Grading Trends: Why Pokémon TCG Remains the King of the Slab

The Unstoppable Rise of Pokémon Grading

If you have spent any time in the hobby recently, you have likely noticed that the appetite for professionally graded Pokémon cards shows no signs of cooling down. According to a March 2026 report from GemRate, which tracks grading data across major services like PSA, CGC, and Beckett, the Pokémon TCG remains the most-graded trading card category by a significant margin.

This trend is not just holding steady; it is actively growing. PSA, the industry giant, reported a 3% increase in Pokémon TCG submissions in March 2026 compared to the previous month. Despite the market entering a phase of maturity, collectors are clearly still prioritising the protection and authentication of their collections. Whether it is to preserve a high-value chase card or to prepare for a potential resale, the "slab" remains the gold standard for many enthusiasts.

Why the Rush to Grade?

There are several factors driving this sustained interest. For many, it is about the investment potential. Data from PokeInvest indicates that the median PSA 10 price multiple for cards worth over $5 is approximately 13.7x the raw card value. When you see numbers like that, it is easy to understand why collectors are so eager to send their best pulls to a grading service.

However, the market is also becoming more discerning. With millions of slabs already in circulation, the difference between a PSA 9 and a PSA 10 can represent a massive gap in value. This is where the importance of pre-submission screening becomes critical. Sending a card to a professional grader is an investment of both time and money; if your card has hidden surface scratches or off-centre artwork, you might be paying for a grade that ultimately lowers the card's liquidity or value compared to its raw state.

Making Smarter Submission Decisions

Before you commit to the costs and wait times associated with professional grading, it is essential to perform your own due diligence. Many collectors are now turning to AI-assisted tools to get an objective look at their cards before they ever leave the house.

At GradingCardboard, we help collectors bridge this gap. You can use our free centering tool to instantly check if your card meets the strict alignment standards required for a high grade. If you want a more comprehensive breakdown, our AI Grading Reports provide detailed sub-scores for corners, edges, and surface condition for just £1 each. By identifying potential flaws early, you can decide whether a card is truly worth the submission fee or if it is better kept in a binder or a standard magnetic case.

Takeaway for Collectors

As the Pokémon TCG market continues to evolve, the data is clear: quality is king. With grading volumes rising, the market is becoming increasingly competitive. Before you pay for a professional service, take a moment to assess your card's condition objectively. Using AI pre-grading tools can save you from unnecessary submission fees and help you focus your budget on the cards that truly have the potential to earn that coveted top grade.
