What Prediction Markets Are Forecasting
Prediction markets currently give about a 1 in 4 chance that the United States will agree to a formal security guarantee for Ukraine by June 30, 2026. This means traders collectively see such a deal as unlikely, though not impossible, within the next year and a half. A "security guarantee" in this case means a binding U.S. commitment, like a treaty or formal pact, to defend Ukraine if it is attacked again.
Why the Market Sees It This Way
The low probability reflects several political realities. First, the outcome of the 2024 U.S. presidential election is a major factor. Former President Donald Trump, who is favored to win, has been skeptical of long-term aid commitments to Ukraine and has emphasized ending the war quickly, potentially through a negotiated settlement. A formal security guarantee would be a long-term, binding obligation that seems at odds with this stance.
Second, the U.S. has historically been very cautious about extending formal security guarantees, which are typically reserved for NATO allies. Creating a new, bilateral defense treaty with a country actively at war would be a significant and unusual step. Even strong supporters of Ukraine in Congress have focused on aid packages, not treaty-level commitments.
Finally, the terms of any potential deal are unclear. A guarantee would require agreement on what the U.S. is promising to do, and under what conditions. Negotiating these details with a war ongoing is a complex hurdle that makes a quick agreement difficult.
Key Dates and Events to Watch
The single biggest event is the U.S. presidential inauguration on January 20, 2025. The policy direction of the new administration will become clear in the months that follow. Watch for early statements from the White House and Secretary of State on Ukraine policy.
Other signals include any major shifts on the battlefield that change Ukraine's negotiating position, and the progress of Ukraine's talks to join the European Union. If EU accession advances, it might influence U.S. calculations. The June 2026 deadline itself is not tied to a specific event, so the probability may shift gradually as the date approaches without a deal.
How Reliable Are These Predictions?
Markets are generally decent at aggregating political odds, especially when an event depends on a clear binary choice and known actors, like a U.S. administration. However, they can be volatile around major news events or unexpected diplomatic breakthroughs. Their main limitation here is the long time horizon. A lot can change in international politics over 300 days, so today's odds are a snapshot of current sentiment, not a fixed forecast.
