Sharecast - The FTSE 100 was called to open 24 points higher at 7,344.
CMC Markets analyst Michael Hewson said: "Back in Q1 when Nvidia set out its revenue guidance for Q2 there was astonishment at the extent of the upgrade to $11bn. This was a huge increase on its Q2 numbers of previous years, or any other quarter, with the upgrade being driven by expectations of a big increase in sales of data centre chips, along with investments in Artificial Intelligence.
"Last night Nvidia crushed these estimates with revenues of $13.5bn, datacentre revenue alone accounting for $10.3bn of that total, a 171% increase from a year ago. For comparison, in Q1 datacentre revenue accounted for $4.3bn.
"Gross margins also beat expectations, coming in at 71.2% as profits crushed forecasts at $2.70 a share. Nvidia went on to project Q3 revenues of $16bn, plus or minus 2%.
"The company also approved an extra $25bn in share buybacks, with the shares soaring above this week’s record highs in after-hours trading, with the big test being whether we’ll see those gains sustained when US markets reopen later today.
"On the back of last night's positive finish, as well as the exuberance generated by the belief that interest rate hike pauses are coming next month, European markets look set to open higher later this morning."

Recruitment firm Hays (LON:HAYS) raised its full-year dividend and announced a £36m special payout to shareholders despite reporting a drop in annual profits.
Operating profit was down 6% at £197m, as a record performance in Germany was outweighed by tough markets in the UK and Ireland, Australia and New Zealand.
Nevertheless, the company saw cash generated by operations rise 9% to £199.3m, allowed it to up its final dividend by 5% to 3p a share and announce a further 2.24p return.
