The Big Picture blogger Invictus: IT contribution to US GDP growth reaches 35%, far exceeding the 1990s
Invictus, based on data from the U.S. Bureau of Economic Analysis, compares two expansion periods—1995–1999 and 2024Q4–2026Q3—and finds that the share of GDP growth contributed by information-processing equipment and software rose from approximately 16% to 35%, while contributions from the rest of the economy (excluding IT) fell by about 56%. The author argues this indicates insufficient breadth in growth but explicitly states this is not a prediction of an AI bubble collapse; rather, it points out that the current expansion relies more heavily on a single engine than the 1990s did.
The surface data of the U.S. economy appears robust—real GDP continues to expand at an annualized rate of 3.4%, consumers keep spending, and businesses keep investing. But Invictus, the author behind The Big Picture blog, points out in this analysis that a less conspicuous problem is emerging: the share of recent economic growth coming from information-processing equipment and software is unusually large.
Comparing the five-year expansion period from 1995 to 1999 with the most recent eight quarters ending in September 2026 reveals two very different pictures. In the late 1990s, average annualized real GDP growth was approximately 4.17%; over the latest eight quarters, it was only 2.34%. More noteworthy is the composition of growth: investment in information-processing equipment and software contributed an average of 0.68 percentage points to quarterly annualized growth in the late 1990s, rising to 0.81 percentage points over the most recent eight quarters. In absolute terms, the pull from technology investment is actually stronger now, but the proportion is the issue—in the late 1990s, IT and software accounted for about 16% of total growth, whereas this ratio reached 35% during the period from 2024Q4 to 2026Q3.
Invictus uses a simple thought experiment to highlight this shift: subtracting the contribution of IT and software from total growth. In the late 1990s, the rest of the economy contributed approximately 3.49 percentage points of annualized growth after excluding IT; over the most recent eight quarters, this figure was only 1.53 percentage points, a decline of about 56%. He specifically emphasizes that this does not mean the non-IT economy is contracting, but rather that its contribution to total growth is much smaller than it was in the 1990s.
