AURA-PUI is a daily index of U.S. economic policy uncertainty, built from prediction market prices on Kalshi and Polymarket. It covers five policy domains: monetary, fiscal and regulatory, trade and geopolitical, macroeconomic outcomes, and sector-specific. The index aggregates uncertainty signals from active, policy-relevant contracts into a single daily headline level (base 100, inception April 20, 2024).

Inputs

AURA-PUI draws on binary and multi-outcome contracts from Kalshi and Polymarket. For each contract, the index uses the current price, recent price dynamics, traded volume, and, where available, the quoted bid-ask spread. Contracts are screened for policy relevance and assigned to one of the five domains.

Construction

For each eligible contract, AURA-PUI computes an uncertainty score. Scores are normalized across the basket and weighted to reflect contract size and quote tightness. Concentration rules cap how much any single domain or any single contract can contribute to the headline.

Revisions

v2.6 (June 10, 2026): Layer-2 conditional-uncertainty normalization changed from median-referenced z-scores to a pooled cross-sectional ECDF, removing score saturation; index scaling re-anchored level-neutrally at the cutover; point-in-time daily volume measurement adopted for Polymarket constituents; daily values finalize at T+1. The eligible contract universe was simultaneously restocked (+104 markets ahead of the 2026 midterms), so prints around the cutover date reflect both the methodology revision and the broader universe. Published values dated before the cutover are locked and unaffected.

v2.7 (September 16, 2026): Three construction fixes from an engine audit. The 50% domain concentration cap and the score-proportional per-contract caps are now enforced jointly as a single projection; previously the per-contract step could leave individual weights above their documented caps (13% of published domain-days in the sub-indices, and the headline on days a post-hoc domain re-cap fired), and per-contract enforcement now uses an exact water-fill. Domain persistence activates only when a domain has no live constituents and carries its last value at a decaying weight rather than decaying the value itself. Index scaling re-anchored level-neutrally at the cutover from a trailing-60-day comparison of old and new construction on identical data (headline effect about 2 points, daily correlation 0.98; sub-indices essentially unchanged). Published values dated before the cutover are locked and unaffected; historical cap exceedances remain in the record as published and are disclosed here.

  • Informational use only. AURA-PUI is provided for informational and research purposes. It is not investment advice, not a recommendation to trade any contract, and not a benchmark for any financial product.
  • Independent publisher. Aurelian is not affiliated with Kalshi, Polymarket, or any contract issuer or exchange. Source venues do not endorse, sponsor, or review this index or its methodology.
  • Methodology may evolve. Aurelian reserves the right to refine the index methodology. Material revisions are documented in the methodology paper. Historical levels are not retroactively recomputed under revised methodology.
  • Data quality. Prediction-market liquidity varies; periods of low aggregate liquidity may increase index sensitivity to single contracts. The methodology documents the cap and blending rules that mitigate this.
  • Past performance. AURA-PUI is a measurement, not a tradable instrument. Historical levels do not indicate future levels of policy uncertainty.
