Pokemon TCG Weekly Roundup — Week 24 2026

Market Overview

Week 24 delivered a mixed performance across the Pokemon TCG market, with older sets demonstrating continued strength while newer releases faced headwinds. The most notable development was Steam Siege's explosive 16.7% gain, pushing the 2016 XY set above £1,470 despite our overvalued signal. This movement suggests collectors are increasingly viewing mid-era sets as undervalued relative to their WOTC counterparts.

The market showed clear divergence between vintage and modern product, with several SWSH-era sets posting notable losses. Champions Path led the declines at -7.8%, while Crown Zenith dropped 6.0%. This rotation out of pandemic-era product continues as investors reassess the long-term collectibility of sets released during peak market conditions.

ETB Watch

Elite Trainer Box activity remained subdued this week with no significant price movements to report. This follows the broader trend of ETB performance lagging sealed booster boxes as investors continue prioritising products with stronger long-term appreciation potential. The ETB market appears to be consolidating after recent volatility.

Chase Card Highlights

Individual chase cards showed minimal movement this week, suggesting the market's focus remains on sealed product accumulation rather than singles speculation. This environment often presents opportunities for patient investors to acquire high-grade vintage cards before the next grading cycle drives renewed interest. PSA and CGC populations continue expanding, making condition critical for future appreciation.

What's Hot This Week

Heat score data was unavailable this week, limiting our ability to identify emerging trends through social media sentiment and search volume metrics. However, market activity suggests continued institutional interest in XY-era product, with Steam Siege's breakout performance potentially signalling broader revaluation across the 2016-2017 period.

Investor Takeaway

• Steam Siege momentum: The 16.7% surge validates our thesis that mid-era XY sets remain undervalued despite short-term overvalued signals - consider any pullbacks as accumulation opportunities

• SWSH weakness persists: Champions Path and Crown Zenith declines reinforce concerns about pandemic-era valuations - avoid catching falling knives in this segment until clear bottoming signals emerge

• Hidden Fates strength: The 8.2% gain combined with our Strong Buy signal makes this the week's standout opportunity - premium SM special sets continue demonstrating institutional-grade performance
