Senate seat arithmetic

Republicans hold 53 of 100; 51 is a majority. The other 47 need a net 4.

The aggregate control contract does not identify which individual seats would supply that net gain.

The current race ledger

10 Senate races, then 12 governors, each group by state, A to Z.

12 races have snapshot data but no desk note yet. They still appear in full: Florida governor, North Carolina Senate, Georgia Senate, Nebraska Senate, New Hampshire Senate, Iowa governor, Alaska governor, Michigan governor, Arizona governor, Texas governor, New York governor, Pennsylvania governor.

How this desk reads the two booksThe comparison basis, and today's four irreducible facts

Since the previous edition

Comparable with the 2026-08-18 edition — the first pair this desk can subtract.

Today's four irreducible facts

Each claim keeps the two venues separate.

  1. House control

    Democratic-control contracts:

    Polymarket 87.5%Kalshi 84.5%

  2. Senate control

    Democratic-control contracts:

    Polymarket 51.5%Kalshi 48.5%

    Recorded-span changes: Polymarket -1.0pp; Kalshi -0.5pp. No clear move.

  3. Texas Senate — and 1 more

    The books name different leaders. The books also disagree in Alaska governor.

    Polymarket James Talarico leadsKalshi Ken Paxton leadsPolymarket: Ken Paxton 48.5%James Talarico 51.5%Kalshi: Ken Paxton 52.5%James Talarico 48.5%

  4. Florida governor

    David Jolly has the widest current candidate-side venue gap, 5.0pp.

    Polymarket 17.5%Kalshi 22.5%

Cross-venue coverage

Every race on this board is priced by both books.

Method and scope

  • These are trader-implied market prices, not polls and not POLI forecasts.
  • Polymarket volume is USD notional; Kalshi volume is contracts. They are not comparable, so this page does not combine or weight them.
  • Separately traded candidate contracts are independent and do not have to sum to 100%.
  • This is a dated snapshot observed Aug 19, 6:41 AM CT, not a live feed.
  • This edition contains 22 races from its published snapshots: no polls, no vote counts, and no inferred contests.
  • Edition changes publish only when stable race identity, contest kind, market scope, and venue identity make subtraction safe.
