SoftBank slides as OpenAI IPO timing uncertainty weighs on AI-linked stocks

Chip stocks and U.S. indexes fell, fund flows turned negative and SoftBank dropped sharply as reports pointed to a possible OpenAI IPO delay into next year or as late as 2027.

Fact Check
Every element of the claim is corroborated. The BlockBeats flash and Nikkei Asia-sourced reporting (via Vespernews) both confirm SoftBank fell over/about 12% in Tokyo on June 26 2026 due to concerns over an OpenAI IPO delay. The Cryptopolitan article confirms the underlying report: OpenAI leaning toward a 2027 IPO at a $1 trillion valuation, delayed from late 2026, per a June 25 NYT report. BlockBeats also articulates the SoftBank-portfolio-benchmark angle, noting the delay removes a valuation anchor for SoftBank's many unlisted assets, which matches the claim's framing about uncertainty over SoftBank's private portfolio. Bloomberg and Nikkei headlines provide additional independent confirmation.

Summary

AI-linked equities sold off across Asia and the United States as uncertainty over OpenAI’s listing timeline weighed on sentiment, hitting SoftBank and semiconductor shares and contributing to weekly losses in U.S. stocks. SoftBank Group fell about 13% in Tokyo, Japan’s benchmark index dropped more than 4%, South Korea’s Kospi lost almost 6%, and U.S. technology shares weakened from futures into cash trading, with the Philadelphia Semiconductor index down about 4.7%-5% and the VIX up 8.91%. CNBC reported OpenAI has not set an IPO timetable and may delay a listing until next year, while earlier reporting cited by The New York Times said 2027 could be the earliest window; Bloomberg separately reported that Bank of America saw $8.5 billion of outflows from U.S. equities, the first in three months, as the chip selloff outweighed easing rate fears.
