The State of GPO Trading — September 2026
A dated Grand Piece Online market report off 206,118 recorded trades: most-traded items, 30- and 90-day value movers, when GPO trades, and the open CSV behind every figure.
Grand Piece Online's trade board ran on 206,118 recorded trade posts between 22 July and 8 September 2026, and the Mythical Fruit Chest is still the currency the rest of the market is priced in — it appears in 33,116 of them, 2.6 times more often on the wanted side than the offered side. The month's largest sustained move among liquid items was Leo's Inferno Hagoromo, up 163.8% in 30 days, against Dark Skeletal Shark Mask down 52.2%.

Published 8 September 2026. Every number on this page comes from our own trade corpus and can be recomputed from the CSV at the bottom.
What this report is built on
There is no official GPO value list. Every published "value" in this game is a consensus number, and the honest way to publish one is to say how many trades are behind it. Ours:
| Trade posts parsed | 206,118 |
| Date range | 2026-07-22 to 2026-09-08 (49 days) |
| Distinct posting accounts | 28,182 |
| Trading channels collected | 10 |
| Distinct items seen in trades | 264 |
| Items with a solved value | 148 |
| Solver | Rust solver v1 — chain + bundle + balanced windows, run 2026-09-08 03:32 UTC |
| Value anchor | Mythical Fruit Chest = 10,000 |
| Daily value history | 2026-06-11 to 2026-09-08 (90 days, 160 items) |
Values here are a relative index, not Beli and not dollars. An item at 50,000 trades for roughly five Mythical Fruit Chests. That is the only claim the number makes.
The most-traded items
Counted as the number of trade posts an item appears in, on either side.
| # | Item | Appearances | Offered | Wanted | Solved value |
|---|---|---|---|---|---|
| 1 | Mythical Fruit Chest | 33,116 | 11,556 | 30,280 | 13,225 |
| 2 | Pika | 29,127 | 15,999 | 13,562 | 11,193 |
| 3 | Dark Blade | 24,182 | 13,447 | 10,855 | 28,466 |
| 4 | All Seeing Eye | 21,241 | 4,930 | 17,134 | 96,514 |
| 5 | Legendary Fruit Chest | 17,402 | 11,451 | 8,867 | 4,654 |
| 6 | Dragon | 16,849 | 3,972 | 13,000 | 52,002 |
| 7 | Legendary Fish Bait | 16,801 | 3,617 | 13,243 | 8,438 |
| 8 | Thunder Club | 15,936 | 11,259 | 4,715 | 31,196 |
| 9 | Devil Fruit Rod | 14,269 | 8,415 | 5,888 | 35,534 |
| 10 | Mochi | 12,007 | 8,009 | 4,045 | 14,393 |
The top of this table is not the top of the value list. Mythical Fruit Chest ranks 70th of 148 by value and first by volume, because it is what people pay with. Dark Blade is the busiest weapon in the game and ranks 50th by value. Liquidity and price are close to unrelated in GPO: across the 147 items with both figures, the rank correlation between appearances and solved value is ρ = 0.19.
What traders want versus what they hold
The offered/wanted split is the cleanest demand signal in the corpus, because a trade post states both sides explicitly.
Both tables below use one gate — items appearing in at least 3,000 trade posts, 54 of the 264 items seen — and both are emitted by the generator (demand in the stats file) rather than cut from the CSV by hand. Below that floor a four-to-one ratio is a handful of posts.
Wanted far more often than offered (items ≥3,000 appearances):
| Item | Offered | Wanted | Wanted per offer |
|---|---|---|---|
| Legendary Fish Bait | 3,617 | 13,243 | 3.7× |
| All Seeing Eye | 4,930 | 17,134 | 3.5× |
| Dragon | 3,972 | 13,000 | 3.3× |
| Fish Bait | 1,065 | 3,260 | 3.1× |
| Mythical Fruit Chest | 11,556 | 30,280 | 2.6× |
Offered far more often than wanted (the same ≥3,000 gate):
| Item | Offered | Wanted | Offers per want |
|---|---|---|---|
| Ope | 7,687 | 1,062 | 7.2× |
| Biscuit | 8,624 | 1,349 | 6.4× |
| Buddha | 6,490 | 1,472 | 4.4× |
| Time-Rift Capsule | 2,603 | 615 | 4.2× |
| Roger's Ace | 4,801 | 1,408 | 3.4× |
Ope, Biscuit and Buddha are the fruits everybody is trying to move, at seven, six and four offers per want. There is a second thing true of all three: none of them qualifies for the movers table below, because their daily value series is too unstable to read a trend from — Ope moves a median 10.1% a day, Buddha 6.7%. The heavily-offered commodity fruits are also the worst-priced ones, which is the opposite of what a "more trades means a better number" intuition predicts.
The biggest value movers
An item qualifies for this table only if it is liquid and its value series is stable enough that a monthly move means something: ≥1,000 recorded trades, ≥60 daily price points, and a median day-over-day change of ≤5%. That leaves 43 of 148 items. All three thresholds are in the stats file under mover_gate, so the gate can be re-applied to the CSV without reading the script. The rest are excluded on purpose — 53 fall below the trade floor, 29 have too short a series, and 23 move more than 5% a day at the median, which is noise, not a market. Each end of the comparison is a 7-day median, never a single day's point.
30 days — 9 August to 8 September 2026 (40 items qualified):
| Item | 9 Aug | 8 Sep | Change | Trades |
|---|---|---|---|---|

| Iceborn Candy Cane | 723,966 | 625,646 | −13.6% | 2,878 |
| Inferno Rocket Blade | 11,990 | 9,697 | −19.1% | 1,340 |

90 days — the full price history, 14 June to 8 September 2026 (43 items qualified; the series begins 11 June, so the earliest date that can carry a 7-day median is 14 June, making this an 86-day window):
| Item | 14 Jun | 8 Sep | Change | Trades |
|---|---|---|---|---|
| Hover Pod | 7,726 | 19,099 | +147.2% | 10,210 |
| Coyote Outfit | 17,075 | 27,188 | +59.2% | 1,725 |
| Hollow's World Ender | 20,025 | 30,714 | +53.4% | 8,474 |
| Leo's Inferno Hagoromo | 165,388 | 249,341 | +50.8% | 11,116 |
| Dark Blade | 17,195 | 25,390 | +47.7% | 24,302 |
| Hie | 646 | 949 | +46.9% | 2,476 |
| Soul Cleaver | 32,298 | 43,300 | +34.1% | 4,821 |
| All Seeing Egg | 95,438 | 122,639 | +28.5% | 4,356 |
| Candy Cane | 384,847 | 332,307 | −13.7% | 5,949 |
| Prestige Fruitbag | 505,281 | 434,107 | −14.1% | 3,562 |
| Titan Shifter's Aura | 161,726 | 136,173 | −15.8% | 6,053 |
| Time-Rift Capsule | 27,971 | 23,204 | −17.0% | 3,218 |
| Prestige Firework Lancer | 1,328,373 | 1,023,574 | −22.9% | 1,193 |
| Prestige World Ender | 1,848,714 | 1,358,892 | −26.5% | 1,106 |
| Suna | 3,400 | 1,745 | −48.7% | 2,422 |
| Dark Skeletal Shark Mask | 15,276 | 6,784 | −55.6% | 2,593 |
Two patterns hold across both windows. The Prestige tier is deflating — Prestige World Ender, Prestige Firework Lancer and Prestige Fruitbag are all down over 30 and 90 days — while the mid-tier accessories and the top cosmetic sets are up. Hover Pod, Coyote Outfit, Hollow's World Ender and Dark Blade rise in both windows, which is what a trend looks like as opposed to a spike.
When GPO trades
Raw posts-per-week from our corpus measures our collection, not the market. The ten channels did not start together: one runs from 22 July, two more join on 27 August, two on 29 August, one on 1 September and four on 4 September, so week-on-week totals across the whole window are not comparable. Every channel's first and last collected day is in the stats file. The like-for-like series is a fixed panel — the two channels that were collected every day of the same window.
| Day | Trade posts |
|---|---|
| Tue 1 Sep | 5,990 |
| Wed 2 Sep | 6,208 |
| Thu 3 Sep | 5,656 |
| Fri 4 Sep | 6,287 |
| Sat 5 Sep | 8,500 |
| Sun 6 Sep | 9,443 |
| Mon 7 Sep | 7,835 |
Weekend days average 8,972 posts against 6,395 on weekdays — 40% more trading on Saturday and Sunday. If you are pricing an item off "what it went for", the day of the week you sampled is part of the answer.
Why two GPO value lists never agree
This is the most useful thing in the dataset and it needs no comparison to anybody else's numbers. Our own solver produces a value per item per observation window — 12 hours, 48 hours, 7 days, 30 days — from the same trades. Across the 133 items with at least three reliable windows, the median spread between the highest and lowest window value is 4.5%. For the top of the distribution it is far worse:
| Item | Spread between windows |
|---|---|
| Megalodon Teeth | 72.5% |
| Kaido | 72.2% |
| Prestige Maid Outfit | 50.8% |
| Gura | 49.2% |
| Prestige Cupid's Chakram | 47.4% |
| Mochi Trident | 44.9% |
| Yuki | 44.1% |
Separately, of the 74 items with a full 90-day daily series, 26 move by more than 5% a day at the median. For those items a single published "value" is a snapshot of noise regardless of who publishes it.
So when two trackers disagree by a third on the same item on the same day, the usual explanation is not that one of them is lying. It is that one is reading a 12-hour window and the other a 30-day one, on an item whose real spread is 40%. The fix is not a better opinion; it is publishing the observation count and the window alongside the number, which is what this report does.
Method, and what this report cannot tell you
- Source. Public GPO trading channels. A record is a trade post — a player stating what they offer and what they want — parsed into canonical item names. It is an intention to trade, not a settled transaction; GPO does not publish a transaction log to anyone.
- Counting. "Appearances" counts posts, so an item listed twice in one post counts once. "Offered" and "wanted" count sides, so their sum can exceed appearances.
- Values. Solved by the same engine that runs gpovalues.com, anchored on Mythical Fruit Chest = 10,000, with a ±10% band on most items.
- Coverage. The corpus is not a continuous panel over the full 49 days — channel coverage per day is in the stats file. Use the fixed panel for any volume comparison.
- Bots and spam. No wash-trade filter is applied to the counts in this report. Repeated shop-style posts from one account inflate appearance counts for the items in those posts.
- Not in here. Real-money prices, competitor values, and anything about who is trading. We publish item counts, not people.
The data
- CSV, 148 items: gpo-trading-report-2026-09.csv — appearances, offered, wanted, solved value, confidence band, trade count, demand label, 30- and 90-day change, price points, daily noise, and whether the item qualified as a mover.
- Charts: the three SVGs on this page are free to embed with attribution.
- Every figure is regenerated by one script, which reads the corpus, the solver output and the price history and writes this page's CSV, charts and stats file. It runs monthly.

Where to buy the items in this report
We sell some of what is above. Availability changes daily, so check the page rather than this sentence:
- Venom, Soul, Mochi, Buddha, Tori and Pteranodon are fruits we list, priced from their trade value and how fast each one sells.
- The full fruit shelf is at GPO fruits; everything we stock for the game is on the Grand Piece Online hub.
The items we sell are delivered by in-game trade — your order page gives you a private server code for a Trade Hub room, our delivery bot joins you there and sends the trade for you to accept, and a staff member completes it if the bot can't. Every completed order has photo proof. Our delivery statistics are published live on /about rather than printed here where they would go stale.
If you only want the value and not the purchase, gpovalues.com publishes this same solve, re-run hourly, for free and with no signup.
