Nvidia's Bull Case Runs Into a Working-Capital Wall
Published on 10/23/2026 at 08:11 | Editorial boerse-global.de
Citigroup reaffirmed its buy rating on Nvidia with a 315 US-dollar price target, and BNP Paribas kept its Outperform call at 345 US-dollar — yet neither endorsement stopped the stock from sliding 4.2% yesterday. The split screen captures the central tension in the Nvidia story right now: demand is not the problem, but the money and machinery needed to turn that demand into running data centers very much are.
The two brokerages both point to constraints on the supply and execution side rather than any cooling of interest in AI compute. Citigroup said the Berlin GTC improved visibility on volume production of the Vera Rubin line for 2027–2028. BNP Paribas analyst Karl Ackerman, for his part, sees Nvidia's optical networking roadmap on track, with horizontal scale-out optical connections still expected in the second half of 2026 and vertical scaling in the second half of 2027. Those dates are expectations about delivery, not completed build-outs.
A Selloff Rooted in the Sector, Not the Company
The retreat was part of a broad re-rating of AI stocks rather than a reaction to any single Nvidia announcement. AP tied the pullback to fresh doubts about the scale of AI spending, compounded by worries over how data centers and AI chips will be financed. Reuters reported that comments from CEO Jensen Huang during his CNBC interview at the Berlin GTC fed the selling: he described demand from specialized cloud providers as extraordinarily strong while flagging a shortage of working capital.
That admission cuts to the heart of the bull case. Buyers have to be able to pay for the build-out, and appetite alone does not guarantee that compute capacity appears on schedule. SpaceX illustrated both the scale and the gap yesterday, saying it aims to bring 200,000 Nvidia chips online every month. The Financial Times reported that SpaceX is seeking roughly 40 billion US dollars in loans and investment-grade debt to fund the purchases, with Apollo expected to lead the financing and GPUs potentially serving as collateral. According to Bloomberg, those talks are at an early stage and could yet fall apart.
Should investors sell immediately? Or is it worth buying Nvidia?
From Announcements to Live Networks
What separates a credible order pipeline from a press release is the shift from partnership to actual use — and Nvidia offered a tangible data point on that front on Wednesday. T-Mobile completed what the company described as the world's first AI-RAN call on a live network, part of telecom projects and trials with Nokia and operators including Deutsche Telekom, Elisa and BT. It is a genuine deployment step, though a single successful call is a long way from a nationwide rollout.
The same yardstick applies elsewhere. Volvo Cars is adopting Nvidia's Hyperion and Alpamayo stacks for automated driving, and Bolt has chosen Alpamayo for its European robotaxi program. Nvidia also unveiled healthcare and life-sciences work, including an open protein-design model developed with the Institute for Protein Design at the University of Washington and adaptive radiotherapy research with Siemens Healthineers. The breadth is encouraging; how deeply each partner embeds the technology in its own products is what will ultimately matter.
Not every project sits at the same stage. Bolt's data collection in Madrid is slated for 2027 and remains subject to regulatory approval — a step within the robotaxi program, not proof of full operation. Choosing a technology, testing it and running it at scale are distinct milestones.
Nvidia at a turning point? This analysis reveals what investors need to know now.
What Investors Should Watch
The constructive reading holds as long as partners keep advancing their projects and trials graduate into deployments across telecom, automotive and medical applications. Should customer investment appetite or financing capacity falter, the market will likely judge announcements ever more strictly against delivery. Beyond further progress on the telecom work, Bolt's 2027 Madrid data collection stands out as a concrete checkpoint. Citigroup and BNP Paribas are betting on demand and technical execution; the share price decline shows the market still wants proof that the potential can be financed and converted into infrastructure that actually runs.
