Synergy Research: Amazon, Microsoft, and Google accounted for 65% of the $53B in global cloud spending in Q1 2022, up from 52% in 2018
Three companies account for about two-thirds of cloud spending and are using their size to maintain their hold on rapidly growing market Tweets: @jeffnolan Tweets: Jeff Nolan / @jeffnolan : makes sense. Everyone buys there cloud infrastructure from these 3 companies https://twitter.com/...
Context & Ripple Effects
Synergy's quarterly trackers have been documenting this concentration for years: cloud spending scaled from the $29B pandemic quarter of Q1 2020 to $41.8B in Q1 2021 and $53B in Q1 2022, with AWS steady at roughly 32% share throughout while Azure climbed from 18% to 19% and Google from 7%. What the new data point adds is the combined picture: the top three's share rose from 52% in 2018 to 65%, meaning growth itself is accruing disproportionately to the incumbents.
The WSJ's framing — the three are using their size to hold the market — connects to the capital side of the ledger: RBC's tally of $63.8B in 2017 capex across 19 cloud operators showed early on that this is a business where scale begets scale, and the share data suggests only three operators have kept pace.
First-order effects
- Enterprise buyers face a shrinking set of realistic infrastructure vendors, since two-thirds of spend flows to Amazon, Microsoft, and Google and the fastest-growing workloads land there by default.
- AWS's ~32% share has been stable since 2020 while the total market nearly doubled — Amazon is capturing volume at the same rate as the market grows, leaving Microsoft and Google to fight over the remainder.
Second-order effects
- Rivals outside the top three must match hyperscale capex to stay relevant, a race RBC's operator spending data showed was already thinning the field of credible competitors.
- Microsoft and Google respond by buying share with growth — their combined gains (Azure 18% to 23%, Google 7% to 10% across Synergy's 2020–2023 readings) come at the expense of everyone ranked fourth and below, not Amazon.
Third-order effects
- The pattern holds in later Synergy data: growth decelerated from 32% to 19% YoY by Q1 2023 while the top three's share stayed intact, pointing to a maturing market that consolidates into a stable three-firm oligopoly rather than fragmenting.
- By Q1 2024, Altimeter's reading shows the contest is now internal to the trio — Azure at 25% and Google at 11% against AWS at 31% — meaning the structural question shifts from whether challengers can enter to how share rotates among the incumbents.
The trend: Cloud infrastructure is consolidating into a three-firm oligopoly whose internal share rotates — Microsoft and Google gaining on Amazon — while the combined hold on enterprise spend tightens with each market-size doubling.
