Nebius Group NV (NBIS)

Investing.com -- Nebius Group stock rose 3.7% in morning trading after the company confirmed the successful close of its $5.75 billion convertible senior notes offering, with institutional purchasers exercising their full overallotment options across both tranches — $450 million in additional 2030 notes and $300 million in additional 2034 notes — pushing the final raise well above the original $4.5 billion target. The proceeds are earmarked for data center construction, GPU procurement, and the continued buildout of Nebius's full-stack AI cloud platform.

Today's rebound comes after shares fell sharply on Monday as the settlement date for the offering arrived and investors initially focused on the scale of the company's expanding debt obligations. The additional tailwind came from NVIDIA's announcement that its Groq 3 LPX rack-scale AI inference systems — now in full production following NVIDIA's roughly $20 billion acquisition of Groq assets — will be first deployed at Nebius, cementing the company's role as a flagship partner in NVIDIA's AI infrastructure ecosystem.

The broader market is providing a constructive backdrop, with the S&P 500 adding 0.4% and the NASDAQ up 0.7%, though Nebius is outpacing both indices by a wide margin. The neocloud sector broadly is benefiting from sustained investor appetite for AI infrastructure capacity, and Nebius's year-to-date performance — despite recent volatility — underscores the high sensitivity of the stock to company-specific developments.

Taken together, the combination of a debt raise that exceeded expectations, full institutional participation via the overallotment, and a high-profile NVIDIA partnership announcement has allowed Nebius to shake off Monday's selloff and reclaim momentum in today's session, with shares trading as high as $220.23 intraday.
