Meta Platforms and Broadcom both surged this week amid major AI infrastructure announcements. Meta released an advanced reasoning model with expanded capabilities and opened its API to outside developers, with analysts projecting it will lead OpenAI and Anthropic in total AI compute by year-end. Broadcom gained after Apple committed more than $30 billion（約4.8兆円） to a multiyear custom silicon and wireless technology agreement, marking Apple's largest investment under its American Manufacturing Program.

Meta gained 9.1% this week after its AI division released Muse Spark 1.1, a multimodal reasoning model with a one-million-token context window, and launched a public preview of its Meta Model API for outside developers. Broadcom added 9.8% after Apple announced a multiyear agreement valued at more than $30 billion（約4.8兆円） to design and produce custom silicon and wireless components, including a $1.5 billion（約2400億円） capital expenditure investment to expand Broadcom's Fort Collins, Colorado facility. SK Hynix began U.S. trading on Friday, with shares around $171.35 apiece.
Why it matters
Research firm SemiAnalysis projects Meta will surpass both OpenAI and Anthropic in total AI compute by year-end through construction of five gigawatt-scale data center clusters, positioning its AI division to challenge Google's standing in frontier AI within six months. Apple's agreement is its largest commitment under its American Manufacturing Program and signals the company is locking up strategic semiconductor components at a time when broader availability and cost inflation remain a concern, according to Evercore ISI analyst Amit Daryanani.
What to watch
SK Hynix noted that more than 70% of chips produced at its China factories are exported, primarily to the United States, and the company said it is open to further U.S. investment. Bloom Energy declined 18% this week after short seller Hunterbrook published a report alleging the company's fuel cells rely on Chinese-sourced scandium, contradicting CEO statements since early 2025 that the company has no China supply chain dependency.
This week's market movements reflect growing competition in frontier AI compute and a strategic shift in semiconductor manufacturing. Meta's release of Muse Spark 1.1 and its public Meta Model API directly position the company against paid offerings from Anthropic and OpenAI, while SemiAnalysis's projection that Meta will lead in total AI compute by year-end suggests the company's infrastructure investments are beginning to yield competitive advantages. The scale of Meta's planned five gigawatt-scale data center clusters indicates the company is betting heavily on maintaining leadership in the frontier AI hierarchy.
Apple's $30 billion（約4.8兆円） agreement with Broadcom reflects broader supply-chain concerns among large tech manufacturers. Analyst commentary suggests the deal represents Apple's strategy to secure critical components amid ongoing component availability and cost inflation pressures. The emphasis on U.S. manufacturing through the American Manufacturing Program signals both companies' alignment with domestic production priorities, while SK Hynix's U.S. market debut and notes about China export dependency underscore the geopolitical and supply-chain dimensions of semiconductor strategy across the industry.
