BNP Paribas, Deutsche Bank and JPMorgan have the mandate. Maturities run from three years to 25 years.
The trade follows Alphabet’s record Swiss issuance in February and Amazon’s $37bn dollar deal in March, and is the latest demonstration that hyperscalers are now multi-currency borrowers.
Amazon is preparing its first-ever Swiss franc bond issuance, Bloomberg reported on Monday, in a six-tranche deal that stretches across three-, five-, seven-, ten-, fifteen- and twenty-five-year maturities.
BNP Paribas, Deutsche Bank, and JPMorgan have been mandated to run the books. Amazon has not yet disclosed the size of the trade; pricing is expected later this week.
The trade is the most visible sign yet that the largest US hyperscalers have crossed a threshold in their funding strategy. A US dollar bond programme is no longer sufficient on its own.
The capital required to fund AI infrastructure has become large enough that Big Tech treasurers are now actively diversifying into euros, sterling, and Swiss francs, often within the same multi-currency programme, to broaden their investor base and to capture pockets of demand that the US market alone cannot satisfy at acceptable rates.
Amazon’s path into the Swiss market follows a well-trodden one. Alphabet sold more than CHF 2.75bn (roughly $3.6bn) across five maturities in February as part of a multi-currency drive that included sterling, euro, and a rare 100-year US dollar bond.
That Swiss tranche was the biggest-ever corporate bond sale in the Swiss market. Caterpillar and Thermo Fisher Scientific have both used the same market in the past eighteen months.
What Amazon adds to that list is scale: with roughly $200bn of capex planned for 2026 according to CEO Andy Jassy’s recent comments, the company’s incremental funding requirement runs to multiple tens of billions per year.
Six tranches across the Swiss curve is consistent with a treasurer trying to lock in long-duration capacity rather than to fund a specific project.
On 10 March, Amazon raised about $37bn across eleven tranches in the US bond market. That trade was followed shortly afterwards by a EUR 14.5bn deal split across multiple tenors.
The combined dollar-and-euro raise was, at the time, the largest single funding event in the company’s history. Demand on the dollar trade was reported to have run roughly four times the size sold.
Pricing on the long end came inside Treasury yields by margins that would have been inconceivable for the company a decade ago.
The Swiss franc issuance now extends that pattern into a third currency and a market structure where issuance costs typically run materially below dollar equivalents for similarly-rated borrowers.
The arithmetic behind the issuance is straightforward. Amazon Web Services is growing AI-related revenue at the high end of the hyperscaler range, but the capex required to support that growth is sufficiently lumpy that the company has chosen to pre-fund a significant share through long-duration debt rather than to draw down cash reserves.
That choice is being made simultaneously by Alphabet, Microsoft, Meta and Oracle. Combined hyperscaler debt issuance ran past $121bn in 2025 and is on pace to top that figure by mid-2026; the $650bn of combined Big Tech AI capex now planned for 2026 is the operating-budget number that explains the funding-side urgency.
Investor reception of these trades has been consistently strong. The four largest US hyperscalers all retain credit ratings in the AA range, which gives them access to the deepest pools of institutional fixed-income demand at margins that no private-market financing structure can match.
The largest 2025 trades were oversubscribed by margins that would have looked unusual in any other sector; Amazon’s March dollar trade ran roughly 4x covered.
The Swiss franc market is smaller in absolute terms (the all-currency corporate market clears around CHF 60-70bn a year by Refinitiv tracking), but the rate environment, with Swiss yields running materially below US dollar and euro equivalents, makes it commercially attractive for issuers whose absolute funding needs can be split across currencies.
The currency-strategy logic is genuinely diversification rather than yield optimisation. A multi-currency programme reduces dependence on any single investor base, gives a treasurer flexibility about which tranches to access in periods of regional volatility, and lengthens the average maturity profile by tapping markets where long-duration demand is particularly deep.
Amazon’s choice of a 25-year tranche at the long end of this Swiss deal is consistent with that strategy. Three, five, seven and ten-year tranches give the company belly-of-curve flexibility.
The fifteen and twenty-five-year pieces match insurance and pension demand that is harder to source in equivalent size in dollars.
The wider question, which the cleaner trades of the past three months have made more rather than less acute, is how long the supportive funding environment lasts.
Hyperscaler bond issuance has been running at a pace that even bullish analysts had not modelled at the start of 2025. Morgan Stanley and JPMorgan have estimated that the sector may need to issue as much as $1.5 trillion of additional debt over the coming several years to fund the AI build-out at planned pace.
That figure assumes capex continues to grow on its current trajectory; if AI revenue growth lags those expectations, the credit metrics underpinning the AA ratings could come under more scrutiny.
The cash-generation strength behind Alphabet’s market-cap rise is part of the story that has kept the credit picture intact so far, but it depends on operating cash flow continuing to scale with the build.
Amazon’s specific position remains comfortable. The company generated approximately $100bn of free cash flow in fiscal 2025 against group capex of about $80bn, with the gap funded from existing cash reserves and incremental debt.
AWS’s operating margins have stayed above 30%, the highest in the segment. The credit spread on Amazon’s recent dollar issuance was in line with that of higher-rated peers, and the Swiss franc trade is expected to price comfortably inside the broader US dollar curve.
That Alphabet’s earlier $10bn bond sale, then the company’s largest and cheapest, was, in its time, considered the standard-setting hyperscaler funding event.
Amazon’s current programme is, in dollar terms, several multiples of that size and is unlikely to be the largest such trade for very long.
What the Swiss issuance does not yet answer is whether AI revenue scaling will eventually justify the issuance pace.
Amazon’s bond investors are taking the company’s AWS-plus-retail combined cash-flow profile as collateral for the AI build, not the AI revenue itself, which remains too early in its monetisation curve to support credit metrics on a standalone basis.
That is the same bet Alphabet, Microsoft, and Meta are asking their bond books to take. The premise has worked through 2025 and into 2026.
Whether it works through to the back half of the decade depends on what AWS, Google Cloud, and the various large-language-model product lines deliver in revenue over the same window.
For now, the Swiss tranche prices when it prices, and Amazon adds a fourth jurisdiction to a treasury programme that increasingly looks more like that of a sovereign issuer than a corporate one.
The company has yet to issue in yen. On the current trajectory, that is a question of when rather than whether.
