US tech giant Nvidia will invest up to $100bn (£73bn) in OpenAI, the firm behind ChatGPT, the companies have announced.

Nvidia said it will supply high-performance chips needed for the processing power required by artificial intelligence (AI), of which OpenAI is a specialist.

Described as a “strategic partnership” by Nvidia, it is the latest move by two high profile tech firms in the global AI race, where China is an emerging rival.

The announcement comes after a series of high-profile investments by Nvidia, including a $5bn investment in Intel and a £2bn investment in the UK’s AI sector.

Nvidia, which is the world’s most valuable company, said its latest investment will go towards data centres for OpenAI’s “next-generation AI infrastructure”.

Jensen Huang, chief executive of Nvidia, said the funding will mark the “next leap forward and power the next era of intelligence”.

Both firms said they were already working with a broad network of collaborators focused on making the “world’s most advanced AI infrastructure”, including working with Microsoft, Oracle, SoftBank, and Stargate.

However, the dominance of US AI firms has come under threat from China – particularly with the rise of DeepSeek-R1.

Meanwhile, Nvidia has come under pressure from both the Chinese and the US governments.

China said last week Nvidia had violated its anti-monopoly laws, but did not give details of how Nvidia had breached the rules.

China also reportedly ordered its top technology companies to halt purchases of the firm’s artificial intelligence (AI) chips. Huang told the BBC at the time he was “disappointed” with the news.

It came after Nvidia and its rival AMD agreed to pay the US government 15% of Chinese revenues to secure export licences to China to undo a US government ban on AI chip sales to the country.

Nvidia’s share price closed up 4% at the end of Monday’s trading in the US.

OpenAI said it had more than 700 million weekly active users, and that its new partnership with Nvidia would “advance its mission to build artificial general intelligence that benefits all of humanity.”

It added that the details would be finalised in the coming weeks.

Sam Altman, cofounder and chief executive of OpenAI, said the partnership meant both firms would work together to “create new AI breakthroughs and empower people and businesses with them at scale”.

Greg Brockman, cofounder and president of OpenAI, said the company had been working closely with Nvidia since “the early days” of the business.

All remaining Bodycare shops will shut this week, after the beauty chain’s administrators failed to secure a buyer to keep it on Britain’s high streets.

The chain is set to vanish from Britain’s high streets, with administrators confirming the closure of all 56 remaining stores, leading to approximately 450 redundancies. The beauty retailer entered administration earlier this month, failing to secure a buyer for its UK chain.

Advisory firm Interpath, overseeing the administration, stated that this inability to find a purchaser necessitated the difficult decision to cease trading. Bodycare, established in Lancashire in 1970, specialised in beauty products, fragrances, and various bathroom essentials.

Its outlets were a familiar sight in shopping centres and high streets nationwide. The final closures are anticipated by Saturday, affecting all 444 employees across the stores, who will now face redundancy.

The exchange announced that the pre-opening session will take place from 1:30 pm to 1.45 pm

The market will remain closed for regular trading on Diwali, but a special trading window will be open for one hour.

Stock exchanges NSE and BSE will conduct a special Muhurat trading session on Tuesday, October 21, to mark the festival of Diwali, the bourses announced on Monday.

The symbolic trading session will be held between 1:45 pm and 2:45 pm, the stock exchanges said in separate circulars.

Last year, the special Muhurat trading session was held from 6 pm to 7 pm.

The new session also marks the beginning of a new Samvat (Vikram Samvat 2082) — the Hindu calendar year that starts on Diwali — and it is believed that trading during the ‘Muhurat’ or auspicious hour brings prosperity and financial growth for the stakeholders.

The market will remain closed for regular trading on Diwali, but a special trading window will be open for one hour.

The exchange announced that the pre-opening session will take place from 1:30 pm to 1.45 pm.

Market analysts noted that Diwali is considered an auspicious occasion to begin new ventures, and many investors believe participating in the Muhurat trading session brings prosperity throughout the year.

However, with the trading window limited to just an hour, the markets often witness heightened volatility. Analysts added that the significance of the session lies more in its symbolic value than in immediate profitability.

Trading would take place across various segments like equity, commodity derivatives, currency derivatives, equity futures & options, and securities lending & borrowing (SLB) in the same time slot, according to separate circulars issued by the bourses. PTI SP SHW
