Introduction
Investor includes everything in Player — unlimited AI analysis, email alerts, daily briefing, all signal types, and the full sell optimizer — plus a second layer built for collectors who want to spot opportunities before they surface on Reddit.
At $24.99/month, or $249/year saving $50.88, Investor is designed for collectors who manage larger collections and want data-backed decisions at every step: what to acquire, when to hold, and where to sell.
Spec Intelligence feed
The Spec Intelligence feed scores every card in the CardMind catalog from 0 to 10, updated daily. The score aggregates multiple factors:
- Buylist motion — Is the Card Kingdom buylist rising, flat, or falling?
- Listing depletion — Are NM copies disappearing from TCGPlayer?
- Tournament inclusion — Is this card appearing in more lists than last week?
- Volume anomalies — Is transaction volume higher than the 30-day average?
Cards are sorted into grade tiers: A (strong conviction, score 8–10), B (moderate, score 5–7), and C (low/watch, score 2–4). Each card's score is transparent — you can see exactly which factors contributed and how much each one weighed.
CardMind publishes a running accuracy track record for the Spec feed, showing hit rates and misses over time. If the spec feed predicted a card would move and it did not, that is visible in the record.
Buylist signals
CardMind tracks Card Kingdom buylist prices daily across the full catalog. When a buylist price changes, a signal fires. These signals appear in your feed alongside the standard price and tournament signals.
Buylist motion tends to lead retail price movement. When a dealer raises their buylist offer, it reflects internal inventory confidence — they expect to sell that card at a higher price soon. A rising buylist is often the first data point that shows up before a card spikes on TCGPlayer.
The inverse is also useful: a falling buylist is a signal that dealer appetite for that card is declining. For collectors watching a card they own, a buylist drop can be a useful exit indicator before retail prices follow.
Buylist signals are Investor-only because they require daily buylist ingestion and change-detection across the full catalog — a data pipeline not included in lower tiers.
Weekly digest email
On Sunday evening, Investor accounts receive a weekly summary covering the past seven days:
- Top movers in your collection — Cards that gained or lost the most value this week
- Signal summary — How many signals fired, which types, and which cards triggered them
- Spec score changes — Cards that moved significantly on the Spec Intelligence feed
The digest is designed to be a five-minute read before Monday trading activity begins. It complements the daily briefing rather than duplicating it — the briefing is real-time and action-focused, the digest is a week-in-review.
Monthly accuracy report
CardMind will publish a monthly accuracy report starting July 2026, once 90 days of signal history have accumulated. The report will show:
- How many signals of each type fired in the past 30, 60, and 90 days
- What percentage of those signals preceded price movement in the predicted direction
- How the Spec Intelligence scores correlated with actual price outcomes
- Misses: signals that fired but the card did not move as expected
The report will be published at /accuracy and included in the monthly digest for Investor accounts. Transparency about signal quality is part of what separates a data platform from speculation.
Deck Intelligence — AI + Spec overlay
Investor extends the Deck Intelligence feature with a spec overlay: after CardMind analyzes your deck, it flags which cards in the list have active Spec Intelligence scores above a threshold.
This is useful in two directions. If you are planning to acquire cards to complete a deck, the overlay tells you which ones are under active spec pressure — cards worth acquiring sooner rather than waiting. If you already own cards in the list, it highlights which ones have elevated scores and might be worth watching or selling.
Investor accounts also get the full AI assessment from the Player tier: strategic analysis of deck strengths, weaknesses, and upgrade paths based on your collection. The spec overlay adds another data layer on top of that analysis.
Who it is for
Investor is designed for:
- Collectors with $1,000 or more in collection value who want to maximize what their collection is worth over time
- Spec-oriented collectors who buy ahead of demand and want scored, transparent data to back those decisions
- Store owners and vendors who want a daily data signal on what is moving and what dealers are paying before they price their inventory
