Nvidia shares dip 0.77% to $213.73 as Vera CPUs join Oracle's AI expansion

Nvidia shares fell 0.77% to $213.73 at 10:20 ET on October 29, as Oracle announced a wider rollout of Nvidia hardware. Oracle and Nvidia said Vera Rubin NVL72 systems and Vera CPUs are now generally available on Oracle Cloud Infrastructure. They also plan to expand capacity to multiple gigawatts. Each NVL72 rack links 72 GPUs. Smaller eight-GPU Rubin HGX NVL8 systems remain planned. Vera CPUs handle tasks such as running code, calling tools, and retrieving data, work that can leave costly GPUs idle. The move gives Nvidia another way to earn from AI workloads. No purchase value was disclosed. Nvidia has a market capitalisation of $5.15 trillion and a price-to-earnings ratio of 27.02.

Oracle to bill per AI task as it eyes $225B revenue by 2030 and $90B+ capex

Oracle plans to charge customers for AI work done in its applications, on top of subscriptions. Chris Leone, executive vice president of application development, told investors on Wednesday that more AI use means more revenue without adding seats. The plan builds on Fusion Claw, a runtime unveiled this month to help customers control AI agents in finance, supply chain, and ERP software on Oracle Cloud Infrastructure (OCI). Oracle spent $55.7 billion on datacentres and cloud infrastructure in fiscal 2026 and plans to spend $90 billion to $95 billion in fiscal 2027. It hopes to raise about $40 billion in debt and equity in 2027, after raising $18 billion in debt in September 2025. Oracle expects fiscal 2030 revenue of $225 billion, a 35% compound annual growth rate from 2026, and positive cash flow by the second half of fiscal 2028.

Oracle targets $30B free cash flow by fiscal 2029, sending shares up 11%

Oracle expects to generate $30 billion in free cash flow by the fiscal year ending May 2029, chief financial officer Hilary Maxson said at its investor day in Las Vegas. The forecast beat Wall Street expectations, which had pointed to deeply negative cash flow. Oracle shares rose about 11%, their best day since May. The company expects to return to positive cash flow by late fiscal 2028. It will cap additional funding through fiscal 2030 at $20 billion, split evenly between equity and debt. Oracle also reaffirmed a target of $225 billion in revenue by fiscal 2030. It plans to add seven gigawatts of data centre capacity over the next couple of years, taking its total beyond 10 gigawatts by the end of fiscal 2028. Cash flow was negative $23.7 billion in the year to May 2026. The stock is still down about 26% this year.

Oracle shares jump 4% as OCI adds Nvidia, Google, Intel and Cerebras chips

Oracle shares rose about 4% on Tuesday after the company announced chip partnerships to expand AI capabilities on Oracle Cloud Infrastructure (OCI) ahead of its Investor Day. The deals involve Cerebras, Intel, Nvidia, and Google. Oracle plans to offer Cerebras Inference on OCI from 2027, aimed at faster inference for complex AI agents. It also signed a multiyear agreement to deploy Intel Xeon processors across OCI, including planned X14 offerings built on Intel's Diamond Rapids chips. OCI will build multi-gigawatt Superclusters using Nvidia Vera Rubin NVL72 systems. It will also be the first hyperscaler outside Google to offer Google's Tensor Processing Units, with TPU 8t for training and TPU 8i for inference expected from 2027.

Oracle stock down 54% in a year, but analysts see 84% upside to $240 on $664B backlog

Oracle shares have fallen 54% over the past year, largely on concern about the debt it has taken on to build artificial intelligence (AI) data centres. Wall Street expects a rebound. The median 12-month analyst price target of $240 implies an 84% gain from current levels. Of 45 analysts, 36 rate the stock a buy. Oracle reported a $664 billion backlog in the first quarter of fiscal 2027. Cloud infrastructure revenue rose 121%, up from 93% growth in the prior quarter. The company expects fiscal 2027 revenue to rise 34% to at least $90 billion. Analysts forecast 46% growth to $131.8 billion in fiscal 2028. Oracle trades at 5 times sales, below its five-year average of 6.6.
