Negotiations between the United States and Iran are anticipated to occur before Friday, according to reports from Al Jazeera citing Pakistani security sources. The assessment is based on the arrival of two U.S. C-17 Globemaster aircraft at Nur Khan Air Base near Islamabad, and the closure of roads leading to the city's Red Zone, suggesting increased security measures. Additionally, the Serena and Marriott Hotels in Islamabad have evacuated guests and halted new bookings until Friday, with the Serena Hotel previously hosting U.S.-Iran talks on April 11. On the prediction market Polymarket, the likelihood of U.S.-Iran diplomatic talks occurring before April 22 is currently at 52%, rising to 73% for talks before April 30.
