with Jeremy Grantham

TL;DR
Jeremy Grantham argues the current AI-driven stock market is the biggest bubble in American history and is weeks away from bursting — dwarfing the dot-com and housing crashes he previously called. He recommends abandoning US equities in favour of international and emerging market stocks, resources, and cash, while warning that a parallel fertility crisis driven by microplastics and pesticides poses an existential civilisational risk that is being almost entirely ignored.
Key Moments
Jeremy Grantham
“The AI bubble is the broadest and most extreme in American history. We had the South Sea Bubble, we had the dot-com, we had the housing bubble — this one has characteristics of all three at the same time.”
Grantham making his central case for why the current moment is uniquely dangerous for investors, shortly after the episode opens on the AI bubble question.

“AI will change the world — I have no doubt about that. But changing the world does not mean the companies involved make money. The railroads changed the world and most of them went bankrupt. The internet changed the world and most of the dot-coms went to zero.”

“Wall Street has never, ever warned you when to get out of the market. Not once in history. Their business model depends on you staying invested — the day you sell is the day they stop making money from you.”
Grantham explaining why retail investors cannot rely on brokers or advisors to protect them ahead of a crash, around the investing strategy discussion.

“House prices need to fall thirty percent to get back to any kind of affordability that a normal working person can access. Until that happens, you have a society that is fracturing — because the young simply cannot get in.”
Grantham discussing the housing market and its social consequences during the property investment segment.

“Sperm counts have fallen fifty percent in fifty years. If you extrapolate that line, you get to zero. That is not a metaphor — that is the data. And almost nobody in power is talking about it.”
Grantham shifting to the fertility crisis segment, warning about declining male reproductive health driven by chemical exposure.

Takeaways
1
US stocks are uniquely dangerous right now Grantham argues US equities are more overvalued than at any prior bubble peak on multiple measures. His recommended alternative is a portfolio weighted toward international developed markets, emerging markets, and resource stocks — areas he sees as genuinely cheap relative to fundamentals.
2
Sperm counts are on a trajectory toward zero Measured sperm counts have dropped roughly 50% over the past 50 years. Grantham links this to ubiquitous exposure to endocrine-disrupting chemicals — pesticides, microplastics, and synthetic compounds in cosmetics and food packaging — and warns the trend shows no sign of reversing without regulatory intervention.
3
Reduce chemical exposure with practical household swaps Grantham recommends avoiding plastics in food contact (especially when heated), choosing organic produce for the highest-pesticide crops, and switching to cosmetics and personal care products that avoid parabens and phthalates. These steps won't eliminate exposure but meaningfully reduce the body burden of the worst compounds.
4
AI profits won't follow AI hype History shows that transformative technologies destroy more incumbent value than they create for investors — railroads, the internet, and electricity all changed the world while wiping out most early investors. Grantham expects the same dynamic to play out with AI, with intense competition compressing margins across the sector.
5
Your financial advisor is structurally incentivised to keep you invested Wall Street's revenue is tied to assets under management — advisors earn fees only while you hold. This means no mainstream institution has ever issued a clear 'sell everything' warning before a crash, and none will this time either. Grantham says investors must seek independent, non-commission-based research.
6
Property still needs a 30% price correction to be affordable Grantham contends that current house prices are still fundamentally misaligned with wages and rental yields, and that a 30% nominal decline is necessary — not a prediction of an imminent crash, but a statement about where fair value sits. Until that correction happens, he views residential property in most Western markets as a poor risk-adjusted investment.
7
Wealth inequality is a historically proven societal destabiliser Grantham draws on historical data showing that extreme concentrations of wealth reliably precede social and political instability. He argues the current US Gini coefficient and asset-price inflation have transferred enormous wealth from younger to older generations, and that without tax or policy correction, social cohesion deteriorates.
