Trump confirmed calls with both Putin and Zelensky, pointing to potential U.S.-mediated de-escalation efforts. The odds of a Russia-Ukraine ceasefire by May 31, 2026, sit at 4% YES, unchanged from yesterday.
Market reaction
The May 31 ceasefire market remains flat despite the calls. Traders appear to be waiting for concrete developments beyond phone conversations, such as a trilateral summit or a formal ceasefire announcement. The long-term ceasefire outlook for 2027 could see movement if mediation efforts produce something tangible, but the immediate reaction is muted.
Why it matters
The market is thin. It would take just $2,249 to move the price 5 percentage points, and daily trading volume is $5,779. That means a single large buy could shift the odds significantly. The calls are a positive signal, but without a firm commitment or an official summit, the price reflects how far apart the parties still are.
What to watch
Track further statements from Trump, Putin, or Zelensky, particularly any announcement of a mediated negotiation. Iraqi leaders are also set to meet Putin in Moscow, which could affect broader diplomatic dynamics around the conflict.
For speculative traders, buying YES at 4¢ is a high-risk, high-reward position with a 25x return if a ceasefire is announced by May 31.
