Concerns over soaring tech stock valuations have triggered a sell-off in equities central to the AI investment surge. SpaceX shares recently dipped below their initial listing price of $135, marking a 40 percent decline from an intraday peak of $225, shortly after the company achieved a valuation nearing $2tn.

Similarly, highly valued technology stocks have experienced a downturn, with chip stocks enduring their worst week since last year's market rout. These developments raise questions about the future of artificial intelligence and whether current market conditions represent a bubble.

To address these pressing issues, the Financial Times is hosting a live "Ask an Expert" Q&A session. Head of Lex, John Foley, and tech comment editor, Elaine Moore, will discuss the next frontiers in AI and analyze the market's current state. The text-based Q&A will be held on Thursday, July 30, from 1pm to 2pm BST. Readers are encouraged to submit their questions in advance or during the live session.
