Polymarket Launches 2026 Midterms Hub With Live Odds Map and Balance-of-Power Markets

Polymarket announced on September 16, 2026 the launch of its 2026 Midterms Hub, a dedicated destination for following the U.S. midterm elections across the platform’s live prediction markets. The company said the hub consolidates individual race markets, an interactive electoral map, balance-of-power markets, and a key-races view, with live Election Day results planned alongside market odds when returns come in.

The announcement, distributed via press release, describes the hub as the latest expansion of how users can follow and interpret the information generated by Polymarket’s markets.

What the hub includes

According to Polymarket, the Midterms Hub includes live trading markets for Senate, House, Governor, and local and mayoral races across the 2026 midterms. An interactive map of the country is colored by real-time market odds, and users can zoom from the national picture down to individual states and districts and click into any race to see current prices and probability shifts.

Dedicated balance-of-power markets cover which party will win the House and Senate, which party will hold the most governor seats, and the overall balance of power after November. A separate key-races view highlights the most competitive contests of the cycle.

One announced feature is not yet live: real-time vote counts streamed alongside market odds on election night. The company said live vote status and results “will sit alongside market odds as returns come in” on Election Day, a future capability distinct from the tracking tools available at launch.

“The outlook on elections changes by the day, and sometimes by the hour. A new poll comes out, a candidate has a big debate, something happens on the campaign trail, and expectations change,” said Rob Eskridge, Head of U.S. Government Affairs at Polymarket, in the announcement. “Prediction markets capture all that in real time. The Midterms Hub gives people a simple way to see where the country thinks these races are headed and how that changes between now and Election Day.”

How the markets work

Per Polymarket’s Midterms page, each market lets users trade Yes or No shares on a specific question, such as “Which party will win the House in 2026?” Shares are priced between 0 and 100 cents, with the price representing the market’s implied probability of the outcome at that moment. Each winning share pays out $1 when the market resolves; losing shares pay $0. Prices update continuously through trading activity as new information — polls, debates, data releases, and campaign developments — arrives.

The company said in its announcement that it listed more than 560 markets across its 2026 midterms coverage, spanning Senate, House, gubernatorial, referendum, and balance-of-power outcomes. Notably, the live Midterms page retrieved on September 16, 2026 displayed a higher figure, stating the category hosted 1.2K markets; the two counts come from the company at different points and are not reconciled in the available materials.

Snapshot of live midterms markets

As displayed on polymarket.com on September 16, 2026 — a point-in-time snapshot, not a standing figure — “Which party will win the House in 2026?” showed the Democratic Party at 88% with $11 million in displayed volume, and “Balance of Power: 2026 Midterms” showed Democrats Sweep at 59% with $12 million in displayed volume. “Which party will win the Senate in 2026?” showed the Democratic Party at 59% with $5 million in displayed volume.

Race-level examples displayed at the same time included the Texas Senate race, with James Talarico (D) at 56% and Ken Paxton (R) at 45% on $1 million in displayed volume; the Ohio Senate race, with Sherrod Brown (D) at 56% and Jon Husted (R) at 44% on $354,000 in displayed volume; and the Maine Senate race, with Troy Jackson (D) at 71% and Susan Collins (R) at 31% on $1 million in displayed volume. Polymarket’s own FAQ frames such figures as trader consensus at a point in time, not a guarantee of what will happen.

Access and regulatory background

Trading on polymarket.com is blocked in the United States; the Midterms page directs U.S. users to polymarket.us to trade, offering a view-only mode on the main site. According to the CFTC’s designated contract market registry, QCX LLC, operating under the assumed name Polymarket US, has been a designated contract market since July 9, 2025.

An amended order of designation issued by the CFTC on November 24, 2025 vacated a provision in the original designation order that had barred futures commission merchants from intermediating transactions or carrying customer accounts on the exchange. The amended order, issued in response to the exchange’s petition, permits intermediated trading subject to conditions, including compliance with the Commodity Exchange Act, CFTC regulations, and the exchange’s representations in its petition. The order concerns market structure and intermediation; it does not address the Midterms Hub or any specific product.

Polymarket describes itself as the world’s largest prediction market platform; that characterization is the company’s own and is not independently established in the available materials.
