2028 Presidential Election Odds: What Prediction Markets Say Now

TL;DR

• The 2028 presidential election is on November 7, 2028. Prediction markets price it in two layers: who wins each party's nomination, and who wins the presidency.
• Polymarket's 2028 winner market has 54 or more candidate outcomes, each with its own Yes and No price. A price is the market's implied probability, and with that many names the longshots are easy to overpay for.
• These are the longest-dated markets on any platform, so the prices drift with news and with the November 2026 midterms, and a high volume figure does not mean a precise price.
• Compare Polymarket and Kalshi side by side and check the prediction market data behind a number before you quote it.

Searching for 2028 presidential election odds this early? The election is on November 7, 2028, more than two years away, and Polymarket's three biggest 2028 markets have each traded hundreds of millions of dollars.

This guide covers how the winner and nominee markets work, what the 2028 election odds look like on Polymarket and Kalshi, and how to read a price that is this far from resolving.

What Do 2028 Presidential Election Odds Measure?

They measure the chance that a named candidate or party wins, as set by traders. Each outcome trades between $0 and $1, and the price is the market's implied probability. A candidate at $0.10 means the market gives that person a 10% chance.

There are two layers. Nominee markets ask who becomes each party's presidential nominee. Winner markets ask who wins the presidency. Winning the presidency normally runs through a party nomination, so the two layers are linked, and our guide to correlated markets explains how.

The date is fixed by law. Election Day is the Tuesday next after the first Monday in November, every fourth year, under 3 U.S.C. section 21, which makes it November 7, 2028. The Twenty-Second Amendment adds that "No person shall be elected to the office of the President more than twice."

What Does Polymarket Show for the 2028 Election?

Polymarket lists the 2028 markets described here. The "Presidential Election Winner 2028" event is a multi-outcome market with 54 or more candidate outcomes, each with its own Yes and No price. It opened on July 11, 2025 and ends on November 7, 2028.

Polymarket also lists a "Democratic Presidential Nominee 2028" market with 53 or more outcomes and a "Republican Presidential Nominee 2028" market with 43 or more. When I checked on October 26, 2026, total volume was about $719 million on the winner market, $1.3 billion on the Democratic nominee market and $717 million on the Republican nominee market.

Those volume figures are cumulative trading since the markets opened. They are not money riding on the outcome today, which our guide to what volume means explains.

Polymarket's pages carry a notice that trading is blocked in the United States on polymarket.com, with a link to polymarket.us. Our guide to Polymarket in the US covers the split.

What Does Kalshi Show for the 2028 Election?

Kalshi is a CFTC-regulated exchange, and it lists 2028 markets for the presidential winner and for the party that wins the presidency. Right now the market puts the Democratic Party winning the presidency, house, and senate at 58%.

A gap between Kalshi and Polymarket on the same candidate is normal. It does not mean one platform is wrong. Each venue has its own traders, its own liquidity and its own settlement rules, which our piece on why odds disagree explains.

Opinion, Limitless and Predict.Fun round out the five platforms PredictionHero tracks, and each runs its own board. Which 2028 contracts each one lists changes over time, so check every board directly.

What Are JD Vance's 2028 Presidential Odds?

JD Vance, the sitting Vice President, appeared among the leading names on both Polymarket and Kalshi when I checked on October 26, alongside Gavin Newsom and Marco Rubio. The market currently puts a Vance win at 18.5%+1on Polymarket and 19%0 on Kalshi.

Keep the two layers straight. A Vance price in the winner market already includes his chance of winning the Republican nomination. His nomination price should be at least as high as his winner price, since winning the presidency normally requires the nomination first.

Why Do Long-Dated 2028 Odds Drift So Much?

A contract that resolves in two years has a lot of time to change. News, polling, the November 2026 midterms and each candidate's decisions all move it, and our guide to long-dated odds explains why far-off contracts can be slow to reprice and then jump.

The midterms are the next big test. They will tell traders how the electorate is leaning, and our guide to midterm election odds covers those contracts.

A field of 50 or more candidates also invites a familiar distortion. Longshots tend to trade richer than their true chance, which our guide to favorite-longshot bias explains. Read the top few prices and treat the tail with suspicion.

How Should You Read 2028 Odds?

Run through five checks, in this order.

1. Timestamp. A 2028 price is a snapshot. Note when you pulled it and from which platform.
2. Which layer. Winner, party and nominee markets answer different questions. Read the contract's resolution rules before you compare prices.
3. Depth. Check volume and spread alongside the last trade. A thin outcome is closer to a few opinions than a consensus.
4. A second platform. One venue can lag. Two venues that agree are harder to dismiss.
5. The calendar. Two years is a long time. Treat a price as a starting point.

PredictionHero lines up prediction market data from all five platforms on one screen, so you can see the spread on a candidate without opening five tabs.
