A data center supported by CoreWeave Inc. is preparing for a $3.5 billion junk-bond offering. This move highlights the substantial capital being raised through debt markets to finance the rapidly expanding artificial intelligence infrastructure. The planned sale is part of a broader trend where companies are tapping high-yield debt to fund data centers, crucial for AI development and deployment.
This follows several other significant debt issuances related to AI infrastructure. Earlier in June 2026, a data center linked to CoreWeave, Elk Grove Village Property LLC, successfully raised $900 million from a high-yield note offering, with the five-year bonds yielding 7.5%. In the same month, CoreWeave also made headlines by selling €2 billion ($2.3 billion) in euro-denominated junk bonds and an additional $1.25 billion in dollar bonds, yielding 8.5% and 9.625% respectively, marking its global funding expansion. In April 2026, CoreWeave sold $1 billion of 2031 bonds with a 9.75% interest rate, building on an earlier $1.75 billion offering of the same notes.
The demand for AI infrastructure has led to a flurry of debt financing. For instance, Google-backed data centers secured a record $5.7 billion in a junk bond sale in April 2026, as part of a combined $6.7 billion raise that included CoreWeave's $1 billion offering. This surge in debt reflects the massive investment required for data centers, specialized chips, and other infrastructure essential for powering the AI boom. CoreWeave has been actively accumulating significant debt to fund its build-out, including securing an $8.5 billion loan in late March 2026 to support GPU purchases for a Meta contract and $2 billion in investment from Nvidia earlier in the year.
The large sums being raised through junk bonds underscore the high capital intensity of the AI industry. These debt offerings are crucial for companies like CoreWeave, which are at the forefront of providing cloud and computing power for AI, enabling them to expand their capacity and meet the growing demand from AI developers and companies. The willingness of investors to fund these ventures through high-yield debt indicates confidence in the long-term growth prospects of the artificial intelligence sector, despite the inherent risks associated with junk bonds.
