Shares in chipmaker Nvidia (NVDA) are on track to reach a new record high, as the stock climbed 3% to hit $139.26 in early trading in the US on Monday.

The stock is up 181% year-to-date and previously hit a record high closing price of $135.58 in June.

This latest rise has given it a market valuation of $3.4tn (£2.6tn) and make it poised to unseat Apple (AAPL), which has a market cap of nearly $3.5tn, as the world's most valuable company.

Nvidia shares have been fuelled by barrage of good news around the company, including Wall Street analysts reiterating their buy ratings on the stock last week.

Meanwhile, electronics manufacturing group Foxconn announced that it was building a huge facility in Mexico to produce Nvidia's GB200 superchips. The two companies also said that they are building Taiwan's largest supercomputer.

Nvidia CEO Jensen Huang said in a recent interview that demand for the company's Blackwell AI chips is "insane".

Eric Schmidt, former CEO of Google (GOOG), warned prime minister Keir Starmer that not fixing UK regulation may risk the government not meeting its 2030 clean energy goal.

Schmidt said on stage with Starmer at the UK's investment conference that "democracies — especially something as ... old as this one have so many ways in which people can say no".

"I'd much rather have a single person who can say yes or no, and who says no, and then [companies] can move on," he said.

"The cost of capital, and the delay, is killing you. And further more you're not going to achieve your 2030 energy goal ... without fixing this," Schmidt added.

"Today’s drumbeat of investment is a vote of confidence in Britain and our approach to work with business to deliver sustained growth for all."

Logistics giant DP World announced a £1bn investment to expand its London Gateway port as the UK's International Investment summit kicked off on Monday.

The Dubai-based company said it would increase capacity at the port by building two new shipping berths, as well as adding a second rail terminal to handle an expected increase in in containerised trade.

DP World said the expansion would create a further 400 permanent new jobs, in addition to the 1,200 currently employed at the site.

The announcement comes after a row involving UK transport secretary Louise Haigh last week in which she criticised its P&O Ferries division when announcing new worker protections.

Haigh had called P&O a "rogue operator" in an interview with ITV News and encouraged consumers to boycott the company. Haigh's comments came two years after P&O laid off nearly 800 British seafarers and replaced them with lower-paid overseas staff.

Following Haigh's comments, it was reported that DP World had put its announcement of further investment in the London Gateway port on hold.

However, prime minister Keir Starmer said on the BBC's Newscast podcast said the comments were "not the view of the government".

Executives from some of the world's biggest investment firms have said that they are "optimistic" about Britain's prospects, in a letter published by The Times ahead of today's International Investment Summit in London.

Goldman Sachs (GS) CEO David Solomon, Bank of America (BAC) president of international Bernard Mensah, JPMorgan (JPM) global banking co-head Filippo Gori, Legal & General (LGEN.L) CEO António Simões and Aviva (AV.L) CEO Amanda Blanc were among those signatories on the letter.

"As global investors, we believe that there is a very real opportunity for the UK to grow its economy by attracting international investment," the letter said.

"Britain’s educational establishments, legal system, financial services sector and language form the bedrock of a strong investment proposition. Technological developments, advances in the energy system and greater freedom in capital flows have further enhanced Britain’s position.

"With greater stability, its attractiveness is increased even further. We are optimistic about the future of the economy, and believe it is time to invest in Britain."

Oil prices dropped on Monday, reacting to disappointing economic data from China, the world’s largest crude importer, which revealed a persistent deflationary trend. The country’s plans for fiscal stimulus also failed to meet market expectations, further weighing on prices.

Brent crude futures (BZ=F) lost 2.2%% to $77.31 a barrel, while US West Texas Intermediate (CL=F) crude retreated 2.2% to $73.87 per barrel during early European trading.

Crude markets were additionally affected by ongoing discussions about a potential ceasefire in the Middle East. Rising tensions in the region had previously propelled oil prices upward for two consecutive weeks, but speculation of a de-escalation has shifted sentiment.
