Broadcom's $100B Chip Raise Turns AI Capacity Into a Credit Question

Broadcom is reportedly negotiating $60 billion to $100 billion in debt to finance AI chip production for Anthropic and its other customers, with private-credit firms potentially joining ^[1][2]. That reframes the question operators should be asking about accelerator supply: not whether the silicon can be designed, but whether the credit markets that pay for it stay open.

The structure is the tell. According to reports summarised by Cryptopolitan, the package splits into a senior secured portion of roughly $60 billion to $70 billion, part of which Broadcom is expected to guarantee, and a junior tranche of about $30 billion ^[3][4]. A special-purpose vehicle would issue the debt, keeping it off Broadcom's own balance sheet, and Blackstone and Apollo Global Management are in talks to participate ^[5][6]. Junior paper at that size is roughly 30 percent of a $100 billion total ^[18], which is where the risk actually sits: senior lenders with a guarantee behind them are buying a different instrument than whoever ends up holding the junior piece.

This is not an isolated deal. Goldman Sachs Research expects AI-related debt issuance to approach $500 billion by 2026, and its credit strategist Amanda Lynam said it is "hard to overstate the importance of this theme in the credit markets, both in terms of its overall scale" ^[7][8]. One raise at the top of Broadcom's range would be about a fifth of that estimated annual total ^[19]. Nvidia, per the same report, arranged in August with Apollo, Blackstone, BlackRock, Brookfield, Goldman Sachs and KKR to obtain over $500 billion in third-party financing ^[10]. The competitive variable is shifting from process technology to cost of capital.

The precedent is recent. In June, Broadcom, Apollo and Blackstone launched a platform with an initial $35 billion transaction to expand Anthropic's computing capacity by more than one gigawatt, with a stated goal of bringing 20-plus gigawatts to frontier labs including Anthropic and OpenAI by 2028 ^[11][12]. Bank of America's Tom Curcuruto has said the facility could grow to $370 billion of senior debt by mid-2029 to finance those 20 gigawatts ^[13]. For physical scale: Cryptopolitan reported in April that a one-gigawatt data centre draws about as much power as a million US homes, which puts the 2028 target near 20 million homes' worth of demand ^[14][20].

Lenders are not underwriting a slide deck. Broadcom's AI semiconductor revenue was $10.8 billion in the fiscal second quarter the source dates to May 3, up 143 percent year over year, against total quarterly revenue of $22.2 billion, which makes AI roughly 49 percent of the company ^[15][17][21]. CEO Hock Tan told investors he expects the AI figure to exceed $16 billion in the third quarter, growth of more than 200 percent ^[16]. Broadcom already designs custom silicon for Alphabet and Meta and holds supply agreements with Anthropic and OpenAI ^[9].

What to watch: the clearing spread on the junior $30 billion, since that price is the market's read on demand risk in 2029, not 2026 ^[3]. Watch whether the SPV structure holds when the next tranche prices, and whether Broadcom's guarantee obligations widen ^[4][5]. And watch the Goldman issuance run-rate against its own $500 billion figure ^[7]. If credit tightens, the constraint on frontier compute becomes a financing calendar rather than a fab schedule.
