A Russia-Ukraine ceasefire is one of the most actively traded geopolitical contracts in prediction-market history. As of late April 2026, more than $14.5 million has cleared on the headline ceasefire markets alone. The aggregate signal is unambiguous: traders do not believe a near-term deal is coming.
The exact price stack is what makes this market useful. Each contract resolves on a specific calendar deadline, and the prices form a curve that reveals how traders are weighting time, diplomacy, and battlefield momentum.
The current price curve
| Candidate | Implied | Prob. | Δ pp |
|---|---|---|---|
| Ceasefire by April 30, 2026 | | 1% | — |
| Ceasefire by May 31, 2026 | | 3% | — |
| Ceasefire by June 30, 2026 | | 8% | — |
| Ceasefire by end of 2026 | | 26% | — |
A 0.5% price for the April deadline is, in market terms, a near-certainty against. A 26% year-end price is meaningfully higher — but still implies traders think no ceasefire by year-end is roughly three times more likely than ceasefire by year-end.
Why the markets are this bearish
Three structural factors anchor the price.
Divergent terms. Ukraine’s stated baseline — voiced repeatedly by Volodymyr Zelenskyy — includes full withdrawal of Russian forces and post-war security guarantees from European allies and the United States, typically interpreted as NATO-adjacent. Vladimir Putin’s baseline, restated in Spring 2026, includes territorial recognition of the four annexed oblasts plus Crimea, a return of certain prisoners of war on Russian terms, and a Ukrainian commitment against future NATO membership. These are not adjacent positions. They are not even in the same negotiating frame, and no peace deal sits inside the overlap.
No durable mediator. Donald Trump’s administration has framed itself as the central US mediator, but Trump-backed talks have stalled since late Q1 2026. Turkey has pushed for a Zelenskyy-Putin summit; nothing has been scheduled. European allies have floated parallel tracks with mixed signals from Washington. The short-lived 32-hour Orthodox Easter cease fire on April 11–12 ended with both sides claiming violations and no follow-on framework.
Continued battlefield activity. Ukrainian forces’ long-range drone strikes on Russian refineries, Russian attacks along the eastern axis, and persistent missile exchanges all signal escalation rather than de-escalation. Energy-market spillovers have also tightened the link between this conflict and Middle East dynamics, where Iran-related volatility continues to ripple into European fuel pricing. Markets price war continuation, not negotiation theater.
How to read a calendar curve
The shape of the price curve is itself a forecast. From 0.5% (April) to 3% (May) to 8% (June) to 26% (year-end), the curve climbs roughly six-fold from one month out to eight months out. That is consistent with traders pricing:
- Near-term: a near-zero base rate of ceasefire announcements in any given month, given the current diplomatic state.
- Medium-term: a non-trivial probability that a single catalyst — a leadership change, a battlefield collapse, a sanctions breakthrough — could swing the situation by year-end.
- Long-term: uncertainty compounds, but most of that compounded probability mass arrives in H2 2026, not H1.
If you are using these markets as a planning input — for energy, for shipping, for defense allocation — the curve is more informative than any single number.
What would move the price
Five catalysts that have historically moved ceasefire-market pricing by at least 5 percentage points:
- A direct Putin-Zelenskyy meeting. Even a venue announcement has historically moved year-end odds 6–8 points.
- A US sanctions bill change. Either tightening or loosening signals a policy posture and reprices the market.
- A major battlefield event. A capital-city strike, a corps-level encirclement, or the loss of a regional hub has been worth 4–10 points historically.
- Domestic political shifts. Russian succession signals or a Ukrainian government reshuffle.
- Energy infrastructure damage. Sustained refinery losses or grid attacks shape both economic pressure and bargaining position.
For traders comparing this to other geopolitical tail-risk markets, the China-Taiwan invasion odds page tracks a similar binary contract with a longer resolution horizon.
What the price is not saying
Three common misreadings worth flagging:
- A 26% year-end price is not a 26% chance of “peace.” It is a 26% chance of a binding ceasefire agreement by the resolution criterion. A frozen conflict, a soft truce, or a partial-withdrawal scenario could leave the market resolving “No” while the public conversation calls it peace.
- The price is not a poll. It is a clearing equilibrium. A handful of large traders can move thin overnight markets several points. Volume-weighted prices are more useful than headline ticks.
- Volatility ≠ news. Some of the largest single-day moves in this market have come on quiet news days because of liquidity events, not signal.

What to watch in May and June
The May 31 deadline contract is the cleanest near-term signal. If it climbs above 6%, traders are pricing a meaningful diplomatic shift. If it drifts below 2%, the market has effectively written off Q2 as a ceasefire window.
Beyond Q2, the year-end contract becomes the dominant gauge. A break above 35% would be the first time in the market’s history that traders gave more weight to settlement than continuation. We are not close to that level.
Common questions
What are the current Russia-Ukraine ceasefire odds?
On Polymarket: 0.5% for a ceasefire by April 30, 2026; 3% by May 31; 8% by June 30; and 26% by the end of 2026. These prices update continuously and reflect actual capital at risk.
Why are the year-end odds so much higher than the near-term odds?
Time gives more room for a single low-probability catalyst — a leadership change, a battlefield collapse, a sanctions breakthrough — to occur. Traders are not pricing a deal as likely; they are pricing the cumulative chance that something changes the diplomatic frame.
How is "ceasefire" defined for resolution?
Polymarket contracts require a publicly announced bilateral agreement covering active combat operations, sourced to credible reporting. Humanitarian pauses, unilateral truces, or regional ceasefires generally do not qualify. Always read the specific resolution rule.
How much money is on these markets?
More than $14.5 million had traded across the headline ceasefire contracts as of late April 2026. That makes them among the deepest geopolitical markets on the platform, though still smaller than US presidential markets.
Can US residents trade these markets?
Polymarket geofences US users, so US residents should not access it. Kalshi does not currently list a comparable bilateral-ceasefire contract. See our Kalshi vs. Polymarket comparison for the full jurisdictional picture.
