Broadcom sinks 6% on $370B AI financing debt flag; AMD climbs 4%

The market's divergent reaction to Broadcom and AMD reveals a shift in how investors perceive AI infrastructure financing risk. Broadcom's stock fell despite robust underlying demand—fiscal Q2 2026 revenue of $22.19 billion was up 47.9% year over year, with AI chip revenue surging 143%—because Bank of America attached a specific $370 billion debt projection to Broadcom's financing vehicle. That figure was not previously disclosed in dollar terms; Broadcom had only noted in its 10-Q that an investor partner assumed purchase and lease agreements while Broadcom backstopped lease payments for five years with maximum exposure of up to $29 billion on the initial transaction.

Broadcom's vehicle launched in June with a $35 billion financing led by Apollo and Blackstone to fund more than 1 gigawatt of compute for Anthropic, with the platform sized to scale to 20 gigawatts through 2028. The body suggests Blackstone has already approached investors for another transaction exceeding $30 billion. This structure parallels NVIDIA's recently announced $500 billion framework with the same financial sponsors (Goldman Sachs, Blackstone, Apollo) plus KKR, BlackRock, and Brookfield—yet NVIDIA's announcement was treated as a positive signal of scale, while Broadcom's quantified financing trajectory triggered selling. The broader semiconductor sector was largely unmoved (the iShares Semiconductor ETF down only 0.7%, Intel down 2%), confirming this was a repricing of individual balance sheets rather than a sector-wide concern.
