Polymarket, the only major prediction platform tracking this event, shows a 0% probability that OpenAI will release GPT-6 by the end of June 2026, based on $220,000 in trading volume. The market's unanimous expectation suggests that traders view the timeline as highly improbable, likely due to the complexity of developing and deploying such advanced AI systems. No data is available from Kalshi or Manifold, limiting cross-platform comparison, but Polymarket's liquidity indicates a strong consensus among forecasters.
The absence of any positive probability reflects a broader industry understanding that GPT-5, the predecessor, has not yet been released, and the pace of AI development typically spans years between major iterations. Without specific news headlines to explain the shift, the market appears to be pricing in the inherent uncertainty and long development cycles associated with cutting-edge AI. Traders may also be factoring in regulatory hurdles and safety considerations that could delay deployment.
While the 0% figure is striking, it is not uncommon for prediction markets to assign zero probability to events seen as extremely unlikely, especially when the resolution date is far off and no concrete progress has been announced. The volume of $220,000 suggests active interest, but the lack of any bullish bets underscores the market's conviction that GPT-6 will not arrive by mid-2026.
