Will Direct TPU Sales Re-Rate Google Stock?

Quietly, a merchant silicon business is emerging inside the world's largest advertising platform. The company has now started delivering its custom TPU systems directly into customer data centers. This marks a fundamental expansion of the business model, moving from selling services to selling the core hardware that powers the AI transition.

This new hardware stream feeds a Google Cloud segment that is already compounding at a stunning rate. With Cloud revenue up 82% and a backlog now at $514 billion, expanding customer commitments provide substantial runway for top-line growth.

That's the story. The cleanest way to interrogate it is to break the 3-year stock move in Alphabet (GOOGL) into the three things that can drive it: revenue compounding, net margin trajectory, and the multiple itself. Then look at which one is doing the heavy lifting under conservative assumptions.

Today's price is paying for some combination of these three. Under our conservative calibration:

Revenue compounding at 17.0% annually. Top line moves from $445.9 billion to $714.9 billion. Standalone contribution to the price move: 60% .

Net margin eases from 55% to 48%. Standalone contribution: -13% .

P/E multiple is held flat at today's 16.8x by assumption, so it contributes nothing to the target by construction. Standalone contribution: 0.0% .

Multiplied through, the three combine to roughly 40% of upside over three years. Before we stress each one, here is the picture they are operating on top of:

What Happens To Upside If The Levers Change?

The base case lands at 40% . Soften revenue compounding by 200 basis points, so the top line grows at 15.0% instead of 17.0%, and the upside slides toward 33% . Let net margin give back to the 3-year average of 31%, below the 48% the base case holds, and it lands closer to -8.5% .

Testing multiple sensitivity highlights key downside risks: if the valuation multiple compresses from 16.8x to 14.5x, projected 3-year upside shrinks from 40% to roughly 21% . Conversely, stretching the horizon from 3 years to 5 lifts the upside to 91% , with compounding math working in the patient investor's favor

The catalyst is the coming acceleration in this new hardware business, which is not yet in the run-rate. Management stated that the vast majority of revenues from existing TPU system sales agreements will be realized in 2027. This provides a discrete, new revenue layer on top of the existing growth.
