The potential meeting between Ukrainian President Volodymyr Zelenskyy and Russian President Vladimir Putin on US soil represents a significant diplomatic development in the ongoing Ukraine-Russia conflict. Since Russia's 2022 invasion, direct high-level talks have been limited, with negotiations primarily conducted through intermediaries or international forums. A summit in the United States would signal a major shift in diplomatic relations and suggest potential peace negotiations. The market currently prices this scenario at 3% odds, reflecting widespread skepticism about such a meeting occurring before the end of 2026 given current geopolitical tensions. This low probability suggests traders view direct in-person diplomacy at that level as highly unlikely within the timeframe. The resolution is straightforward: the market settles YES only if both leaders meet in physical person on US territory before January 1, 2027. Any talks conducted virtually, in third countries, or involving lower-level officials would not satisfy the criteria. Recent statements from both sides and diplomatic channels will likely influence market odds as the year progresses.
