⚠ Evidence cap applied: the model proposed 53%, brought back to 30% for lack of sources solid enough to justify the departure from the base rate.
Resolution criterion
Yes if the Bureau of Economic Analysis (BEA) "Gross Domestic Product (Advance Estimate), 3rd Quarter 2026" release, published on or before 31 October 2026, reports real GDP growth (seasonally adjusted annual rate) of 3.5% or higher. Only the advance estimate counts; later revisions are ignored. A reported figure below 3.5%, or no advance estimate published by that date, resolves No.
Verified starting state
The BEA release schedule lists the Q3 2026 GDP advance estimate for 29 October 2026 at 8:30 AM ET. The Atlanta Fed's GDPNow model (a nowcast, not an official probability forecast) stood at 3.6% for Q3 on 15 October 2026, unchanged from the previous week (3.7% on 6 October, 3.6% on 8 October). GDPNow is a reference point only; the advance estimate can differ from it by more than a point.
What pushes it up
- The Atlanta Fed's GDPNow model currently estimates Q3 2026 growth at 3.6%, which is above the 3.5% threshold [1].
- The GDPNow estimate has remained stable, staying between 3.6% and 3.7% throughout the first half of October [1].
What pushes it down
- The margin between the current nowcast (3.6%) and the threshold (3.5%) is only 0.1 percentage points, providing very little room for error [1].
- The BEA advance estimate can differ from the GDPNow model by more than one percentage point, meaning a 3.6% nowcast is not a guarantee of the final result [1].
What would move this number most
The inherent volatility and measurement error between the GDPNow nowcast and the official BEA advance estimate.
