If 2023 was the year AI went mainstream and 2024 was the year it went enterprise, 2025 was the year it went colossal. This was the moment when artificial intelligence stopped being framed as software and started being treated like critical global infrastructure, on the scale of electricity, oil, or the internet itself.
Companies weren’t just buying startups or funding models anymore; they were locking in power generation, building continent-scale data centers, and signing decade-long compute contracts worth hundreds of billions of dollars. The deals of 2025 reveal a simple truth: whoever controls AI capacity controls the future of tech, defense, media, and the global economy.
What follows are the ten biggest AI deals of 2025, ranked roughly by size and strategic impact. This list includes acquisitions, infrastructure commitments, equity stakes, and long-term compute agreements—because in 2025, “AI deals” meant far more than traditional M&A.
1. OpenAI, SoftBank & Oracle Launch “Stargate” — ~$500B
The single largest AI commitment ever announced. OpenAI partnered with SoftBank and Oracle to create Stargate, a massive U.S.-based AI infrastructure initiative aimed at building data centers, securing energy supply, and guaranteeing long-term compute for frontier models. While not all capital is deployed upfront, the planned scale—up to half a trillion dollars—redefined what an “AI deal” even means.
2. OpenAI’s Long-Term Compute Agreement with Oracle — ~$300B
Separate from Stargate, OpenAI signed a multi-year agreement to buy cloud compute and power capacity from Oracle at a staggering scale. This deal effectively guaranteed OpenAI access to vast amounts of compute for future model training and deployment, while transforming Oracle into a serious AI infrastructure player almost overnight.

3. Nvidia’s Strategic Investment and Partnership with OpenAI — ~$100B
Nvidia doubled down on its dominance by committing capital, hardware priority, and deep technical collaboration with OpenAI. Valued at roughly $100 billion when infrastructure and future commitments are included, the deal tightly bound the world’s leading AI model company to the world’s most important AI chipmaker.
4. Anthropic’s AI Infrastructure Buildout — ~$50B
Anthropic announced plans to spend around $50 billion on AI infrastructure, including data centers, compute contracts, and energy. Rather than relying solely on partners, Anthropic moved aggressively to secure its own long-term capacity, signaling that frontier AI labs now think like utilities, not startups.
5. Amazon’s AI Data Center Expansion — ~$50B
Amazon committed roughly $50 billion toward AI-focused data centers and high-performance compute, largely to support AWS customers running large models. While framed as infrastructure spending rather than a single deal, the commitment reshaped the competitive landscape for cloud-based AI.
6. BlackRock, Microsoft & Nvidia Acquire Aligned Data Centers — ~$40B
A consortium led by BlackRock, Microsoft, and Nvidia acquired Aligned Data Centers in a deal valued around $40 billion. The move reflected growing interest from Wall Street in owning the physical backbone of AI—and treating data centers as long-term strategic assets, not just real estate.
7. OpenAI and Amazon Web Services Partnership — ~$38B
In a notable twist, OpenAI expanded beyond Microsoft by signing a major multi-year partnership with AWS. Valued at roughly $38 billion, the deal diversified OpenAI’s cloud dependencies and underscored how even the biggest AI players no longer rely on a single provider.
8. Alphabet’s Acquisition of Wiz — ~$32B
Google’s parent company Alphabet acquired cloud security startup Wiz for about $32 billion. While not a pure-play AI company, Wiz’s AI-driven security tooling was seen as critical infrastructure for enterprise AI adoption, making this one of the year’s most important AI-adjacent acquisitions.

9. Google’s AI Infrastructure and Data Center Investment — ~$25B
Google committed $25 billion toward AI infrastructure and data centers through the latter half of the decade. Like Amazon’s move, this wasn’t a single acquisition—but its scale and AI focus made it one of the most consequential commitments of the year.
10. Meta’s Strategic Stake in Scale AI — ~$14-15B
Meta acquired a roughly 49% stake in Scale AI, the company behind some of the most important data labeling and model evaluation pipelines in the industry. The deal gave Meta tighter control over a critical layer of the AI stack: high-quality training data.
What these deals say about the future of AI
Taken together, the biggest AI deals of 2025 tell a clear story: AI has entered its infrastructure era. The battle is no longer just about smarter models—it’s about who controls compute, power, data centers, and supply chains over the next ten years. Tech giants are locking in capacity the way nations once locked in oil reserves, while financial firms are treating AI infrastructure as a new asset class entirely. These deals also hint at a more consolidated future, where only a handful of players can afford to operate at the frontier.
If this trajectory continues, 2025 will be remembered as the year AI stopped being a product and became a permanent layer of the global economy. The companies that made these deals weren’t just buying technology—they were buying leverage over the future.
