Nvidia/Open AI

As usual, NVIDIA Corp (NASDAQ:NVDA) continues to be a popular single stock among ii customers this week, landing in sixth position in our most-bought list, unchanged versus last week.

The chipmaker, which rarely fails to make headlines, this week said that it had agreed a deal with OpenAI to guarantee up to $105 billion (£77 billion) to support a 20-year lease for its upcoming giant data centre in Ohio, supported by infrastructure developer and operator SB Energy, which controls the physical site.  Nvidia is also investing $1.5 billion in SB Energy directly, owned by SoftBank.

Nvidia’s CEO Jensen Huang has responded to criticism that the deal is another example of circular financing in the AI infrastructure build-out. Critics argue that Nvidia supports infrastructure financing for OpenAI, which is a major Nvidia customer, creating a feedback loop.  

Google/Marvell

Alphabet Inc Class A (NASDAQ:GOOGL) and Marvell Technology Inc (NASDAQ:MRVL) are both among the most-bought tech stocks on the ii platform so far this week. Google and Marvell have announced plans to work more closely together in the development of specialised AI chips, Tensor Processing Units (TPUs). In exchange for developing custom chips for Google, Marvell has given the hyperscaler the option to become its fifth-largest investor through the right to buy a possible stake worth $12.2 billion.

Shares in Marvell surged on the news, while Broadcom Inc (NASDAQ:AVGO), which already makes custom TPUs for Google, fell sharply.

Google and other hyperscalers have increasingly been trying to use chip parters to develop and control their own custom chip designs, rather than depending on Nvidia’s expensive graphics processing units (GPUs).

Other news

Unitree

Unitree Robotics enjoyed a standing ovation from investors in its stock market debut on Wednesday in Shanghai. 

Shares soared more than 600% to the intraday peak, closing the first session up by around 460%, moving from an IPO price of RMB 150.8 per share to a close of RMP 845. Shares only gave back a relatively small percentage of those gains (~11%) on their second day of trade. 

The robotics unicorn, worth around $50 billion, has come to symbolise China’s technology prowess. Unitree has two main product categories within physical AI – humanoid robots and robotic dogs – and aims to develop more affordable, mass market, commercial robotic products. 

Wang Xingxing, Unitree’s CEO, believes robots are moving towards a “ChatGPT moment”, adding, “We hope that in the future, we can see a robot be introduced into an unfamiliar household and it can achieve approximately 80% of tasks successfully through voice or text commands.”

Week Ahead

Nvidia

Nvidia takes centre stage in terms of the week ahead with its fiscal 2027 second-quarter earnings report after the market close on Wednesday. There is a high bar going into these earnings – shares have fallen after its most recent four quarterly earnings reports despite very impressive numbers. The company is looking to evolve from a pure AI chip supplier into a full-stack AI factory architect.

The company at the heart of the AI infrastructure roll-out is expected to report revenue around $91 billion and earnings per share of $2.09. Investors will be paying close attention to its critical data-centre revenue figure as well as its Q3 guidance for clues into its outlook. The performance of Blackwell Ultra and any indications about Vera Rubin will be in focus as well as any comments around its recent AI infrastructure financing deals. Possible sales in China could be the wildcard this quarter, not factored into its guidance after it started shipping powerful H200 AI chips to China, although this is expected to be quite small.

Last quarter Nvidia reported sales of $81.62 billion up 85% year-on-year and adjusted earning per share of $1.87, both beating expectations. Over 90% of sales came from data-centre revenue, which soared to $75.2 billion, $38 billion of which came from the hyperscalers. It announced a new way of reporting its earnings in two segments – data centres and edge computing. Nvidia also returned more cash to shareholders through an $80 billion share buyback programme and upped its dividend to 25 cents per share.

Shares in Nvidia are up around 16%, outperforming the Nasdaq and S&P 500 but underperforming some of the 2026 standout semiconductor winners like Micron Technology Inc (NASDAQ:MU), which is up over 200%.

Although it has participated in less of this year’s upside, it has also been more resilient to the recent AI market volatility, as investors view Nvidia as the quality player in the semiconductor sector, underpinned by high margins and a strong track record.
