# Gensler Warns AI Boom Faces Pullback in 18 Months _Gary Gensler told Bloomberg Podcasts the AI boom will pull back in 18-30 months, with debt and off balance sheet guarantees setting the depth._ **Published:** 2026-10-27 **Source:** https://www.startuphub.ai/ai-news/artificial-intelligence/2026/gensler-warns-ai-boom-faces-pullback-in-18-months --- Former SEC Chair Gary Gensler told [Bloomberg Podcasts](https://www.youtube.com/watch?v=rjcbkE9zDSc) the AI boom will decelerate and then reverse in the next 18 to 30 months, and the depth will depend on how much debt is in the system and who holds it. The host asked Gensler to frame a day that saw Anthropic file its S-1 and what he called a $90 billion equity offering from Meta, and Gensler said history shows capital markets overfund in exuberance. Everyone wants in on railroads, canals, the internet and now AI, he argued, so the question is when the pullback comes and how far it goes. Gensler pointed to [Broadcom](https://www.startuphub.ai/ai-news/public-companies/2026/broadcom-s-ai-outlook-miss-hits-stock) and its late disclosed $63 billion package of complex guarantees that was not in the initial S-1 and must be amended in, alongside similar structures at AMD. He said those off balance sheet guarantees and special purpose vehicles feel like the 2008 era and warned that more than $500 billion in new AI-related debt raised this year is pushing toward $600 billion with the [Broadcom](https://www.startuphub.ai/ai-news/public-companies/2026/broadcom-stock-drops-on-disappointing-ai-chip-outlook) deal. ![The AI Boom Will Pull Back, Warns Former SEC Chair Gary Gensler - Bloomberg Podcast](https://img.youtube.com/vi/rjcbkE9zDSc/maxresdefault.jpg) The AI Boom Will Pull Back, Warns Former SEC Chair Gary Gensler, Bloomberg Podcast On regulation, Gensler said the U.S. does best staying merit neutral if disclosures are complete, but a cleanup crowd will have to arrive afterward. He said if he were at the [Federal Reserve](https://www.startuphub.ai/ai-news/prediction-markets/2026/prediction-markets-eye-fed-rate-decisions) this week he would weigh what a capex boom slowdown means for inflation and growth in 2027 and 2028, predicting a rate increase in December and then a pause. He left the Washington part unanswered. At MIT, where he now teaches with Nobel laureate Simon Johnson, Gensler said 98% of students use AI regularly and faculty do too. He urged them to keep training their brains rather than offloading thinking, and said the safety debate that [Hinton](https://www.startuphub.ai/ai-news/artificial-intelligence/2026/hinton-wants-fda-rules-for-ai-calls-0-risk-silly) has pressed about systems acting without human control sits alongside financial stability risks as the White House pushes hard to compete with China. The unanswered risk is duration. Gensler said chips bought with this debt may have only four to seven year useful lives and the 2026 generation will be far less valuable by 2032, while Oliver Wyman estimates $6 trillion in projected AI capex through 2030 could create a credit buildup larger than all broadband investment since the internet began, according to [Oliver Wyman](https://www.oliverwyman.com/our-expertise/insights/2026/jan/impact-ai-bubble-burst-on-global-financial-markets.html), and no one on the discussion mapped where the private credit and insurance holdings for that debt ultimately sit. --- Original analysis from [startuphub.ai](https://www.startuphub.ai), the #1 AI startup directory. © StartupHub.ai.
