OpenAI, the company behind ChatGPT, has reached a staggering $500 billion valuation after current and former employees sold approximately $6.6 billion worth of shares, according to Reuters. This represents a sharp jump from its previous $300 billion valuation, underscoring the company’s meteoric rise in the artificial intelligence sector.
The sale, which involved leading investors such as SoftBank, reflects strong global confidence in OpenAI’s future. Analysts suggest that this valuation leap places OpenAI ahead of other tech giants in private markets, showing how rapidly the demand for AI technologies is accelerating worldwide.
A key factor behind the valuation surge is OpenAI’s ambitious Stargate project, a next-generation AI infrastructure initiative. In October 2025, Samsung and SK Hynix announced agreements to supply memory chips for Stargate. According to the South Korean presidential office, OpenAI’s demand could reach nearly 900,000 wafers per month, a scale that cements South Korea’s role in the global AI supply chain. Following the announcement, Samsung’s stock rose 4.7% and SK Hynix surged 12%, reflecting investor enthusiasm over OpenAI’s reliance on Korean chipmakers.
Despite record valuation, OpenAI continues to face steep financial challenges:
| First-half 2025 revenue | $4.3 billion, a 16% increase from the whole of 2024 |
| R&D expenses | $6.7 billion in the same period |
| Cash reserve | $17.5 billion |
| Annual revenue target | $13 billion, with spending near $8.5 billion |
These figures illustrate a high-risk, high-reward profile: while revenue is growing, sustainability will depend on balancing costs with market expansion.
Reports suggest Nvidia may invest up to $100 billion in OpenAI, beginning with an initial $10 billion allocation tied to 1 gigawatt of computing power. The details remain under negotiation, including whether funds will flow into OpenAI’s capped-profit entity or its nonprofit arm. Regardless, such a deal could transform the competitive landscape of AI infrastructure.
In late September, CoreWeave signed a new $6.5 billion contract with OpenAI, expanding total commitments to nearly $22.4 billion. This deal provides critical cloud computing resources for Stargate and highlights the growing importance of specialized GPU infrastructure providers.
Not everyone is convinced the growth is sustainable. James Anderson, a leading UK technology investor, recently warned of signs of an AI stock bubble, comparing the current hype to the dot-com boom. Academic studies also suggest valuations may be anchored more in expectations than proven capabilities, posing risks if adoption slows.
Competition is also heating up. Mira Murati, OpenAI’s former CTO, has launched Thinking Machines Lab, which recently raised $2 billion at a $12 billion valuation. The startup has already released Tinker, an API for fine-tuning large language models, signaling that innovation in AI will not remain concentrated in one firm.
Reaching a $500 billion valuation is both a milestone and a challenge. Investors, partners, and regulators will closely monitor:
