Alphabet is doing something it has never done before: selling bonds denominated in Japanese yen. The move opens a fresh pipeline of capital for a company that plans to spend at least $180 billion on AI infrastructure next year alone.

The inaugural yen bond offering features maturities spanning 3 to 30 years, with Bank of America and Morgan Stanley leading the deal. The issuance could total as much as ¥500 billion, roughly $3.2 billion.

Why yen, why now? Japan’s bond market has long been a magnet for top-tier corporate borrowers. The reason is straightforward: cost. Japanese interest rates remain historically low compared to US rates, even after the Bank of Japan’s recent tightening cycle. For Alphabet, borrowing in yen can mean paying significantly less in coupon payments than issuing equivalent dollar-denominated debt.

The AI arms race demands creative financing. Alphabet’s projected capital expenditures for 2026 land between $180 billion and $190 billion. That spending is primarily earmarked for AI-related investments, including data centers and custom silicon chips designed to train and run increasingly powerful models. Each data center costs billions to construct, equip, and power. Alphabet has also invested heavily in its Tensor Processing Units (TPUs), which compete with Nvidia’s GPUs for AI workloads.

For equity holders, this avoids dilution entirely, unlike a secondary stock offering. GOOGL stock has climbed 153% over the last 12 months, reaching $400.80 per share.

However, there’s a currency risk: If the yen strengthens against the dollar before these bonds mature, Alphabet’s repayment costs rise in dollar terms. By locking in long-dated funding now, Alphabet is betting that the AI infrastructure it builds today will generate returns for decades.
