CoreWeave Prices Upsized $3.7 Billion Convertible Notes Offering

CoreWeave has priced an upsized $3.7 billion private offering of convertible senior notes due 2033, increasing the deal from the $3.0 billion base size announced a day earlier. The notes carry a 2.875% annual interest rate and are expected to settle on September 22, 2026, subject to customary closing conditions.

The AI infrastructure company also granted the initial purchasers an option to buy up to another $500 million of notes during a 13-day period beginning with the initial issuance date. If that option is exercised in full, the total principal amount sold could reach $4.2 billion.

The financing gives CoreWeave a large new pool of capital while setting terms that could eventually result in shares being issued if holders convert. The initial conversion price is about $97.85 per share, a 22.5% premium to CoreWeave’s $79.88 closing price on September 17.

The offering grew by $700 million before pricing

CoreWeave first disclosed plans on September 17 to sell $3.0 billion of convertible senior notes due 2033. Its Form 8-K filed with the Securities and Exchange Commission said the company planned to use part of the proceeds to pay for capped call arrangements and the rest for general corporate purposes. The filing also disclosed the additional $500 million purchaser option.

The final $3.7 billion size is therefore $700 million larger than the original base offering. CoreWeave estimates net proceeds of about $3.64 billion after purchaser discounts and commissions but before estimated offering expenses. If the additional-note option is exercised in full, estimated net proceeds would rise to about $4.14 billion.

About $498.8 million of the expected proceeds is earmarked for the cost of the capped call arrangements entered into alongside the offering. CoreWeave plans to use the remainder for general corporate purposes. The company has not assigned those remaining proceeds to a single named project in the pricing announcement, so the financing should not be treated as being specifically earmarked for one data center, customer deployment or acquisition.

The notes are senior unsecured obligations of CoreWeave and will be guaranteed by the wholly owned subsidiaries that guarantee several of the company’s existing senior and convertible notes. Interest will be paid semiannually on April 1 and October 1, beginning April 1, 2027. The notes mature on April 1, 2033 unless they are earlier repurchased, redeemed or converted under their terms.

The conversion terms start at about $97.85 per share

The initial conversion rate is 10.2194 shares of CoreWeave Class A common stock for each $1,000 principal amount of notes. That produces the initial conversion price of roughly $97.85 per share. The rate is subject to adjustments under specified circumstances.

Before January 3, 2033, holders may convert only when specified events occur or during specified periods. From that date until shortly before maturity, holders can convert without those earlier restrictions. CoreWeave may settle a conversion in cash, Class A shares, or both, depending on the terms governing the notes and the company’s election.

The 22.5% conversion premium matters because it establishes the initial share-price level embedded in the convertible security. It does not mean the stock is expected to reach that price, nor does it guarantee that investors will convert. The economic outcome will depend on CoreWeave’s share price, the notes’ market value, interest payments and the conversion provisions over the life of the securities.

CoreWeave paired the notes with capped call arrangements designed to reduce potential dilution from conversions or offset certain cash payments above the principal amount. The company said those arrangements initially cover the shares underlying the notes. The protection is limited by the cap built into the contracts, so it does not eliminate all possible dilution if CoreWeave’s stock rises far enough.

The company priced the notes under Rule 144A, meaning the securities are being offered to persons reasonably believed to be qualified institutional buyers rather than through a broadly registered public offering. The notes and related guarantees have not been registered under the Securities Act for this sale.

CoreWeave has repeatedly tapped debt and convertible markets

The September financing is not CoreWeave’s first large convertible debt sale. In April 2026, the company priced $3.5 billion of 1.75% convertible senior notes due 2032, also upsized from a $3.0 billion base offering. That April deal followed a $2.25 billion convertible-note offering due 2031 priced in December 2025.

The repeated use of convertible debt gives CoreWeave access to capital at coupons below many of its conventional unsecured notes, but the structure introduces a different tradeoff. Investors accept a lower cash interest rate in exchange for conversion rights tied to the company’s stock. For existing shareholders, that creates potential future dilution if the notes convert into equity, which is one reason CoreWeave has used capped calls alongside its convertible offerings.

CoreWeave has also used conventional senior notes and large secured financing facilities as it builds out the infrastructure required for AI computing workloads. The new 2033 notes sit within that broader financing structure rather than replacing the company’s existing borrowings.

The immediate next step is settlement, currently scheduled for September 22. Until then, closing remains subject to customary conditions. Once issued, the 2.875% notes will extend CoreWeave’s convertible debt maturity schedule to 2033 and add as much as $4.2 billion of principal if the initial purchasers take the full additional allotment.
