4-bullet brief | narrative

Kalshi prices the leading CA-14 special election candidate at 97%, high conviction, small residual risk.
$50K in 24h accounts for 41% of all-time volume, a strong single-session concentration.
California special elections can produce late mail-ballot shifts; the 3% discount reflects that tail risk.
Resolves on California's certified results for the 2026 CA-14 congressional special election.
