Nvidia is doubling down on the infrastructure needed to train and run physical AI, rolling out open-source simulation libraries on the same day it disclosed a 9.3 percent stake in cloud provider Nebius Group. The twin announcements, both made on July 20, 2026, underscore a strategy that spans from foundational software for autonomous robots to equity-backed compute capacity for the AI cloud.
At the heart of the software push are three new modules for Nvidia’s Omniverse platform: ovrtx for RTX sensor simulation, ovphysx for GPU-accelerated physics, and CAD-to-SimReady, which automatically converts engineering designs into simulation-ready formats. All are available on GitHub. Companies like SideFX, PTC, and a handful of startups including ForgeCAD and Moonlake AI have already integrated them. The libraries are designed to run on Nvidia’s upcoming RTX Spark hardware, due this autumn from partners such as ASUS, Dell, HP, Lenovo and MSI, as well as on the already-orderable DGX Station. CEO Jensen Huang framed the moment succinctly, stating that the era of physical AI will first be built in simulation.
The day after, on July 21, Nvidia added Cosmos 3 Edge — a world model with four billion parameters tailored to run directly on robotics hardware. Operating at 15 Hertz on the Jetson Thor chip, the model has been fine-tuned on the DROID dataset and is also freely available on GitHub. Developers can use it to compute autonomous robot actions on-device, bypassing cloud dependency.
Alongside the software push, Nvidia’s investment in Nebius signals a more direct bet on cloud infrastructure. A Schedule 13G filing with the SEC reveals Nvidia holds 22,256,412 shares in the company, of which roughly 1.19 million are common stock and the remaining 21.07 million are warrants. Those warrants stem from a $2 billion investment in Nebius announced on March 11, 2026, and cannot be exercised before September 11, 2026. Nvidia has classified the position as passive, with no intention of taking control. Nebius shares gained 2.76 percent in regular trading to $182.62 and jumped as much as 4 percent after hours, helped also by a $775 million credit facility backed by GPU capacity for a large client and a computing services deal with Reflection AI valued at over $1 billion. Analysts responded swiftly: Northland raised its price target from $248 to $410 with an Outperform rating, while Freedom Capital initiated coverage at Buy with a $200 target.
Should investors sell immediately? Or is it worth buying Nvidia?
The industrial application of Nvidia’s simulation strategy is already taking concrete shape. SKAI Intelligence, together with ABB Robotics, has published a whitepaper on physical AI for high-precision manufacturing, with contributions from AsiaInfo and Deloitte. The workflow, dubbed Real2Sim2Real, combines digital twins with synthetic data. At the World Artificial Intelligence Conference in Shanghai, SKAI also presented a Chinese-language version and formalised a strategic partnership with ABB focused on machine vision and synthetic training data. In another vertical, Bristol Myers Squibb has purchased a DGX SuperPOD based on Nvidia’s new Vera-Rubin architecture to accelerate drug discovery, reporting that AI tools are already shortening development timelines by 20 to 30 percent and could eventually deliver up to 50 percent. Nvidia says the Vera-Rubin platform offers ten times the performance per watt of its predecessors.
On the stock market, the reaction has been muted despite the flurry of news. Nvidia shares closed at €178.10 on Monday, down nearly 4 percent on the week, though they edged up 1 percent to €179.94 on the day of the announcements. That leaves the stock roughly 11.14 percent below its 52-week high of €202.50 reached on May 14, 2026, and just under 2 percent below its 50-day moving average. The fundamentals remain sturdy — revenue growth of 70.7 percent year-over-year, an operating margin of 64.02 percent, and a free cash flow margin of 46.97 percent. At a price-to-earnings ratio of 30.8 and a PEG ratio of 0.28, the valuation still looks reasonable relative to growth. The next quarterly report is due on August 26.
Wall Street remains broadly bullish: KeyBanc recently reiterated an Overweight rating with a $330 target, and the consensus among analysts stands at $304.26 to $309.94, with 36 buy ratings versus a single hold. Yet a contrarian note comes from investor David Desjardins, who has assigned a “Strong Sell” rating, citing physical constraints. With a market capitalisation of roughly $5 trillion, Nvidia already accounts for about 7 percent of the S&P 500, and Goldman Sachs projects US data centre power consumption will more than double from 31 gigawatts in 2025 to 66 gigawatts by 2027, consuming 8.5 percent of peak grid capacity. Desjardins argues that such an energy bottleneck could cap Nvidia’s expansion. For now, the market appears to be weighing the company’s technological lead in simulation and robotics AI against the very real limits of infrastructure scale.
