2028 Presidential Election Odds: Who Will Be the Next President?

The 2028 presidential election cycle is already actively traded on prediction markets, making it one of the most liquid political events in the world. Unlike traditional polls - which measure stated preferences at a single point in time - prediction markets reflect what traders are willing to risk real money on. When you see a candidate priced at 25¢ on Kalshi, the market is collectively assigning roughly a 25% probability to that candidate winning the presidency. Prices update continuously as new information enters the market: polling data, economic indicators, political news, and large trades from institutional participants.

Three main platforms carry 2028 U.S. presidential election contracts. Kalshi is a CFTC-regulated exchange based in the U.S. with the deepest liquidity on political event markets and accepts USD deposits directly - making it the most accessible for American traders. Polymarket operates on the Polygon blockchain and allows significantly higher position sizes using USDC stablecoin, giving it global participation and often faster price discovery. PredictIt, which operates under a CFTC no-action letter, caps individual positions at $850 per contract but remains popular for its accessibility and established user base.

Because each platform has different participants, fee structures, and position limits, prices for the same candidate often diverge. A 3–6% spread between Kalshi and Polymarket on the same outcome is not unusual, creating arbitrage opportunities for traders who hold accounts on multiple platforms. Prediction HuntPrediction.com's cross-platform comparison makes these discrepancies visible in real time.

Next President Odds: Who Is Favored to Win the Presidency?

"Next president odds" and "2028 presidential election odds" describe the same set of contracts: the next occupant of the White House is decided by the November 2028 general election, and every platform tracked on this page settles its market on that result. The live table above is the fastest way to read the field - candidates are ranked by their cross-platform average implied probability, so the order reflects the market consensus rather than any single exchange's book.

Two things are worth watching when you read presidential odds. First, the favorite's price this far from election day is a weak signal historically - front-runners three years out have frequently failed to win their own party's nomination, and the market prices that uncertainty by keeping the leader well under 50%. Second, the gap between the top candidate and the rest of the field matters more than the absolute number: a leader at 20% in a field where second place sits at 16% is a genuinely open race, while a leader at 40% against 8% signals the market has largely made up its mind.

Polymarket 2028 Election Odds

Polymarket lists the 2028 race as a multi-candidate winner market where each candidate trades as its own share priced between 0 and 1 USDC - a share at 0.20 implies a 20% chance. Because Polymarket has no meaningful position cap and draws global participation, it usually carries the largest open interest on this race and tends to reprice first on breaking political news.

Kalshi 2028 Election Odds

Kalshi lists the equivalent contract as a CFTC-regulated event future settling at $1.00, quoted in cents, with USD deposits and no crypto step. That regulatory status is why Kalshi is typically the first stop for U.S.-based traders, and its order book is the deepest of any domestically accessible venue on political markets.

The two venues rarely agree exactly. A candidate priced at 20¢ on Kalshi and 0.23 on Polymarket is a 3-point disagreement - small enough to be explained by fees and participant mix, but large enough that the cheaper side is the better entry. The platform columns in the table above put those quotes side by side; the arbitrage scanner flags the cases where the spread is wide enough to lock in a return on both sides.

The Democratic Primary Field

Gavin Newsom, the Governor of California, currently leads the Democratic primary market as one of the party's most recognizable faces nationally. His high media profile and California donor base make him a natural frontrunner in early prediction market pricing. Alexandria Ocasio-Cortez, Pete Buttigieg, and other figures round out the competitive tier. The first-to-announce market provides an additional signal about campaign timing: traders price which candidate will formally declare a 2028 run first, often a leading indicator of behind-the-scenes fundraising and organizational readiness.

Democratic primary odds are sensitive to the party's post-2024 positioning. Debates about the party's ideological direction - progressive vs. centrist - have historically affected nomination market prices, and that dynamic will likely continue in the 2028 cycle. Watch for primary announcement dates, polling from key early states (Iowa, New Hampshire, South Carolina), and endorsements from major party figures as catalysts for significant price moves.

The Republican Primary Field

JD Vance leads the Republican nomination market, reflecting his position as Vice President and the institutional advantages that typically flow to sitting VP candidates. Marco Rubio holds second position, benefiting from his national profile and foreign policy credentials. Whether Donald Trump can run again - given the constitutional two-term limit question after serving a second term - remains an open question that prediction markets are actively pricing into the general election contract separately.

Republican primary markets tend to move sharply on news about Trump's political intentions, as his presence or absence from the field would dramatically reshape the competitive landscape. Vance's odds as sitting VP would likely decrease significantly if Trump entered or signaled interest in a third run, even though constitutional constraints would apply.

How to Read Election Prediction Market Prices

Prediction market prices are expressed in cents and map directly to implied probabilities. A candidate priced at 38¢ has a 38% implied probability of winning according to the collective market. The sum of all candidates' prices in a market typically exceeds 100¢ slightly - this "overround" represents the platform's built-in margin, analogous to the house edge in sports betting. When comparing prices across platforms on this page, look for candidates where one platform is meaningfully higher or lower than others - that spread is where trading opportunities exist.

Why Prediction Markets Beat Polls for Presidential Races

Academic research from institutions including Oxford, George Mason, and the University of Chicago has consistently found that prediction markets outperform polls as election forecasting tools. The key reason is incentive alignment: traders risk real money, so they have strong motivation to be accurate rather than to express a partisan preference. Polls, by contrast, measure stated intent without any financial accountability. Prediction markets also aggregate information from thousands of participants simultaneously, incorporating private knowledge, expert judgment, and interpretation of economic signals that standard polls cannot capture.
