Broadcom is reportedly assembling up to $100 billion in debt to build AI chips for Anthropic — in the same week bond markets hit 19-year-high yields

The largest semiconductor financing ever contemplated surfaced on Thursday not as a press release but as a Bloomberg headline: Broadcom is in talks with a group of lenders to raise more than $60 billion in debt to finance AI chips and computing infrastructure for Anthropic and potentially other AI companies. The full structure under discussion, per the report, runs larger still — a senior secured tranche of roughly $60 to $70 billion, partially guaranteed by Broadcom, above a junior tranche of about $30 billion. Total: as much as $100 billion. Blackstone and Apollo Global Management are in talks to participate. Broadcom, Anthropic and both firms declined to comment.

For scale: when Broadcom bought VMware in 2023 — at $69 billion, one of the largest tech acquisitions in history — it needed a $28.4 billion bank package. The financing now being discussed is roughly three times that, for chips that will be leased, not owned, by the company whose demand justifies them.

The lender roster tells its own story. Blackstone and Apollo are not banks; they are the two largest alternative-asset managers on earth, sitting on insurance balance sheets and private-credit funds that need long-duration assets yielding more than Treasuries. AI infrastructure — twenty-year assets, investment-grade wrappers, a Broadcom guarantee — is precisely the paper they were built to absorb. The banks that once syndicated deals like VMware's are increasingly spectators.

The machine being financed

The talks build on a structure that already exists. In June, Broadcom, Apollo and Blackstone formed a partnership called AI XPV, with an initial commitment of about $35 billion: the investment firms finance purchases of Broadcom's custom AI accelerators, the chips are leased to Anthropic, and Broadcom backstops most of the debt, per Bloomberg and Reuters. The initial tranche targeted about one gigawatt of computing capacity. The partnership's stated ambition is more than 20 gigawatts by 2028 — the output of roughly twenty nuclear plants, expressed as silicon.

Reporting so far suggests the new money would be raised incrementally rather than in one closing, which matters: each tranche prices against wherever credit markets are at the time. The first $35 billion committed in June against April's calmer yield curve. The next slug would price against a 30-year Treasury above 5.3% — the difference, across $100 billion, is measured in billions of dollars a year of interest.

The demand curve it serves is steep. Chief executive Hock Tan told investors that Anthropic sits at about one gigawatt of TPU-class compute this year, with 2027 demand "expected to surge in excess of 3 gigawatts." Broadcom's AI semiconductor revenue hit $10.8 billion last quarter, up 143% from a year earlier; Tan has guided the full fiscal year to about $56 billion and reiterated that fiscal 2027 AI revenue will exceed $100 billion — with reports, unconfirmed by the company, putting Anthropic at more than 40% of that figure.

Our strategic vision is to bring together Broadcom's leading technology and investor partners with the strongest balance sheets to deliver at scale sufficient compute capacity at the lowest cost and power for the leading AI frontier labs, including Anthropic and OpenAI.

That is Tan's framing, from the company's earnings call. Translated from the language of capital formation: the AI labs cannot pay cash for the chips they need, the hyperscalers financing them cannot absorb everything on their own balance sheets, and so the chipmaker itself has stepped into the arrangement — designing the silicon, guaranteeing the debt that buys it, and collecting the revenue the debt finances.

The week the lenders got nervous

The timing is the tension. The report landed in a week when the 30-year Treasury yield touched 5.34%, its highest since 2007, and global long bonds sold off from Tokyo to London. Capital-intensive AI names bore the brunt — Bloomberg's Monday headline was "Chip Stocks Get Hit as Global Bond Anxiety Builds." Spreads on hyperscaler bonds have widened to their fattest since April, and credit-default swaps on Alphabet, Amazon, Meta, Nvidia, Oracle and Broadcom itself have moved to multi-month or record levels.

Broadcom has already felt the sensitivity directly. On August 14, a Bank of America note estimating that the chip-financing vehicle could balloon to roughly $370 billion of senior debt by mid-2029 at full 20-gigawatt scale knocked the stock down 6% in a session — days after its market value had crossed $2 trillion. Thursday's report, by contrast, nudged shares up modestly. The equity market, at least, has decided that the debt is someone else's problem. The credit market is less sure whose problem it is: the special-purpose structure keeps the borrowing off Broadcom's balance sheet, but the guarantee that makes the senior tranche investment-grade leads straight back to it.

The context is an AI debt boom without precedent. Meta, Amazon, Alphabet, Nvidia, Oracle and SpaceX have combined 2026 issuance topping $200 billion, per Bloomberg — including a $12.5 billion Meta data-center bond that had to pay 7.5% to clear. Oracle's borrowings have passed $108 billion. Meta's Hyperion venture with Blue Owl, at $27 billion of debt, was the largest private-capital deal ever done when it closed in October. A Broadcom package at $100 billion would dwarf all of them, in a market that JPMorgan's investment-grade chief John Servidea says is already fighting "the lack of secondary market performance." One fixed-income manager, Canada Life's Kshitij Sinha, put the buyer's mood more plainly: "I am not in a hurry to add."

Circularity, with collateral

The skeptics' word for all this is circular: the chipmaker guarantees the debt that finances the purchase of its own chips, booking the revenue while retaining much of the risk. If Anthropic's growth delivers — and its trajectory so far has outrun every forecast — the structure is simply project finance for the fastest-growing industrial buildout in history, and Broadcom will have used other people's money to lock in the second-biggest customer relationship in semiconductors. If demand disappoints, the lease payments stop, the special-purpose vehicle's collateral is warehouses of rapidly depreciating custom silicon, and the guarantee comes home.

Nothing announced Thursday is final — the terms could change, the rollout would likely be phased, and no party has confirmed the numbers. But the direction is unmistakable, and it is the same direction as Nvidia's $105 billion OpenAI guarantee and Google's warrant deal with Marvell this same week. The AI boom's first act was funded by cash flow — the richest companies on earth writing checks. The second act is being funded by structure: SPVs, guarantees, leases and warrants, engineered to keep nine-figure ambitions moving faster than any balance sheet would allow. Bond yields at 19-year highs are the market's way of asking how long that can continue. A $100 billion syndication would be Broadcom's way of answering: at least one more round.

The number to watch next is not in the term sheet. Broadcom reports earnings in early September, and the line analysts will read first is the fiscal 2027 AI guidance — the $100 billion-plus figure that justifies every gigawatt of the buildout. As long as that number keeps rising, the debt finds buyers at a price. The first quarter it wobbles, $370 billion of theoretical senior paper becomes the most closely re-read footnote on Wall Street.
