Broadcom's Off-Balance-Sheet Bill Comes Due Just as AI Orders Surge

Broadcom's custom AI silicon revenue jumped 221% to $16.7B, but roughly $29B in off-balance-sheet guarantees keep investors cautious.

Broadcom finds itself caught in a tug-of-war between two narratives, and the market is still working out which one deserves the upper hand. On one side sits a custom-silicon franchise growing at a pace few semiconductor peers can match. On the other sits a web of financial guarantees that never appear on the company's balance sheet but could bite if the AI buildout loses steam.

The stock closed Friday at EUR 311.00, up 2.6% on the session, yet still roughly 28% below its 52-week high. That gap tells the story of a market that has repriced the risk without abandoning the thesis.

The $29 Billion Question

At the center of investor unease is a Financial Times investigation revealing that major technology firms extended guarantees worth up to $300 billion last year to underwrite data-center construction and specialty processor procurement. Broadcom's share of that total comes to roughly $29 billion, tied largely to financing chips for a purpose-built vehicle set up by AI startup Anthropic in partnership with Google. Those structures backstop the delivery of processors capable of one gigawatt of output.

The mechanics matter here. These residual-value guarantees generally don't qualify as conventional liabilities under accounting rules, surfacing instead in the footnotes to financial statements. If utilization or monetization of the financed infrastructure stumbles, those contingent obligations could land directly on the companies involved. For institutional investors, that opacity is precisely the problem — a risk premium for exposures visible only in the fine print is a reasonable demand, not an overreaction.

Custom Silicon Fires on All Cylinders

Strip away the balance-sheet debate, though, and Broadcom's operating engine looks formidable. Third-quarter revenue climbed 86% to $29.6 billion. The custom AI processor line did the heavy lifting, with sales exploding 221% to $16.7 billion — now accounting for more than half of total business. Cloud providers increasingly favor bespoke accelerators over off-the-shelf alternatives, and Broadcom is the primary beneficiary.

The order book reinforces that position. A reported backlog of $179.2 billion gives the company unusually deep visibility into coming quarters.

CEO Hock Tan has responded by ratcheting guidance higher. Management now targets $58 billion in AI revenue for fiscal 2026, with Tan floating roughly $115 billion for 2027 and about $230 billion for 2028. Those figures rest on firm supply agreements rather than speculative demand, which lends them more credibility than the headline numbers alone suggest.

Concentration Cuts Both Ways

The same guarantees that unsettle investors also highlight how tightly Broadcom's fortunes are bound to a handful of dominant players. An estimated 71% of planned XPU accelerator shipments in fiscal 2027 and 2028 depend on orders from OpenAI and Anthropic. Tan has stressed that demand for computing infrastructure remains extremely robust, but reliance on a few large customers carries structural risk regardless of how strong the near-term outlook appears.

Broadcom is hedging where it can. Its partnership with Meta Platforms to manufacture the company's in-house MTIA accelerators runs through 2029, diversifying the customer base at the margin.

Wall Street Still Sees Room to Run

Analyst sentiment has not soured. JPMorgan, in a sector study, notes that Broadcom and Marvell dominate the custom AI ASIC market, assigning Broadcom a share of 80% to 85%. Morgan Stanley carries a $505 price target, while Piper Sandler rates the stock Overweight with a $460 target. After the pullback, the expected price-to-earnings ratio has compressed to around 18, giving the consensus plenty of room to forecast a meaningful recovery.

The company raised its AI chip revenue outlook roughly two weeks ago on the back of that 221% segment growth, a move that briefly gave the shares a breather before the broader consolidation resumed.

Where the Two Stories Meet

The correction is best read as a recalibration rather than a rupture. Off-balance-sheet guarantees warrant scrutiny and argue for vigilance, but Broadcom's operating earnings power appears capable of carrying those obligations. As long as demand for custom computing power holds firm, the fundamental momentum outweighs the accounting question marks — and the current consolidation may be laying the groundwork for the next leg higher.
