What Bloomberg reported
Crypto Briefing's account, citing Bloomberg, doesn't include a direct quote from Son on safety, and it doesn't say where he raised the concern. LeoDex News couldn't independently verify Bloomberg's report.
His message in June was very different.
At SoftBank's annual general meeting on June 24, 2026, Son pushed back on investors worried that AI valuations had run too far, framing those bubble concerns as an insult to the technology itself.
he said AI is “still in its early stages”
He's also pulled forward his target for artificial superintelligence (which he defines as AI 10,000 times smarter than humans) to within two years, Crypto Briefing reported.
A stock under pressure
On September 14, 2026, SoftBank shares fell more than 13% after leaders from OpenAI and Anthropic expressed caution about safety risks in frontier model development, according to Crypto Briefing. It was SoftBank's steepest single drop in almost three months.
Executives at both labs have also called for oversight of self-improving AI systems.
The money on the line isn't small. SoftBank raised $11.1 billion through a junk bond sale this year to finance its AI push, at a time of rising borrowing costs, the outlet reported. That sits alongside OpenAI commitments projected to hit $65 billion by October 2026.
Costs and timelines
Crypto Briefing's analysis argued that if oversight of frontier AI tightens, development timelines could stretch and costs could rise. That's a scenario, not a settled outcome, and it's the outlet's framing rather than LeoDex News's view.
The report says Son voiced concern. It doesn't describe any change to SoftBank's AI investments or to its OpenAI commitments.
