Japan Daily Briefing

SpaceX began trading at $150 vs its $135 IPO price, hitting the Nasdaq at a $1.75T valuation and briefly making Elon Musk the world's first trillionaire. SoftBank Group's Vision Fund holds direct SpaceX equity, making SFTBY's +10.69% today the most direct Japan-listed SpaceX proxy available to retail investors. The IPO validates SoftBank CEO Masayoshi Son's early AI infrastructure bets. For Japan tech investors without direct Nasdaq access, SFTBY is now the consensus expression.

Toyo Keizai has identified nine Japan-listed stocks with deep ties to SpaceX, Anthropic, and OpenAI — the 'AI 3 brothers' in this week's record IPO cycle. Tokyo Electron (TOELY +11%) is the most prominent: its etching and atomic layer deposition tools are embedded in every AI chip fab worldwide. Advantest and Disco Corp are among the others on the list. With the SpaceX IPO generating record capital flows into AI infrastructure, the Japan semicap supplier universe is the indirect beneficiary of every dollar that flows into SPACEX, NVDA, and the Anthropic/OpenAI IPO pipeline.

Newly appointed Mitsui Sumitomo Marine & Fire Insurance president Hiroyuki Kaiyama laid out an FY2030 adjusted profit target of ¥280 billion, contingent on the 2027 merger with Aioi Nissay Dowa Insurance completing on schedule. The merged entity would create one of Japan's largest P&C insurers. Insurance M&A within Japan's financial sector has been accelerating under TSE governance pressure: combined entities achieve better capital efficiency ratios and escape the PBR<1 discount. Watch for a TSE Prime Market re-rating once the merger synergy plan is formalized.
