"What will be in a US-Iran deal in 2026?" Live Odds and Polymarket Predictions

Diplomatic speculation around a possible US-Iran deal has been running for months, and Polymarket keeps a running market on exactly which terms might actually make it into any final agreement. The market prices out each possible provision independently — will it be in the deal or not — and right now, traders are skeptical across the board, including on Iran reconstruction funding.

For those unfamiliar, Polymarket is a leading prediction market platform where users trade on the probability of real-world events. Unlike a diplomatic leak or an anonymously sourced report, Polymarket odds reflect the collective wisdom of traders putting real money behind their predictions — making it one of the more responsive real-time gauges of how seriously the market is taking any specific term rumored to be under negotiation.

Live Polymarket Odds: Will Iran Reconstruction Funding Be in a 2026 US-Iran Deal?

The embed below shows live, real-time Polymarket odds for the Iran Reconstruction Funding contract within this market. Unlike a standard preview article, the odds you see here are always current — no need to search elsewhere for the latest numbers.

Reconstruction funding is currently the most-favored term on the board, and even it trades at just 12¢ on Polymarket, with “No” at 90¢. That 11% probability is down 59% from where the contract started, one of the steepest declines of any term in this market — a sign that whatever early optimism existed around a reconstruction-fund provision has largely faded as negotiations have dragged on.

Every term on the board has traded down recently — reconstruction funding is off 59%, the enrichment moratorium is down 12%, the uranium enrichment cap is down 45%, and dilution of Iran's uranium stockpile has fallen 61%. Across the board, “No” sits between 90¢ and 94¢ on every listed term, suggesting traders currently think a comprehensive deal covering any of these specific provisions is unlikely to materialize before the market's close. This market has traded roughly $799,000 in total volume and is scheduled to close on December 31, 2026.

How Polymarket Works for "What's in the Deal" Markets

Polymarket operates as a prediction market where contracts are priced between $0 and $1, representing the implied probability of an outcome occurring. A “Yes” contract on Iran Reconstruction Funding priced at $0.12, for example, implies roughly an 11% probability that a written US-Iran agreement will include that specific provision — based purely on what traders are collectively willing to pay.

Unlike a single-outcome market, this one lets every possible deal term carry its own independent Yes/No contract, since a real diplomatic agreement could plausibly include several of these provisions at once, or none of them. That structure makes it useful for tracking not just whether a deal happens, but what shape it's likely to take if it does.

Per the visible portion of the market's resolution rules, this market resolves to “Yes” for a given term if a written diplomatic instrument between the United States and Iran establishes a non-Iranian fund or the relevant provision described by that contract; otherwise it resolves to “No.” Each term's contract resolves independently of the others.

What Drives Polymarket Odds on US-Iran Deal Terms?

Polymarket odds on a market like this one are influenced by a range of factors that traders continuously incorporate into their positions:

• Negotiation progress: Reports on the state of direct or mediated talks are typically the fastest-moving input to any individual term's price.
• Official statements: Public remarks from US or Iranian officials confirming or ruling out a specific provision can move that term's contract quickly.
• Third-party mediator reports: Updates from intermediaries such as Gulf states or other diplomatic channels often shape how traders read the likelihood of specific terms.
• IAEA and inspection reports: Findings on Iran's enrichment levels and stockpiles feed directly into the enrichment-related contracts on this board.
• Broader deal momentum: When traders grow more or less confident that any deal happens at all, it tends to move every individual term's price in the same direction, as seen in this market's recent across-the-board declines.
