Frequently asked questions

What is the Steam Siege Price Index?

The Steam Siege Price Index is a daily index from Double Holo Research that follows the combined price of every priced card from the Pokemon Steam Siege set. It started at 1,000 on January 20, 2025 and was at 2,409.65 on October 18, 2026.

Is the Pokemon Steam Siege set going up in value?

Double Holo does not forecast prices. As of October 18, 2026, the Steam Siege Price Index was up 0.30% over 30 days and up 18.66% over one year.

What is the most valuable card in the Pokemon Steam Siege set?

Gardevoir EX had the highest price in the index on October 18, 2026, at $109.17.

How is the Steam Siege Price Index calculated?

It adds up the daily market price of every card in the index. Each day the change is measured only on cards that were in the index on both days, so a card that joins never moves the level on its first day. A day is published when cards making up at least 90% of the index value have a recent price.

Can I download the Steam Siege Price Index data?
