GDP Nowcast Tracker Blend

Several Federal Reserve banks run public GDP nowcasts that update automatically every time a component data point lands, and they routinely disagree with each other by a full percentage point because they weight the inputs differently. Their historical accuracy is measurable. You blend them by past performance rather than treating whichever one got quoted in the press as the truth, and trade growth and recession markets against the blended estimate.

What you need to run it

Scraping of each public nowcast with a stored history of its revisions
Accuracy scoring of each tracker against final GDP prints to set blend weights
Understanding of which release each tracker reacts to, so jumps are anticipated

Where this applies

Markets on Polymarket where gdp nowcast tracker blend is the natural play:

Will Q4 GDP growth exceed 2%?
Will the US economy contract this quarter?
Will GDP growth be revised upward in the second estimate?
