Nikkei 225 rises 1.73% to 63268.37 as AI-linked shares lead Tokyo

Japan's Nikkei 225 rose 1.73% on Tuesday, standing at 63268.37 at 15:25 Tokyo time. The advance ended a three-session losing streak.

What happened

The Nikkei 225 gained 1078.72 points from the previous close of 62189.65. The reading was taken at 15:25 Tokyo time, five minutes before the end of the afternoon session, which runs until 15:30. The index had fallen in each of the previous three sessions, so Tuesday's move reversed that run.

Technology shares drove the rise. Stocks linked to artificial intelligence, including Advantest, SoftBank and Tokyo Electron, supported the index. Advantest and Tokyo Electron are chip-related names, and SoftBank is also tied to the AI theme through its investments.

Two developments fed the mood in Tokyo. Anthropic, the US artificial intelligence company, announced plans for an initial public offering in the United States. Separately, American semiconductor stocks advanced in the preceding US session, and Japanese chip-related shares followed.

The reaction across other instruments

In currency markets, USD/JPY stood at 157.80 at 06:45 UTC. That is 0.33 yen, or 0.21%, above the previous close of 157.47. The figure is an intraday level and can change before the Asian day ends.

The USD/JPY quote shows how many yen one US dollar costs. A higher figure means the yen is weaker against the dollar. The quote rose on the day, and the equity index rose as well. The two moves happened on the same day, but this report does not assume a connection between them.

Both figures point upward, and they are reported here side by side only to show the scale of each move.

Background and previous values

The Nikkei 225 is a price-weighted index of 225 large companies listed on the Tokyo Stock Exchange. Its level is often used as shorthand for the Japanese equity market. Because several of its heavily weighted members are technology and chip-related companies, news about AI and semiconductors can shift the index on a given day.

The previous close of 62189.65 came at the end of a three-session decline. Tuesday's advance of 1.73% therefore started from that lower base. The index finished the reading period 1078.72 points higher than where it ended Monday.

The Tokyo Stock Exchange trades in two parts each day. The morning session runs from 09:00 to 11:30, and the afternoon session from 12:30 to 15:30, Tokyo time. The 15:25 reading sits close to the final price of the day, but it is not the official close.

The AI theme in Tokyo trading

The three companies named in market commentary operate in different parts of the technology chain. Advantest and Tokyo Electron are linked to semiconductors. SoftBank is linked to AI through its investment activity. When US chip stocks rise overnight, Japanese companies in the same theme often attract attention at the open in Tokyo.

The Anthropic announcement added a company-specific element. A planned US listing of a leading AI developer draws attention to the whole sector, including suppliers and investors in other countries. The terms and timing of the offering are not given in the material available here.

Why it matters

The session shows how closely Japanese equities follow global themes in technology. A US company's plan to list shares in the United States, together with gains in US chip stocks, coincided with a broad rise in the three AI-linked names cited. Advantest, SoftBank and Tokyo Electron each have a different business model, but all three are tied to the AI theme in market commentary.

The move also ended a losing streak. The change in direction after three declining sessions is a factual marker of how sentiment shifted on the day. Trading volume, market breadth and sector index figures are not available here, so the contribution of each stock cannot be quantified.

For international investors, the yen is an additional factor, because moves in USD/JPY change the value of Japanese assets when measured in dollars. The pair rose 0.21% on the day to 157.80, a modest change. Currency drivers for the day are not detailed here.

What to watch next

The next point of reference is the official Nikkei 225 close for Oct. 27, which will confirm the level after the final minutes of trading. It can be compared with the 15:25 figure of 63268.37 and with the previous close of 62189.65.

On the corporate side, further details of Anthropic's US IPO plans may shape sentiment toward AI-linked shares in Japan. Timing and terms of the offering have not been announced in the material available here. Moves in US semiconductor stocks in the next US session will also be a reference for Advantest and Tokyo Electron when Tokyo reopens.

In currency markets, USD/JPY at 157.80 remains an intraday level. A settled reference will come after the Asian and European sessions finish. No scheduled data releases are listed for the day, so market direction will depend on corporate news and moves in global technology shares.
