Alphabet is seeking to raise up to $25 billion through a new round of dollar-denominated investment-grade bonds, testing investor appetite for AI-related debt and sending long-term U.S. Treasury yields higher, adding pressure to markets.
The bond sale, reported via sources, is split into 10 parts with maturities ranging from two to 40 years. The longest tranche’s initial price guidance is set at about 155 basis points above U.S. Treasuries. The final size remains undetermined.
Following the news, Treasury yields rose 3 to 4 basis points across the curve, with long-dated bonds leading losses. The 10-year yield climbed to around 4.65%, while the 2s10s and 5s30s spreads widened to their session peaks.
Timing Raises Questions
The timing of this bond sale is particularly sensitive. About two weeks ago, Alphabet raised its 2026 capital expenditure forecast to up to $205 billion, more than double its 2025 spending level, reigniting doubts about returns on AI investments. Meanwhile, short-term Treasuries faced additional pressure: a report suggested Federal Reserve Chair Waller is prepared to hike rates in September if upcoming inflation data runs hot, pushing short-term yields higher.
Cooling Demand for AI Bonds
Alphabet’s bond offering comes amid cracks in investor confidence in AI infrastructure financing. Last week, a BlackRock-affiliated entity issued $12.5 billion in bonds for a Meta Platforms data center project in Texas, which saw lukewarm initial demand. A similar Amazon bond sale also faced tepid interest. New AI-related bonds from firms including SpaceX have seen secondary market spreads widen.
Since the start of 2025, big tech companies have raised over $350 billion in bond markets, with Alphabet and Amazon leading the pack. Alphabet alone has issued over $50 billion in bonds in the first half of 2026, across currencies including Swiss francs, pounds, euros, Canadian dollars, and yen, and completed an $85 billion equity offering about two months ago.
Rising Capex Strains Cash Flow
The surge in capital expenditures is leaving a mark on Alphabet’s financials. Massive capex has dragged the company to its first quarter of negative free cash flow since its IPO, fueling fears of an early “negative cash flow era” for mega-cap tech firms. Alphabet has also filed to issue up to $40 billion in Class A and Class C shares, further bolstering its capital reserves for AI infrastructure spending.
In bond markets, Alphabet’s issuance plan, combined with potential Fed rate hike expectations, acted as a dual driver of Treasury pressure on the day. Long-end yields were pushed higher by supply pressures, steepening the yield curve. Rate markets are still pricing in about 15 basis points of a September rate hike, with cumulative expectations of around 33 basis points by year-end, reflecting high uncertainty over monetary policy.
For fixed-income investors, balancing the supply shock from AI capital expenditure expansion with potential rising rate risks is emerging as a key challenge.
