With more than $1 trillion (€900 billion) pouring into the artificial intelligence (AI) build-out, US tech giants are now competing with governments and companies in Europe for the same investment capital. Four of the Big Five hyperscalers — Amazon, Google-owner Alphabet, Meta and Oracle — have issued around $250 billion in bonds in dollars since the beginning of 2025, according to a tally of filings to US financial regulators by AI Industry Reviews, an independent platform that evaluates AI tools. They have sold a further €37 billion ($41 billion) of bonds in euros.
Recently, Microsoft, the last of the Big Five to hold back, joined the AI borrowing spree with a $25 billion bond sale, all in dollars. Next year, Goldman Sachs projects that total new AI hyperscaler bond sales are expected to reach $420 billion. About €60 billion will be issued in euros, according to Dutch bank ING.
That is unwelcome news for European companies and countries like France, Germany and Italy, whose sovereign bond yields have risen sharply in recent months and are already straining public finances. With public debt at 119% of gross domestic product (GDP) and a deficit still running above 5%, France is already paying a sizable risk premium on its debt. Over the past six months, yields on French 10-year bonds have climbed from roughly 3.7% to nearly 5%.
The French government's interest bill is set to rise from €79 billion currently to €91 billion next year and over €100 billion by 2028. Based on these figures alone, France's Finance Ministry needs to find tens of billions of euros in additional cuts, tax hikes, or more borrowing by the end of the decade.

Writing in a blog post, they also questioned whether the bloc's financial markets can "smoothly handle such large and concentrated debt inflows and warned of a "potential spillover to the sovereign and supranational segment of the bond market." That means governments and international lenders such as the European Union and the European Investment Bank could also end up paying more to borrow.
Viktor Hjort, global head of credit strategy at the French bank BNP Paribas, described the phenomenon as "bond abundance." Hjort told DW that the presence of the hyperscalers in the euro bond market is "already high enough to create competition" within the corporate sector and "between corporates and governments for available fixed income funds." These are investment funds that mostly buy bonds, which pay regular interest. Bond yields jumped again last month, driven by rebounding energy prices linked to the Iran war and France’s political crisis, which Hjort said further revealed the growing competition for capital, as government and company borrowing costs rose together. Normally, nervous investors move into government bonds during uncertain times, which pushes their borrowing costs down.
Goldman Sachs warned last week that rising interest costs were starting to hurt earnings at European companies. Among firms in the Stoxx 600 — an index of 600 large, mid-sized and small companies across Europe — Goldman found that interest costs as a share of sales have risen by nearly half since 2022. The bank's analysts said this had cut earnings by more than 5% over the same period.
