ONE BIG THING

Anti-AI groups in the spotlight after the attack on Sam Altman

The firebombing and attempted murder of OpenAI CEO Sam Altman has drawn attention to two anti-AI groups linked to the alleged arsonist: Pause AI and Stop AI. Both have condemned the violence and said the suspect is not a member of their organizations. But who are these groups, and what do they want? Fortune’s Sharon Goldman talked to Pause AI US leader Holly Elmore, the Berkeley-based activist with a PhD from Harvard. The group has “no reason to think that this person had much to do with us,” she said, he “didn’t get any further in onboarding or having any official role.”

IRAN

Peace is in danger of breaking out—but the Strait of Hormuz remains blocked

The U.S. and Iran are considering a two-week extension to the ceasefire, Bloomberg reported. Separately, President Trump said the leaders of Israel and Lebanon will engage in talks for the first time in 34 years. Lebanon, however, denied talks were happening this morning. Context: Iran once denied peace talks were on the cards, too—right before its officials showed up in Islamabad to discuss an end to the war.

Meanwhile, the Strait of Hormuz remains almost totally blocked. The U.S. military says zero ships have passed their blockade, which began on Monday, and 10 ships have been forced back through the Strait and into the Gulf.

- Cat and mouse: Two sanctioned ships linked to Iran did manage to sneak through the Strait by hugging the coast of Iran, per Bloomberg.

- The Rich Starry, the Chinese ship Fortune is tracking that made a failed escape attempt on April 14, appears to be sitting just off Iran’s Qeshm Island, near the entrance of the Strait today, according to MarineTraffic.com (map below).

- Trump said: “China is very happy that I am permanently opening the Strait of Hormuz. I am doing it for them, also - And the World. This situation will never happen again.” Read his statement here.

Why gas prices don’t fall even if you have energy independence

The U.S. remains bountifully supplied with almost record-high crude oil and natural gas production. President Donald Trump has touted the nation’s “energy independence.” So why is the average price for a gallon of gasoline $4.11?

“The problem is that oil is a global commodity. We may have plenty of oil—there’s no shortage of U.S. oil—but energy independence is somewhat of a fallacy,” said Jim Wicklund, veteran oil analyst and managing director at the PPHB energy investment firm, in an interview with Fortune’s Jordan Blum. “We still have to pay the going world price. It’s a global price.”

DIMON DIVERSIFIES

Jamie Dimon sells $40 million in shares of J.P. Morgan

J.P. Morgan boss Jamie Dimon sold the stock as part of a pre-arranged 10b5-1 trading plan and he still holds 76.3 million shares valued at $23.4 billion, SEC disclosures show. It’s his second sale of 2026 so far, Fortune’s Amanda Gerut tells me. In February, Dimon sold 69,512 shares for $21.4 million. The company previously announced he would be diversifying his holdings in JPM.
