Audience size is not the same as quality. These newer or smaller shows score at the top on measured substance, so they earn a spotlight regardless of view count.

Rising stars by information density. Gradient Dissent: Information density 61. Last Week in AI: Information density 61. Y Combinator: Information density 33. The Gradient Podcast: Information density 16. Machine Learning Stree…: Information density 21. The TWIML AI Podcast: Information density 21. Information density counts named companies, people, figures, and mechanisms per minute of transcript.

How we score: every show is graded from its episode transcripts on information density (named companies, people, figures, and mechanisms per minute), specificity (concrete, checkable claims versus vague punditry), source attribution (how often a claim credits where it came from), and a prediction track record we resolve against what actually happened. The full, continuously updated board lives at [the podcast rankings](/rankings/podcasts).
