Berkshire Just Made Alphabet a No. 3 Holding. Judge It Like the Cash Machine It Is

Berkshire Hathaway's latest 13F told a quiet but striking story: in the second quarter of 2026 the firm poured roughly $17 billion more into Alphabet, ending June with about 106 million shares worth around $37.9 billion — an 83% jump in the stake in a single quarter that made Google's parent Berkshire's third-largest U.S. holding, behind only Apple and American Express.

That headline matters to a retail investor for one reason: the most cash-flow-obsessed investor there has ever been just moved one of its biggest bets onto a company that, in the same stretch, did something it had never done before — reported a negative quarter of free cash flow.

The collision of those two facts is the story. Berkshire is betting that Google's dominance survives the artificial-intelligence buildout that is currently eating its cash. The question is whether the market, or your portfolio, should bet the same way.

A toll booth that prints money

Start with the cash flow, because that is where any judgment about Alphabet has to begin. Google controls roughly 91% of global search traffic,Google controls roughly 91% of global search traffic and that near-monopoly on the internet's front door converts attention into advertising revenue of about $307 billion a year.converts attention into advertising revenue of about $307 billion a year The economics are hard to overstate: roughly 38% EBITDA margins, about a third of revenue falling to operating income, and operating cash flow of roughly $186 billion over the trailing twelve months.

Think of search as a toll bridge. The tolls have been rising for two decades, the bridge has never been cheaper to maintain relative to what it collects, and there is no competitor with anything close to the same traffic. That is durable, fee-like, predictable cash flow — the kind a value investor builds conviction on, because there is little about the day-to-day business that can surprise you.

That first negative FCF quarter, audited

Here is the number the bears anchor on, and it is real. In the second quarter of 2026 Alphabet reported negative free cash flow of about $5.9 billion — its first ever — while quarterly capital spending doubled to roughly $44.9 billion,In the second quarter of 2026 Alphabet reported negative free cash flow of about $5.9 billion and management pushed its 2026 spending outlook $15 billion higher.pushed its 2026 spending outlook $15 billion higher Headlines have followed the obvious arc: in the AI era, Google's online dominance is "showing signs of cracking," as users drift toward chatbots and AI-first search.Google's online dominance is "showing signs of cracking"

Audit what that number actually measures, though. The free cash flow did not fall because the toll bridge stopped collecting. Alphabet still generated about $186 billion of operating cash flow over the past year; what it did was choose to reinvest a large share of it into data centers and AI compute. That is the difference between a business deteriorating and a business investing more aggressively, and the panic conflates the two.

The balance sheet absorbed the spending without strain — the company sits on roughly $144 billion of net cash against minimal debt — and the investment is already showing up on the revenue side. Google Cloud grew 82% year over year in the quarter, to about $24.8 billion.Google Cloud grew 82% year over year in the quarter, to about $24.8 billion The cash isn't vanishing; it is being redirected, and for now it is buying compounding growth rather than just subsidizing a dying franchise.

The honest rub: the margin of safety

Now let's talk about valuation, because this is where the value discipline parts ways with the stampede. Berkshire did get a bargain price — the initial roughly $10 billion stake, taken about fifteen months ago, came through a private placement at a 6.5% discount to the market.came through a private placement at a 6.5% discount to the market That is the kind of entry price a retail buyer simply cannot reproduce.

At today's levels Alphabet trades around a $4 trillion market value, roughly 23 times enterprise value to EBITDA and about 32 times forward earnings. That is not cheap against the rest of big tech: Meta sits near 15 times, Amazon near 16, Microsoft near 19. And the stock is up roughly 36% over the past year. After a move that size, with Berkshire's endorsement now public knowledge, the easy money has been made and the cushion against a wrong guess is thin.

So what Berkshire did was not "buy a cheap stock." Abel has said the firm's own visibility into how its portfolio companies use AI drove the bet, and he called Alphabet a "significant player" in AI.Abel has said the firm's own visibility into how its portfolio companies use AI drove the bet That is a vote for durability and optionality, not for a discount.

The judgment that follows is straightforward. The toll booth is real, and the AI-panic narrative overstates the near-term danger to the cash machine. But the fat margin of safety was captured at the private-placement price, not at today's multiple. Judge Alphabet as the dominant generator of cash that it is, and recognize the current price as full tuition on that quality. The question that will decide the next leg is whether that record capital spending compounds into returns before AI-driven search economics chip away at the toll bridge. That unresolved divergence is why the stock will swing; the cash flow is what makes it safe to hold through the swing.
