Five of the world’s largest technology companies have collectively raised $159 billion in corporate bonds through early June 2026. That’s not an annual figure. That’s five months.
To put that in perspective, the same group of firms, Alphabet, Amazon, Meta, Microsoft, and Oracle, issued $121 billion for the entire year of 2025. The 2026 pace represents a 47% increase over last year’s full-year total, and we’re barely past the halfway mark.
Who’s borrowing what, and why
Amazon leads the pack with roughly $57 billion in bond issuance, followed by Alphabet at approximately $52 billion. Meta and Oracle each come in around $25 billion. Microsoft rounds out the group.
The capital is flowing almost entirely toward AI-related infrastructure. Data centers, servers, specialized chips, and the vast cooling and power systems needed to keep it all running. Projected AI-related capital expenditures for these firms in 2026 sit between $660 billion and $725 billion. For some of these companies, that spending consumes up to 90% of operating cash flow.
Meta’s $30 billion bond initiative stands out as one of the largest individual tech issuances. Oracle’s $18 billion push is notable given the company’s comparatively smaller revenue base. But perhaps the most eyebrow-raising move belongs to Alphabet, which issued a century bond maturing in 2126. That’s a 100-year bond. The first from a tech firm since 1997.
Alphabet also set records in multiple international markets, including landmark issuances denominated in yen and euros, diversifying its borrowing across currencies and geographies.
Big Tech is reshaping the bond market itself
Technology firms now account for a record 10% to 11.8% of the entire US investment-grade corporate bond market. AI-related borrowing has become one of the most significant segments of the bond market, surpassing even traditional heavyweight sectors like banking by some measures.
Before 2025, the annual bond issuance from these firms was modest, averaging between $20 and $28 billion. The year 2025 marked a pivotal shift with a total issuance of $121 billion. Analysts from major financial institutions including JPMorgan, Morgan Stanley, and Bank of America have projected that total annual bond issues could reach between $140 billion and $300 billion in subsequent years.
What this means for investors
The combined capex projections of $660 billion to $725 billion for a single year dwarf the spending that built out cloud computing infrastructure over the past decade.
For bond investors specifically, the flood of tech paper creates both opportunity and concentration risk. When a single sector grows from negligible to nearly 12% of the investment-grade market in a short span, index-tracking funds and institutional mandates can find themselves overexposed to technology in a way that mirrors equity portfolio risks.
