4-bullet brief | narrative

Kalshi prices a Republican win in FL-25 at just 21%, a notably weak reading in a Florida district.
69% of all-time contract volume arrived in a single 24h window, signaling sudden market interest.
FL-25 pricing implies Democrats are favored roughly 4-to-1; new candidate or polling data may have triggered attention.
Resolves on certified 2026 midterm results for Florida's 25th Congressional District.
