Sam Altman pushed out of OpenAI in 2023, now faces a new fight: a $1 trillion IPO target colliding with SoftBank's 2027 loan deadline.
OpenAI wants to go public at a $1 trillion valuation, and that ambition is now bumping up against SoftBank's own calendar. It is a very different story from the one that made headlines back in November 2023, when Sam Altman was pushed out of OpenAI by its board before being reinstated days later. This time the tension is financial, not personal, but it still carries real consequences for shareholders of Microsoft and Nvidia, both of which have deep ties to OpenAI's fortunes.
A trillion dollar target meets a 2027 deadline
OpenAI filed a confidential S-1 with the Securities and Exchange Commission in June. The company's private post money valuation sits around $852 billion following a funding round completed in March 2026. Reported figures put 2025 revenue near $13 billion, with 2026 revenue running near $2 billion a month, numbers strong enough to justify a rich multiple but not comfortably so. Altman has reportedly told investors he won't take OpenAI public below the $1 trillion mark, meaning the IPO either clears that threshold or it waits.
Meanwhile, SoftBank is working against its own clock. It arranged an unsecured $40 billion bridge loan to help fund its expanded OpenAI stake, and that loan matures in March 2027. Bridge financing like this is meant to carry a company to a specific liquidity event, and in this case that event appears to be an OpenAI IPO landing sometime in the fourth quarter of 2026 or the first quarter of 2027. If public investors won't support a trillion dollar price tag by then, SoftBank faces a choice: refinance on worse terms, or watch OpenAI list at a lower valuation than Altman wants.
What years after Altman was pushed out of OpenAI looks like now
Three years removed from that boardroom upheaval, OpenAI looks like a company with far bigger stakes riding on its next move than an executive shakeup. Microsoft owns roughly 27% of OpenAI after committing about $13 billion in earlier funding, and it is reportedly in talks to add just under $10 billion more in the current round. A trillion dollar listing would turn Microsoft's stake into one of the most valuable strategic holdings any public company has ever carried, reinforcing the Azure and Copilot growth story it has built around OpenAI's technology.
The flip side is dilution and timing risk. If SoftBank's need to refinance forces OpenAI toward the public markets before enterprise AI economics have settled down, Microsoft could end up with a headline grabbing valuation gain attached to a partner whose stock swings unpredictably, and with investors asking harder questions about how much capital the whole arrangement actually requires.
Nvidia's chips are the constant in the equation
Nvidia has put roughly $30 billion into OpenAI equity, part of more than $40 billion it has funneled into AI labs including Anthropic. OpenAI's infrastructure roadmap calls for deploying at least 10 gigawatts of Nvidia systems, with 1 gigawatt targeted for the second half of 2026 alone. That build out is really the core of Nvidia's exposure here: demand for its graphics processing units doesn't depend on OpenAI's IPO going smoothly, but a successful trillion dollar listing would amplify the mark to market gains on Nvidia's stake. A disappointing reset in OpenAI's valuation, on the other hand, would draw attention to how much of the capital flowing through the AI industry right now is circular, with chipmakers investing in the very labs that buy their chips.
Where the SoftBank clock and Altman's price floor actually collide
The friction is straightforward even if the numbers are enormous. Altman wants a floor of $1 trillion. SoftBank wants its $40 billion loan handled well before it comes due in March 2027. Those two goals only align if OpenAI's IPO happens on a timeline that satisfies SoftBank and at a price that satisfies Altman, and there is no guarantee public markets will cooperate with both conditions at once. For Microsoft and Nvidia investors, the outcome will shape how two of the most closely watched holdings on their balance sheets get valued for years to come.
