2028 presidential election odds

The 2028 board is already one of the highest-volume politics markets in the world — and it's unusually Florida-flavored. Here's how the contracts work, what actually moves them, and how to read the price instead of the noise.

Where to trade 2028 odds

Two venues matter for a Florida trader. Polymarket runs the deepest 2028 books — the Republican and Democratic nominee markets plus the general-election winner — with dozens of names quoted, which is where long-shot pricing actually exists. Kalshi is the CFTC-regulated U.S. exchange: fewer names, USD funding straight from a bank account, and U.S. tax paperwork handled for you.

If you want granularity, Polymarket. If you want a regulated venue and clean records, Kalshi. Plenty of people keep accounts on both and trade whichever quotes the better price on the name they care about.

The three contract types

A useful sanity check: a candidate's general-election price should never exceed their nominee price. When it briefly does — usually after a viral headline — that's an arbitrage, and it closes fast.

The Florida angle

Florida is over-represented on the 2028 Republican board for a structural reason: Ron DeSantis's second term as governor ends in January 2027, which removes the "he's busy running a state" discount that hangs over sitting governors. Traders also read the state's own 2026 races — the governor's race and the Senate contest — as a live read on whether the Florida coalition that produced 2022's margin still holds.

That's why a Florida primary result like August 18, 2026 could move a national 2028 contract by several cents in a day. If you follow Florida politics closely, this board is where that knowledge is worth the most.

What actually moves the board

• November 2026 midterms: the single biggest scheduled repricing. Expect wide swings the week after.
• Formal announcements: a declared campaign usually pulls 5–15¢ from the rest of the field within hours.
• Withdrawals and health news: the fastest moves on the board, and the ones most likely to be over-extrapolated.
• Early-state polling: matters far more from mid-2027 onward than it does today.
• Endorsements from party leadership: strong signal on nominee markets, weak signal on the general.

Read the resolution rules first

Nominee markets pay on the formal nomination — delegate math and primary wins are only evidence, not settlement. The edge cases worth knowing before you size: a contested convention, a candidate withdrawing after clinching, or a third-party run that keeps a name on the general board while removing them from a nominee book. Each venue handles these differently, and the rules tab is the only authority.

How to trade it two years out

Two years is a long hold. The realistic approach is not "pick the winner" but "buy a name the market hasn't priced for a catalyst you can see coming," then sell into the spike rather than waiting for a 2028 convention. Long-shots at 3–6¢ carry asymmetric payoffs precisely because the field isn't set — and a 4¢ contract only needs to reach 8¢ to double.

Size accordingly. Political markets are slow, headline-driven, and capable of sitting flat for months before moving 20¢ in a week. Never put money on the board that you need before November 2028.

Frequently asked questions

Where can Florida residents trade 2028 election odds?

Polymarket lists the deepest 2028 books — nominee markets plus the general-election winner — and Kalshi runs CFTC-regulated U.S. political event contracts. Both are open to eligible Florida users; Kalshi settles in USD, as does Polymarket US.

Which 2028 markets have the most volume?

As of early August 2026, the Republican Presidential Nominee 2028 and Presidential Election Winner 2028 books are among Polymarket's top politics markets, with the Democratic nominee book close behind. Volume rises sharply after each midterm result.

Why do Florida names dominate the Republican board?

Ron DeSantis's term as governor ends in January 2027, which frees him for a national run, and Florida's 2026 Senate and governor races are treated as a proxy for the state's coalition. Traders price Florida results straight into the 2028 board.

How do nominee markets resolve?

They typically resolve to the candidate formally nominated at the party's 2028 convention, not to primary polling or delegate estimates. Withdrawal, death, or a contested convention is handled by the rules tab — read it before sizing.

Are 2028 odds a better signal than polls this far out?

They are a different signal. Markets price probability including who actually runs, which polls can't. Two years out, both are noisy — treat any 2028 price as a live opinion that will reprice hard after the November 2026 midterms.

What's the cheapest way to express a long-shot 2028 view?

Nominee markets. A candidate at 4¢ pays 25-to-1 if they take the nomination, and the position can be sold into any news-driven spike long before the convention — you don't have to hold to resolution.
