2026-11-02 AI Bubble, Stock Market Risk & Retirement Planning
Could an AI stock market bubble threaten your retirement savings? On Retirement Lifestyle Advocates Radio, Dennis Tubbergen and guest Karl Denninger examine artificial intelligence investment, S&P 500 concentration, and the risks of a technology-driven market downturn. Their conversation explores AI infrastructure costs, competition from open-source technology, and Denninger’s concerns about whether revenues can justify valuations. They also discuss Federal Reserve interest rate policy, persistent inflation, and sequence of returns risk—how taking withdrawals during a market decline can undermine retirement income. Dennis rounds out the episode with commentary on federal deficits, mortgage rates, and falling home sales. Mr. Karl Denninger is an American technology businessman, finance blogger, author, and political activist, sometimes referred to as a founding member of the Tea Party movement. Mr. Denninger is the author of the book Leverage: How Cheap Money Will Destroy the World. In the book, Denninger presents an inside look at how moneyed and powerful interests debase the dollar through the willful and intentional failure to honestly represent short and long-term mathematical truths that underlie all economic systems.
