Who Owns CoreWeave and Who Actually Controls It?

Quick Answer

CoreWeave is owned by its public shareholders, but co-founders Michael Intrator, Brian Venturo, and Brannin McBee retain effective control through super-voting Class B shares. CoreWeave is not a subsidiary of NVIDIA, Microsoft, Magnetar, or another parent company.

• CoreWeave trades on Nasdaq under the ticker CRWV.
• Michael Intrator held 38.70% of total voting power as of April 15, 2026.
• Brian Venturo and Brannin McBee held 20.30% and 14.59% of voting power.
• Magnetar-managed funds were the largest disclosed outside Class A holder.
• NVIDIA owned 10.66% of Class A stock, but only 3.27% of total voting power.

Who Owns CoreWeave Today?

CoreWeave’s ownership is divided between public Class A shareholders and founders holding Class B stock. The founders do not own every share, but the company’s dual-class structure gives them far more voting influence than their economic ownership alone would suggest.

Class A shares carry one vote each. Class B shares carry ten votes each. CoreWeave’s founders collectively held all outstanding Class B shares covered by the company’s April 2026 proxy ownership table.

Founder ownership and voting control

Together, CoreWeave’s executive officers and directors controlled 72.32% of total voting power. That gives the leadership group substantial influence over director elections, corporate governance, and other matters submitted to shareholders.

These figures represent beneficial ownership, which can include shares obtainable through options, awards, trusts, or other arrangements within the disclosure period. They should not be read simply as unrestricted shares held personally.

Largest disclosed outside shareholders

Magnetar controlled more disclosed Class A shares than any founder individually, but it did not control CoreWeave. Its one-vote Class A stock carried much less voting weight than the founders’ ten-vote Class B shares.

CoreWeave Company Snapshot

As of April 30, 2026, CoreWeave reported approximately 447.6 million Class A shares, 98.0 million Class B shares, and no outstanding Class C shares.

How Did CoreWeave’s Ownership Evolve?

CoreWeave began in 2017 as Atlantic Crypto, a cryptocurrency-mining operation founded by Intrator, Venturo, McBee, and Salanki. The company accumulated graphics processing units and later redirected that computing capacity toward cloud services and artificial intelligence workloads.

Private funding accelerated the transition. Magnetar became an important financial backer, while NVIDIA invested in CoreWeave and developed a broader supplier, customer, and strategic relationship with the company. Other investors participated during CoreWeave’s private-company phase, but not all remained reportable owners after the IPO.

CoreWeave completed its initial public offering in March 2025. The listing allowed outside investors to buy Class A shares while the founders retained Class B stock with ten votes per share. This preserved founder control after the company entered the public market.

In January 2026, NVIDIA invested another $2 billion, purchasing CoreWeave Class A stock at $87.20 per share. The transaction added roughly 23 million shares and nearly doubled NVIDIA’s position.

Does NVIDIA Own CoreWeave?

NVIDIA is a major shareholder and strategic partner, but it does not own or control CoreWeave.

CoreWeave’s April 2026 proxy listed NVIDIA as the beneficial owner of 47,213,353 Class A shares. That represented 10.66% of the Class A stock but only 3.27% of total voting power because NVIDIA did not hold the founders’ super-voting Class B shares.

The relationship is unusually close. CoreWeave builds its AI cloud around NVIDIA GPUs, sells infrastructure services to NVIDIA, and received major equity investments from the chipmaker. CoreWeave also disclosed that NVIDIA accounted for 17% of its supplier purchases in 2025.

That commercial interdependence can make NVIDIA appear like a parent company. Legally and operationally, however, CoreWeave remains an independent public corporation led and controlled by its founders.

Microsoft and OpenAI are also important customers or business partners, not CoreWeave’s owners. A large contract does not provide corporate control unless it comes with equity or voting rights.

What Is Changing in CoreWeave’s Ownership?

CoreWeave’s economic ownership can change as investors buy or sell Class A shares, employees exercise equity awards, and the company issues stock to finance expansion. Voting control changes more slowly because it is concentrated in Class B shares.

Transfers of Class B stock generally cause those shares to convert into Class A stock, with limited exceptions for approved estate-planning, trust, or charitable transfers. Founder sales can therefore reduce super-voting control over time.

CoreWeave disclosed a March 2026 Rule 10b5-1 plan under which Brannin McBee and related entities could potentially sell or convert several million shares, subject to the plan’s conditions. A plan authorizes possible transactions; it does not prove that every covered share will be sold.

The dual-class structure also has an expiration mechanism. Class B shares must automatically convert no later than May 31, 2032, unless an earlier triggering event occurs. One trigger relates to Michael Intrator no longer devoting substantially all of his working time to CoreWeave.

How Does CoreWeave’s Ownership Compare With Its Rivals?

CoreWeave differs from traditional cloud providers because it is publicly traded yet founder-controlled.

• Amazon Web Services is wholly owned by Amazon.
• Microsoft Azure operates within Microsoft.
• Google Cloud belongs to Alphabet.
• Lambda remains privately held and investor-backed.
• CoreWeave has public shareholders, but its founders hold the dominant voting position.

This structure gives public investors economic exposure to CoreWeave’s AI cloud growth without giving them voting influence proportional to the number of ordinary shares they own.

It would be difficult while the founders retain substantial Class B holdings. Each Class B share has ten votes, compared with one vote for a Class A share.
