The U.S. economy continues to expand, but international trade is weighing on headline growth. Atlas Analytics forecasts that real U.S. GDP grew at a 1.5% annualized rate in the third quarter of 2026, down from 2.2% in Q2 and 2.5% in Q1.
Our latest forecast suggests that underlying domestic economic activity remains relatively healthy. However, a widening trade deficit is expected to subtract substantially from headline GDP growth.
This forecast follows two consecutive quarters in which Atlas’s satellite-based GDP estimates came remarkably close to the Bureau of Economic Analysis (BEA) figures.
Our Q3 2026 Forecast: 1.5% Growth
Atlas Analytics’ final estimate for Q3 2026 is 1.5% annualized real GDP growth, with three principal components:
Core GDP: +2.6 percentage points. Private consumption, fixed investment, and government expenditures continue to support economic growth.
Private inventories: +0.5 percentage points. Inventory accumulation is expected to make a modest positive contribution.
Net exports: −1.5 percentage points. A widening trade deficit is expected to significantly offset domestic economic activity.
Together, these components produce our headline forecast of 1.5%.
The distinction between headline GDP and underlying domestic activity is particularly important this quarter.
Our forecast suggests that the U.S. economy is growing more strongly domestically than the headline figure implies. However, rising imports relative to exports are expected to weigh heavily on measured GDP.
Recent trade data reinforce this interpretation. The U.S. trade deficit widened sharply in August, with imports reaching record levels amid continued demand for industrial supplies, capital equipment, and technology-related investment.
In other words, weaker headline GDP growth does not necessarily indicate a comparable deterioration in domestic demand.
Two Consecutive Quarters of Accurate Forecasting
Our Q3 forecast builds on encouraging results from the first half of 2026.
In Q1, Atlas forecast 2.04% GDP growth, compared with the BEA’s latest estimate of 2.49%.
In Q2, Atlas again forecast 1.95%, compared with the BEA’s latest estimate of 2.22%—a difference of just 0.27 percentage points.
Across these two quarters, our average absolute forecasting error was just 0.36 percentage points.
While two quarters represent a relatively small sample, these results are encouraging evidence of the potential for satellite-based economic forecasting.
Our objective is not simply to replicate traditional economic forecasts. It is to develop an independent perspective on economic activity using alternative data sources that can complement conventional government statistics.
Forecasting the Economy from Outer Space
At Atlas Analytics, we combine satellite imagery, geospatial information, and conventional economic data to develop timely estimates of economic activity.
Our approach seeks to identify real-world signals of production, transportation, consumption, and trade—often before these activities are fully reflected in official statistics.
This is particularly valuable when conventional economic indicators are incomplete, delayed, or subject to substantial revisions.
The third quarter illustrates why examining the individual components of GDP matters. Our models suggest that domestic demand continues to expand, even as international trade reduces the overall growth rate.
What Comes Next?
The BEA is scheduled to release its advance estimate of Q3 2026 GDP on October 29, 2026.
Our final forecast of 1.5% will provide another opportunity to evaluate how well our satellite-based approach anticipates official economic statistics.
Regardless of the outcome, our goal remains the same: to make economic forecasting more timely, transparent, and grounded in observable economic activity.
Thank you for following Atlas Analytics as we continue developing a new approach to understanding the economy—from outer space.
