Amazon sells $25B in bonds to fund $200B AI data center build

Amazon raised $25 billion in bonds in early July to finance a $200 billion data center build-out, the largest single-year capital commitment by any hyperscaler, as CEO Andy Jassy bets the cloud business on AI demand that has yet to produce matching revenue.

"We have been through this cycle with the first big AWS growth wave, and we like the results," Jassy told analysts on the Q1 earnings call, drawing a parallel to the 2014-2017 period when Amazon's infrastructure spending preceded a decade of cloud dominance.

The bond sale brings Amazon's long-term debt to $119.1 billion, up from $65.6 billion a year earlier, while trailing free cash flow collapsed 95 percent to $1.2 billion. AWS grew 28 percent year over year in the first quarter at a 37.7 percent operating margin, its fastest pace in 15 quarters, and carried a $364 billion contracted backlog at quarter-end. Trainium, Amazon's custom AI chip, alone holds $225 billion in revenue commitments.

The spending comes as Moody's warned that "unprecedented" hyperscaler capital expenditures threaten credit quality across the sector, citing $1.2 trillion in 2026 data center commitments and $460 billion in direct debt across six companies. Amazon's stock fell 6.5 percent in the week after Jassy disclosed the $200 billion plan, closing at $233.66.

The Bond Math Behind the Build

Amazon's $25 billion bond issuance, completed in early July, shows the scale of its AI infrastructure ambitions. The company is spending at a pace that exceeds its prior peak in 2022, when capex hit $63.6 billion and free cash flow ran negative $16.9 billion. Within two years, operating cash flow reached $139.5 billion and net income climbed to $77.7 billion, a pattern Jassy is betting will repeat. The debt carries interest expense of $800 million, a manageable cost against AWS's operating income of roughly $30 billion annualized. Amazon's interest coverage ratio stands at 35 times, and net debt-to-EBITDA is 0.45.

The Credit Risk Debate

Moody's warning has injected a note of caution into the capex cycle. The rating agency said heavy capital spending relative to revenue will lead to declining free cash flow and hurt leverage ratios, particularly if the expenditures are debt-financed. Meta disclosed $500 billion in AI-related commitments, with $46 billion in off-balance-sheet exposure through a variable interest entity structure. S&P downgraded Oracle in part because more than 50 percent of its remaining performance obligations depend on OpenAI, an unrated private company. Nvidia is in talks to guarantee $250 billion of OpenAI debt, a move that would test Moody's willingness to put Nvidia's AA rating on review.

Amazon's advantage lies in the diversity of demand backing its capex. AWS's $364 billion backlog includes commitments from thousands of enterprise customers, not just two or three AI labs. Trainium's $225 billion in commitments are contracted, not speculative. The advertising business, now at a $70 billion trailing revenue run rate, provides a second high-margin cash flow stream that offsets the infrastructure spend.

Analysts remain broadly bullish. Of the 62 analysts covering Amazon, all rate it a buy or strong buy, with an average price target of $313.13, implying 34 percent upside from the post-announcement low. The stock trades at 30 times trailing earnings and 29 times forward earnings, with a return on equity of 24.3 percent.

The question is not whether Amazon can afford $200 billion in capex — it can, with 35 times interest coverage and a 0.45 net debt-to-EBITDA ratio. The question is whether AI revenue materializes on a timeline that justifies the spending. Jassy has said AWS data center assets carry 30-plus-year useful lives and chips carry five to six years, meaning the investment horizon is measured in decades, not quarters. For investors willing to look past the near-term cash flow compression, the pattern of prior capex cycles suggests the compounding on the other side has historically rewarded patience.
