Trump Says Iran Deal Is Near — Will It Be Signed by Sunday?
Manifold traders put the odds at just 25 percent — more unlikely than not — despite Trump's public optimism.
Probable’s read
Low confidence. Synthesized from prediction markets, professional analysts, public opinion, and official data.
What’s likely. CBS News reported that Trump claimed a 'settlement' had been reached with Iran and that signing could come 'as soon as this weekend,' while The Washington Post reported he canceled plans to strike Iran citing a deal that was near. However, Manifold traders put the probability of a confirmed signing time and location this week at only 25 percent, suggesting considerable skepticism that the diplomatic language translates into a formal ceremony within days. That skepticism has some grounding in recent events: DW.com reported earlier this week that the US and Iran were still trading attacks even after Trump's public statements about a deal.
What the markets say
Manifold traders priced the probability of a confirmed signing time and location for the US-Iran deal at 25 percent.

How Probable got to 25 percent
This forecast rests on a single Manifold market with under $600 in 24-hour volume, which the forecast engine weighted at roughly 40 percent of full. The realistic range runs 7 to 43 percent — a spread wide enough to encompass both 'this collapses entirely' and 'it barely gets done.' Probable reads the 25 percent as reflecting the gap between a president's public optimism and the messy reality of finalizing a major nuclear deal, but the low confidence means readers should treat this as a directional lean rather than a firm estimate.
Why it matters to you
A signed US-Iran agreement would mark a major shift in Middle East security arrangements and would end the active naval confrontation in and around the Strait of Hormuz that India, among others, has publicly protested, according to WSJ.
What to watch
Any White House or Iranian foreign ministry statement confirming a specific date, venue, and signatory list would move this probability sharply upward.
