Joel Peterson’s one-hour Stanford lecture breaks down practical negotiation tactics and decision-making frameworks you can apply immediately. It covers how to prepare, frame discussions, and secure better outcomes—far more insight than typical years of experience.

Anthropic ran Project Deal, where Claude AI agents negotiated buying and selling personal items on behalf of 69 employees in a Slack-based classifieds market. They compared outcomes between a top-tier model (Opus 4.5) and a smaller one (Haiku 4.5), finding that smarter agents secured higher prices and more deals—differences participants didn’t notice. In total, agents struck 186 deals worth just over $4,000.
