Broadcom’s deal to enable Anthropic’s purchase of its artificial intelligence hardware and infrastructure — underwritten by a coalition of banks and private-equity capital — powered gains across chip stocks and sent the Nasdaq Composite sharply higher on Oct. 27, 2026.
What happened
Shares of Broadcom rose about 4% after companies including Bank of America, Citigroup and Morgan Stanley, together with private-equity firm Blackstone, announced $63 billion in financing that will let Anthropic acquire Broadcom’s AI technology, according to coverage of the agreement. The funding structure uses a special-purpose vehicle that will buy the hardware and lease it to Anthropic, the reports said.
- Nasdaq Composite closed at 26,477.81, up 1.18%.
- S&P 500 ended at 7,722.60, up 0.6%.
- Dow Jones Industrial Average finished at 52,377.57, up 0.03%.
- Broadcom shares jumped about 4% on the financing news.
Why it mattered
Analysts and traders said the financing eased investor concerns about how Anthropic would pay for a major buildout of AI infrastructure, and it restored momentum to a group of stocks that had been under pressure amid questions about corporate AI spending. The arrangement — which does not involve an outright cash purchase by Anthropic but instead uses bank and institutional financing to lease Broadcom’s gear — was described by at least one analyst as providing residual-value support rather than an upfront cash investment.
“The market has these kind of periodic interludes where it gets concerned about AI spending, and then we tend to go back and tech leads us higher,” said Jed Ellerbroek, Argent Capital Management portfolio manager.
The ripple effect helped lift other semiconductor and memory names. Advanced Micro Devices gained more than 5% and Intel and Micron also advanced, following Broadcom’s move. Industry-focused ETFs tracking semiconductors and memory stocks climbed alongside individual chipmakers.
Broader market context
Investors were also focused on the Federal Reserve’s two-day meeting that began Oct. 27, with a policy announcement due Oct. 28. Markets broadly expect the Fed to pause on further rate hikes at this meeting, though traders said any signal about the central bank’s outlook for inflation and future tightening could move Treasuries and equities.
The financing news and the Fed’s meeting combined to concentrate market attention on technology and AI-related capital spending, a dynamic that can affect corporate borrowing costs, data-center investment plans and the capital markets that underwrite large infrastructure deals.
