Financial Times markets columnist Katie Martin and US financial commentator Robert Armstrong are scheduled to host a live "Ask an Expert" Q&A session. The event is set for Thursday, September 24, at 1 PM BST, where they will address questions regarding the biggest market risks.

Readers are encouraged to submit their questions in advance or during the live discussion. This Q&A is part of a weekly text-based expert series. The announcement for this event appeared on ft.com on September 21, 2026.

The discussion comes amidst current market concerns, including an AI-induced doomsday scenario impacting US tech stocks and OpenAI CEO Sam Altman delaying the company's IPO due to existential risks. Additionally, US borrowing costs have surged, with the 10-year yield reaching its highest level since 2007 at 5.04 percent. The hosts will likely delve into whether rising debt markets could undermine the AI boom.
