Prediction markets have shifted dramatically in favour of Democrats as the midterm elections enter their final stage. According to Kalshi markets, Democrats now have a 64 per cent chance of controlling the Senate and a 91 per cent chance of controlling the House—a significant reversal from earlier in the campaign when Republicans held the advantage in Senate predictions. This change comes despite Republicans currently holding 53 Senate seats compared with Democrats' 47, indicating substantial market-driven expectations of Democratic gains.

The article outlines numerous Senate races with varying levels of competitiveness. The Texas contest between Democrat James Talarico and Trump-endorsed Republican Ken Paxton is currently the most heavily traded individual race, with nearly $14 million in market volume and Talarico at 58 per cent; Iowa is the other major toss-up race. Former Senator Sherrod Brown leads Republican Jon Husted in Ohio (60 per cent to 40 per cent), whilst in other competitive races, Democrat Roy Cooper leads in North Carolina (94 per cent to 6 per cent), Democrat Troy Jackson leads Susan Collins in Maine (71 per cent to 29 per cent), and Democrat Abdul El-Sayed leads Mike Rogers in Michigan (71 per cent to 29 per cent). Republican-held seats in Kansas and Nebraska remain favourable to incumbents, whilst Democrat Chris Pappas leads in New Hampshire with 85 per cent.
