Key Takeaways
- Polymarket’s top pick is Abbas Araghchi at 22% implied odds, ahead of Steve Witkoff at 18.5% and JD Vance at 16.5%.
- Traders marked down Donald Trump’s attendance to 5% as attention stayed on G7 diplomacy and the planned US-Iran deal signing.

G7 leaders were set to spend the final day of a summit in Evian focused on the security risks posed by artificial intelligence and social media, after earlier sessions centered on Iran and Ukraine. French President Emmanuel Macron said the group would discuss improving cyber security and protecting children and democracies, as leaders sought consensus statements on the Middle East and Ukraine ahead of separate press conferences around 1300 GMT. The meeting has been dominated by U.S. President Donald Trump, with allies seeking clarity on his deal aimed at ending the war with Iran, which the report said is due to be signed in Switzerland on Friday. Macron also invited Trump to dinner at the Palace of Versailles after the summit, and Trump said he accepted the invitation while describing the venue as “the real deal.” The report also said AI industry executives including Sam Altman, Dario Amodei and Arthur Mensch were expected to attend a lunch with the leaders.
Polymarket Data: $361,711 Volume as Abbas Araghchi Leads at 22% With No Outcome Above the Low-20s
On Polymarket, the “Who will attend US-Iran signing ceremony?” market had $361,711 in volume, with the field tightly clustered and no single outcome priced above the low-20s. Abbas Araghchi led at 22% Yes / 78% No, followed by Steve Witkoff at 18.5% Yes / 81.5% No and JD Vance at 16.5% Yes / 83.5% No. Donald Trump was priced at 5% Yes / 95% No, after a sharp repricing versus the prior 50.5% level shown in the historical snapshot.
