"It’s a big win for the company which has been trying to expand its customer base around the world," said Susannah Streeter, head of money and markets at Hargreaves Lansdown.
In addition, Bloomberg reported on Tuesday that the Trump administration was considering a deal that would allow the United Arab Emirates (UAE) to import "more than a million" advanced Nvidia chips.
Spokespeople for the White House and Nvidia did not immediately respond to Yahoo Finance UK's request for comment.
The jump in shares came after Monday's gains on the back of news that the US and China had agreed to cut tariffs on each other's imports by 115% for 90 days, marking a de-escalation in trade tensions.
Shares in server maker Super Micro Computer (SMCI) soared 16% on Tuesday and were up nearly 8% in pre-market trading on Wednesday, thanks to a strong analyst rating.
Raymond James (RJF) analysts initiated coverage of the stock, giving it an outperform rating and setting a price target of $41 (£30.72).
Shares in Super Micro had fallen recently after the company lowered its full-year revenue outlook, citing economic uncertainty and Trump's trade war, as well as competition from other AI server makers.
Super Micro said it expected full-year revenue for 2025 to fall to between $21.8bn and $22.6bn, down from its prior guidance of $23.5bn and $25bn.
Another tech name on the rise on Tuesday was Palantir (PLTR), which closed the session 8% in the green, with shares hitting a fresh high.
Archer Aviation (ACHR), which develops electrical vertical take-off and landing vehicles, announced a partnership with Palantir in its quarterly results on Tuesday.
The company said that their plans included the "development of next-gen software utilising AI to improve a range of aviation systems."
The company said first quarter revenue in its international commercial segment, which sells software to businesses abroad, fell 5% compared to the previous year due to "headwinds" in Europe. Revenue for this area of the business came in at $142m, which was below the $160m expected by analysts.
However, Palantir's revenue for the quarter, of $884m, was ahead of estimates of $863m and earnings per share of $0.13 were in line with forecasts, according to Bloomberg data.
In Europe, shares in Tui (TUI1.DE) slid 10.5%, after the German travel operator flagged a slight slowdown in summer bookings.
Tui said that while summer 2025 bookings were "robust", they were "slightly down at -1%, based on flat risk capacity in a competitive environment with our focus on growing dynamically, protecting margin and reducing cost."
The company posted a 1.5% increase in revenue for the second quarter to €3.7bn (£3.11bn). Underlying operating losses increased by €18m to €207m, though Hargreaves Lansdown equity analyst Aarin Chiekrie pointed out that this was better than an expected loss of €224m.
Chiekrie, who holds shares in Tui, said: "Operating in a sector that is at the mercy of consumer sentiment and spending power can be difficult. The current challenging economic backdrop makes it hard to map the demand picture accurately.
"Some signs of softness in Germany are something to keep an eye on, and investors will be keen to see the print here pick up in the second half. But all in all, Tui looks to be navigating these challenges well."
On the London market, shares in luxury fashion house Burberry (BRBY.L) popped 8% after the company shared plans to cut costs in order to help it return to profit.
Burberry said it planned to cut a potential 1,700 jobs worldwide, representing about 20% of its workforce. It also raised its cost cutting target to £100m ($133m) of savings annually by the 2027 financial year.
In its preliminary results, published on Wednesday, Burberry posted a reported operating loss of £3m for the year, which was down from a reported operating profit of £418m last year.
Russ Mould, investment director at AJ Bell (AJB.L), said: "Despite its results being slightly less bad than feared, Burberry is not showing any complacency, with the luxury goods firm announcing some pretty radical steps in its continuing recovery effort.
“Having enjoyed a strong run going into these numbers as relations between two of its key markets – the US and China – seemed to thaw, the momentum has continued as investors reacted positively to the news."
