AI valuation concerns drive selling

Investors reacted to comments from industry leaders. OpenAI CEO Sam Altman stated the company would likely delay a stock sale until next year. This decision postpones potential cash inflows for early investors. Softbank Group shares rose 7.5 percent in Tokyo. This move recouped previous overnight losses for the major OpenAI investor.

Anthropic CEO Dario Amodei called for a global slowdown in AI development. He cited safety concerns for humanity. Mizuho Bank analysts noted that competition among U.S. firms and between the U.S. and China remains intense. This intense rivalry makes a coordinated industry slowdown uncertain. The GN auto markets/indices data reflects these broader sector pressures.

Energy prices rise on supply risks

Benchmark U.S. crude oil prices increased 2.19 percent to $103.61 per barrel. Brent crude gained 2.13 percent to $107.93 per barrel. Middle East conflict continues to restrict global crude flows. A key Saudi pipeline is out of service for weeks. This follows an attack that targeted infrastructure near the Strait of Hormuz.

The U.S. dollar gained ground against the Japanese yen. The exchange rate moved to 154.99 yen from 154.30 yen. The euro weakened against the dollar. The currency pair fell to $1.1533 from $1.1557. These moves reflect shifting safe-haven demand in global financial markets.
