In Episode 183 of the Investor Professor Podcast, we break down a major market-moving development: the Supreme Court’s 6–3 decision to strike down the bulk of the IEPA tariffs that had become a central pillar of President Trump’s trade agenda. With roughly $160 billion in tariff revenue in question and new 10–15% proposals already being floated under alternative legal authority, uncertainty is back at the forefront. We discuss how shifting trade policy affects corporate decision-making, capital spending, and global supply chains—especially at a time when inflation data (PCE) remains sticky and major indexes are treading water. We also preview a pivotal earnings week led by Nvidia, explore volatility across AI and software names, and examine the implications of a $200 million contract dispute between Anthropic and the U.S. government that could ripple through the broader AI ecosystem.

We close the episode on a more personal and reflective note, discussing value investor Guy Spier’s decision to wind down the Aquamarine Fund following a glioblastoma diagnosis. Drawing from his deeply honest letter to shareholders, we reflect on mentorship, integrity, and what truly matters in a profession that can often feel transactional and isolating. From tariffs and tech to gratitude and legacy, Episode 183 blends timely macro analysis with a perspective that goes beyond the numbers.
