Prediction markets put the probability at 16%: Russia x Ukraine ceasefire by December 31, 2026. Currently, markets see this as unlikely (16% YES). Many observers view the military situation as tilted in Russia's favor, and concerns are mounting over support fatigue in Europe.
On July 13, 2026, the Coalition of the Willing convened in Paris and issued a joint statement reaffirming support for Ukraine, calling for an “immediate and complete ceasefire” and direct peace negotiations between Russia and Ukraine with U.S. participation. This diplomatic push follows a pattern of stalled efforts throughout the year: in February 2026, Ukraine’s allies urged Russia to agree to a “full, unconditional ceasefire,” while in April 2026, Kremlin spokesman Dmitry Peskov rejected President Volodymyr Zelenskyy’s proposal for an Orthodox Easter truce, stating that Ukrainian forces should have withdrawn from Donetsk oblast “yesterday.” The repeated rejection of short-term and long-term truce proposals underscores the wide gap between the two sides’ positions on any potential russia x ukraine ceasefire [France24, Feb 25] [Russia Matters, Apr 01].
The military situation remains tilted in Russia’s favor, according to analysts at the Japan Institute of International Affairs, with mounting concerns over European support fatigue as the war grinds into its fourth year. Ukraine faces a difficult choice over which conditions it deems non-negotiable and what it is willing to sacrifice in return, with negotiations highly likely to continue through 2026. Even a theoretical agreement involving the transfer of occupied eastern regions would not guarantee stability, as Russia could cite the need to address “root causes” to prolong hostilities. Meanwhile, the Kremlin has demonstrated a preference for limited, tactical pauses—such as a week-long moratorium on energy infrastructure strikes agreed with U.S. President Donald Trump in January 2026—rather than a comprehensive, verifiable russia x ukraine ceasefire [JIIA, May 28] [Critical Threats, Mar 09].
A structural factor likely to determine the outcome is the deepening Russia-North Korea relationship, which provides Moscow with artillery and missile supplies while complicating Western diplomatic leverage. On the other side, the Coalition of the Willing has reiterated that binding security guarantees for Ukraine must be part of any larger peace plan, a condition Russia has consistently rejected. The 14% probability assigned to a russia x ukraine ceasefire by December 31, 2026 reflects the persistent reality that neither side appears willing to accept the other’s core demands: Ukraine insists on territorial integrity and security guarantees, while Russia demands Ukrainian withdrawal from Donetsk and refuses to commit to long-term cessation of hostilities. With European aid packages pledged through 2026 and no breakthrough in direct talks, the window for a negotiated settlement before year-end remains narrow [ISW, Jul 15] [France24, Feb 25].

8 of 8 models estimate NO fair value above market (70–95c vs 86c). Gemini Flash leads with 85% confidence.
Models estimate fair value of NO at 87c — market prices it at 86c. 1-point gap supports NO.
Smart money is uniformly positioned on NO, having entered at high prices (71c-78c), signaling conviction that a ceasefire is unlikely by end-2026. Their entries near the top of the range suggest they expect continued downside for YES, and their lack of YES exposure implies no hedging for a positive outcome. This one-sided positioning could exacerbate YES sell-offs if momentum turns negative, but also leaves NO vulnerable to a sharp reversal if unexpected peace talks surface.

All tracked NO positions are profitable, with entries between 71c and 78c, while no YES positions are in profit. This indicates strong downward pressure on YES, as NO holders have a significant cushion and may resist price rallies toward their cost basis. The 14c YES price suggests the market heavily discounts a ceasefire, with NO support likely to persist unless new catalysts emerge.
