4-bullet brief | narrative

The Polymarket contract on negative GDP growth in 2026 sits at just 3%, meaning the market puts near-zero odds on a full-year contraction.
The Q3 GDP print of 3.4%, above consensus, is consistent with this extreme long-shot pricing; the news and the market are aligned.
Inflation running above 2% complicates the outlook but does not shift the growth picture materially at these probability levels.
Resolves via the UMA oracle; the contract covers the full calendar year 2026, so two more quarterly prints remain before settlement.
