Alphabet and Broadcom both posted strong earnings tied to AI demand, but they occupy different positions in the value chain. Alphabet is a hyperscaler (large cloud provider) building its own custom chips to feed its $460 billion（約74兆円） cloud services backlog, while Broadcom supplies chips as a merchant vendor to multiple customers. This structural difference means Alphabet captures more of the AI hardware margin and controls its own stack, whereas Broadcom's growth depends on selling to external buyers.

Alphabet and Broadcom both reported strong AI quarters, but Alphabet is building its own custom chips (TPUs) to power its cloud services, while Broadcom supplies chips to other companies. Alphabet also has a $460 billion（約74兆円） cloud backlog to work through.
Why it matters
Alphabet's position as both a chip maker and hyperscaler (large cloud provider) gives it more control over its AI infrastructure and revenue streams, whereas Broadcom depends on merchant silicon sales to multiple customers. This structural difference means Alphabet captures more of the AI hardware value chain.
What to watch
The widening gap between Alphabet's vertically integrated model and Broadcom's supplier role suggests investors may see different long-term returns as the AI cycle matures.
Alphabet and Broadcom have both benefited from the surge in AI computing demand, but their business models place them at different points in the value chain. Alphabet operates as both a custom chip designer and a hyperscaler—it builds TPUs internally and deploys them across its own cloud platform to serve customers. This vertical integration means Alphabet captures chip design margin, manufacturing margin, and cloud service margin on the same workload. Broadcom, by contrast, operates as a merchant supplier, selling silicon to multiple hyperscalers and other buyers. While Broadcom benefits from the absolute growth in AI chip demand, it competes on price and feature parity with other vendors and depends on customers' capital spending cycles. The $460 billion（約74兆円） cloud backlog cited for Alphabet underscores the scale of infrastructure the company is building to support its own AI services, which creates a structural moat: Alphabet's custom chips are optimized for its workloads and unavailable to competitors. This positioning difference suggests the two companies' earnings trajectories and valuations may diverge as the AI supercycle matures and margin pressure shifts the competitive dynamics.
