Nicolai Tangen, CEO of Norway's$1.4tn sovereign wealth fund, has urged governments to accelerate the regulation of artificial intelligence (AI). In an interview with the Financial Times, Tangen said the fund would reveal ethical guidelines in August on how companies it invests in should use AI. The fund, which owns 1.5% of all globally listed shares, is a major investor in tech firms such as Apple, Alphabet, Nvidia and Microsoft, all of which plan to use AI to transform their businesses. Norges Bank, the central bank of Norway, holds stakes in over 9,200 companies worldwide through the wealth fund, which operates under ethical guidelines set by the parliament. The fund excludes investment in firms that do not meet these guidelines. Tangen also told the FT that the fund may consider using AI to assist with proxy voting on tens of thousands of motions at shareholder meetings in the future.
