SoftBank overtakes Toyota as Tokyo's most valuable company on AI surge

SoftBank, the Japanese telecommunications and investment giant, has overtaken automotive manufacturer Toyota to become the company with the largest market capitalization on the Tokyo Stock Exchange. This marks a significant shift, as Toyota had held the top position for 22 years.

The surge in SoftBank's valuation is largely attributed to its strategic investments in artificial intelligence (AI). The company's market capitalization reached approximately 46 trillion yen (about $288 billion), momentarily surpassing Toyota, whose shares experienced a decline.

Investor enthusiasm for the AI sector, coupled with reports of SoftBank's substantial investment in OpenAI, the creator of ChatGPT, has significantly boosted the firm's stock. Further fueling its rise, reports suggest SoftBank plans to invest up to 75 billion euros in establishing an AI data center in France.

Toyota had maintained its leading position since December 2003. SoftBank's impressive performance on this particular Monday also played a role in the broader market, helping the Nikkei index reach a new intraday record by surpassing 67,000 points for the first time during early trading.
