Russia x Ukraine Ceasefire by 2026?

Platform comparison

Market context

Polymarket has this contract at 0% YES, which matches the market’s current read that a Russia-Ukraine ceasefire by year-end is not priced as a live base case. The event itself is simple in legal terms but hard in practice: the sides would need a mutually agreed suspension of direct military engagement, publicly announced or credibly confirmed, and it would have to stay in force for at least 10 calendar days before 31 December 2026.

That near-zero pricing sits in line with the recent pattern of short, limited pauses rather than durable battlefield stand-downs. Russia and Ukraine have already used temporary ceasefires this year around Easter and Victory Day, and those episodes show how quickly headline agreements can be narrow, unilateral or time-limited rather than the sort of general ceasefire this market requires. For conditional-token holders on Polygon, the practical takeaway is that only a confirmed, sustained, mutually recognised pause should move the odds meaningfully.

For traders, the key catalysts are formal announcements from Moscow and Kyiv, any US-mediated proposal, and credible reporting on whether both sides have accepted the same terms. Reuters reported on 14 August that Russia dismissed the idea of a Black Sea ceasefire, while also covering Ukraine’s separate offer to halt attacks on civilian targets in the Black Sea, showing that even partial de-escalation can emerge without a full ceasefire[1][2]. Watch for summit schedules, mediation channels, and whether any deal covers the whole front line rather than a maritime or humanitarian subset[1][2].

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like PolyGram trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
