$300 Billion Over Five Years: OpenAI and Oracle Sign One of History's Largest Cloud Deals

Per the WSJ and Reuters, OpenAI signed a roughly $300 billion five-year cloud compute contract with Oracle in September 2025, with supply starting in 2027 — one of the largest cloud contracts ever. Oracle shares surged on the news as its remaining performance obligations ballooned.

Why Oracle Won the Deal#

Outside the big-three clouds, Oracle's chip was its willingness to sink heavy assets: purpose-building data centers for OpenAI (including the Stargate Texas campus) and accepting long payback cycles. For a company that had spent years outside the AI narrative, this was the ticket back to the table — and the RPO-driven stock surge was the market voting, with real money, that AI demand can be locked in ahead of time.

$13B Revenue vs $60B a Year: The Math#

The core skepticism is ability to pay: OpenAI's 2025 revenue of roughly $13 billion sits far below the contract's ~$60 billion annual run rate. The only supporting logic is hypergrowth plus continued fundraising — the same quarter delivered the PBC restructure clearing funding constraints and the $100B Nvidia LOI (see our coverage). These arrangements presuppose each other, and share each other's risk: if any link grows slower than planned, the whole chain tightens.

The AI Capital Triangle Takes Shape#

Connect the year's deals: the chipmaker (Nvidia) invests in the model lab, the model lab (OpenAI) signs cloud mega-contracts, the cloud (Oracle) buys the chips — capital, chips and compute loop inside the triangle, and each party's orders are another's revenue. The triangle absorbs short-term shocks while binding systemic risk tighter (see the loop analysis in our Nvidia-OpenAI LOI coverage).

Our Take#

Mega compute contracts are reshaping the industry: for clouds, an AI anchor deal is a valuation-rerating switch; for model labs, locking compute is locking the future. But read these headlines carefully: contract totals are multi-year pledges, not current cash flow. The number worth watching is how fast RPO converts to revenue each quarter — that is the litmus test of whether the demand is real.
