The much-anticipated Web Summit in Portugal is kicking off this week amid heightened scrutiny of the AI-fueled market rally that has captivated — and now unsettled — investors worldwide. Growing concerns over a potential AI bubble have sent global markets into a tailspin, following news that famed short-seller Michael Burry placed a $1.1 billion bet against AI giants Nvidia and Palantir.

Despite the market jitters, AI remains the star attraction at the Web Summit. The conference agenda leaves little doubt about the industry’s dominance, with sessions such as “Smarter Plays: How AI is Changing the Game,” “The Age of AI,” “The Future of AI is Visual,” and “AI Talent Wars.” Notably, there’s little mention of the mounting fears over inflated valuations or speculative excesses that have rattled investors in recent weeks.

While the sharp correction in AI stocks — stretching from Silicon Valley to London to Tokyo — looms large over the event, organizers and attendees are facing another unexpected issue: a private jet traffic jam. Reports indicate that Lisbon Airport has been overwhelmed by incoming flights, forcing some private jets to divert to airports over two hours away from the city.

Web Summit organizers issued a notice to attendees, warning, “Please be advised there is currently a shortage of private jet slots during Web Summit at Lisbon airport and surrounding smaller airports.”

As the world’s biggest tech minds gather to discuss the future of artificial intelligence, the juxtaposition is striking — a booming industry grappling with both sky-high expectations and ground-level logistical chaos.
