Amazon has unleashed "Project Rainier," a colossal $11 billion initiative to power Anthropic’s Claude AI models using over a million Trainium2 chips. Located on a sprawling 485-hectare site in Indiana, this dedicated AI training hub is already operational with 500,000 chips live—and Anthropic is doubling down on its AWS partnership. Meanwhile, Amazon and Google have poured a combined $11 billion into Anthropic, signaling a high-stakes race in AI infrastructure. With Claude’s revenue hitting $500 million in just eight weeks and enterprise demand skyrocketing, the battle for AI supremacy is heating up. Here’s the inside story.
What is Project Rainier, and Why Does It Matter?
Amazon’s Project Rainier isn’t some futuristic concept—it’s apowerhouse. Imagine converting cornfields into data centers almost overnight (seriously, AWS CEO Matt Garman described it that way). This Indiana-based beast spans 485 hectares near Lake Michigan and runs exclusively on Amazon’s custom Trainium2 chips. Currently, 500,000 chips are humming away, with plans to scale beyond a million by year-end. For context, that’s enough processing muscle to make your laptop weep. Anthropic’s models, including Claude, are being trained here, split across Nvidia GPUs, Google TPUs, and Amazon’s chips—each handling specialized tasks like research, training, and inference. It’s aballet at unprecedented scale.
Who’s Bankrolling This AI Arms Race?
Follow the money: Amazon has committed $8 billion, Google dropped $3 billion, and Anthropic itself is reinvesting heavily. But here’s the kicker—Anthropic isn’t putting all its eggs in one basket. Last week, it inked a deal with Google for custom TPUs worth "tens of billions" (exact figures are hush-hush). AWS’s Prasad Kalyanaraman put it bluntly: controlling the infrastructure stack from the ground up is non-negotiable for AI dominance. Meanwhile, skeptics whisper about energy demands and community pushback, but Amazon’s decades of logistical prowess (think HQ2 and distribution hubs) give it a unique edge in navigating these hurdles.
How Fast Is Anthropic Growing?
Hold onto your hats: Claude now supports 300,000 businesses—ain two years. Enterprise clients (those with $100K+ annual revenue) grew 7x in 12 months. Then there’s Claude Code, which racked up $500 million in annualized revenue withinof launch. Mike Krieger, Anthropic’s Product Lead, admits demand is so fierce they’ll "need every ounce of processing power" Rainier can provide. Yet, despite rumors, Amazon isn’t buying Anthropic—both sides insist their current alliance works just fine.
What’s Next for AI Infrastructure?
Josh Sallabedra, Rainier’s site lead with 14 years at Amazon, says he’s "never seen the company MOVE this fast." Garman calls it a "light-speed transition from theory to reality." But the real story? This isn’t just about bigger data centers—it’s a fundamental shift in how AI scales. Anthropic’s multi-chip strategy avoids vendor lock-in, while AWS bets on vertical integration. One thing’s certain: as Claude’s corporate user base explodes, the pressure to deliver flawless, low-latency AI will only intensify. And with Rainier live, Amazon just fired a loud shot across Nvidia’s and Google’s bows.
