Rising speculation over Federal Reserve leadership change and historical policy patterns add to bullish sentiment for early 2025.

Anthropic tested AI agents on 405 real-world smart contracts and simulated $550.1 million in stolen cryptocurrency. Newer models exploited 34 contracts deployed after March 2025 for up to $4.6 million, with Opus 4.5 leading at $4.5 million. The agents also discovered two previously unknown zero-day vulnerabilities in live contracts worth $3,694 in test revenue.

Anthropic demonstrated that advanced AI models successfully identified and exploited vulnerabilities in blockchain smart contracts during controlled testing. The company tested 10 leading AI systems against 405 previously hacked contracts from 2020–2025, with agents exploiting over half and simulating theft of approximately $550.1M in value. When restricted to 34 contracts exploited after March 1, 2025, Claude Opus 4.5, Claude Sonnet 4.5, and GPT-5 generated working exploits worth $4.6M in simulated value, according to a recent study conducted with MATS and Anthropic Fellows.
