Introduction: The Hidden Value in Google's Silicon
Investors worldwide are turning their attention to a critical component of Google's infrastructure: Alphabet TPU chips. These proprietary semiconductors have been identified as the primary driver behind the stock's 31% rally in the fourth quarter, marking one of the best performances in the S&P 500. While long seen as an internal strength for accelerating cloud computing, optimism is growing that Alphabet could start selling these chips to third parties, creating a massive new revenue stream.
Context: What Are TPUs and Why Do They Matter?
Tensor Processing Units (TPUs) are application-specific integrated circuit (ASIC) chips, custom-designed to accelerate machine learning workloads. Unlike general-purpose GPUs, TPUs are optimized for specific tasks.
This specialization makes them less flexible than Nvidia semiconductors but significantly cheaper and more efficient for their intended uses. At a time when investors are beginning to question the efficiency of AI spending, the cost-effective alternative offered by Google becomes extremely attractive.
The Market Opportunity: A $900 Billion Estimate
The hypothesis igniting markets is that Alphabet's chip business could reach a valuation of nearly one trillion dollars. Analysts suggest that if Alphabet decides to aggressively market its TPUs, it could capture a significant share of the AI market.
"If companies want to diversify away from Nvidia, TPUs are a good way to do it. Chip business could ultimately be worth more than Google Cloud."

According to Luria's estimates, should Alphabet get serious about selling, they could capture 20% of the AI market over a few years, making the hardware division a roughly $900 billion business.
Growth Projections
Morgan Stanley has also revised its expectations upward, forecasting significant numbers for the coming years:
- 2027: About 5 million TPUs bought (up roughly 67% from previous estimates).
- 2028: 7 million units (120% above prior estimates).
Financially, every 500,000 TPU chips sold to third-party data centers could add about $13 billion to Alphabet's 2027 revenue. Given that projected revenue for that year is around $447 billion, this would represent a sales boost of almost 3%.
Skepticism and Reality: Valuation Risks
Despite the excitement, the $900 billion business estimate is considered by some to be "wildly optimistic." Significant barriers cannot be ignored:
- Nvidia's Dominance: Nvidia currently holds an 80-95% market share, supported by a proven software ecosystem.
- Unconfirmed Strategy: Alphabet has not yet fully committed to an aggressive strategy of selling TPUs externally.
- Relative Impact: Even with massive sales, the percentage increase in total revenue (about 3% per half-million units) is not necessarily transformative for a company of Alphabet's size.
Conclusion
Alphabet TPU chips offer the company an undeniable advantage through vertical integration: Gemini is optimized for them, and Google Cloud sells access to them. However, monetizing this advantage through direct chip sales is different from internal use. The current valuation reflects investor anticipation of a strategy that Google has not yet fully embraced.
FAQ
What exactly are Alphabet TPU chips?
They are application-specific integrated circuits (ASICs) custom-designed by Google to accelerate machine learning workloads, offering an efficient alternative to general chips.
Why are investors focused on Alphabet TPU chips?
Investors believe selling these chips to third parties could create a $900 billion business, diversifying revenue beyond ads and cloud services.
Can Alphabet TPU chips replace Nvidia?
They serve as a cost-effective alternative for specific workloads (diversification), but they currently lack the general flexibility and established ecosystem of Nvidia.
What are the sales projections for TPUs?
Morgan Stanley expects about 5 million TPUs to be bought in 2027. Selling 500,000 units to third parties could add $13 billion in revenue.
