OpenAI's ChatGPT model forecasts a 50% probability that Bitcoin (BTC) will fall below $100,000 by the end of 2025. Currently, Bitcoin is trading at $111,044, having decreased by 3.5% in the past 24 hours and over 10% in the past week. The model also suggests a 20% likelihood of Bitcoin remaining under $100,000 for more than two weeks, with a 30% chance of avoiding such a decline through the year's end. Key risks include macroeconomic shocks, tighter monetary policy, and regulatory pressures, while potential support could come from ETF inflows and fiscal easing in 2026.
