Open any cable network the week before an election and you get the same thing: a big touchscreen, a lot of red and blue, and a person telling you which races are safe, which lean, and which are up for grabs. It looks authoritative. It is, underneath, a forecast. Someone read the polls, weighed the fundamentals, and made a call.
We wanted a map that did not ask anyone to guess. So we built one that takes its colors from prediction markets instead. It is live now on the 2026 midterm map, and here is how it works and why we think it is a better way to read the race.
Two maps, every seat
There are two maps. The first is the Senate: every seat on the November 2026 ballot, which comes to 35 races, the 33 regularly scheduled Class 2 seats plus special elections in Ohio and Florida. The second is the House: all 435 districts, the whole chamber, up at once.
Each race is colored by its live win odds. Not by a rating a network assigned, but by the price traders are paying right now on the question of who wins. A seat that is a genuine coin flip looks like one. A seat that is not moves toward one side and stays there until the money says otherwise.
Where the odds come from
The numbers come from Kalshi and Polymarket, the two largest prediction market exchanges. On both, people buy and sell contracts that pay out based on who actually wins. If a trader thinks a candidate is underpriced, they buy, and the price moves. The price, in other words, is a probability that a lot of people are willing to bet on with their own money.
For every race we blend both venues rather than picking one. The blend is weighted by trading volume, so the deeper, more liquid market counts for more and a thin, jumpy market counts for less. You are not looking at one exchange's quirks. You are looking at the combined view of both, tilted toward wherever the real volume is. The maps pull fresh prices every hour, and the balance of power bars recompute themselves as the odds move.
The balance of power, live
Above each map is a seat bar that tracks control of the chamber in real time. The Senate needs 51 seats for a majority, so the bar combines the 35 races on the ballot with the 65 senators who are not up this cycle and carry over. The House needs 218, and every one of its 435 seats is in play. As prices shift across the day, the bars shift with them. There is no need to do the arithmetic yourself; the map is always showing you where control sits at this moment.
Click into any race
The map is the overview. The detail lives one click away. Every single race, all 470 of them, has its own page. Click a state or a district and you land on it: the blended odds, the breakdown of how Kalshi and Polymarket each price that specific contest, the volumes behind each, and a link straight to the underlying market if you want to trade the view yourself.
That means you can go from a national picture to a single House district in Texas and back without ever leaving the site, and every one of those race pages is priced by the same live, real-money engine as the map on top.
Why markets, not pundits
A pundit's rating is a snapshot of one person's judgment, updated when they get around to it. A market price is the judgment of everyone in the market at once, updated the instant news breaks, enforced by the fact that being wrong costs money. When a candidate stumbles, you do not wait for a network to re-rate the seat. The price has already moved, because someone had money on the old number and rushed to adjust.
None of that makes markets oracles. Odds are probabilities, not promises. A seat priced at 50 percent is a coin flip, and even a heavy favorite loses sometimes, that is what a probability means. But markets have a strong track record on elections, and they have one honest quality that a rating does not: the people setting the price have something to lose if they are wrong. That tends to keep them disciplined.
Go look
The map is live and it moves. Between now and November it will tell you, hour by hour, where the money thinks the Senate and the House are heading, without a single analyst leaning on a touchscreen to tell you what to think.
