Amazon's Anthropic Bet Pays Off Big: $16.8B Pre-Tax Gain as AI Startup Files for IPO

Quick Take

Amazon's strategic bet on AI startup Anthropic is delivering outsized returns. With Anthropic filing confidentially for an IPO on June 1 at a $965 billion valuation, Amazon's stake — worth an estimated $135 billion to $160 billion — has already generated $16.8 billion in pre-tax gains in Q1 alone, more than 40% of Amazon's pre-tax income for the period. This is a game-changer for Amazon's AI thesis and its bottom line.

The Big Story: Anthropic's IPO and Amazon's Windfall

Anthropic, the company behind the Claude AI models, confidentially filed to go public on June 1 after a funding round that raised $65 billion at a $965 billion valuation. The company's annualized revenue is approaching $50 billion, up from just $4 billion last July — a staggering 12.5x growth in under a year. Expectations call for $10.9 billion in revenue in Q2 alone.

Amazon has been a key backer, investing $8 billion in Anthropic convertible notes from Q3 2023 through Q4 2025. Amazon's stake is estimated in the mid-to-high teens percentage, worth $135 billion to $160 billion at the current valuation. Amazon has also committed to invest up to $20 billion more. By April, Amazon's position was carried at more than $74 billion on paper.

What Our Data Says: The AI Monetization Engine

Amazon's AI strategy is not just about Anthropic. The company's AWS cloud business is the backbone of AI infrastructure, and the Anthropic partnership deepens that moat. Our proprietary estimates model shows that AWS revenue growth is accelerating, driven by AI workloads. The $16.8 billion pre-tax gain from Anthropic in Q1 is more than 40% of Amazon's pre-tax income — a massive contribution from a single investment.

Beat-Rate Analysis: Amazon has consistently beaten consensus estimates on both revenue and EPS over the past four quarters. The average beat on EPS is 18%, and on revenue it's 3%. The Anthropic gains are a new, high-margin revenue stream that most analysts have not fully modeled.

Segment Breakdown: AWS remains the profit engine, contributing 62% of operating income on just 16% of revenue. Advertising is the fastest-growing segment at 24% YoY, and third-party seller services are growing at 12% YoY. The Anthropic investment is a wild card that could add billions to the bottom line annually.

Valuation & Technicals: Room to Run

Valuation: Amazon trades at 28x forward earnings, below its 5-year average of 35x. On an EV/EBITDA basis, it's at 18x, versus the tech peer average of 22x. The market is not fully pricing in the Anthropic windfall or the AI-driven acceleration in AWS.

Technical Scoring: Our technical model gives Amazon a score of 7.5/10. The stock is trading above its 50-day moving average but below its 200-day. RSI is at 55, indicating neutral momentum. Support is at $175, resistance at $195. A breakout above $195 could trigger a move to $210.

Peer Comparison: Amazon's forward P/E of 28x is cheaper than Microsoft's 32x and Alphabet's 30x, despite having a faster-growing cloud business and a massive hidden asset in Anthropic. This creates a compelling risk/reward.

The Bottom Line

Amazon's Anthropic investment is a masterstroke — it provides direct financial gains, deepens AWS's AI capabilities, and gives Amazon a stake in one of the most promising AI companies. With the IPO likely this fall, the market will soon have to revalue Amazon's stake. At 28x forward earnings, the stock is undervalued relative to peers and its own growth trajectory. We see 20% upside to our $210 price target over the next 12 months.
