US manufacturing construction spending in December 2026

A precise capital expenditure breakdown for specific years is not available. While a definitive percentage breakdown of total announced capital expenditure (capex) from the CHIPS Act and Inflation Reduction Act for US semiconductor and EV battery facilities in 2024-2025 versus 2026 and beyond cannot be definitively calculated, these legislative initiatives have stimulated approximately $460 billion in private investment for US semiconductor, EV battery, and other clean energy manufacturing ^[1]. The CHIPS Program Office plans to finalize all significant funding decisions by early 2025, with many major proposed projects initiating groundbreakings and early construction during 2024 and 2025 ^[2].

Large-scale facility projects will require multi-year capital expenditure. These manufacturing facilities are multi-year endeavors. For instance, LG Energy Solution's $5.5 billion battery manufacturing complex was well underway by April 2024, with mass production anticipated in the first half of 2026, indicating considerable capex spending in 2024-2025 to enable this production ^[3]. In contrast, projects like Micron's memory fab in New York, which had its groundbreaking in January 2026, suggest the vast majority of its capital expenditure will occur from 2026 onwards ^[4]. Overall, while 2024-2025 are periods of intense initial investment, a significant portion of the announced capex for these long-term facilities will be disbursed in 2026 and subsequent years due to their multi-phase nature.

Industrial construction backlog experienced fluctuations in late 2025 and early 2026. The Associated Builders and Contractors' (ABC) Construction Backlog Indicator (CBI) for the industrial sector demonstrated a varied trend across Q4 2025 and Q1 2026. In the fourth quarter of 2025, the industrial sector's backlog saw a decline, decreasing from 7.1 months in September 2025 ^[1] to 6.8 months by December 2025 ^[2]. Entering the first quarter of 2026, the industrial CBI initially rebounded from 6.9 months in January 2026 ^[4] to 7.7 months in February 2026 ^[3], before falling to 7.0 months in March 2026 ^[5]. This sequence of events indicates a pattern of a late 2025 dip, followed by an early 2026 rebound and subsequent moderation.

Few manufacturing projects met the high-value threshold for analysis. Regarding significant manufacturing projects valued over $500 million, the available data presented limited direct correlation with project delays or cancellations. A $1.5 billion General Dynamics Corp. project, which had faced prior delays, was reported to be progressing as of April 2026 ^[6]. While this project met the specified valuation threshold, its status indicated forward movement rather than a new delay or cancellation. Conversely, a $290 million green hydrogen plant project by Plug Power Inc. was cancelled in March 2026 ^[7]. However, this cancellation falls below the $500 million threshold, thereby limiting its direct relevance to the specified correlation analysis concerning major project changes.

US pharmaceutical construction investment exceeds $370 billion since 2020. This substantial new investment in U.S. pharmaceutical and biotech manufacturing construction is attributed to onshoring efforts and the pursuit of supply chain resilience. Dodge Construction Network anticipates this significant trend will continue, with considerable capital outlays projected throughout 2026 ^[1].

Manufacturing construction data is limited for clean energy and defense. Available reports from Dodge Construction Network do not provide specific aggregate values or projected 2026 spending figures for new manufacturing construction in the clean energy (solar/wind components) or defense industrial base sectors. Although the defense budget for fiscal year 2026 is projected at $152 billion, this figure relates to overall Pentagon spending and not dedicated manufacturing construction investment within the defense industrial base ^[3].

Overall US manufacturing construction spending remains robust through 2026. Total manufacturing construction spending across all sectors in the U.S. is projected to reach approximately $220 billion in 2026, according to Dodge Construction Network estimates. Other forecasts suggest a range of $215-225 billion, indicating continued investment in advanced manufacturing facilities, even if the pace of new project starts moderates compared to previous peak years ^[2].

A potential change in presidential administration and congressional control following the 2024 election could significantly alter the regulatory interpretation, funding disbursement, and tax credit availability for the Inflation Reduction Act (IRA) and the CHIPS Act. Former President Trump has indicated a strong push to "kill" the CHIPS Act and repeal the IRA if re-elected ^[1]. While a full legislative repeal of either act might face challenges, a Republican-controlled Congress, especially with a Republican president, would likely seek to repeal or significantly modify their provisions ^[3].

The IRA's clean energy tax credits face potential Republican targeting. A Republican administration and Congress would likely focus on eliminating these credits, with House Republicans having already introduced bills to achieve this ^[2]. A full repeal could be attempted through budget reconciliation, which requires only 51 votes in the Senate ^[3]. However, the political feasibility of a complete dismantling is complicated by the fact that certain IRA programs, such as the Rural Energy for America Program (REAP), disproportionately benefit Republican congressional districts, potentially creating internal resistance ^[4].

Repealing the CHIPS Act presents unique political obstacles. Former President Trump has explicitly stated his intent to "kill" the $52.7 billion semiconductor chips subsidy law if re-elected ^[1]. While executive action could delay or curtail funding disbursements, a full legislative repeal by Congress might face headwinds. The CHIPS Act initially garnered bipartisan support ^[5], and cutting its funding could be politically challenging for some Republicans due to the substantial manufacturing construction and job creation it has spurred in their districts ^[6]. Despite Trump's stance, congressional Republicans have shown reluctance to quickly follow his push, acknowledging the investments made ^[7].

The U.S. Census Bureau revises initial construction spending estimates ^[1]. The Construction Spending Survey (C30) provides monthly data, including estimates for the manufacturing sector. These figures are first released as "advance estimates" and are subsequently revised as more complete information becomes available from respondents. Typically, revisions apply to the data for the current month and the preceding three months ^[1].

Calculating average revision magnitude and direction is not possible ^[1]. The research lacks the specific historical data needed to determine the average magnitude (e.g., in dollars or percentage points) and direction (e.g., consistently revised up or down) of revisions for the "Value of Construction Put in Place, Manufacturing" over the past 36 months. Without a compiled historical dataset of both advance and final figures for this specific category, computing these averages is unfeasible ^[1].

Analyzing revision patterns during high interest rates is unfeasible ^[1]. Due to the absence of the direct historical revision data for manufacturing construction spending, a statistical analysis to identify patterns during periods of high interest rates cannot be performed. While high interest rates are known to impact overall construction activity, the provided research lacks the specific data required to correlate these economic conditions with the nature of data revisions for manufacturing construction spending ^[1].
