Nvidia's Spectrum-6 and Vera CPU Debut at SIGGRAPH as Nebius Stake Generates $1.85 Billion Paper Gain
Published on 07/21/2026 at 21:11 | Redaktion boerse-global.de
Nvidia used the SIGGRAPH conference in Los Angeles to unveil a pair of infrastructure upgrades aimed squarely at the growing market for "agentic AI," while simultaneously disclosing a $1.85 billion paper profit from its strategic stake in cloud operator Nebius Group. The dual announcements underscore the chipmaker's determination to extend its influence beyond GPU sales into the broader ecosystem of AI data centers, even as rival AMD celebrates a key customer win.
The centerpiece of the hardware rollout is Spectrum-6, a new Ethernet networking platform that delivers a switching capacity of 102.4 terabits per second — double that of its predecessor. Designed for the massive scale required to train and run complex AI agents, the system has already lined up Microsoft, CoreWeave and Nebius as early adopters. Nvidia's goal is to supply not just processors but the entire infrastructure stack for agentic workloads, stitching together compute, networking and storage.
Complementing the network push is the Vera CPU, built on the Olympus architecture. The chip packs 88 custom cores and 176 threads through a spatial multithreading design, and supports up to 1.5 terabytes of LPDDR5X memory with 1.2 terabytes per second of bandwidth. Unlike conventional server chips, Vera is tuned for the fast single-thread execution and low-latency GPU communication that AI agents demand. Internal Nvidia benchmarks show significant advantages over x86 rivals in graph processing and reinforcement learning tasks, especially when paired with the Spectrum-6 fabric and Blackwell or Vera-Rubin GPUs.
The timing of the announcements highlights the intensifying competition. Just a day earlier, AMD won Microsoft Azure as the anchor customer for its Helios rack system, which combines AMD Instinct GPUs with EPYC "Venice" processors. Helios offers a direct alternative to Nvidia's proprietary ecosystem, and while Nvidia still dominates data-center GPU market share, the move signals a growing appetite among hyperscalers for multi-vendor supply chains.
Should investors sell immediately? Or is it worth buying Nvidia?
In parallel with the hardware news, Nvidia revealed in a July 13 Schedule 13G filing with the SEC that it holds a 9.3% stake in Nebius Group, representing 22,256,412 Class A shares. The bulk of that position — 21,065,936 shares — comes from a prepaid warrant acquired in March as part of a $2 billion investment in the cloud firm. The warrant was purchased at $94.94 per share but carries a nominal exercise price of just $0.0001, though Nvidia cannot exercise or sell until after September 11, 2026. With Nebius shares recently trading at $182.62, the warrant alone is worth roughly $3.85 billion, yielding an unrealized gain of $1.85 billion over the original outlay.
Nebius, which emerged from the restructuring of Yandex, rents GPU capacity for AI workloads and claims contracted revenue of more than $40 billion with Microsoft and Meta. Meta signed a long-term deal worth up to $27 billion in March, and AI startup Reflection AI added a $1 billion computing agreement. To fund expansion to over 5 gigawatts of capacity by 2030, Nebius secured a $775 million secured credit facility on July 17, maturing in 2030. Analyst reaction was swift: Northland raised its price target to $410, while Freedom Capital Markets upgraded the stock to buy.
The Nebius bet fits into a broader pattern of strategic investments through which Nvidia locks in demand for its hardware. The company contributed $30 billion to OpenAI's $110 billion financing round and participated in Anthropic's $30 billion raise. According to Bloomberg Tax, tech firms are increasingly using variable interest entities to finance multibillion-dollar AI infrastructure off their balance sheets — a practice that has drawn regulatory scrutiny, particularly given that Nvidia itself carries $119 billion in future purchase commitments.
Nvidia at a turning point? This analysis reveals what investors need to know now.
Back at its own shares, Nvidia stock rose 1.58% on Tuesday to €180.92 in German trading, still about 10.6% below the 52-week high of €202.50 set in mid-May. Analysts at Simply Wall St peg the fair value of the stock at $236 using a discounted cash flow model, implying roughly 14% upside, and note that the trailing P/E of 30.8 is well below the industry average of 57.6, supported by free cash flow of $119.4 billion over the past twelve months. For now, the Nebius stake adds a multibillion-dollar paper gain and reinforces Nvidia's cloud ambitions, but the market appears to be waiting for more tangible signs that the company's infrastructure strategy will translate into sustained share-price momentum.
