About this market

Live prediction market odds for "Eritrea invades Ethiopia by...?". December 31 leads at 17%. Next is October 31 at 2.3%. $114K has traded across 2 outcomes on Polymarket. The market is expected to resolve by Nov 1, 2026.

This market will resolve to "Yes" if Eritrean military forces enter Ethiopia by the listed date, 11:59 PM ET in a military operation that establishes control over any portion of Ethiopian territory. Otherwise, this market will resolve to "No". Any Eritrean military operation which remains on the ground inside the territory of Ethiopia for less than 48 hours will not qualify. Mere presence of Eritrean military forces within Ethiopia will not alone qualify, even if for longer than 48 hours. A consensus of credible reporting must demonstrate that such presence is or was part of a military operation which established control over a portion of Ethiopia. Only the entry of Eritrean military forces into the territory of Ethiopia must occur by the listed date, 11:59 PM ET. Where Eritrean military forces enter the territory of Ethiopia by the listed date, but on the listed date, at 11:59 PM ET, control has not yet been confirmed by a consensus of credible reporting, this market will remain open for 7 additional full calendar days (ET) to allow for confirmation. If, at the end of the seventh calendar day, no consensus of credible reporting indicates that the operation has established or did establish control over part of Ethiopia, this market will resolve to "No." No single statement, denial, or presentation of evidence will govern where it is contradicted by a consensus of credible reporting. Hybrid or "grey zone" operations conducted by unmarked personnel will qualify if they are confirmed to be acting under the direct control of the Eritrean state and establish de facto control over territory. For purposes of this market, Ethiopia will be considered to be territory claimed by Ethiopia and not controlled by another state at the time of market creation. Territory claimed by Ethiopia but held by Eritrea or another state will not be relevant for purposes of this market. Search and rescue or hostage rescue operations, operations intended solely to capture specific individuals, operations solely intended to evacuate personnel or to extract or destroy equipment or infrastructure, and intelligence, reconnaissance, or surveillance operations, whether overt or covert, will not qualify unless clearly demonstrated by a consensus of credible reporting to have satisfied this market’s criteria for a “Yes” resolution. Operations conducted with the consent or at the invitation of the government of Ethiopia and strikes by air, missile, drone, or naval forces unaccompanied by ground forces will not qualify. The resolution source for this market will be a consensus of credible reporting.

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.
