Nvidia Faces a Dual Test as Rubin Timeline Uncertainty Meets Hyperscaler Chip Ambitions
Published on 07/14/2026 at 09:31 | Redaktion boerse-global.de
Investors in Nvidia are juggling two narratives at once: the possibility of a delay in the next-generation Rubin architecture, and a growing push by major cloud customers to develop their own artificial intelligence processors. Neither story is new, but their convergence is testing the conviction behind the stock’s lofty valuation.
The shares closed Monday at €178.80 before ticking up to €180.30 in the following session, a gain of 0.82% on the day that brings the year-to-date advance to 28.22%. That still leaves the stock nearly 11% below its 52-week high of €202.50 reached in May 2026, and about 1.4% under the 50-day moving average of €181.65. The 14-day relative strength index sits at 53.2, a neutral reading that leaves little clue about the next directional move.
The Rubin Question and a Critical Revenue Forecast
Unconfirmed market chatter has cast doubt on the delivery timeline for Rubin, the chip architecture that follows the current Blackwell series. Nvidia officially maintains that its product roadmap is intact, but the whispers have persisted since early July. The timing is particularly delicate because the company recently issued a second-quarter fiscal 2027 revenue forecast of €91 billion, underpinned by record growth in data center and networking revenue.
The bullish case rests on the idea that Nvidia’s transformation from a graphics-chip supplier to a full-stack AI infrastructure provider insulates it from any single product slip. Networking revenue — including Spectrum-X Ethernet and InfiniBand — surged 199% to €14.8 billion in the latest reported quarter, nearly three times the growth rate of the core compute business. Sovereign AI, government-funded infrastructure projects, has grown into a €30 billion market in fiscal 2026. Analysts at large see these diversifying revenue streams as shock absorbers, reflected in a consensus price target of €264.24 that implies 46.6% upside from Monday’s close.
Should investors sell immediately? Or is it worth buying Nvidia?
Yet execution risks are real. Reports suggest the "Kyber" rack for the NVL144 series may not ship until 2028, delayed by manufacturing issues with the PCB interposer. Should Rubin run into trouble with HBM4 memory validation or demanding liquid-cooling requirements, Nvidia could face a gap that rivals would exploit. Customer concentration adds another layer: historically, more than 60% of total revenue comes from just four hyperscale cloud operators, and any one of them leaning more heavily on in-house silicon would hit Nvidia disproportionately, given the stock’s annualized volatility of 36.34%.
Google and Meta Push Their Own Silicon
That hypothetical risk is becoming concrete. Google is actively expanding sales of its custom TPU chips beyond its own cloud platform, targeting independent cloud providers known as Neoclouds. The first high-profile target is Nscale, a two-year-old provider that counts Nvidia itself as a major investor. Google’s pitch: TPUs offer more stable performance and simpler server networking than GPU-based systems, pointing specifically to integration delays that some customers have encountered with Nvidia’s Grace-Blackwell and the upcoming Vera-Rubin platforms.
Separately, Meta plans to begin production of its own chip, code-named "Iris," in September, with the goal of doubling compute capacity and reducing reliance on Nvidia and AMD. The combined pressure from two of the "Big Four" hyperscalers has sent a ripple through the market — Nvidia lost roughly $1 trillion in market capitalization from its May 14 peak before a sharp bounce last Friday, when the stock surged 4% to lead the Dow.
Wall Street’s Muted Alarm
Analysts have so far declined to sound the alarm. Daniel Newman of Futurum Group argues that Meta’s chip effort complements rather than replaces Nvidia, addressing capacity constraints rather than challenging the incumbent’s core position. Mizuho’s Vijay Rakesh echoes the view, noting that while a Google-Meta TPU deal would benefit Broadcom as the manufacturer, Nvidia remains "still the king" for AI model training.
Nvidia at a turning point? This analysis reveals what investors need to know now.
Citi’s Atif Malik sees the current valuation as a buying opportunity, pointing out that Nvidia intends to return half of its cash flow to shareholders this year. Bank of America reaffirmed its "Top Pick" rating, citing Nvidia’s strong access to DRAM memory in a tight supply environment. The 200-day moving average of €164.98 remains a key technical floor; as long as the stock holds above that level, the long-term uptrend is intact.
The next major catalyst will be the earnings call for the second quarter of fiscal 2027. If management confirms the €91 billion revenue guide and shows Rubin production progressing on schedule, the stock could make another run at the €202.50 high. If it signals delays or reveals that networking growth cannot fully offset a maturing Blackwell cycle, a retest of the 200-day average becomes the most likely path. Competition from hyperscaler homegrown chips will not disappear overnight, but for now most on Wall Street see it as a market-expansion story rather than an existential threat.
