Diplomatic channels show no scheduled trilateral meeting among President Trump, President Putin, and President Zelensky before 2027, reflecting the persistent barriers created by the ongoing Russia-Ukraine conflict. Bilateral U.S.-Russia and U.S.-Ukraine contacts have continued through standard diplomatic and military channels, yet no announcements from the White House, Kremlin, or Kyiv indicate plans for a joint summit. Historical precedent favors sequential or mediated talks over simultaneous leader gatherings without prior agreements on core issues such as ceasefires or territorial terms. Trader consensus assigns a 92.5% implied probability to "No," consistent with the absence of catalysts that have previously enabled such high-level trilateral formats. A verified breakthrough in negotiations or an unexpected diplomatic initiative within the resolution window could still shift outcomes.
