US election prediction markets turn political uncertainty into live market prices. Instead of waiting for polls, pundit models, or campaign narratives to catch up, traders can see how platforms such as Kalshi, Polymarket, and PredictIt are pricing major election outcomes in real time.
This page tracks the most important US election prediction markets for 2026 and 2028, including congressional control, presidential odds, swing-state markets, platform differences, and what the prices actually mean.
Market prices are snapshots from publication and may change quickly. Legal availability can vary by platform, market type, and user location. This page is for informational purposes only and is not financial, legal, or political advice.
US Election Prediction Markets: What the Prices Are Saying
Election markets are currently telling two different stories: 2026 congressional control is the near-term liquidity driver, while 2028 presidential markets are already active because both major-party fields remain unusually open.
What Are US Election Prediction Markets?
US election prediction markets are platforms where users trade contracts tied to political outcomes. A contract might ask which party will control the House after the 2026 midterms, who will win a Senate race, or which candidate will win a party nomination.
The important point is that the price acts like a probability signal. If a contract trades around 63 cents, the market is broadly pricing that outcome near 63%. That does not mean the outcome is locked in. It means traders, using the information available at that moment, are assigning it that level of likelihood.
That is what makes election markets useful. Polls update slowly, pundit models can lag, and campaign narratives can become stale. Market prices move when traders respond to new information, including polling shifts, candidate announcements, legal rulings, fundraising data, debates, economic news, and turnout signals.
How We Selected These Election Markets
We prioritized markets with visible liquidity, clear contract terms, and relevance to major US election outcomes. Where multiple platforms listed similar outcomes, we compared price direction, market depth, and platform access rather than treating one platform as automatically authoritative.
- Liquidity matters: A thin market can move sharply without much information behind it.
- Platform audience matters: Kalshi and PredictIt lean more US-focused, while Polymarket has historically drawn a broader global audience.
- Timing matters: Early 2028 prices are useful sentiment signals, but they are less stable than near-term 2026 markets.
Latest Election Market Snapshot
The current election market picture is split between two timelines. The 2026 midterms are where the near-term action is concentrated, especially in House control, Senate control, and a handful of key Senate races. The 2028 presidential race is already active, but those markets should be read more carefully because the field is still unsettled.
The clearest short-term takeaway is that congressional control markets have moved sharply from earlier assumptions. Republicans retaining control of Congress looked stronger months ago, but traders are now pricing the House as leaning Democratic and the Senate as much closer to a toss-up.
The longer-term takeaway is that the 2028 presidential market is unusually open. With Donald Trump constitutionally barred from running again, both parties are facing more uncertainty than they did during the 2024 cycle. That uncertainty is exactly the kind of environment where prediction markets become active early.
A contract trading at 63% does not mean an outcome is inevitable. It means the market is pricing that outcome as likely based on the information available right now.
2026 Congressional Control Markets
Congressional control is the most important near-term category for US election prediction markets. The House and Senate determine how much governing power the next administration has, and the midterm cycle gives traders a clear set of outcomes to price well before the 2028 presidential field is settled.
The House market is easier to understand than the Senate market. Republicans currently hold a narrow majority, and midterm elections have historically punished the president’s party. That creates structural pressure before you even get into individual districts, candidate quality, fundraising, or approval ratings.
The Senate is more complicated. Control depends less on the national mood alone and more on the exact state map. A party can have a favorable national environment and still run into trouble if the competitive seats are concentrated in difficult states.
For readers new to these markets, the best way to interpret congressional control prices is not to treat them as predictions carved in stone. Treat them as live snapshots of how traders are balancing the national environment, seat math, candidate strength, and incoming information.
2028 Presidential Election Markets
The 2028 presidential market is already drawing attention because it starts from an unusually open position. The Republican field no longer has Trump as an eligible candidate, and the Democratic field has no single dominant successor. That creates early trading activity even before primary voting begins.
At the party level, Democrats were priced as favorites in the 2028 White House market at publication, with Republicans trailing. That number is useful as a broad sentiment gauge, but it is still early enough that a major candidate announcement, economic shift, foreign policy event, or polling change could move the market quickly.
The candidate-level markets are even more fragile. Early presidential contracts often reflect name recognition, media visibility, donor speculation, and activist energy as much as actual primary strength. That does not make them useless, but it does mean they should be read differently from a late-cycle general election market.
Republican Nomination Market
The Republican nomination market has centered on JD Vance as the early frontrunner, but the market has not treated him as inevitable. His price has moved down from earlier highs, suggesting traders still see meaningful room for another candidate to consolidate support.
Marco Rubio has also drawn market attention because of his national profile and foreign policy visibility. Ron DeSantis, Tucker Carlson, and other potential candidates remain on the board, but none has clearly reshaped the market at publication.
The key point is that the Republican market is not simply asking who has the most attention today. It is asking who can build a primary coalition, survive scrutiny, attract donors, perform in early states, and win over voters in a post-Trump nomination cycle.
Democratic Nomination Market
The Democratic nomination market is wider and less settled. Gavin Newsom has been one of the most visible early names because of his national profile, media presence, and positioning against Republicans. Alexandria Ocasio-Cortez, Jon Ossoff, Kamala Harris, and other Democrats have also appeared in market discussion, but the field remains fluid.
That fluidity is exactly why the market is useful. A candidate can move several points on a viral speech, a strong early-state signal, a donor report, or a major endorsement. But those moves should not be confused with settled primary strength this far out.
For 2028 presidential markets, the most responsible reading is simple: the prices are useful as a live sentiment board, but they are not yet a stable forecast.
Key Senate and Swing-State Markets
State-level election markets are useful because they show how national probability breaks down across the map. They can also reveal where traders disagree with public polling averages, ratings from election forecasters, or the broader national narrative.
For 2026, the most useful state-level markets are Senate races. For 2028, swing-state presidential markets will become more useful once the nominees are clearer and liquidity improves.
| Race | Why It Matters | Market Read | How to Interpret It |
|---|---|---|---|
| Georgia Senate | Jon Ossoff is defending a seat in a state that remains central to Senate control math. | Democratic advantage at publication | Markets may price incumbency more heavily than public toss-up ratings, but this remains a race to monitor closely. |
| Maine Senate | Susan Collins gives Democrats a high-profile Republican-held target in a state with split-ticket history. | Democratic pressure | The market can move sharply depending on the Democratic nominee, national environment, and Collins’ approval profile. |
| North Carolina Senate | An open seat creates one of the clearest pickup opportunities on the board. | Competitive | Open seats usually invite more volatility because candidate quality and fundraising matter more as the race develops. |
| Michigan Senate | An open seat in a presidential battleground state makes this one of the most important races on the map. | Lean Democratic at publication | Michigan is likely to track both state-level fundamentals and the broader national midterm environment. |
| Texas Senate | Republican primary dynamics can matter as much as the general election in a state that remains red but increasingly watched. | Republican favored | The general-election market may stay Republican-leaning, while the primary market can carry more actionable movement. |
The most important thing with state-level markets is liquidity. A state market with thin trading should not be treated the same way as a high-volume national market. If two platforms price the same race differently, the first question should be whether one market has significantly more volume, tighter spreads, or clearer participation.
For 2028 swing states, the usual map still matters: Pennsylvania, Michigan, Wisconsin, Arizona, Georgia, Nevada, and North Carolina. But those markets will not become fully informative until the presidential nominees are clearer and more traders enter the contracts.
Kalshi vs Polymarket vs PredictIt for Election Markets
You do not have to look at only one election prediction market platform. In fact, comparing platforms is often the point. Price gaps between Kalshi, Polymarket, and PredictIt can tell you whether traders are seeing the same race differently, whether one platform has deeper liquidity, or whether access rules are shaping the market.
| Platform | Access & Currency | Election Market Depth | Best Use Case |
|---|---|---|---|
| Kalshi CFTC-regulated exchange | US-focused platform using USD. Availability can vary by state, user eligibility, and contract type. | Strong and growing political-market coverage, especially for congressional control, nominations, and major US races. | The clearest regulated route for many US users who want election-related event contracts on a CFTC-regulated exchange. |
| Polymarket Crypto / global liquidity | Historically global and crypto-based. US access has been restricted on the global platform, with a regulated US route developing separately. | Often the deepest global liquidity for major political markets, especially high-profile presidential and international outcomes. | Best for comparing global sentiment and liquidity, but US users should understand access rules before relying on it. |
| PredictIt Research-market framework | US-accessible political market operating under a CFTC no-action/research-market framework. | Narrower than Kalshi or Polymarket, but still useful for niche political contracts and sentiment tracking. | Best as a secondary signal for political specialists, especially when comparing niche markets or appointment-style contracts. |
The most useful comparison is not simply which platform has the most markets. It is which platform has the most reliable price for the specific question you care about. A highly liquid Kalshi Senate market may be more informative than a thin Polymarket state market. A niche PredictIt contract may still be useful if it attracts politically informed traders.
Are Election Prediction Markets Legal in the US?
The legal picture for election prediction markets changed significantly after Kalshi’s court fight with the CFTC. In 2024, Kalshi challenged the CFTC’s attempt to block its congressional control contracts, and the D.C. Circuit denied the CFTC’s emergency stay request. You can read the court document here.
For practical purposes, Kalshi is the clearest regulated option for many US users because it operates as a CFTC-regulated exchange. That does not mean every user in every state can trade every type of contract without restriction. Availability can still depend on the platform, the market category, state rules, and user eligibility.
Polymarket has historically been unavailable to US users on its global platform, but it has taken steps toward a regulated US return. Polymarket received CFTC clearance tied to its US relaunch plans after acquiring a CFTC-licensed derivatives exchange and clearinghouse.
PredictIt should be described differently. It is not the same type of platform as Kalshi. PredictIt has operated under a CFTC no-action/research-market framework connected to Victoria University of Wellington, with the CFTC issuing amended no-action language in 2025. The CFTC letter is available here.
Bottom line: Election prediction markets are not all the same legally. Kalshi is the clearest regulated US exchange route, Polymarket’s US access is developing separately from its global platform, and PredictIt operates under a research-market/no-action framework.

How to Read Election Market Prices
The easiest mistake is to treat election market prices like final predictions. They are better understood as live probability estimates. A 63% price means the market thinks the outcome is more likely than not, but it also means there is still meaningful room for the other side.
Market prices can move for good reasons, such as a major poll, fundraising report, court decision, primary result, debate performance, or candidate announcement. They can also move for weaker reasons, such as thin liquidity, temporary hype, or one-sided trading during a quiet news cycle.
That is why volume matters. A market with millions traded usually gives you more information than a market with only small activity. The same goes for spreads. A tight spread between buy and sell prices usually signals a healthier market than a thin contract where one trade can move the price several points.
Platform disagreement is also useful. If Kalshi prices a race at 55% and Polymarket prices a similar outcome at 65%, that gap could point to a real difference in trader base, liquidity, market rules, or information. It is a reason to investigate, not an automatic reason to assume one price is wrong.
Best Way to Use Election Prediction Markets
The best use of election prediction markets is not blindly following the headline price. The best use is tracking how and why prices move.
For 2026, that means watching congressional control, competitive Senate races, candidate quality, approval ratings, fundraising, and state-level polling. For 2028, it means treating presidential markets as early sentiment signals until the field becomes clearer.
If you are comparing platforms, start with the same question on more than one market. Look at price, volume, spread, contract rules, and who can access the platform. The strongest signal usually comes when multiple platforms with meaningful liquidity point in the same direction.
Election Prediction Markets FAQ
An election prediction market is a trading platform where prices are tied to political outcomes, such as which party will control Congress or who will win a presidential nomination. The price acts like a live probability estimate that can change as new information enters the market.
Election prediction markets can be useful, but they are not perfect. They often react faster than polls or pundit models, but they can still be distorted by low liquidity, platform-specific trader bases, contract rules, or sudden news events.
A 63% price means the market is pricing that outcome as likely, but not certain. It does not mean the race is over. It means traders currently believe the outcome has roughly that level of probability based on available information.
Kalshi is the clearest regulated exchange route for many US users. Polymarket has historically offered deep global liquidity but has had US-access restrictions on its global platform. PredictIt remains useful for niche political contracts but is more limited than the larger platforms.
It depends on the platform, market type, and user location. Kalshi operates as a CFTC-regulated exchange, Polymarket’s US route is developing separately from its global platform, and PredictIt operates under a research-market/no-action framework. Users should check current platform rules and local restrictions before participating.
Kalshi and Polymarket can show different prices because their trader bases, access rules, liquidity, contract details, and market depth are not identical. A price gap can be a useful signal, but it should be evaluated alongside volume and contract rules.
