Broadcom is in talks with a group of banks about raising more than $60 billion in new debt, with the total potentially reaching $100 billion, to fund an expansion of its custom chip business for artificial intelligence, according to people familiar with the matter. Bloomberg first reported the financing plans on Thursday.
The borrowing would be among the largest debt raises in the semiconductor industry. Broadcom has been building a business designing bespoke processors for AI companies, chips tailored to the specific models and workloads of each customer rather than sold as generic parts. The company is the main supplier of custom AI chips to both Anthropic and OpenAI, and it has been competing with Nvidia, which dominates the market for AI processors with its own line of accelerators.
The scale of the financing reflects the scale of the opportunity Broadcom sees. Custom chips for AI require enormous investment: design teams, test facilities, and above all manufacturing capacity, which must be reserved with foundries years in advance. Broadcom has been expanding its relationships with chip manufacturers and needs capital to lock in the capacity that its customers’ growth will require. The company has told investors that its AI chip orders could grow to tens of billions of dollars annually, and the debt raise is designed to fund that expansion without diluting shareholders.
The timing is pointed. Broadcom’s announcement follows a period in which its stock came under pressure from a partnership between Google and Marvell Technology, which have been developing their own custom AI chips and were reported to be taking business that Broadcom had hoped to keep. The Google-Marvell news hit Broadcom’s shares, and the company’s response has been to signal that it is doubling down on the business rather than retreating from it. Taking on debt to expand capacity is the most direct answer the company could give to doubts about its position.
The company’s custom chip business has become central to its identity. Broadcom has long been a diversified supplier of semiconductors, with businesses in networking, storage, and software, but the AI chip line has become its fastest-growing division and the main driver of its valuation. Management has said it expects AI-related revenue to account for a growing share of the company’s sales, and the debt raise is a bet that the trend continues for years.
Banks are expected to compete for the mandate, which would generate substantial fees. The structure of the financing has not been finalized, and the amount could change depending on market conditions, according to people familiar with the talks. Broadcom has a strong credit rating and a history of managing large balance sheets, which gives lenders confidence, but a $100 billion raise would still be a notable test of the debt markets’ appetite for the AI trade.
The move also reflects a strategic calculation about competition with Nvidia. Nvidia’s advantage has been its software ecosystem and the sheer scale of its production, and Broadcom cannot match that by being cautious. By borrowing to secure manufacturing capacity, Broadcom is betting that the demand for custom chips will grow fast enough to justify the interest costs. The company’s customers, including the AI labs that train the largest models, have been clear that they want alternatives to Nvidia’s standard parts, and Broadcom is positioning itself to supply them.
There are risks. The AI chip market is young, and the orders that Broadcom is counting on could be delayed or canceled if the technology changes or if customers build their own designs in-house. The company’s biggest customers are also its biggest potential competitors, and the debt load would leave Broadcom less flexible if the market turns. Analysts who follow the company say the financing is a judgment call: the upside justifies the added debt, but the downside is that the company is borrowing against a future that has not yet arrived.
The financing round is being watched across the industry for what it says about the health of the AI trade. If banks are willing to lend Broadcom $100 billion, it will be taken as a vote of confidence in the custom chip business and in AI infrastructure spending more broadly. If the raise comes in smaller, or at worse terms than expected, it will be read as caution. The company’s stock will move on the details.
Broadcom’s chief executive, Hock Tan, has built a reputation for bold financial engineering, using acquisitions and debt to reshape the company repeatedly over the past decade. The AI chip expansion fits that pattern: a large bet, financed aggressively, aimed at a market the company believes will be enormous. Tan has said he expects AI to be the company’s defining opportunity, and the size of the borrowing shows he intends to pursue it at full scale.
For the broader market, the question is what the money will buy. Broadcom is not buying another company; it is buying capacity and time, reserving manufacturing space and talent before its competitors can secure them. If the bet pays off, Broadcom will have the largest custom chip business in the world. If it does not, the company will be left with debt and capacity it cannot fill. Either outcome will say something important about whether the AI boom is as durable as its believers claim.
