Nintendo stands to make the least amount of money out of the incredibly popular, incredibly profitable Pokémon Go mobile app, according to at least one analyst as reported by Business Insider.

Launched just last week in North America and other parts of the world, Pokémon Go quickly soared to the top of the charts on iTunes and Google Play. It’s currently listed as the top free and top-grossing app on both mobile storefronts.

Estimates put the game’s revenue at anywhere from $1 million to $2.3 million a day. But it’s a little unclear how all of that money is being split up.

As the Wall Street Journal reports, that money likely goes to a number of companies, including Apple and Google, which both take a share of sales through their stores; developer Niantic (which Google parent company Alphabet invested in when Niantic was spun out of Google); The Pokémon Company (of which Nintendo owns 32 percent); and finally, Nintendo itself, which invested in Niantic’s creation of the game.

Both Apple and Google get 30 percent of revenue from in-app purchases on their stores. David Gibson, an analyst at Macquarie Research, delivered this estimate of game revenue breakdown to Business Insider:

The title was jointly developed by Niantic, Pokémon Company and Nintendo. It is unclear exactly what their economic interest is in the game, but we presume that out of every 100 units earned at the app store, 30 would go to Apple, 30 to Niantic, 30 to Pokémon and 10 to Nintendo.

The good news for all the companies involved is that there’s a lot of money to go around.

An App Annie analyst told Inverse that the firm could see the game pulling in a billion dollars a year once the server issues are smoothed out and the game launches worldwide. The game is the fastest mobile game ever to reach the number one spot for revenue on mobile stores, outpacing even Clash Royale, according to App Annie and VentureBeat.

That news has already had a substantial impact on Nintendo. On Monday, CNBC reported that the company saw a 25 percent jump in its stock value.

Rumor has the game hitting Japan in the coming week, which is sure to drive use and sales up as well.
