## Analysis

This market estimates a 63% probability that US reading test scores will decline by 2026. The current pricing reflects heightened concern about educational performance, driven primarily by pandemic-related learning loss recovery patterns and recent state assessment results. The main catalyst for resolving this uncertainty will be the release of 2026 National Assessment of Educational Progress (NAEP) results or comparable state-level standardized testing data, expected in late 2026 or early 2027. The outcome hinges on whether schools have successfully reversed pandemic disruptions or face continued performance degradation.

### Key factors

- Pandemic learning loss recovery trajectory: whether schools have offset 2020-2023 learning setbacks or momentum has stalled
- Recent NAEP and state assessment trend lines from 2024-2025 school year showing month-over-month or year-over-year reading performance direction
- Demographic shifts in test-taking population and composition changes that affect aggregate score comparability
- Teacher workforce stability and retention rates, which correlate with instructional consistency
- Definitional scope: whether decline is measured as absolute score drop, percentage-point change, or performance band migration

## Methodology

Headline is the **leader's price**, not an arithmetic mean — averaging disjoint winner-take-all outcomes is meaningless. Per-outcome prices come from the venue's last-traded mid; cross-venue values are simple means across contracts on each venue.
