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 8 min ago. Ages are as of when this page was built.

About this market

Live prediction market odds for "LA28 Olympics run as scheduled?". Yes leads at 85.5%. $56K has traded across 1 outcome on Polymarket. The market is expected to resolve by Jul 26, 2028.

This market will resolve to “Yes” if at least 177 gold medals have been officially awarded at the 2028 Los Angeles Olympic Games (LA28) by July 25, 2028, 11:59 PM PT. Otherwise, this market will resolve to “No”. For the purposes of this market, “officially awarded” is defined as the gold-deciding final for the relevant event concluding and the gold medalist(s) being determined under official results. A qualifying awarding will still count towards the total regardless of whether the results are later reviewed or modified. Medal ceremonies aren’t required for an awarding to qualify. Each event will count once towards the total; a team gold or a shared gold will still count as one event. Both the specified threshold and deadline will remain fixed regardless of whether events are added to or cut from the program, or if LA28 is postponed, suspended, shortened, relocated, or rescheduled in any way. Heats, prelims, semifinals, and any phase that doesn’t decide gold will not count. Events postponed past the deadline or cancelled without deciding a gold medalist will not count. If LA28 officially awards at least one gold medal but is cancelled or curtailed, this market will resolve on the number of officially awarded gold medals up until that point. The primary resolution source for this market will be a consensus of credible reporting; however, if there exists any ambiguity, this market will resolve solely based on official information from the organizers of LA28, including the Los Angeles Organizing Committee (https://la28.org/) and the International Olympic Committee (https://www.olympics.com/).

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.
