What Moved the Market
-
SoftBank Group Collapse Triggers Broader Retreat: SoftBank Group shares fell over 12% after reports emerged that OpenAI was considering a delay to its initial public offering—a major blow given SoftBank's substantial exposure to AI startups and infrastructure investments. The selloff in Japan's largest company by market capitalization spread contagion across the broader index.
-
Profit-Taking After Record Highs: The Nikkei 225 had surged 4.69% in the previous session on Micron Technology's upbeat earnings guidance, which reignited confidence in the semiconductor and AI supply chain. Friday's decline represents profit-taking from investors cashing in on those recent gains.
-
Global Tech Volatility Spills Into Tokyo: The reversal reflects broader uncertainty in global technology valuations, particularly around AI infrastructure and startup exit timelines. This follows a period where Japanese equities outpaced U.S. markets on AI euphoria.

Corporate Headlines
SoftBank Group Takes Major Hit on OpenAI IPO Delay Uncertainty: SoftBank's aggressive expansion into AI infrastructure, including its proposed 75 billion euro data center investment in France, has made the company highly dependent on successful exits from its startup portfolio. The OpenAI IPO delay has cast doubt on near-term liquidity events and valuations for other AI-focused portfolio companies, prompting institutional investors to reassess positions.
Oracle Japan FY26 Cloud Growth Outpaces Margin Pressure: In contrast to the broader selloff, Oracle Japan reported fiscal 2026 cloud revenue surging 34%, though margins remain pressured by infrastructure costs and competitive intensity. The results underline the divergent fortunes within the tech sector between established cloud providers and speculative AI plays.
BOJ & Macro Watch
-
Yen Remains Subdued Near 156.5 USD/JPY: The Bank of Japan's cautious policy stance—maintaining its 0.5% short-term rate—continues to support yen weakness. Strategists expect the yen to test 160 per dollar or beyond by end-2026 on persistent US-Japan yield differentials.
-
Next BOJ Decision Awaited: With equity volatility rising, investors will be monitoring for any hawkish signals from BOJ officials on future rate paths, though near-term expectations remain for a hold at the current level.
What to Watch Tomorrow
- Risk-On/Risk-Off Sentiment: Monitor whether Friday's selloff stabilizes or extends into the following week, particularly any fresh commentary from SoftBank management or clarification on OpenAI's IPO timeline.
- Semiconductor Earnings Revisions: Track analyst downgrades for chipmakers and AI infrastructure suppliers following the broader tech reassessment.
- BOJ Officials' Statements: Any remarks from Bank of Japan board members on exchange rate stability or financial conditions could impact currency pairs and equity valuations.
