RBX Invest tracks the value, supply, marketplace sales, free claims, and release absorption of Roblox Classic and UGC Limiteds over time.
Market value is each item’s Recent Average Price multiplied by the copies that exist, added across the tracked market.
For one Limited, market value is its Recent Average Price multiplied by the copies that exist. RBX Invest adds that value across tracked tradable Limiteds and separates Roblox-made Classics from creator-made UGC Limiteds.
Classic Limiteds were released by Roblox and form a mostly closed catalog. UGC Limiteds are released by independent creators, so their item count and supply continue to grow as new finite releases appear.
No. Sales are marketplace purchases recorded in Robux. Item-for-item trades are not included because sales and trades are separate Roblox systems.
Supply is the number of Limited items or copies that exist. Sold out applies to paid finite UGC releases with no creator inventory remaining. Claimed includes copies taken from a finite release, whether the release was paid or free.
Each cohort groups finite UGC supply released in the same calendar month or week. The bars show released, claimed, and still-available copies; the curves and heatmap show how much of that same release supply had been claimed at matching ages.
The earliest available records begin May 7, 2021. The series uses Roblox’s published per-item daily sales history and RBX Invest snapshots. Days before direct recording began are reconstructed from that published history and identified as estimates; scheduled jobs refresh the daily market series and release aggregates.
