The supply dataset — how many were offered, day by day
Every value list in this niche tells you what an item is worth. A couple of Adopt Me sites also show how many offers are live at this moment. What none of them keeps is the count from one day to the next — so you can see a number rise or fall, not just read today’s. We record it every day, for three Roblox trading games, and this page hands you the whole record as one file.

9,099 observations so far, from 2026-08-28 to 2026-09-09. A new day is added every morning.
A row says: on this day, the item turned up this many times in the listings we read. That is a count of offers, not a count of how many exist in the game, and not a price. Traderie hands out its 1,539 most recently updated listings and no more. On the last run that covered 69 minutes of trading. These counts are what people are listing now — not everything that exists. An item can be rare and barely listed, or common and listed constantly — those are different facts, and this file is about the second one.
How to read a gap
A missing day is not a zero and not a measurement. It means one of two things: the count did not change, or the item had no listing in that day’s window at all. We cannot tell those apart from the file alone, and we would rather say so than let you read a gap as a fact. An observed zero is a row of its own, with selling=0 — that one says none of that day’s window was this item, which is weaker than “none were on offer”. Before an item’s first row there is no claim at all: we had not seen it yet.
What is in a row
game, item, slug, day, selling, buying. There are no player names, no account IDs and nothing else identifying a person — this audience is largely children, and we do not collect that. selling counts how much of that day’s window the item filled, so a 0 means none turned up — not that none were on offer. An empty buying means we were not recording that number yet, which is not the same as zero.
Where it comes from
The listings are public offers on Traderie, read once a day. We count them; we do not republish anyone’s listings, prices or profiles. Our own item values are a separate thing and come from community value lists — see how we value items.
Mirrors
The same file is on Kaggle and on GitHub, where git keeps a commit per day so you can diff one day against another. Both are copies; the file on this page is the current one.
