Alphabet said Monday it will raise $80 billion in equity to pay for AI infrastructure, telling investors that demand for its AI products from companies and consumers is running past what it can actually supply. Berkshire Hathaway is in for $10 billion of it.
Even Google is short on compute
That admission, that the supply isn't there, is the part worth sitting with. This is the company that designs its own TPUs and runs some of the largest data centers on the planet, and it's still telling Wall Street it can't keep up. The SEC filing puts it plainly: customer demand is exceeding available supply.
The crunch shows up internally too. Back in November, Google's infrastructure lead told employees the company has to double its AI serving capacity roughly every six months to meet demand, according to CNBC reporting. Pichai called compute the bottleneck and pointed at Veo, the video tool, as an example of demand the company couldn't fully serve.
Where the money comes from
The structure is more interesting than the headline number. Of the $80 billion, $30 billion comes through concurrent public offerings, split between convertible preferred stock and common shares. Another $40 billion is an at-the-market program slated to start in Q3 2026, and a chunk of that, around $30 billion, is earmarked for employee tax obligations on vesting stock rather than data centers. So the clean "$80 billion for AI" framing is a little softer than it sounds.
Then there's Berkshire. The firm is buying $5 billion in Class A shares at $351.81 and $5 billion in Class C at $348.20, adding to a position it started building in late 2025. Warren Buffett's outfit historically avoided big tech, so the vote of confidence carries some weight, though it's a private placement at a set price, not a bet placed on the open market.
"By leaning into equity, Alphabet is bringing in permanent capital rather than burdening a balance sheet already absorbing record capex," Mergermarket's Troy Hooper told Al Jazeera. Which is the polite way of saying the spending is enormous enough that even Alphabet's cash flow needs help.
So why not just pay cash?
Alphabet generated roughly $174 billion in operating cash flow over the trailing 12 months, so this isn't a company scraping the bottom. The equity raise is about pace. The 2026 capex target sits between $175 and $185 billion in the original guidance, later nudged up toward $180-190 billion at the Q1 call, either way more than double what it spent in 2025. Funding that entirely from operations would gut the balance sheet, and Alphabet would rather keep the cushion.
The numbers around demand are real enough to take seriously. Google Cloud revenue grew 63% year-over-year in Q1 2026 to $20 billion, and the backlog of contracted future revenue nearly doubled to more than $460 billion. That backlog is the clearest signal here. It's money customers have already committed that Google can't recognize until it has the capacity to deliver.
The at-the-market program is expected to begin in the third quarter. That's the next concrete marker to watch.
