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

Mostly the same bet: 4 differences

Where they differ

  • Buckets assume 25 bp steps: Kalshi 'Cut >25bps' / 'Hike >25bps' and Polymarket '50+ bps' differ for a move strictly between 25 and 50 bps; Kalshi 'Cut 1-25bps' also covers moves under 25 bps.
  • Polymarket names the reference rate per bank (Fed: upper bound of the target range; ECB: deposit facility rate; BoJ: uncollateralized overnight call rate); Kalshi settles on the announced action.
  • Both settle on the scheduled meeting in the named month; an unscheduled move between meetings counts for neither.
  • Trading closes at different times: Dec 15, 2026, 12:00 AM UTC on Polymarket and Dec 15, 2026, 9:59 PM UTC on Kalshi.

About this market

Live prediction market odds for "Central Bank of Chile decision in December". No change leads at 48%. Next is 25 bps increase at 42.7%. $36K has traded across 5 outcomes on Polymarket and Kalshi. The market is expected to resolve by Dec 15, 2026.

This market will resolve according to the change in basis points in the monetary policy rate resulting from the December 2026 meeting of the Central Bank of Chile (Banco Central de Chile), relative to the level it was prior to this meeting. The resolution source will be official information from the Central Bank of Chile, including the statement or release from its December 2026 meeting, scheduled for December 15, 2026, as listed on the official Central Bank of Chile calendar (https://www.bcentral.cl/es/web/banco-central/noticias-y-publicaciones/prensa/calendario-de-politica-monetaria-y-financiera). This market may resolve as soon as the statement or release of the Central Bank of Chile resulting from its December 2026 meeting with relevant data is issued. If the specified rate is defined by an upper and lower bound, the relevant change will be the change to the upper bound. If the specified rate is changed to a level not expressed in the displayed options, the change will be rounded according to the following guidelines. Increases or decreases of less than 25 bps will be rounded to 25 bps (e.g. an increase or decrease of 10 bps would be considered to be an increase or decrease of 25 bps). Increases or decreases of greater than 25 bps will be rounded to the nearest 25 bps and will be rounded away from 0 in cases of equidistance (e.g., an increase or decrease of 37.5 bps would be considered to be an increase or decrease of 50 bps). Displayed options of “Increase” or “Decrease” will include policy rate increases or decreases of any size. If the specified meeting is postponed to a date and time before the start of the next scheduled meeting, this market will resolve based on the outcome of that postponed meeting. If the specified meeting is cancelled, or postponed such that no decision is announced by the start of the next scheduled meeting, this market will resolve to the “No Change” bracket. Emergency changes to the specified rate not resulting from the specified meeting will not be considered.

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.
