The US stock market is at 235% of GDP — the Warren Buffett Index all-time high — with trailing P/E ratios near 30x and the Shiller CAPE also at historic highs. Gensler says every measure tells the same story.

By every measure Gensler names — the Warren Buffett Index (235% of GDP), trailing P/E ratios (near 30x), the Shiller CAPE — US stock market valuations are at or near historic highs. The AI investment wave driving this is extraordinary in scale: capital spending on data centers, chips, memory, and related infrastructure has grown from roughly $140 billion to $750 billion in just three years — a nearly fivefold increase. In 2026, that $750 billion equals about 2.5% of US GDP; it's projected to hit over $1 trillion and more than 3% of GDP by next year. Gensler notes this is larger, as a share of GDP, than almost any prior general-purpose technology investment wave, with the partial exception of post-Civil War railroads, which peaked at 6–7% before triggering the crash of the 1870s. He also contextualizes Citadel's headline that the bottom 50% of US households now hold a record $600 billion in equities — but points out this is less than 1% of the $80 trillion total market, calling it 'messaging' rather than a substantive democratization of market access.

Perfecting a product for months guarantees nothing. The Starter Story founder pressed publish on his meticulously crafted site and watched zero users arrive — the brutal lesson every founder needs to hear.
The world's best companies didn't buy their first customers — they went to where those customers already were and created content for them. Free channels like Reddit aren't a hack; they're the actual strategy.
A single link post on Reddit drove 100 visitors to Starter Story in minutes. Then the moderators deleted it. That deletion became the catalyst for a far smarter strategy.
Redditors hate spam — so stop looking like spam. By putting all his content directly into a self-post and adding only a tiny footer link, the Starter Story founder made his marketing invisible to moderators and irresistible to readers.
Going from zero engagement to hundreds of upvotes overnight isn't luck — it's product-market fit. When your content makes strangers ask for more, you've found something real.
Reddit traffic is borrowed. An email list is owned. The Starter Story founder built tens of thousands of subscribers before Reddit banned him — meaning the platform's death sentence didn't matter.
After interviewing thousands of successful founders, one pattern repeats: they all built something, got ignored, and then figured out distribution. Building was never the hard part — getting in front of customers was.
