AMD prices record $4.75 billion bond sale to fund AI infrastructure buildout

AMD has priced $4.75 billion in investment-grade senior unsecured notes, according to people involved in the sale, in what would be the chipmaker’s biggest-ever US dollar bond offering. The deal, priced on August 13, 2026, came in four tranches maturing in 2029, 2031, 2033 and 2036.

The borrowing is aimed squarely at the AI buildout. Proceeds are set to go toward general corporate purposes and AI infrastructure spending, including AMD’s previously committed investment of up to $5 billion in Anthropic, the maker of the Claude models.

Bank of America, JPMorgan, Barclays and Wells Fargo are reported to have led the sale. AMD has not published a first-party announcement of the pricing; the terms rest on financial-press reporting corroborated across multiple outlets.

The offering adds to a wave of AI-linked corporate debt from chipmakers and cloud providers racing to fund compute capacity as demand surges. For AMD, tapping the bond market rather than cash on hand signals how expensive the AI infrastructure race has become, even for a company selling into it.

Whether the note proceeds translate into the promised Anthropic stake and data-center capacity, rather than refinancing and balance-sheet cushion, is what to watch as the tranches settle.
