What is Kanto Research?

The fair-market scoreboard for graded Pokemon cards.

We track every graded sale on eBay, calculate fair market value per card, and ping you when the live market drops below it. No predictions. No hype. Just the numbers.

Why this exists

Pokemon cards have appreciated 3,821% over the last 20 years. The S&P 500 did 483% over the same stretch (WSJ, 2025).

Millions of graded cards trade on eBay every year. Billions of dollars move through that market. And yet there’s no Bloomberg terminal for it — just you, a browser tab, and the hope you’re not overpaying.

We built the terminal.

How it works

01
We track every graded sale
Every sold listing on eBay — graded Pokemon cards only, English only — is captured continuously. 194,019 sales and counting.
02
We match each listing to its exact card
eBay titles are chaos. Our resolver parses each one and matches it to the right card, set, and variant in our catalog of 19,889 cards across 172 sets. Ambiguous matches get flagged, not guessed.
03
We calculate fair market value
90-day rolling median per (card, variant, grade) pair. Every value ships with a confidence tier so you know how much data stands behind the number.
04
We surface the live deals
Active auctions and BIN listings are refreshed every 5 minutes and scored against FMV. When a card drops meaningfully below fair value, it hits the board — and your alerts inbox.

Bill
Market Analyst · AI

Named after the Cerulean Cape researcher who built the original Pokemon Storage System — sorting cards is literally in his name. Bill writes our daily market recaps, deal takes, and set deep dives. Every number he quotes is a direct query against the database you’re looking at. He doesn’t guess, he doesn’t predict, and he doesn’t hype.

Disclosure: Bill is an AI, not a human. Every article he publishes is reviewed by a human editor first. He cites the specific sales data behind every claim. He does not give financial advice, predict future prices, or tell you what to buy.

How we make money

Kanto Research is free. Always.

When you click a deal and buy through eBay, we earn a small commission from eBay Partner Network. It doesn’t add anything to your price — eBay pays us out of their margin, not yours. That commission is what keeps the platform running and free for everyone.

We show the affiliate link on every deal because transparency is the product. If a card has a better price somewhere else, we’ll say so.

Where the data comes from

We ingest verified sold listings from eBay continuously. Every title gets parsed into a structured record (card, set, variant, grade, price) and written to our database. Active auctions and BIN listings refresh every 5 minutes so deal alerts reflect the live board, not yesterday’s.

Our catalog is pulled from the official Pokemon TCG API and cross-referenced against the community-maintained Pokemon TCG Spreadsheet. 19,889 cards, 172 sets, all graded variants tracked.

Full technical breakdown — match rate, confidence tiers, data cleaning — is on the methodology page.

What we promise

Every number is sourced
If we show a stat, it traces back to a specific sale in our database. If we can’t query it, we don’t publish it.
No financial advice
We’re a research tool, not a broker. We show the scoreboard. You decide what to do with it.
No price predictions
Past and present only. Future price targets are for people selling you a newsletter.
AI content is disclosed
When Bill writes something, the page says so. Human editorial oversight is non-negotiable.
Affiliate is disclosed
We earn commission when you buy through our eBay links. That’s how Alerts stays free forever.
Methodology is public
Our full data pipeline is documented and open. We’d rather explain the process than hide behind a black box.
