US and Iran sign an agreement by 2026?

Market context

Negotiations between Washington and Tehran have historically produced agreements only under specific political alignments and international pressure. The 2015 Joint Comprehensive Plan of Action (JCPOA) represented the most recent major accord, though the US withdrew in 2018 under the Trump administration. Current indirect talks through Omani intermediaries and European channels remain active but fragmented, with no formal bilateral negotiation framework established as of early 2024. The 85% implied probability reflects market participants' assessment that some form of written agreement—whether on nuclear constraints, sanctions relief, or prisoner exchanges—is more likely than not within the 30-month window, though the breadth of what qualifies as "any written agreement" substantially widens the resolution criteria beyond comprehensive nuclear deals.

Recent developments hinge on several observable catalysts. The outcome of the US presidential election in November 2024 will materially shift negotiating posture; a change in administration could either accelerate talks or freeze them entirely. Iranian domestic politics, particularly factional divisions between hardliners and pragmatists, constrain Tehran's negotiating bandwidth. Traders should monitor announcements from the UN, European signatories to the JCPOA, and statements from the US State Department regarding sanctions policy. Any resumption of direct talks, prisoner releases, or humanitarian agreements would signal movement toward resolution.

From a market-access perspective, UK-based traders should note that prediction markets on geopolitical agreements fall under the Gambling Commission's purview rather than FCA regulation. The German GlüStV framework treats such markets as games of chance, affecting EU accessibility. US CFTC jurisdiction over prediction markets remains limited to designated contract markets, leaving most offshore platforms outside direct oversight. Accounts without KYC verification up to £1,500 notional exposure remain available on certain platforms, though settlement and withdrawal procedures vary by jurisdiction and operator licensing.
