Rick Scott's seat is up. Prediction markets say the GOP holds it — but by how much, and against whom? Live Kalshi and Polymarket prices, plus the full platform breakdown.

Quick answer

Rick Scott's Florida seat is priced as a likely Republican hold, with Democrats roughly 15–25% as of early August 2026. The August 18 primary is the next scheduled repricing event; the general election settles November 3. Kalshi lists the CFTC-regulated USD contract, Polymarket the deeper candidate-level book.

Key takeaways

  • › Republicans are ~75% favored to hold the Florida Senate seat.
  • › Rick Scott is the incumbent; primary challenger risk is priced but small.
  • › Democratic nominee TBD — path to victory requires a top-tier recruit.
  • › Kalshi has the cleanest CFTC-regulated head-to-head USD contracts.
  • › Polymarket has deeper primary and vote-margin liquidity.

The August 18 primary, and what changes after it

Florida votes in 11 days. Two things typically happen in this window: primary contracts get most of their annual volume, and the November head-to-head goes quiet until the nominee is known.

  • Primary-week spreads tighten, so entry costs less in slippage than it does in July.
  • Once the primary settles, the general-election contract reprices immediately on the matchup — a known jump, not a gradual drift.
  • Down-ballot correlation matters: the Senate and governor contracts have moved together all cycle, so holding both is closer to one doubled position than two independent ones.

Dates and certified candidate lists come from the Florida Division of Elections.

The race in a paragraph

Sen. Rick Scott, elected 2018 and re-elected 2024… wait, no — Scott's seat comes up again in 2026 after his 2018 win (six-year term). He has signaled a re-election run. Primary challenges from the right are possible but market-priced as low probability. On the Democratic side, no clear top-tier recruit has emerged as of mid-2026; markets discount any Democrat by 25+ points.

What moves the market

  • Recruitment: A top Democratic recruit (former Rep. Val Demings, or a Florida mayor) would tighten the market by 5–10 points.
  • Presidential coattails: Any 2028 primary drama that hurts the GOP brand can bleed into Senate contracts.
  • Fundraising deadlines: Q3 and Q4 FEC filings historically produce sharp intraday moves.
  • Polling releases: Public polls from Mason-Dixon and USF are treated as high-signal by traders.

Kalshi vs Polymarket for Senate

Kalshi's Senate contracts are CFTC-regulated, settle in USD, and don't require crypto onboarding — the right choice for a straightforward "who wins the seat" bet. Polymarket goes deeper: candidate-specific primary markets, vote-margin markets, and turnout contracts that Kalshi doesn't list. For most Floridians, opening both accounts and trading each platform where it's deepest is the winning move.
