Tokyo stocks rise in morning on further AI development hopes

Tokyo stocks experienced a morning increase on Wednesday, propelled by artificial intelligence and semiconductor-related shares in anticipation of further expansion in AI-driven businesses. The 225-stock Nikkei Stock Average surged 837.54 points, or 1.28%, to 66,318.81 from Tuesday's closing figure. The Topix index, representing a broader market, climbed 34.91 points, or 0.86%, to 4,076.04.

The U.S. dollar experienced a temporary dip, touching the lower 156 yen level, as domestic exporters' demand for yen surged, albeit with caution over potential currency interventions following recent statements by Japanese authorities. By noon, the dollar traded at 156.68-70 yen, contrasting with the New York rates of 157.23-33 yen and 157.37-39 yen in Tokyo.

The euro was valued between $1.1339-1340 and 178.61-65 yen, compared to the earlier New York rates of $1.1335-1345 and 178.32-42 yen. Softbank Group's shares led the gains following reports that OpenAI's annualized revenue based on present performance was nearing $70 billion, indicating a rapid growth trajectory from $40 billion in a separate report published in August.

Investor confidence was further bolstered by TDK Corp. and Taiyo Yuden Co.'s announcement, made after the closing bell on Tuesday, of preliminary talks to form a business alliance for the joint development of electronic components, spurred by robust demand stemming from the burgeoning AI data centers industry.
