Odds by venue

Fair chance strips out each venue’s built-in margin (its prices add up to more than 100%), then blends the venues by how much has traded there, so the outcomes add up to 100%. Best Yes price is the cheapest ask across venues, and the payout is what a winning $100 stake returns before fees. Open a row for each venue’s contract name, bid and ask, and how closely their rules match.

Prices come from our regular polls of each venue, the oldest 1 min ago. Ages are as of when this page was built.

Mostly the same bet: 4 differences

Where they differ

  • Deadlines differ: Kalshi needs the person to take office and meet constitutional requirements before its own date (e.g. Oct 27, 2027 for Israel); Polymarket waits for a swearing-in until its date (e.g. Dec 31, 2027), then resolves to 'Other'. A government formed between the two dates splits them.
  • Kalshi counts becoming Prime Minister 'as a result of government formation' after the election; Polymarket requires a formal swearing-in (some events: a confidence vote) and excludes interim or caretaker leaders. An incumbent staying on as caretaker is No on both until a new government forms.
  • If an early election is called, Polymarket resolves on that election; Kalshi's 'next election' wording does the same, but its stated-year events (e.g. 'after the 2026 election') may not.
  • Trading closes at different times: Jul 26, 2027, 3:59 AM UTC on Polymarket and Jul 25, 2028, 2:00 PM UTC on Kalshi.

About this market

Live prediction market odds for "Next Prime Minister of Greece?". Kyriakos Mitsotakis leads at 67.9%. Next is Alexis Tsipras at 6.7%. $45K has traded across 14 outcomes on Polymarket and Kalshi. The market is expected to resolve by Jul 26, 2027.

This market will resolve to the next individual who is officially appointed and sworn in as Prime Minister of Greece following the next parliamentary election. If an election is called early, this market will immediately resolve to the individual who is officially appointed and sworn in after that election. To count for resolution, the individual must be formally sworn-in by the specified date. Any interim or caretaker Prime Minister will not count toward the resolution of this market. If no such Prime Minister takes office by December 31, 2027, 11:59 PM ET, this market will resolve to “Other”. This market will resolve based on a consensus of credible reporting. If there is ambiguity, this market will resolve solely based on official information from the Greek government.

Questions

What does the consensus price mean?

It is the price of a Yes contract that pays $1 if the outcome happens. A 14¢ price means traders put the chance near 14%. Where two venues list the same outcome, we blend their last prices, weighting the venue with more trading volume more heavily (neither counts for less than a quarter). When only one outcome can win, each venue’s prices add up to a little over 100% (its margin); the fair chance removes that margin so the outcomes add up to exactly 100%.

How is the payout worked out?

A Yes contract pays $1 if it wins, so at the best ask a $100 stake buys 100 ÷ ask contracts. At 18¢ that is about 555 contracts, paying $556 (5.56x) if Yes happens. Venue fees and price slippage on larger orders are not included.

Why do the venues show different prices?

Each venue has its own traders, fees and order book. Contracts can also settle on slightly different terms, which is why each row lists how closely the rules match.

Is a price gap an arbitrage?

Only when you can buy Yes on one venue below what someone pays for Yes on the other, after fees, and both contracts settle the same way. We show the executable bid and ask so you can check.

How fresh are these prices?

Venue prices refresh every few minutes, and the order book and live quotes stream continuously. Each venue’s card shows when we last observed it.
