What is Big Mama worth in GPO?
Big Mama's current trading value is approximately 2.6K (range 2.4K–2.9K), based on 4,804 observed Discord trades over the last solver run. Updated 2026-06-02.
How is the value calculated?
Values are derived from observed Discord trade messages using a ratio-chain solver against the anchor item. No editor opinions, no hand-tuned numbers. See /legal/methodology for the full math.
Why is the value a range, not one number?
The range is a 90% confidence band. The single headline number is the median; the band shows where the solver thinks the true value lives given noise.
Is Big Mama's demand High forever?
No. Demand is recomputed every solver run from the offered:wanted ratio in trade messages. Big Mama's current ratio is 2.98 (3,598 wanted vs 1,206 offered) — that's why demand is High right now.
