OpenAI’s Valuation Soars to $500 Billion After Major Share Sale Involving SoftBank

OpenAI, the creator of ChatGPT, has achieved a staggering $500 billion valuation after employees and former staff sold $6.6 billion worth of shares to major global investors, according to a source cited by Reuters. This marks a sharp rise from its previous valuation of $300 billion, signaling the company’s explosive growth in both user base and revenue.

The deal involved sales to a powerful consortium of investors, including Thrive Capital, SoftBank, Dragoneer Investment Group, Abu Dhabi’s MGX, and T. Rowe Price. The company reportedly authorized the sale of more than $10 billion in stock on the secondary market, giving early employees and stakeholders the chance to cash out part of their holdings while maintaining OpenAI’s momentum in private financing rounds.

SoftBank, already a participant in OpenAI’s $40 billion primary funding round, has further strengthened its position with this deal. None of the involved firms immediately commented on the transaction.

Financially, OpenAI continues to outperform expectations. The company brought in around $4.3 billion in revenue during the first half of 2025, which is roughly 16% higher than its total revenue for the entirety of 2024, according to The Information.

The timing of this sale coincides with intensifying competition among global tech giants for AI talent and infrastructure dominance. Meta, for instance, is heavily investing in AI companies like Scale AI, and recently hired its 28-year-old CEO, Alexandr Wang, to spearhead its new superintelligence division—a move highlighting the escalating arms race in artificial intelligence innovation and expertise.

As OpenAI’s valuation hits half a trillion dollars, the company stands at the center of this rapidly transforming landscape—its technology, partnerships, and pace of growth redefining the frontier of modern computing.

Nvidia’s $100B OpenAI deal sparks funding, valuation, and competition questions

Nvidia’s plan to invest up to $100 billion in OpenAI — while also supplying millions of its GPUs to the ChatGPT maker — is unprecedented in the tech sector and raises major uncertainties about finance, competition, and market impact.

Key open questions:

1. Where does the rest of the money come from?

  • Nvidia has pledged $10B per gigawatt for 10 GW of compute, but CEO Jensen Huang estimates $50B is needed per gigawatt (with $35B of that spent on Nvidia hardware).

  • That leaves a massive $40B funding gap per GW. OpenAI has not disclosed how it will raise the remainder.

2. How does this fit OpenAI’s shift to for-profit?

  • OpenAI is transitioning from a nonprofit into a public benefit corporation overseen by its nonprofit parent.

  • Nvidia’s investment may hinge on this structure, but it’s unclear if funding flows to the nonprofit entity or the restructured PBC.

  • Regulatory approval in Delaware and California is still pending.

3. What does it mean for OpenAI’s valuation?

  • Nvidia’s initial $10B tranche is pegged to OpenAI’s current $500B valuation.

  • But there’s no timeline for deploying the full 10 GW or committing the entire $100B. Future investments may depend on OpenAI’s valuation at the time, raising uncertainty about dilution and pricing.

4. How will competition be affected?

  • Nvidia’s chips remain the most coveted resource in AI. By tying up vast capacity with OpenAI, rivals like Anthropic, Google, or even Microsoft could face constraints in access.

  • Competitors like AMD may find it harder to gain traction if Nvidia prioritizes OpenAI, despite Nvidia’s public pledge to “make every customer a top priority.”

5. What does it mean for Oracle?

  • Oracle has signed hundreds of billions in cloud contracts with OpenAI, but analysts question whether OpenAI has the liquidity to pay.

  • Nvidia’s cash infusion could strengthen Oracle’s revenue outlook, reassuring investors and credit agencies like Moody’s, which flagged funding risks.

Big picture:

The deal deepens the interdependence of AI’s leading players — Nvidia for chips, OpenAI for models, Microsoft for software integration, and Oracle for cloud. But it also amplifies antitrust concerns, as U.S. regulators eye whether such alliances foreclose competition in the AI stack.

Musk denies $10B fundraising at xAI after CNBC report

Elon Musk pushed back on Friday against a CNBC report that his AI startup xAI was raising $10 billion at a post-money valuation of $200 billion. “Fake news. xAI is not raising any capital right now,” Musk wrote on X, dismissing claims the firm was in talks with investors.

CNBC had reported that the funds would be used to build massive data centers with Nvidia and AMD GPUs and recruit top AI talent as xAI ramps up to compete with OpenAI’s ChatGPT and Anthropic’s Claude. The company operates the Colossus supercomputer cluster in Memphis, Tennessee, which Musk has described as the world’s largest.

Investor interest in AI firms remains strong despite questions over the sustainability of big tech spending. If true, the $200B valuation would have more than doubled xAI’s reported $75B valuation in July and placed it among the world’s most valuable private companies—behind OpenAI, ByteDance, and SpaceX, but ahead of Anthropic, which recently raised funds at a $183B valuation.

Musk’s denial comes amid conflicting signals. In June, Morgan Stanley reported that xAI had already raised $5B in debt financing alongside a $5B strategic equity investment to expand its infrastructure. While Musk insists no new round is underway, xAI continues to scale aggressively, seeking to establish itself as a rival to OpenAI, which may soon be valued at $500B in a planned stock sale.
