Broadcom stock fell 6% on Friday after Bank of America analyst Tom Curcuruto estimated the chipmaker’s off-balance-sheet AI financing vehicle could accumulate $370 billion in senior debt by mid-2029, raising fresh concerns about how heavily the semiconductor sector is leveraging itself to fund the AI infrastructure boom.
The $370 billion figure assumes the financing platform scales to its full 20-gigawatt design, with roughly $150 billion of new debt issuance projected for 2027 alone. Curcuruto’s note highlighted that while the debt does not sit on Broadcom’s balance sheet—the vehicle raises capital independently and leases custom AI accelerators to customers—Broadcom has agreed to backstop lease payments for five years with maximum exposure of up to $29 billion on the initial transaction.
Broadcom’s underlying business remains robust. The company reported fiscal Q2 2026 revenue of $22.19 billion, up 47.9% year-over-year, with AI chip revenue surging 143%. Management has guided to $16 billion of AI semiconductor revenue for the current quarter, and Polymarket traders assign a 94% probability that Broadcom will exceed $15 billion in AI revenue this quarter.
The stock decline reflects investor unease over the financing structure itself, not underlying demand. Broadcom launched the AI XPV Platform in June in partnership with Apollo and Blackstone, securing a $35 billion financing package that supports more than 1 gigawatt of compute for Anthropic and is sized to support more than 20 gigawatts for frontier AI labs through 2028. Blackstone has already begun sounding out investors for a second transaction exceeding $30 billion.
The BofA estimate drew fresh scrutiny to how the AI industry is funding its rapid expansion. Nvidia announced a structurally similar $500 billion financing framework in August, partnering with Goldman Sachs, Blackstone, Apollo, KKR, BlackRock, and Brookfield to help customers access capital for AI infrastructure. However, Nvidia’s announcement avoided attaching a specific debt figure to the plan, and no deals were signed at the time of the announcement—a disclosure difference that may have shielded the graphics processor maker from the same sell-off Broadcom experienced.
Semiconductor stocks have faced recurring waves of AI spending concerns since June 2026, as investors periodically question whether the massive capital commitments from hyperscalers will justify the lofty valuations and debt loads being taken on to fund them. The iShares Semiconductor ETF fell only 0.7% on Friday, while Intel dropped 2%, confirming that Broadcom’s 6% decline was a single-name repricing rather than a sector-wide shift. Baird analyst Tristan Gerra doubled his AMD price target to a Street-high $1,250 the same day, underscoring the divergent verdicts the market is reaching on individual balance sheets and financing strategies within the AI chip space.
