Election Night

Polymarket is the world’s largest prediction market, where users trade on the real-world outcomes of events across Election Night and many other topics. Prices are quoted from 0 to 100 cents and reflect the implied probability that an event will occur. Because traders put real money behind their views, Polymarket odds represent a real-time, skin-in-the-game consensus, often referred to as the "wisdom of the crowd."

A Election Night prediction market lets users trade Yes or No shares on a specific question tied to Election Night-related events, such as "Which Senate races will be within 5%?". Each share pays out $1 if the outcome resolves in its favor, and $0 if it does not. The current share price, for example, 75% on "Texas", reflects the market’s implied probability for that outcome at any given moment.

The Election Night category hosts 2K markets covering a wide range of subjects. Popular subcategories include House Elections, Midterm MOV, and Senate Elections, each with its own dedicated page showing live odds, trading volume, and active markets. You can browse the full list of Election Night subcategories from the left-side navigation on the Election Night page.

Every Election Night market on Polymarket has outcomes priced between 0¢ and 100¢. That price is the implied probability of the outcome occurring. For example, if "Texas" is trading at 75% in "Which Senate races will be within 5%?", traders are collectively pricing in roughly that probability. Prices update continuously as new information, data releases, and events move trader sentiment.

Activity is constantly shifting, but you can sort the page by 24-hour volume to see where trading is concentrated. Currently, "South Carolina Senate Election: Greenville County Winner" is among the most actively traded markets on the Election Night page, alongside other high-volume markets like "Which Senate races will be within 5%?" and "Which Senate races will be within 1%?".

Each Election Night market has a clearly defined resolution source and criteria published on the market page. When the event concludes, for example, when a result is officially reported, a deadline passes, or an authoritative source confirms the outcome, the market resolves and winning shares pay out $1 each. Markets in categories such as Elections, Economy, and Geopolitics typically rely on official government, regulatory, or primary-source reporting for resolution.

Election Night markets respond in real time to news, announcements, data releases, and policy shifts. A single development, such as a new poll, economic indicator, court ruling, or geopolitical event, can materially change the implied probability of an outcome. Looking at markets like "Which Senate races will be within 5%?", price movements reflect traders continuously updating their views as fresh information arrives.

Polymarket currently lists 2K markets in the Election Night category, with 18 of those in Election Night alone. The left-side navigation shows live market counts for every subcategory, including House Elections, Midterm MOV, and Senate Elections, so you can quickly see where coverage is deepest.

Yes. Most Election Night markets are designed to let users trade well ahead of the underlying event, from short-horizon weekly markets to long-dated markets covering outcomes months or years away. Examples currently listed include "Which Senate races will be within 5%?" and "Which Senate races will be within 1%?", which let traders take positions as new information emerges over the life of the market.

Prediction markets and traditional forecasts, such as polls, models, or analyst estimates, are complementary tools. Because Polymarket traders are risking real capital, Election Night odds aggregate many participants’ information and incentives into a single probability, a mechanism that has historically tracked real-world outcomes closely in domains like Elections, Economy, and Geopolitics. That said, no market is a guarantee; odds represent trader consensus at a point in time, not a prediction of what will happen.

You can browse the Election Night page to see active markets, open any market such as "Which Senate races will be within 5%?" to view its order book and full rules, and then trade Yes or No shares once your account is funded. The left-side navigation makes it easy to drill into subcategories like House Elections or Midterm MOV to focus on the topics you follow most closely.

Election Night markets are driven by the same catalysts that move the underlying real-world story: official announcements, scheduled events and deadlines, data and reporting, and major news. For a market like "Which Senate races will be within 5%?", watch for upcoming dates, related Election Night releases, and shifts in the broader House Elections and Midterm MOV markets, all of which can change the implied probability traders assign to each outcome.

Every market card on Election Night and Election Night pages displays the current implied probability for each outcome along with 24-hour or cumulative trading volume.
