Artificial intelligence will be a key focus of the talks between members of the business and political elite in Lisbon, Portugal.

The annual Bilderberg event is shrouded in mystery, with discussions held behind closed doors and under Chatham House rules.

OpenAI CEO Sam Altman will join forces with key leadership from companies like Microsoft and Google this week as a secretive meeting of the business and political elite kick-starts in Lisbon, Portugal.

Artificial intelligence will top the agenda as the ChatGPT chief meets with Microsoft CEO Satya Nadella, DeepMind head Demis Hassabis and former Google CEO Eric Schmidt at the annual Bilderberg Meeting.

The tech titans will be joined by political heavyweights including former U.S. Secretary of State Henry Kissinger, NATO Secretary-General Jens Stoltenberg and Ukrainian Foreign Minister Dmytro Kuleba for a range of discussions spanning international relations, trade, energy and finance.
