Hyperscaler bond issuance has already doubled its 2025 total
Investment-grade bond issuance by the five hyperscalers, the companies running the largest cloud and AI infrastructure, reached 218.1 billion dollars by early October, according to an LSEG FTSE Russell note of 29 October. That is more than double the 107.3 billion dollars issued in the whole of 2025.
The note shows 151.75 billion dollars of 2026 issuance in dollars and 24.65 billion dollars in euros; euro issuance has already overtaken the 15.02 billion dollars of 2025. The five companies had 500 billion dollars of index-eligible debt at the end of August. Their average maturity of 17.27 years sits well above the 10.95 years of the corporate bond index. In two years the hyperscalers' weight in the US corporate bond index has risen from 2.7% to 4.7%. J.P. Morgan estimates the five companies' 2026 capital expenditure at 697 billion dollars.
Pricing is shifting too. According to LSEG, the group's average spread stood at 119 basis points on 30 September, 33 basis points above the index's 86. Since December 2025 the group has widened by about 31 basis points, against just 1 for the index. Oracle's 5-year CDS was at 331 basis points on 21 October. An ECB blog post of 31 August says hyperscalers account for close to 10% of euro-denominated non-financial corporate issuance, with about 40 billion euros of euro bonds outstanding.
This is how the cost-of-capital channel reaches Europe. The ECB says pension funds and insurers are the main buyers of this extended-maturity paper. Demand has softened since mid-2026, and limited balance-sheet capacity risks crowding out other issuers. On 29 October Lagarde said hyperscaler issuance has contributed to the rise in yields at the far end of the curve. The ECB puts the increase in 10-year government bond yields since September at about 35 basis points.
Talay assessment
Bottom line
The financing of AI investment has moved from equity to bond markets and has sharply enlarged the supply of extended-maturity debt. The group's 33 basis point spread over the index shows investors are no longer absorbing that supply without a premium. In Europe, the insurers and pension funds that buy this paper are also the buyers of highly indebted sovereigns. That competition for balance sheet is one source of pressure at the far end of the curve.
Likely effects
- Extended-maturity yieldsNegative1–6 months
Heavy supply with a 17-year average maturity pushes up the term premium at the far end of the US and euro curves; Lagarde flagged the effect explicitly on 29 October.
- Insurer and pension balance sheetsUncertain1–6 months
Abundant supply is a yield opportunity for institutions seeking high-quality duration, but limited balance sheet may shrink the share left for heavily indebted issuers such as France.
- Cost of AI investmentNegative6 months+
The group's spread has widened by about 31 basis points since December 2025, raising the financing cost of 697 billion dollars of capital expenditure.
