OpenAI plans to slash Microsoft's cut to save $50B

Microsoft's $13 billion bet on OpenAI bought it front-row access to the AI revolution and a sweet 20% cut of OpenAI's revenue. But now that the compute bills are hitting the stratosphere, the partnership is getting an expensive rewrite.

OpenAI has told investors it plans to slash Microsoft's revenue share from roughly 20% down to around 8% by 2030, according to a report from The Information. Industry analyses also suggest the cut could land closer to 10%.

The math is staggering. Slicing Microsoft's take could let OpenAI keep more than $50 billion in extra revenue over the coming years. OpenAI plans to funnel every dollar of those savings straight into computing infrastructure, talent, and frontier research.

Equity for cash flow

Microsoft isn't giving up billions in cash flow for free. In exchange for the reduced revenue share, sources say Redmond will receive roughly a one-third equity stake in OpenAI's newly restructured for-profit entity.

Crucially, Microsoft still won't get a board seat. OpenAI's nonprofit board is expected to retain major governance power, potentially holding a $100 billion stake in the new corporate setup.

The renegotiations haven't been smooth sailing. Yahoo Finance previously reported on fractious talks and a ticking clock hanging over the two sides. The companies are still haggling over discounted Azure server pricing and the legal definitions surrounding artificial general intelligence (AGI).

Meanwhile, OpenAI is already hedging its bets. With its API business now topping $1 billion in annual run-rate revenue, the startup recently inked a cloud deal with Oracle to diversify beyond Microsoft's infrastructure. All of this is happening under the watchful eyes of regulators and vocal critics like Elon Musk, who has slammed the company's shift away from its nonprofit roots.

Why it matters

We think this maneuver shows just how brutally expensive building frontier AI has become. Even with billions in revenue on the horizon, handing 20% off the top to Microsoft was an impossible luxury for OpenAI. Reclaiming that $50 billion is less about hitting quarterly profit targets and more about keeping the compute engines running without constant emergency fundraises.

It also rewrites the playbook for Big Tech and AI startups. In 2019, OpenAI needed Microsoft's servers to survive and handed over generous terms. Today, OpenAI has real commercial leverage and is willing to trade equity to protect its operating cash flow.

Trading cash for equity looks smart on paper for Microsoft, giving it massive upside if OpenAI goes public. But it also cements a colder, more arm's-length dynamic. OpenAI is actively shopping for cloud capacity with Oracle and keeping Microsoft outside the boardroom, while Microsoft is building its own in-house AI stack. The alliance remains intact, but the rivalry beneath it is getting louder.
