AI Bets Deliver $20B Windfall for Tech Giants

According to Bloomberg Business, Alphabet Inc. and Amazon.com Inc. reported better-than-expected third-quarter profits significantly boosted by their investments in Anthropic PBC, the company behind the Claude chatbot. Alphabet disclosed profit that included “net gains on equity securities of $10.7 billion,” partly from a private company that sources identified as Anthropic. Meanwhile, Amazon’s third-quarter profit surged 38%, helped by a $9.5 billion pretax gain from its Anthropic investment, which was reflected in the company’s nonoperating income according to its Thursday earnings report. These massive paper gains demonstrate how AI investments are becoming major contributors to tech giant earnings.

The Accounting Behind the AI Windfall

What’s crucial to understand about these massive gains is that they represent paper profits rather than cash returns. Under accounting rules, companies must mark their equity investments to market value each quarter, even when those investments remain private. This creates volatility that can significantly impact reported earnings without affecting operational performance. For Alphabet and Amazon, these gains reflect the soaring valuation of Anthropic in a competitive AI market, but they don’t translate to distributable cash. Investors need to separate these accounting gains from the core business performance that actually drives long-term value creation.

Strategic Positioning in the AI Arms Race

The timing of these valuation spikes reveals the intense strategic positioning happening behind the scenes. Both companies are using their Anthropic stakes to secure competitive advantages in the AI infrastructure war. For Alphabet, this investment complements their internal Google AI efforts while providing diversification beyond their core models. Amazon’s position gives them leverage in the cloud computing battle, as Anthropic runs its models on AWS infrastructure. These aren’t passive financial investments—they’re strategic chess moves in a high-stakes game where control over foundational AI models could determine the next decade of tech dominance.

The Volatility Risk Investors Aren’t Discussing

While these paper gains look impressive, they introduce significant volatility risk that could work in reverse during market downturns. The same accounting rules that require marking investments up during valuation spikes also require marking them down during corrections. If the AI investment bubble shows any signs of deflating, these same companies could face massive paper losses that negatively impact their earnings reports. This creates a potential whipsaw effect where quarterly results become increasingly dependent on external investment valuations rather than operational excellence. The concentration risk is also notable—both tech giants are heavily exposed to the same private company, creating correlated risk across the tech sector.

Broader Market Implications

This development signals a broader shift in how major tech companies are approaching innovation and competition. Rather than solely relying on internal R&D, they’re making strategic bets across the AI ecosystem through equity investments. This creates a new dynamic where public company earnings become tied to private market valuations in unprecedented ways. The stock market response to these earnings reports suggests investors are rewarding this strategy, but it raises questions about transparency and valuation methodologies for private companies that can materially impact public market performance.

What Comes Next in the AI Investment Cycle

Looking forward, we should expect more of these strategic investments as the AI landscape continues to consolidate around major platforms. The success of the chatbot ecosystem has demonstrated that there’s room for multiple successful models, driving increased competition for stakes in promising AI startups. However, regulatory scrutiny will likely intensify as these investments become larger and more strategically important. The current environment resembles the early days of cloud computing or mobile platforms, where strategic positioning through acquisitions and investments ultimately determined which companies captured the most value from technological shifts.
