🚨 BREAKING: Warren Buffett and Peter Thiel just did the same thing at the same time.
They sold everything.
And nobody's connecting the dots.
Warren Buffett retired as CEO of Berkshire Hathaway on December 31, 2025.
His final act?
Berkshire's Q4 report dropped last week.
Net seller of stocks for 13 straight quarters.
$187 billion in net sales since late 2022.
Not trimming. Not rotating.
Selling. Consistently. For over three years.
Then there's Peter Thiel.
Co-founder of PayPal. First outside investor in Facebook. Co-founder of Palantir.
One of the most plugged-in investors in Silicon Valley history.
His hedge fund, Thiel Macro, just filed its Q4 13F.
He liquidated everything.
Tesla. Microsoft. Apple. Gone.
$74 million in public equities.
Zero.
Let that sink in.
Two of the most successful investors alive, one a value legend, one a tech insider, both went to cash at the same time.
That's not a coincidence.
Here's what they're both seeing:
The S&P 500's CAPE ratio averaged 39.8 in February 2026.
That's the highest reading since the dot-com crash in October 2000.
The CAPE ratio has only topped 39 during 26 months in the index's entire history since 1957.
We're in one of those months right now.
Here's why that matters:
Every single time the S&P 500's monthly CAPE ratio has exceeded 39, the index has declined by an average of 30% over the next three years.
Not sometimes. Every time.
And the Buffett Indicator?
Total U.S. market cap as a percentage of GDP hit an all-time record of over 221% in January 2026.
Higher than the dot-com bubble.
Higher than 2008.
Higher than any point in recorded history.
Buffett himself popularized this metric, calling it "probably the best single measure of where valuations stand at any given moment."
And it's screaming.
Back to Berkshire's report.
In 2018, Buffett told CNBC:
"It's hard to think of very many months when we haven't been a net buyer of stocks."
That was the old Buffett.
The Buffett who left?
Net seller. Every quarter. For three straight years.
He started new positions in UnitedHealth, Alphabet, and The New York Times last year.
But he sold far more than he bought.
The pile of cash he's leaving his successor Greg Abel?
$373 billion.
Not deployed. Not invested.
Sitting there.
Waiting.
Buffett doesn't hoard cash because he's scared.
He hoards cash because he can't find anything worth buying at current prices.
That's the warning.
Now look at Thiel's moves in sequence:
Q3 2025: Sold Nvidia and Vistra. Trimmed Tesla.
Q4 2025: Sold the rest. Apple. Microsoft. Tesla. Everything.
One quarter earlier, Apple and Microsoft alone represented 61% of his fund.
High conviction. Then gone.
Thiel didn't panic sell.
He systematically exited over two quarters.
That's not fear. That's a thesis.
His thesis: the market has priced in a future that hasn't happened yet.
AI spending is real. But the returns on that spending aren't proven.
Valuations assume the bull case. Every time.
And when the bull case doesn't materialize fast enough?
The correction comes hard.
Buffett lived through 1929, 1987, 2000, and 2008.
He knows what overvalued markets look like from the inside.
Thiel built and sold companies at the peak of multiple tech cycles.
He knows when hype exceeds fundamentals.
Both of them are saying the same thing right now:
The price is wrong.
Here's what retail investors are doing instead:
Buying the dip on AI stocks.
Piling into software ETFs down 20%.
Treating record valuations like a sale.
The Buffett Indicator is at 221%.
The CAPE ratio is at dot-com levels.
The two smartest money in the room just went to cash.
And retail is still buying.
Buffett didn't get rich by doing what everyone else was doing.
Thiel didn't get rich by ignoring the signals everyone else was missing.
They're both sending the same signal right now.
The question is whether you're paying attention.
we're making @blocks smaller today. here's my note to the company.
####
today we're making one of the hardest decisions in the history of our company: we're reducing our organization by nearly half, from over 10,000 people to just under 6,000. that means over 4,000 of you are being asked to leave or entering into consultation. i'll be straight about what's happening, why, and what it means for everyone.
first off, if you're one of the people affected, you'll receive your salary for 20 weeks + 1 week per year of tenure, equity vested through the end of may, 6 months of health care, your corporate devices, and $5,000 to put toward whatever you need to help you in this transition (if you’re outside the U.S. you’ll receive similar support but exact details are going to vary based on local requirements). i want you to know that before anything else. everyone will be notified today, whether you're being asked to leave, entering consultation, or asked to stay.
we're not making this decision because we're in trouble. our business is strong. gross profit continues to grow, we continue to serve more and more customers, and profitability is improving. but something has changed. we're already seeing that the intelligence tools we’re creating and using, paired with smaller and flatter teams, are enabling a new way of working which fundamentally changes what it means to build and run a company. and that's accelerating rapidly.
i had two options: cut gradually over months or years as this shift plays out, or be honest about where we are and act on it now. i chose the latter. repeated rounds of cuts are destructive to morale, to focus, and to the trust that customers and shareholders place in our ability to lead. i'd rather take a hard, clear action now and build from a position we believe in than manage a slow reduction of people toward the same outcome. a smaller company also gives us the space to grow our business the right way, on our own terms, instead of constantly reacting to market pressures.
a decision at this scale carries risk. but so does standing still. we've done a full review to determine the roles and people we require to reliably grow the business from here, and we've pressure-tested those decisions from multiple angles. i accept that we may have gotten some of them wrong, and we've built in flexibility to account for that, and do the right thing for our customers.
we're not going to just disappear people from slack and email and pretend they were never here. communication channels will stay open through thursday evening (pacific) so everyone can say goodbye properly, and share whatever you wish. i'll also be hosting a live video session to thank everyone at 3:35pm pacific. i know doing it this way might feel awkward. i'd rather it feel awkward and human than efficient and cold.
to those of you leaving…i’m grateful for you, and i’m sorry to put you through this. you built what this company is today. that's a fact that i'll honor forever. this decision is not a reflection of what you contributed. you will be a great contributor to any organization going forward.
to those staying…i made this decision, and i'll own it. what i'm asking of you is to build with me. we're going to build this company with intelligence at the core of everything we do. how we work, how we create, how we serve our customers. our customers will feel this shift too, and we're going to help them navigate it: towards a future where they can build their own features directly, composed of our capabilities and served through our interfaces. that's what i'm focused on now. expect a note from me tomorrow.
