As of the claim date (2026-08-17), the CNBC source says Democrats had less than a 50% prediction-market chance of sweeping both chambers before early September, so the claim that they were favored then is contradicted.

What was said

… If you haven't been keeping up, Democrats are leading across the country. Even when they put up crazy Marxist socialist, uh, communists, they're leading, and it looks like, uh, if you look at Calshi or Poly market, they are favored again to take both houses, which will be a disaster.

What we found

Contradicts. CNBC (Oct 27) reports that before early September Democrats had less than a 50% chance to sweep both chambers on Kalshi and Polymarket, with odds rising only later.[2]

Context. Reuters (Oct 29) and Polymarket/Kalshi snapshots from late October to Nov 2 put Democrats above 60% to take both chambers, showing the favored position came after the claim date.[1][3][4][5]

Context. None of the sources report market odds for August 17 itself, so the contradiction rests on the CNBC statement about the period before early September.[2]
