Do you wait for the third GDP estimate before you trust the number?

The first GDP estimate for the third quarter of 2026 put real output up at an annual rate of 3.4%. The Bureau of Economic Analysis publishes three estimates for each quarter, and the advance one is the first, based on partial data (BEA: GDP, third quarter 2026, advance estimate). It is labelled advance because it can be revised as more information comes in, and the revisions can be large enough to change the story.

For a new reader the obvious question is which estimate to trust. The answer depends on what you are deciding. A trade that lasts an hour responds to the headline number. A view that lasts months benefits from waiting for the later estimates. US GDP grew 3.4% in Q3 2026 explains what the advance figure covers and what it does not, and how to use an economic calendar shows where the revision dates are listed.

We would like to hear your habit:

• Do you trade the advance estimate, or wait for the second and third?
• How big does a revision have to be before it changes your plan?
• Do you check what the revision was driven by, or only the headline figure?
• Which of your past trades would have looked different on a revised GDP number?
