Polymarket debuts interactive map for trading on combined 2026 Senate election outcomes

Prediction News reports Polymarket released Polymap, an interactive tool for the 2026 midterm elections that lets users build a Senate map by picking winners in seven competitive races in Alaska, Iowa, Kansas, Maine, Michigan, Ohio and Texas and trade on that specific combination. The tool displays live Senate, House and Governor odds and links to individual trading markets for each contest.

Polymarket has released Polymap, an interactive map for the 2026 midterm elections that connects election forecasts with trading markets, according to Prediction News.

Building a Senate outcome

The tool lets users construct a Senate map by selecting winners in seven competitive races: Alaska, Iowa, Kansas, Maine, Michigan, Ohio and Texas.

Users can then trade on the particular combination of winners they select, Prediction News reports. That makes the assembled Senate map a way to express a forecast across those seven contests, rather than only choosing outcomes race by race.

Tracking individual contests

Polymap also displays live odds for Senate, House and Governor elections. Alongside that overview, it provides links to the individual trading markets for each contest, according to Prediction News.

What it means for prediction markets

  • Combination-based trading: Users can express a specific seven-race Senate forecast through a trade on their selected combination.
  • Separate routes to markets: The map supports both combination-based Senate trading and access to individual contest markets.
  • Broader election monitoring: Live Senate, House and Governor odds bring multiple categories of midterm markets into one interactive tool.
