4-bullet brief | narrative

The Kalshi prediction market prices Republicans winning FL-27 at 63%, a slim majority-bet that reflects genuine competitive uncertainty.
The AP report that redistricting in Florida may not favor Republicans as expected is consistent with the market's refusal to price a safe GOP seat.
At 63%, FL-27 is among the most competitive Florida seats in the prediction market landscape; the companion FL-12 contract on Polymarket sits at only 11% Republican, suggesting district-level variance.
Resolves via Library of Congress; final certified results determine the winner, so any recount scenario could delay settlement.
