At the 2026 Allen & Company Sun Valley Conference in Sun Valley, Idaho, A.I. leaders are prominent alongside returning tech titans such as OpenAI CEO Sam Altman, LinkedIn founder Reid Hoffman, and Apple’s Tim Cook. The weeklong retreat’s agenda remains undisclosed, with only photographs of attendees outside the Sun Valley Lodge permitted. Observed interactions include Sheryl Sandberg catching up with former Meta colleague Marne Levine alongside energy tech investor Phil Deutsch; Uber CEO Dara Khosrowshahi making small talk with Wendi Murdoch and investor Henry Ellenbogen; Palantir’s Alex Karp in conversation with Alexandre Arnault; and Jeff Bezos with his new wife. Snap CEO Evan Spiegel and Notion founder Ivan Zhao walked alone, while Sam Altman and his board chairman Bret Taylor faced cameras with relaxed smiles.
