It’s Boxes and Lines Lite, where we break down the biggest market stories in just 10–15 minutes.

Ronan and JR break down why markets reacted so dramatically, how DeepSeek’s low-cost, high-performance AI models are shaking up the industry, and whether this is just another dot-com-style overreaction or a real shift in the AI arms race.
