Forecast Sees Claude Fable 5 Running Locally on High-End PCs Within Two Years

Prediction-market platform Polymarket said on July 7, 2026 that Anthropic's frontier model "Claude Fable 5" could run locally on high-end consumer hardware within about two years. Frontier models at Fable's level currently depend on cloud inference, and if the projection holds it would open the door to greater privacy, lower latency, offline use and more decentralized AI. The specific basis for the forecast was not stated, but it appears to assume progress in model compression and efficiency techniques such as quantization and Mixture of Experts (MoE), alongside advances in consumer hardware including larger unified memory and wider adoption of AI accelerators.
