Oracle’s massive AI bet hides a huge warning investors can’t ignore

There is a version of the Oracle story that sounds like triumph. Cloud infrastructure revenue up 121%. A $664 billion backlog. $30 billion in new AI contracts signed in a single quarter. 300,000 GPUs delivered to customers, and management raising the full-year revenue forecast to at least $90 billion. I covered all of that in my previous piece.

Then there is another version that sounds like a warning. Credit default swaps at record highs. The 2056 bonds yielding over 8% for the first time. A force majeure notice delaying payments on the New Mexico Project Jupiter data center. S&P downgrading the firm to BBB, one notch above junk. 

If that final downgrade comes, $120 billion of Oracle bonds would be automatically removed from investment-grade indexes, according to a Seeking Alpha analysis.

Both versions are simultaneously true. That tension is the Oracle story in 2026, and it matters for anyone trying to understand how the entire AI infrastructure buildout is being financed.

The cash flow picture that is scaring bond markets

Oracle spent approximately $28.5 billion on capital expenditure in Q1 fiscal 2027 against quarterly revenue of $19.35 billion. Free cash flow for the trailing twelve months through August 2026 is -$28.72 billion, according to Alpha Spread.

That number looks catastrophic until you understand what is driving it. Oracle’s operating cash flow remains strongly positive before the massive growth spending on GPUs, power infrastructure, and new data centers. The negative free cash flow is largely the result of discretionary investment against a contracted backlog, not a deterioration in the underlying business.

Now, the bull case: once Oracle slows its growth capex engine, the company could return to generating substantial free cash flow. Its underlying software and support business, while shrinking as a share of revenue, still carries exceptional margins. And the Oracle Cloud Infrastructure (OCI) buildout represents heavy upfront investment to support a multi-year revenue stream.

The bear case is that Oracle has yet to give investors a clear timeline for when free cash flow will turn positive again. 

Management expects fiscal 2027 net cash capex to approach $70 billion, against roughly $90 billion to $95 billion in reported capex, according to the Q1 2027 Earnings Call Transcript. At that scale, Oracle needs sustained access to external financing to keep the buildout going.

The bond market is charging Oracle for that uncertainty. Five-year credit default swaps for Oracle have reached levels far above the investment-grade average, according to a Seeking Alpha report.

Latest Goldman data via Reuters show that AI-related issuers are paying about 115 basis points on new debt versus 78 basis points for the broader investment-grade market. But Oracle’s situation is more acute than the average.

How Oracle is trying to manage the financing problem

The company is not ignoring the issue. Two structural approaches are cutting down its capital burden.

  1. Customer prepayments. Customers increasingly fund hardware purchases themselves through bring-your-own-hardware arrangements. In Q4 fiscal 2026, approximately $75 billion in AI infrastructure contracts were structured primarily through prepayments or BYOH structures. Q1’s new contracts, management said, did not require additional Oracle capital to fulfill.
  2. The Apollo and Blackstone $35 billion AI purpose vehicle I covered when reporting on Broadcom — Oracle is using similar third-party financing structures to keep specific deployments off its direct balance sheet.

If customers fund a large portion of their own infrastructure, Oracle can grow OCI dramatically without proportional increases in its own spending. I think that is the best-case scenario for the capital structure concern.

Oracle Cloud Infrastructure revenue is up 121%, with a $664 billion backlog and $30 billion in new AI contracts signed in a single quarter.

The business transformation that changes how Oracle should be valued

The deeper issue Morgan Stanley has been wrestling with, as I covered in the Sep. 10 earnings note, is that Oracle is becoming a fundamentally different company.

Software revenue fell 3% in Q1 fiscal 2027. The high-margin, asset-light software business that defined Oracle’s economics for decades is shrinking as a proportion of the total. 

Growth is now being driven by cloud infrastructure, which requires significant physical capital for every incremental dollar of revenue.

Oracle’s long-term margin target for Oracle cloud infrastructure (OCI) is above 30%, with high-20% returns on invested capital for mature data centers. If Oracle hits those targets, this capex cycle could look like one of the most profitable infrastructure investments in technology history.

If they are not achieved — if utilization ramps slowly, if energy and GPU costs remain elevated, if customers negotiate down pricing as more supply comes online — the math looks very different.

The $664 billion backlog provides revenue visibility. It does not provide equal visibility into the economics of converting that backlog into cash. 

You see that gap between contracted revenue and actual free cash flow? That is the question Oracle’s bond market is pricing, and the one equity investors need to think carefully about before treating the 121% OCI growth number as the complete story.
