Which podcast genres are oversaturated? Kids & Family has the widest gap on the map.
We mapped supply against demand across 19 podcast genres. Supply is the number of active shows in each category, scaled to a 0 to 100 index. Demand is a composite of listener search intent and discovery volume, also scored 0 to 100. The gap between them tells you where there are too many shows, and where there are not nearly enough.

Key findings
- 1.Kids & Family has the largest supply gap on the map: a demand score of 74 against a supply index of just 27. Parents are actively searching and the category is thinly served.
- 2.Business is the single most crowded genre with over 122,000 shows indexed, giving it a supply index of 100. Demand has not kept pace.
- 3.Music, TV & Film, History, and Science all show gap scores above 40, placing them firmly in the opportunity zone.
- 4.True Crime and News defy the saturation pattern: both are crowded but demand is high enough to keep them in the competitive (not oversaturated) category. Breaking in is hard but not futile.
- 5.Society & Culture and Education are the quieter saturation traps. Neither generates particularly high demand, but both categories are flooded with shows.
The saturation map
Each bubble is a genre. Horizontal position = supply (more shows to the right). Vertical position = demand (higher listener intent toward the top). Bubble size reflects the raw number of shows. Click any bubble to inspect the numbers.
Biggest supply gaps
Gap score = demand index minus supply index. A positive score means listener appetite outpaces available shows.

How to read this for your show
The map has four zones. The upper-left (high demand, low supply) is the opportunity zone. The upper-right (high demand, high supply) is competitive: difficult but worthwhile. The lower-left is the niche zone: lower competition but also a smaller audience ceiling. The lower-right is the danger zone: lots of shows chasing a relatively modest listener base.
A high gap score does not guarantee success in a genre. Kids & Family has the widest gap, but the bar for trust and quality is higher than almost any other category: parents are selective about what their children hear. TV & Film has a large gap partly because most shows in the category are low effort recap podcasts that listeners find and abandon quickly. The gap exists, but filling it meaningfully is a different challenge from simply launching in the category.
Use the map as a starting filter. A genre in the opportunity zone clears the first hurdle. The second hurdle is whether you have a specific, differentiated angle that the existing shows do not cover.
What "demand index" actually measures
The demand index is a composite of listener search volume (how often people search for podcasts in this genre), directory browse intent (category page visits on Apple Podcasts and Spotify), and average subscriber-to-show ratio across the top 100 shows in each category. It is scaled so that the highest-demand genre scores 100 and the lowest scores in the 30s.
The supply index is simpler: total active shows in the WhichPodcast index for that category, divided by the highest-supply genre (Business, at 122,000 shows) and multiplied by 100. A genre with 61,000 shows scores 50 on supply.
Methodology
- Source
- Show counts are from the WhichPodcast index of RSS-distributed podcasts as of July 2026. Each show is assigned its primary Apple Podcasts category. Demand scores are composites of anonymised search and browse data.
- Gap score
- Gap score = demand index minus supply index. A positive score indicates listener demand is higher than the current supply of shows. A negative score indicates the genre is oversupplied relative to search intent.
- Known limitations
- YouTube-only podcasts are excluded. This understates competition in Music and TV & Film in particular, where video podcasts dominate.
- Categories are broad. A show tagged Business and a show tagged Comedy both contribute one count each to their respective categories, regardless of audience overlap.
- Demand proxies have noise. Search volume for "kids podcasts" includes parents looking for audio for their children and podcast professionals researching the market. These are not the same intent.
- English-language data dominates. Non-English shows and demand are underrepresented.
