Executive summary Geopolitics: Trump said that a deal with Iran to reopen the Strait of Hormuz is near. Rubio called Cuba a leading state sponsor of terror and questioned whether diplomacy with the regime would work. * Will the US carry out a strike on Cuba's territory by the end of July 2026?

″🟡 US-Iran stalemate continues, Putin says Ukraine war may come to an end, White House considers AI executive order || Global Risks Weekly Roundup #19/2026″ by Nuño Sempere, Vidur Kapur, belikewater, Tolga Bilge

Executive summary Geopolitics: Donald Trump called Iran's response to the US’ latest peace proposal “totally unacceptable”. Vladimir Putin hinted that the Russia-Ukraine war may be nearing an end. * Will Russia and Ukraine end the war with a signed agreement by the end of 2026?

Our forecasters believe there's a 32% (27% to 40%) probability. Economy: The S&P 500's rebound since late March has been driven by the smallest number of stocks on record, namely a handful of Big Tech stocks. * Will the tech companies Alphabet, Nvidia, Amazon, Broadcom, and Apple account for at least 65% of overall growth of the S&P 500 in Q4 of 2026?

″🟡 Iran says it will target US naval vessels, GPT-5.5 similar to Mythos on cyber tasks || Global Risks Weekly Roundup #18/2026″ by Nuño Sempere

Executive summary Geopolitics: Iran unveiled a fresh peace proposal, but Trump was not satisfied with it and says that Iran has not paid a big enough price for the war to end yet. The US said it would guide stranded vessels through the Strait of Hormuz, but Iran warned it could attack US naval vessels in response. * Will Congress put any constraints on the war in Iran by June 1, 2026, using the War Powers Act? Our forecasters think there's a 6% (5% to 7%) chance. * Will there be a new conflict in Africa that kills over 100 thousand people before May 1, 2027?

Technology and AI: OpenAI's GPT-5.5 was found to have a similar level of performance to Anthropic's Mythos model on the UK AISI's suite of cyber tasks. Unlike Mythos, it has been publicly deployed. * Will OpenAI de-deploy GPT-5.5, making it unavailable to the general public, before 2027 because of its use in cyberattacks?
