A Wall Street syndicate assembled around Broadcom is putting together $60 billion in fresh financing to fund AI chips for Anthropic PBC and other companies, Bloomberg News reports. The package, which has been taking shape for weeks, ranks among the largest debt deals tied to the AI infrastructure buildout.

Banks involved in the transaction are preparing to send out syndication letters for a $42 billion Class A senior-secured tranche, according to the report. Blackstone is leading an $18 billion tranche of Class B junior debt, committing $9 billion from various funds and planning to syndicate the remainder to other investors.

The structure splits the $60 billion total into two tiers: a senior-secured slice backed by collateral and a subordinate tranche that carries higher risk and, typically, higher yield. Blackstone's decision to anchor half of the junior tranche with its own capital signals confidence from one of the largest credit investors in private markets.

Professionals across Wall Street and Silicon Valley are watching the financing closely. The deal has become a test of whether investors remain willing to fund AI's physical expansion at a time when data-center construction faces a public backlash over power consumption, land use, and local opposition.

The commercial logic behind the package is straightforward. Broadcom wants to sell more chips and other data-center equipment, challenging Nvidia's dominant position in AI accelerators. Anthropic and other AI companies, meanwhile, need ever more computing capacity to train and run their models. Debt financing of this scale allows the hardware purchases to proceed without either side tying up tens of billions in cash upfront.

For Broadcom, the arrangement extends a business model built on custom silicon: design chips for a major customer, secure long-term purchase commitments, and line up third-party financing so the customer can pay for the resulting systems. The $60 billion figure underlines how far the amounts involved have moved beyond conventional project financing.

Syndication of the $42 billion senior tranche will show how much capacity banks and institutional lenders have left for AI-related credit. Strong demand would reassure other vendors and developers preparing similar financing packages. Weak appetite, by contrast, would raise funding costs across the sector.

Neither Broadcom, Blackstone, nor Anthropic has publicly commented on the terms. Broadcom shares traded down 2.15% on the news, while Blackstone edged up 0.13% and Nvidia gained 1.09%.

The report did not specify a timeline for closing the syndication or name the full list of banks in the senior tranche.
