Traders bet 72% OpenAI's GPT-6 'Astra' launches by Sept. 30

Polymarket traders give a 59% chance OpenAI's next model, internally named Astra (reportedly GPT-6), launches by Sept. 15 and ~72% by month's end, despite OpenAI slowing its release on Aug. 7 over cybersecurity risks. The company said it "cannot rule out critical cyber capabilities" under its safety framework.
