About this market

Live prediction market odds for "Who will be the next US Ambassador to Greece?". Gus Bilirakis leads at 11.9%. Next is Nicole Malliotakis at 9.1%. $19K has traded across 10 outcomes on Polymarket and Kalshi. The market is expected to resolve by Jan 19, 2029.

This market will resolve according to the next individual to formally assume the position of United States Ambassador to Greece between market creation and January 19, 2029, 11:59 PM ET. A person will be considered to formally assume the position of United States Ambassador to Greece if they are appointed to the position by the President and confirmed by the Senate, or if they assume the position through a recess appointment. Acting or interim holders of the specified position do not qualify. If no individual assumes the position by January 19, 2029 at 11:59PM ET, this market will resolve to "Other". The resolution source for this market will be official information from the White House or United States Senate; however, a consensus of credible reporting may also be used.

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.
