AMD borrows $4.75bn while sitting on $13bn, and the number matches its Anthropic promise

AMD has raised $4.75bn in the largest US dollar bond offering it has ever done, sold in four tranches with maturities from three to ten years ^[1]. It did this while holding $13.1bn in cash and short-term investments against $3.2bn of debt at the end of June ^[2], a net cash position of about $9.9bn ^[1], so the raise is not about keeping the lights on.

The company's stated purpose is thin. The filing says proceeds are for general corporate purposes, possibly including debt repayment, and AMD has $875mn of bonds maturing next month ^[3]. That is a genuine use, but it absorbs under a fifth of the money raised ^[2].

The commitment that does match the size is one AMD made to a customer. In July it agreed to invest up to $5bn in Anthropic, alongside a partnership to deploy as much as two gigawatts of Instinct MI450 chips to run Claude ^[4]. The bond raise is roughly 95% of that equity ceiling ^[3]. AMD has not connected the two ^[5], and that denial should be carried alongside the arithmetic rather than discarded.

Debt investors were not troubled. The longest tranche priced about a quarter of a percentage point tighter than first indicated, at 0.9 points over Treasuries ^[6], which implies initial talk closer to 1.15 points ^[4]. Six banks ran the deal, among them JPMorgan, Citigroup and Bank of America ^[7]. AMD last came to the investment-grade market in March 2025 for $1.5bn ^[8], making this raise about 3.2 times that size ^[5]. Gross debt, once the maturing notes are retired, moves to roughly $7.1bn ^[6], from a base that was unusually clean for a chipmaker at this scale ^[2].

For anyone buying accelerators, the operative change is not the coupon. It is that AMD has moved from selling into demand to co-funding it. A supplier that holds equity in a customer and has underwritten two gigawatts of deployment has a stake in that customer's survival, which cuts both ways: it makes supply commitments more credible and it makes the supplier's reported growth harder to read as independent validation. The pattern is not AMD's invention. Google has run the same circular arrangement with Anthropic ^[9], and Nvidia has gone further, discussing guarantees over OpenAI's data centre debt ^[10].

The underlying business is real. Analysts expect AMD revenue to rise 47% this year to more than $51bn, helped by the Anthropic agreement and a separate deal with Microsoft ^[11]. The financing sits inside a larger shift: Big Tech's AI debt has passed $350bn, with investment-grade issuers now a routine part of that total rather than an exception ^[12]. AMD's raise is about 1.4% of that figure ^[7]. A spokesperson said the company is "committed to maintaining its strong financial balance sheet" ^[13], which the June numbers support ^[2].

Three things to watch. First, whether future filings show actual drawdowns against the $5bn Anthropic commitment ^[4], which would settle the question AMD is currently leaving open. Second, whether the two gigawatts of MI450 capacity ^[4] converts into disclosed revenue on a schedule that supports the 47% growth expectation ^[11]. Third, whether AMD returns to the bond market again inside a year, having stretched from $1.5bn to $4.75bn between visits ^[8][1]; a third, larger trip would say the customer commitments are no longer fundable from operating cash.
