Alphabet, the Mountain View parent company of Google, said it will raise approximately $80 billion in equity to fund a multi-year build-out of AI infrastructure, with Warren Buffett's Berkshire Hathaway taking $10 billion of the deal. The financing announced June 1-2, 2026 lands as Alphabet's largest equity raise on record and one of the biggest single AI-infrastructure financings of the cycle.
How the $80 billion breaks down
Alphabet structured the raise in two parts. The first $30 billion comes through underwritten offerings, including roughly $15 billion in depositary shares representing mandatory convertible preferred stock. The remaining $40 billion will be sold through an at-the-market (ATM) program covering Class A and Class C shares, expected to begin in the third quarter. The mix lets Alphabet pull forward capital quickly without flooding the market in any single window.
Berkshire's $10B vote of confidence
Berkshire Hathaway agreed to take $10 billion of the issuance, the largest disclosed buyer. Berkshire began building a position in Alphabet during Q3 2025 and has now turned an opportunistic equity stake into a direct, anchored capital commitment. For a company whose chairman has historically been cautious on technology bets, the size of the check reads as a strong endorsement of long-duration AI capex.
Why now: demand exceeds available compute
Alphabet's filings cite "general corporate purposes, including capital expenditures to scale AI infrastructure and global compute." Management has repeatedly said demand for Google's AI products and services now exceeds available capacity — a structural constraint that is forcing Google Cloud and DeepMind to add data centers, accelerators and power contracts faster than internal cash flow alone can fund.
Context in the hyperscaler arms race
The raise is the latest signal that capital intensity in the AI buildout is migrating from the income statement to the balance sheet. The five largest US cloud and AI infrastructure providers — Microsoft, Alphabet, Amazon, Meta and Oracle — have collectively committed between $660 billion and $690 billion in 2026 capex. Alphabet's move follows comparable financings across the sector, including SoftBank's $75 billion France data center push with Schneider Electric, and the recent $410M DriveNets Series D for AI networking fabric.
Read-through for AI compute markets
Adding $80 billion of equity capacity gives Alphabet additional runway to commit to multi-gigawatt power agreements, custom TPU and accelerator orders, and long-lead-time fab and HBM allocations. Combined with industry-wide signals such as Anthropic's confidential IPO filing, the deal underscores that public-market investors are willing to underwrite the buildout at a scale unseen outside of the energy and telecom cycles. The disclosure also makes Alphabet's AI capex plans more durable through any near-term ad-revenue softness.
