48% — Will US test scores in Reading decline
Leader: Significant decrease at 48% · Kalshi 48% · 3 contracts · $18 volume · medium confidence
Updated 2026-06-26 09:43:07 UTC

Tracks the leading outcome in a winner-take-all prediction market set with 3 outcomes.

Why this matters:
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

Contracts:
- Will US test scores in Reading decline?: Significant decrease — 48¢ Kalshi $11 (weight 64%)
- Will US test scores in Reading decline?: No significant difference — 41¢ Kalshi $6 (weight 36%)
- Will US test scores in Reading decline?: Significant increase — 10¢ Kalshi $0 (weight 0%)

## Methodology

SimpleFunctions aggregates live YES-side prices from Kalshi and Polymarket contracts bound to this question. For binary topics the headline is the liquidity-weighted mid-price (weight = log(1 + 24h volume) × freshness, where freshness is 1.0 if updated <24h, 0.7 if <7d, 0.4 otherwise). For multi-outcome (winner-take-all) topics the headline is the current leader's price — disjoint outcomes are never arithmetically averaged. Snapshots refresh every 5 minutes during market hours.

## SF Signal
