U.S. Senate Republicans released a final revised version of the Clarity bill to win Democratic support for a crypto market-structure measure. The 635-page text includes ethics rules accepted by President Donald Trump, protections for blockchain developers and changes to stablecoin reward provisions. It would bar federal officials from issuing, sponsoring or holding significant financial interests in digital assets and allow enforcement by state attorneys general. Violations could draw civil penalties up to $500,000.

The U.S.-China AI rivalry is moving toward using AI to build stronger AI, with companies focusing on coding, experiment design and training methods to boost next-generation models. The long-term goal is recursive self-improvement, in which AI produces improved successor models in a feedback loop. OpenAI, Anthropic and Google DeepMind cite progress, while analysts say the United States leads in AI-based independent research. Researchers and officials warn safety risks are rising, but neither country has publicly demonstrated fully autonomous recursive self-improvement.
