Alphabet, Amazon, Meta, and Microsoft are collectively investing about $650 billion in AI infrastructure in 2026, marking a 60% jump from $410 billion in 2025. The spending spree is forcing these tech giants to slash stock buybacks to their lowest levels since 2019, while Nvidia reports record 75% gross margins fueling both opportunity and concern about sustainability.

Big Tech AI Spending Reaches Historic $650 Billion in 2026

The AI investment landscape has entered a new phase of intensity as Alphabet, Amazon, Meta, and Microsoft collectively pour approximately $650 billion into AI infrastructure this year, according to analysis by Bridgewater Associates

. This represents a sharp increase of about 60% from $410 billion in 2025, underscoring how rapidly Big Tech AI spending has accelerated. Bridgewater co-chief investment officer Greg Jensen characterized this as a "more dangerous phase" marked by exponentially rising investments in physical infrastructure and growing reliance on outside capital.

The scale of AI capital expenditure is reshaping how these companies allocate resources. Meta plans to spend up to $135 billion this year compared to $72 billion in 2025, while Google's budget could reach $185 billion, up from $91 billion the previous year

. Jensen noted that "compute demand continues to significantly outpace supply, driving hyperscalers to invest even more rapidly to try to someday get ahead of the demand"

Stock Buybacks Hit Lowest Point Since 2019

To fund this unprecedented hyperscalers AI investment, Big Tech companies have drastically curtailed stock buybacks. Last quarter, Alphabet, Microsoft, Amazon, and Meta spent the least on combined share repurchases than in any quarter since 2019

. Alphabet and Microsoft spent roughly $11 billion on buybacks, while Amazon and Meta held off entirely

. Amazon hasn't bought back stock since 2022.

This shift from returning cash to shareholders to investing in data center infrastructure represents a fundamental change in Big Tech's financial strategy. The combined free cash flow for these four companies is projected to fall 64% over the next four quarters to about $96 billion from roughly $270 billion in 2025

. "In the history of the world, probably nobody has been able to make more money in asset-light businesses than these companies," said Kim Forrest, chief investment officer at Bokeh Capital Partners. "They're throwing that to the wind because they're all caught up in some kind of race"

Nvidia Posts 75% Gross Margin Amid AI Chip Market Dominance

Nvidia delivered blockbuster results with adjusted gross margin reaching 75.2% in the November-January period, the highest since the second half of 2024

Huang defended the sustainability of this spending trajectory, stating that "the amount of token generation capability that the world needs is a lot more than $700 billion"

. He pointed to agentic AI as a new wave of compute demand, noting that "agentic AI has reached an inflection point, and it literally happened in the last 2 or 3 months"

Competition Intensifies as Rivals Target Nvidia's Margins

Nvidia's extraordinary profitability has attracted fierce competition in the AI chip market. Meta and Advanced Micro Devices announced a "double-digit billions" deal for processors for data centers, while OpenAI negotiated something similar in October

. According to Bloomberg Intelligence, the average selling price per unit of a Google TPU is $8,000 to $10,000 compared with $23,000 or more for Nvidia's H100 chip or $27,000 and above for its newer Blackwell system

Alphabet's stock price rose when its Tensor Processing Units began handling a significant portion of workloads for Google Cloud clients and its own AI services like Gemini, while Amazon notched a win by bringing on Anthropic as a client for its own AI chips

Downside Risks Emerge as Spending Outpaces Returns

Bridgewater's Jensen warned that the scale of spending is creating significant downside risks if anything goes wrong

2

. Companies like Anthropic and OpenAI will need major product breakthroughs to secure backing for massive final fundraisings ahead of potential IPOs. "Without a credible path to outsized profits, they could struggle to justify lofty valuations and heavy capital demands," he noted

.

The spending boom is also creating ripple effects across the economy. Bridgewater estimates tech investment added about 50 basis points to U.S. GDP growth in 2025 and could provide around 100 basis points of support this year

2

. However, the surge may also lift inflation in technology and communications equipment and push up electricity prices in some regions

5

. A severe stock market correction could undermine growth and limit companies' ability to raise capital, similar to the Dot-com bubble in 2000
