Broadcom-Google AI Chip Pact Expands; Marvell Rally Follows

Google broadened its collaboration with Marvell, expanding AI chip work and issuing a warrant that could translate into about 12.2 billion dollars upfront and up to 120 billion dollars in cumulative Marvell revenue through 2033, signaling a diversification of Google’s silicon suppliers without abandoning Broadcom. Broadcom, long a primary partner for Google’s custom AI chips, saw its shares fall about 5% as investors weighed the potential shift toward Marvell and the broader implications for Broadcom’s business. The market reaction on Aug. 19 was mixed across peers, with Marvell rising while rivals like Nvidia held steady and AMD declined, reflecting sector-adjusted positioning around Google’s design choices. Broadcom’s exposure to such design wins recalls a 2023 episode when Apple contemplated in-house alternatives, though Apple’s shift did not fully displace Broadcom at that time, suggesting this is more about portfolio diversification than immediate replacement. Industry commentary also compared Broadcom to Onto Innovation on multiple metrics, noting Broadcom’s higher upside consensus despite Onto Innovation’s higher beta, and highlighting differences in institutional ownership. In investment notes, BESTINVER cited Broadcom as a data-center leadership name with strong growth prospects, signaling continued demand for Broadcom’s role in infrastructure.
