Alphabet's Century Bond Sparks Debt Concerns in AI Race
Alphabet issued a rare 100-year sterling bond as part of a roughly $20 billion multi-tranche, multi-currency borrowing program to fund data‑centre and AI infrastructure buildouts. The £1 billion ($1.37 billion) century bond was almost ten times oversubscribed and priced about 120 basis points above 10‑year gilts. Strategists and fund managers told CNBC the deal highlights historically high levels of tech-sector borrowing, broadens Alphabet’s lender base by tapping insurance and pension demand, and raises concerns about market froth and long-term credit risk as hyperscalers scale AI capex. Commentary from market participants contrasted corporate long-dated debt risk with sovereign issuance and warned that high leverage amid rapid technological change could create winners and losers in the sector.
A major platform (Alphabet) issued an uncommon 100-year corporate bond and a large multi-currency $20B borrowing program to fund AI/data‑centre capex, signalling significant financing trends, lender-base shifts and potential credit-market risks that affect the wider tech and infrastructure ecosystem.

Alphabet's Bond Bonanza Surpasses $30 Billion Mark
Alphabet is finalizing a global bond issuance exceeding $30 billion, an increase from an initial $20 billion offering earlier in the week, according to people familiar with the deal. The company tapped European markets to raise roughly $11 billion in sterling and Swiss francs. The move comes as Alphabet projects up to $185 billion in capital expenditures for the year and follows previous large debt sales (a $25 billion bond sale in November and long-term debt that rose to $46.5 billion in 2025). Other major tech firms including Oracle, Meta, Amazon and Microsoft are also tapping debt markets or planning large offerings to fund data-center and AI investments.
Wall Street Favors High-Yield AI Bonds
Major cloud hyperscalers have issued a surge of corporate debt to fund AI infrastructure, creating attractive yields for income investors but adding supply that pressures sovereign bond yields. As of August 20, 2026, Alphabet, Amazon, Meta Platforms and Oracle had issued nearly $223 billion in bonds, per LSEG. Market participants say yields on hyperscaler bonds range roughly 4.75%–8% depending on issuer and maturity; many issues are investment grade but require issuer-specific credit analysis. Rising supply has contributed to higher Treasury yields and reflects expectations of continued issuance to finance AI buildouts.
Amazon issues first sterling bonds to fund AI investments
Amazon has successfully placed its first-ever sterling-denominated bonds, raising £4.25 billion to support its massive AI and cloud infrastructure investments. The issuance was oversubscribed more than two times, attracting orders exceeding £10.65 billion. The bonds were divided into four tranches with maturities of three, six, twelve, and nineteen years, offering yields ranging from approximately 5.2% to 6.7%. This move is part of Amazon's broader strategy to diversify its funding sources beyond the US dollar, having previously issued bonds in euros, Swiss francs, and Canadian dollars. The capital will help fund Amazon's planned capital expenditures of around $200 billion for 2026, which include investments in AWS, data centers, chips, and network infrastructure. The issuance reflects a broader trend of Big Tech companies increasingly relying on bond markets to finance their AI buildout, with major hyperscalers having already issued over $200 billion in corporate bonds in 2026.
