Alphabet launches €6B euro bond sale to test AI-era tech debt appetite

Alphabet is back in the euro market, and it's not being shy about it. The Google parent launched a €6 billion ($6.7 billion) bond sale on Monday, according to a memo from one of the deal's managers seen by Reuters, with order books swelling past €17 billion. The sale is spread across seven tranches, six fixed-rate and one floating-rate, with maturities stretching from 2 to 19 years, per an SEC filing. Pricing is expected later Monday.

It's the second euro-denominated trip to market for Alphabet this year, following a €9 billion, six-tranche sale in May and a rare 100-year sterling bond in February. The timing is the interesting part: investors have spent weeks souring on the AI spending spree, and tech stocks and bonds have taken the hit. That trade wobbled again after disappointing quarterly results from Alphabet and Amazon, two of the biggest data-centre spenders.

Alphabet knows what that skepticism looks like up close. Its shares plunged more than 12% last Thursday — the worst single day on record — vaporizing roughly $500 billion in market value as Google Search growth came in slower than expected and cash burn rattled shareholders. For the full year, the company is staring down capital spending of as much as $205 billion, and as of September 30 it had signed data-centre-heavy leases that haven't started yet, carrying $130.5 billion in future payments that don't show up on its balance sheet.

Alphabet says the net proceeds will go toward general corporate purposes, which may include paying down existing debt. Barclays, BNP Paribas and Deutsche Bank are running the books as joint book-running managers, the filing shows. The company's dollar-denominated 4.1% bond due in 2031 barely budged Monday, sitting at about 95.43 cents on the dollar.

There's a bigger pattern forming here. Analysts expect major tech players to lean harder on Europe's deep, liquid debt markets to bankroll infrastructure buildouts, even as US investors get twitchy about the returns on all that AI money. Microsoft stood out in the quarter as the only Big Tech name actually generating cash, which is a lonely place to be.

Wall Street, for now, isn't treating the bond sale as a red flag. Alphabet shares ticked up about 1% in premarket trading, a small bounce after a brutal October that saw its US-listed stock drop nearly 19% — its worst monthly performance ever recorded.
