Most Valuable Pokémon Cards: New Study Reveals Which Cards Are Rising in Value

Pokémon cards have gone from playground currency to serious collectibles, and some of those old cards sitting in binders and boxes are now worth ridiculous amounts of money.

The Pokémon brand has generated an estimated $148 billion USD in profits since launching 30 years ago, but collectors have managed to get a piece of that enormous pie too. Pokémon first appeared on collectible cards in 1996, and rarity, special features, condition, and professional grading have helped turn certain cards into incredibly valuable collectibles.

The most extreme example came in February 2026, when Logan Paul resold a 1998 Pikachu card for more than $16.2 million.

Of course, finding a Pokémon card worth millions is a little like catching an actual Mewtwo. Still, a new study from idealo suggests there are plenty of Pokémon cards gaining serious value, including some that collectors might not immediately expect.

The study analyzed historical pricing data from PriceCharting for ungraded Pokémon cards valued above $9.94. Researchers compared prices between March 2025 and March 2026, looking at individual cards, complete Pokémon card sets, and the average performance of cards featuring specific Pokémon.

One card absolutely crushed the competition. The Japanese Snorlax LV. X #127 increased in value by a massive 691% since March 2025, giving it the largest price increase of any individual Pokémon card included in the study.

Snorlax apparently figured out how to make money while sleeping. Another surprising winner was Plusle. The Generation III Electric-type Pokémon, usually paired with Minun, saw cards featuring the character increase by an average of 263% over the year. That was the highest average increase for any Pokémon analyzed.

The bigger story, however, is what happened across the Pokémon card market as a whole. According to the study, the average ungraded Pokémon card worth more than $10 increased in value by 71.5% between March 2025 and March 2026. For comparison, Google shares increased 84.3% during the same period.

That certainly doesn’t mean everyone should empty their investment account and start buying booster packs. Pokémon cards can be unpredictable, and there’s no guarantee that a card climbing today will continue gaining value tomorrow. It does show why Pokémon card investing has become much more than a niche hobby for collectors.

Some cards originally bought by kids for the equivalent of only a few euros during the 1990s are now worth thousands. Even more surprising, certain Pokémon card sets purchased just a year ago are now valued at around four times their original price.

When it comes to popularity, one Pokémon still rules the mountain. Charizard is the most searched-for Pokémon when people look for cards featuring the original 151 Pokémon. idealo used Ahrefs Keywords Explorer to combine worldwide search volume for the various card versions associated with each Generation I character, and Charizard came out on top.

Not exactly a shock. Charizard cards have been collector favorites for decades, and that fire-breathing orange monster continues to have an absurd hold on Pokémon fans.

To see how Pokémon cards compared with more conventional investments, idealo also calculated the average monthly price appreciation of qualifying cards and plotted their performance against major global technology stocks and market indexes.

The results make a pretty good argument for checking that old Pokémon card collection before tossing it into the donation pile.

The cards worth watching aren’t necessarily limited to the obvious icons, either. A Japanese Snorlax card producing a 691% increase and Plusle cards averaging 263% growth show how strange and unpredictable the collectible card market can be.

Condition still matters, professional grading can have a major impact on resale value, and rarity remains one of the biggest factors in determining what collectors are willing to pay. There’s also plenty of risk involved, so Pokémon cards shouldn’t automatically be treated like stocks simply because some have produced impressive returns.

Still, if you collected Pokémon cards as a kid, it might be time to dig out that binder. Just try not to get too excited when you find 37 battered Energy cards and a Psyduck with a soda stain on it.
