Is the Mewtwo Run Real? Five PSA 10s, Nine Months, and One Missing Answer

In September 2026, Mewtwo had what PSA called a record month. Five PSA 10 Mewtwo cards from different sets reportedly sold for between $40,800 and $264,000. Here is what moved, what supports it, what argues against it and what we still do not know.

What moved

Five PSA 10 Mewtwo cards from releases dated 2002 through 2009 posted sharply higher reported sales. The following figures are drawn from public PriceCharting reports and remain subject to verification against original transactions.

PSA Vault reportedly counted Mewtwo transactions above $50,000 at 5 in July, 9 in August and 18 in September. This count also requires confirmation from the original source.

What supports it

The strongest evidence is breadth. One card jumping may reflect one determined buyer. Multiple Mewtwo cards across different releases rising together is harder to dismiss.

• Different cards, same direction. A set card, a tournament promo, a reverse foil, an LV.X and a game promo all moved higher.
• Higher reported sales. For each card in the table, the selected reported transactions rise in sequence. This is not proof that every transaction rose.
• More high-dollar activity. The reported count of $50,000-plus Mewtwo sales increased from July to September.
• Multiple marketplaces. Reported transactions span platforms including Fanatics Collect and ALT, subject to original-record verification.

What argues against it

Each card trades infrequently. A small number of auctions can move the visible price sharply without establishing a durable market level.

• Thin sale counts. A handful of transactions is a narrow basis for declaring a new price level.
• Small populations. Reported PSA 10 populations of 34 for Delta Species and 46 for Rocket's Mewtwo mean a small number of bidders may have an outsized effect.
• Nearby sales disagree. Two Rocket's Mewtwo PSA 10s reportedly sold one day apart for $30,000 and $35,400, an 18% difference.
• Sharp reversals happen. A modern Mewtwo ex PSA 10 reportedly moved from $45,600 to $23,100 in 12 days before a later $78,000 sale. This sequence needs primary-source verification.
• Reported does not always mean settled. Public results may not confirm whether payment was completed.

Why did it move?

No clear cause has been confirmed. We have not identified a public event before the earliest major March jumps that adequately explains the movement across these cards.

The timing is the interesting part. The Rumble and Rocket's Mewtwo examples reportedly rose more than threefold within roughly a week of each other in March, six months before the September headlines.

Anything that explains the run has to explain March, not September.

A narrative that appeared only after prices rose is not evidence of what caused the rise. A dated, earlier catalyst would change this assessment. Until then, “we do not know” is more useful than an attractive guess.

What would change this read

The next transactions matter more than the next headline. These are the observable developments worth following:

• Next PSA 10 sales. Do subsequent confirmed transactions approach September prices or land materially below them?
• The PSA 9 ladder. Do lower grades show similar movement or is activity concentrated in PSA 10?
• Continued breadth. Does the pattern persist across different Mewtwo cards or narrow to a few exceptional copies?
• A dated catalyst. Does credible evidence emerge of an event before the March moves?

For now, the Mewtwo run is a broad reported move built on thin sales, with its cause still unknown. That is a reason to keep checking evidence, not to forecast a price.
