Masayoshi Son's Net Worth Falls $4.8 Billion to $44.9 Billion

Masayoshi Son is worth $44.9 billion, according to Forbes' real-time billionaires data, after a $4.8 billion fall in the latest live reading. Two reports about his company SoftBank appeared on November 6: one on a sharp fall in its shares and one on a blocked acquisition.

What the headlines report

• Billionaires.Africa reported that Son lost $3.9 billion as SoftBank shares fell 11% in what it called an Asian chip rout.
• Forbes reported that China blocked a $5.4 billion deal for SoftBank to acquire ABB Robotics.

The $3.9 billion loss in the Billionaires.Africa report is smaller than the live figure, which has since changed and now shows a $4.8 billion decline. The live data is as of 01:03 UTC on November 7, 2026, and covers the November 6 trading session.

What his fortune is built on

Son's wealth comes from telecom and investments, and Forbes lists him in the finance and investments industry. He is based in Japan and ranks No. 44 on Forbes' real-time list of billionaires. Both reports centre on SoftBank, the company most closely tied to his fortune.

Because so much of his wealth is linked to SoftBank, moves in the company's share price and news about its deals tend to show up quickly in his live net worth. To see where he stands, browse the full billionaires list.
