Google is offering its TPUs externally for the first time as a strategic move to gain market share while it has a temporary hardware advantage over Nvidia. This classic tactic aims to build a crucial install base that can be upgraded later, even after its competitive performance edge inevitably narrows.

Meta is deprioritizing its custom silicon program, opting for large orders of AMD's chips. This reflects a broader trend among hyperscalers: the urgent need for massive, immediate compute power is outweighing the long-term strategic goal of self-sufficiency and avoiding the "Nvidia tax."

Tech giants often initiate custom chip projects not with the primary goal of mass deployment, but to create negotiating power against incumbents like NVIDIA. The threat of a viable alternative is enough to secure better pricing and allocation, making the R&D cost a strategic investment.

Meta's massive, multi-billion dollar deal for millions of Nvidia GPUs signifies a strategic pivot. After pursuing custom silicon and AMD partnerships to avoid the 'Nvidia tax,' Meta is now committing to Nvidia for the foreseeable future. This move aims to secure a dominant supply of leading AI chips at world-leading scale, prioritizing performance and availability over cost diversification.

For a hyperscaler, the main benefit of designing a custom AI chip isn't necessarily superior performance, but gaining control. It allows them to escape the supply allocations dictated by NVIDIA and chart their own course, even if their chip is slightly less performant or more expensive to deploy.

Even if Google's TPU doesn't win significant market share, its existence as a viable alternative gives large customers like OpenAI critical leverage. The mere threat of switching to TPUs forces NVIDIA to offer more favorable terms, such as discounts or strategic equity investments, effectively capping its pricing power.

Major AI labs aren't just evaluating Google's TPUs for technical merit; they are using the mere threat of adopting a viable alternative to extract significant concessions from Nvidia. This strategic leverage forces Nvidia to offer better pricing, priority access, or other favorable terms to maintain its market dominance.

The huge CapEx required for GPUs is fundamentally changing the business model of tech hyperscalers like Google and Meta. For the first time, they are becoming capital-intensive businesses, with spending that can outstrip operating cash flow. This shifts their financial profile from high-margin software to one more closely resembling industrial manufacturing.

Major chip manufacturers are shifting from selling generic GPUs to offering custom-tuned hardware using modular "chiplet" technology. This allows them to tailor chips for specific workloads, like Meta's, directly competing with startups whose primary value proposition is hyper-specialized, custom silicon.
