The Iranian nuclear and sanctions landscape has shifted significantly in recent months, reopening questions about potential negotiations and policy reversals. These three prediction markets explore the probability of three specific U.S.-Iran agreements by May 31, 2026: a Trump administration decision to remove transit fees currently imposed on Iranian vessels in the Strait of Hormuz, permission for Iran to continue uranium enrichment at higher levels, and the unfreezing of Iranian assets held in international accounts. Each outcome represents a distinct dimension of U.S.-Iran relations—shipping access, nuclear capability, and financial sovereignty—yet all three are ultimately driven by the same core question: whether the current administration is willing to shift course and re-engage with Iran on major policy issues. Prediction markets like these aggregate real-time forecasts from traders, researchers, and analysts monitoring political signals, public statements, and diplomatic developments. The prices you'll see reflect a collective probability assessment from all participants who believe each outcome is more or less likely given the available information. Whether you're assessing geopolitical risk, studying how markets process political uncertainty, or following Iran policy closely, these three markets offer a focused view into a key international relations question. The clustering here reflects how policy experts and traders tend to group them—as interdependent components of a broader negotiation rather than isolated decisions. As we move toward the May deadline, watch for signals including official government statements from both countries, any diplomatic visits or talks, international media coverage of negotiations, and developments in the broader Middle East that might shift probabilities.
