What this is
Whether revenue from the One Piece Card Game is published on its own: it is not. Figures of $300–400m that circulate online have no stated source.
How it’s built
- From an article on the card marketplace Misprint about the size of the One Piece card market.
What we assumed
- Taken at its word.Bandai Namco reports the card game inside a wider toys and hobby segment, which fits the article's statement.
Sanity check
Hence the chart shows a ceiling from Bandai's wider segment rather than a figure for the card game.
Where it comes from
The line in the source
Standalone One Piece Card Game revenue is not publicly disclosed.
