Sam Altman Rules Out OpenAI's $1 Trillion IPO For 2026

Sam Altman Rules Out OpenAI's $1 Trillion IPO For 2026

Altman told Fortune he blames rogue AI agents hacking sites like Hugging Face, and two days later SoftBank shares slid 13%.

  • Altman told Fortune's Alyson Shontell on September 12: 'I would say not 2026.'
  • He called going public now 'an ill-advised moment,' citing hacks like the Hugging Face breach.
  • SoftBank shares fell 12% to 13% on September 14, two days after the interview ran.

Why it matters: Caution announced by the founder became, two days later, a loss booked by the investor.
