Overall Performance
The Expansion Index for June 2026 came in at 1.50, representing a 50% year-over-year increase in ideated construction investment compared to June 2025. The reading marks the eleventh consecutive month of growth and ranks among the highest ever recorded for the U.S. Expansion Index.
Note: Ideated means any and all projects in some stage of preconstruction. This includes projects whose groundbreaking date may be many years in the future. All such future projects have no guarantee to either achieving a groundbreaking nor reaching to construction completion.

Select Sector Analysis

Geographic Highlights
Geographic strength matched the breadth seen across construction verticals, with 35 states posting significant expansion in June.
Arizona led the nation, propelled by gains in ideated Industrial, Commercial, and Medical construction. Montana also recorded a strong expansionary reading on the back of Commercial activity, as did North Dakota, where Industrial drove the increase.
Contractions remained rare. Only two states fell below year-ago ideated spending levels, Vermont and Nebraska, both of which had also registered contractionary figures in the prior month.
Note: High Expansion Index readings reflect growth in ideated investment dollars rather than project count, meaning a single large project can significantly impact a state's index, particularly if the state has a smaller construction market.
What It Means for Construction
June's Expansion Index of 1.50 marks the eleventh consecutive month of expansion and lands among the highest readings on record, with ideated construction investment running 50% above year-ago levels.
That strength carried across both category and geography, as all ten verticals posted gains exceeding 10% and 35 states recorded significant expansionary readings.
Headline momentum this broad is encouraging, though turning it into actual work still depends on targeting the right pairing of geography and vertical.
