South Korean technology giant Samsung Electronics says it expects to post a 19-fold jump in its profits, driven by global demand for artificial intelligence (AI) memory chips.

The company forecast that it would make 89.4tn won (£43.6bn; $58.4bn) between the start of April and the end of June, marking its third consecutive record quarterly operating profit.

Major South Korean firms like Samsung release earnings forecasts ahead of official detailed reports to help guide investors.

Samsung's latest forecast, released on Tuesday ahead of its full results due later in July, comes as demand for semiconductors continues to outstrip supplies - which has pushed up prices.

Samsung said in its earnings preview that it generated around 171tn won in sales during the quarter, more than double the amount for the same period last year.

The company's projected earnings mark one of "the best quarterly performances ever", which was close to the tech sector record set by Nvidia earlier this year, said industry analyst Marc Einstein from Counterpoint Research.

"This has everything to do with the AI boom as memory companies continue to ride a tidal wave driven by limited supply and unprecedented demand," he added.

Samsung has hiked the prices of its memory chips as supplies remain tight.

Research firm IDC said demand for semiconductors for data centres and other AI infrastructure has been "different from anything the memory industry has navigated", impacting the supply of chips for everyday electronics.

"We do expect supplies to be tight through next year given the unabated demand from AI data centres," said tech devices researcher Bryan Ma from IDC.

Samsung is one of the world's biggest semiconductor manufacturers, making chips for firms like Nvidia and Google along with its range of electronic devices. The shares major tech firms have soared in recent months due to surging demand for chips.

Samsung's shares fell by around 5.5% in Seoul on Tuesday morning.

Its stock market value has more than doubled since the start of this year, while South Korean rival SK Hynix has jumped by more than 200%.

The strong performance of both companies has helped lift the value of South Korea's benchmark share index, the Kospi, by more than 80% this year.

In May, Nvidia posted record quarterly sales and profits, with revenue between January and March topping $80bn.

But Nvidia's stock fell at the time, in what some analysts said was a sign that investors were increasingly worried about rising competition in the sector.

In June, South Korea unveiled plans for at least $880bn in investments in projects led by Samsung and SK Hynix to expand the country's chip manufacturing in the coming years.

Rival Asian firms in Japan, China and Taiwan are also investing heavily in chip factories to meet soaring demand.
