, supply chain, or demand pressures.
Production was the strongest component of the report. The production index rose to 59.0 from 56.7 in September, its highest reading since November 2021. New orders increased to 55.5 from 55.3, extending the period of growth to 10 months. Export orders also remained in expansion territory, while the backlog of orders grew more slowly than in September. Together, the measures suggest that demand is supporting factory output, but the pace and distribution of growth remain uneven.
The employment index eased to 52.4 from 52.7 but stayed above 50, indicating that manufacturing employment was still expanding in the survey. The result is consistent with continued hiring, though the slower reading suggests that job growth is not accelerating at the same pace as production. Survey responses are not a count of jobs added; official employment data will provide a separate measure of hiring across the wider economy.
The prices index fell to 75.2 from 77.9, signalling that the pace of reported input-price increases moderated. The index remained well above 50, however, which means price pressures were still widespread among surveyed manufacturers. ISM said commodities reported as more expensive included electronic components, memory components, semiconductors, steel, copper, diesel, energy, and freight. Some of those inputs are used across the economy, while others are particularly important for data centers, electronics, and industrial equipment.
That mix creates a difficult backdrop for companies trying to expand production. Strong orders can support revenue and capacity utilization, but higher costs for materials, freight, and energy can erode margins if manufacturers cannot pass them on to customers. Companies may also delay investment when prices are volatile or when they cannot predict the cost of equipment and components over a long project timetable.
Supplier deliveries remained slow for an 11th consecutive month, with the index rising slightly to 59.1 from 59.0. In the ISM survey, a reading above 50 on this measure indicates slower deliveries rather than faster performance. Slower delivery times can reflect strong demand, constrained capacity, or logistical difficulties. The index alone does not identify which factor is responsible for every delay, but it indicates that manufacturers are still waiting longer for some inputs.

Inventories returned to expansion, with the index rising to 51.4 from 48.6. That may help manufacturers build buffers against future disruption, although the report also said customers’ inventories remained too low at 41. 6. Low customer inventories can be positive for future production if buyers need to replenish stocks, but they can also leave supply chains vulnerable if deliveries are delayed or prices rise sharply.
New export orders edged up to 51.2 from 50.9, indicating modest growth in overseas demand. Imports increased to 52.9 from 51.0. These measures suggest that international trade flows were expanding, but they do not establish that every export-oriented industry is benefiting equally. Exchange rates, tariffs, shipping costs, and the composition of goods being traded can all influence the experience of individual manufacturers.
Manufacturing accounts for a relatively small share of U.S. employment compared with services, but it remains important for investment, productivity, industrial supply chains, and exports. Strong factory output can support suppliers, logistics providers, and local economies around production hubs. The sector also supplies equipment and components used in infrastructure, construction, transport, energy, and technology, meaning its performance can affect investment plans well beyond factories themselves.
AI demand is helping some industries.
Reuters reported that robust consumer demand and business spending on AI were among the factors supporting the October expansion. Demand for computing equipment and data center components has increased the importance of manufacturing capacity for electronics, semiconductors, electrical systems, and industrial equipment. Those gains can help some suppliers even while other sectors face weaker demand or higher costs.
AI-related demand is not a complete explanation for the manufacturing rebound. ISM’s report showed expansion across several industries, including machinery, computer and electronic products, transportation equipment, and chemicals. The survey also showed that input prices remained high and that delivery times continued to lengthen. The result is a picture of growth alongside capacity and cost pressures, not a simple boom in every factory sector.
The infrastructure required to support AI can also create second-order demand for power equipment, cooling systems, electrical components, and networking hardware. Manufacturers serving those markets may benefit from large data center projects, but they still need to deliver products on time and manage input costs. A strong order book does not guarantee that a supplier can convert every order into profitable revenue if materials are scarce or customer projects are delayed.
Recent investment announcements by large technology companies show why manufacturers are watching the sector. Companies are raising capital and expanding data center infrastructure, but investors are increasingly questioning how quickly that spending will generate returns. If technology firms slow their build-outs, demand for some components could weaken; if spending continues to rise, suppliers may face further pressure to expand capacity and secure materials.
Tariffs and trade-policy uncertainty remain another concern for manufacturers. Changes in import costs can affect raw materials, intermediate components, and finished products, while uncertainty about future policy can make it harder to set prices or commit to long-term capital expenditure. The ISM survey’s qualitative comments point to concern about pricing volatility and supply constraints, though the report does not quantify the effect of each policy on the overall PMI reading.
The relationship between manufacturing activity and inflation is important for monetary policy. A higher PMI suggests that factories are expanding, but the prices index at 75.2 indicates that many firms are still paying more for inputs. If those increases persist and are passed through to consumers, they could complicate the Federal Reserve’s efforts to bring inflation back toward its 2% objective. The ISM report is one survey, not a direct forecast of consumer inflation, and the effect will depend on wages, margins, productivity, and pricing decisions across the economy.

The broader U.S. economy grew at an annualized rate of 3.4% in the third quarter, according to government data reported by Reuters, with domestic demand providing support. That macroeconomic strength helps explain why manufacturing can expand even while some businesses report uncertainty. The relationship is not automatic: factories respond to different customer markets, and the PMI is a diffusion index measuring the breadth of reported change rather than the dollar value of output.
For the Federal Reserve, stronger factory activity may indicate that demand remains resilient, while the prices index suggests that cost pressure has not disappeared. The Fed held its benchmark rate at 3.75% to 4.00% and has said inflation remains elevated. Market expectations for future policy can change as new data arrive, but the October PMI alone does not determine whether rates will rise or fall at the next meeting.
Businesses will be watching whether the expansion continues into November, whether new orders translate into actual production and whether suppliers can reduce delivery delays. A sustained increase in output would support the case that the factory sector has moved beyond its previous contraction, while a reversal in orders or a renewed acceleration in prices could signal fresh strain. The employment index and backlog of orders will also help show whether growth is broadening or becoming more dependent on a few industries.
Investors and policymakers should also distinguish between a manufacturing survey and hard data on industrial production, factory orders, and trade. The ISM report arrives quickly and can provide an early read on conditions, but it is based on responses from supply executives and can be revised in the sense that later months may change the picture. Official production and trade statistics will provide further evidence of whether the survey’s strength is translating into output and sales.
For now, the October reading points to an expanding manufacturing sector with stronger production and steady new orders. The improvement is tempered by elevated prices, slower supplier deliveries, and uneven conditions across industries. The next test will be whether demand remains strong enough to support production without intensifying the cost and supply pressures that can limit the benefits of growth.
