Tech Giants Commit $300 Billion to Data Centres — Almost Half Their Combined 2026 EBITDA

Amazon.com, Inc. (AMZN), Alphabet Inc. (GOOG), Meta Platforms, Inc. (META), Broadcom Inc. (AVGO), Oracle Corporation (ORCL) and SpaceX, Inc. (SPCX) have collectively committed $300 billion in data-centre financing — a sum equal to almost half their estimated combined 2026 EBITDA of $663 billion — in what amounts to the most capital-intensive infrastructure build-out in the history of the technology sector.

The scale of the commitment reframes the AI infrastructure race as a balance-sheet event, not merely an engineering one. With half of a full year's earnings power pledged to physical plant, the group's capacity to absorb cost overruns, regulatory delays or a demand slowdown is being tested in real time — and the risks are already materialising on two continents.

What happened

The $300 billion financing figure spans the six companies' combined data-centre commitments and sits against an estimated group EBITDA of $663 billion for 2026. The ratio of 45% additional Capex/ Ebitda underscores how deeply capital expenditure has penetrated the earnings base of even the most profitable technology franchises. Alphabet, Meta Platforms and Amazon.com each raised their capital-expenditure guidance during recent earnings calls; collectively, the four largest US hyperscalers — including Microsoft — now expect capex to exceed $380 billion in 2026 alone.

Why it matters

AI infrastructure spending at this scale is reshaping capital allocation across the technology sector, pulling investment away from software and consumer products toward power, cooling, fibre and silicon. The commitment also concentrates execution risk: delays in permitting, grid connection or environmental approval can strand billions in planned expenditure.

Those risks are no longer hypothetical. On 7 October 2026, San Francisco's Board of Supervisors unanimously approved a 45-day moratorium on new data centres, effective immediately, citing water consumption, electricity costs and environmental-justice concerns in the Bayview-Hunters Point neighbourhood. The pause can be extended for roughly two years as officials weigh permanent restrictions — a significant constraint in a city that is home to OpenAI and Anthropic.

In Europe, Finland's Licensing and Supervision Agency ordered Alphabet to stop forest clearing at two data-centre sites — in Muhos and Kajaani — pending mandatory environmental-impact assessments, with a response deadline of 14 October 2026. Alphabet stated it intends to follow the agency's guidance; the company's broader €13 billion investment commitment in Finland remains in place.

What to watch next

• Alphabet (GOOG) next earnings report: 28 October 2026 — capex trajectory and any revised infrastructure guidance will be closely watched.

• Meta Platforms (META) next earnings report: 28 October 2026 — investors will scrutinise whether EPS pressure persists alongside rising infrastructure spend.

• Amazon.com (AMZN) next earnings report: 29 October 2026 — AWS margin and data-centre capex commitments are the key metrics.

• Alphabet's response to Finland's Licensing and Supervision Agency is due by 14 October 2026; the outcome could affect the timeline of its €13 billion European build-out.

• San Francisco's 45-day moratorium, in effect from 7 October 2026, can be extended for up to roughly two years — a potential template for other municipalities.
