What Is the WoW Auction House?

The World of Warcraft Auction House is the in-game marketplace where players post items for sale, browse listings by category, and complete trades without meeting face to face. Every realm runs its own Auction House — Retail commodities pool region-wide across the US or EU, while every Classic realm prices items independently per faction.

Booty Bay Broker tracks WoW Auction House prices across every supported realm and stores the full price history so trends, weekly rhythms, and listing-quantity shifts are visible in one place. The tracker covers four game versions on four dedicated dashboards:

Each dashboard exposes a search-and-browse table, category sidebar, per-item detail panels, and price / volume / distribution charts. The sections below tour the data pipeline behind each version, the advanced filters most readers don’t discover on their first pass, and a glossary of common Auction House terminology.

Reading an item’s price history

Every dashboard on Booty Bay Broker works as an auction house price tracker: search or browse by category, then open an item to see its current buyout, market value, average buyout, and listed quantity side by side. A single snapshot only tells you what something costs right now — the chart is what turns that into something useful, showing what an item has actually cost over the past 24 hours, 7 days, and 30 days.

That chart also plots listed quantity — the total auction-house supply captured at each snapshot — on a second axis, so a spike or dip can be read against how much of the item was actually listed at the time. Because the tracker stores every scan rather than only the latest one, price history keeps building the longer a realm has been tracked. The same tracker works identically across Retail, MoP Classic, TBC Anniversary, and Season of Discovery — only the underlying data source and collection cadence differ by version, covered in the sections below.

Tracking Classic Markets

Classic auction houses split by faction — Alliance and Horde each maintain a separate listings pool on every realm. The tracker keeps the two markets separate end to end: realm selection, charts, heatmap cells, and shopping cart all respect the faction toggle so you never see a blended Alliance/Horde number that doesn’t exist in game.

Data Pipeline

For MoP Classic and TBC Anniversary, data comes from the TradeSkillMaster (TSM) API — not the Blizzard Battle.net API. Blizzard does not publish a public auction-house endpoint for the Classic progression realms, so every price number you see in the Classic surfaces originates from TSM’s aggregated scan data. The Classic detail panels expose four price metrics side by side:

  • Minimum Buyout — the lowest active listing for the item on the selected realm/faction.
  • Market Value — TSM’s weighted statistic. It discards outliers on both tails, so one mispriced listing can’t swing the number.
  • Average Buyout — the arithmetic mean of all listings. Compare to Market Value to spot a thin market where one big listing skews the mean.
  • Listed Quantity — how many units are currently posted. Tiny numbers warn you the price may be noisy; high numbers signal liquidity.

Snapshot Timestamps

Each item page carries the exact snapshot timestamp for the number it shows, so how recent a price is stays explicit rather than assumed. A quiet realm can also scan more slowly than a busy one, because fewer TSM contributors play there.

Connected Realms

Blizzard links low-population servers into connected realm clusters; a single auction house serves the whole cluster. The realm selector auto-groups connected realms so picking any member realm shows cluster-wide data — you never need to search every connected partner individually.

Classic vs. Retail Data

The supported versions share one frontend but very different data sources — Retail from the Blizzard Battle.net API, the Classic versions from TSM. Every chart on the site labels its source, and the sections below describe how the pipelines differ.

Retail Commodities

Retail commodity items (herbs, ores, cloth, consumables, trade goods) are region-wide: one price pool for every US realm, another for every EU realm. The Retail surface reflects this — swapping between realms on a commodity page won’t change the numbers, because Blizzard serves the same data for every realm in the region. Non-commodity items (gear, recipes, mounts, pets) stay per-realm.

Classic Per-Realm / Per-Faction

Every Classic item on every realm on every faction is priced independently. The tracker respects this: the realm selector is mandatory, the faction toggle is mandatory, and switching either re-fetches the full price series. This is why Classic markets feel noisier than Retail commodities — you’re seeing two small markets per realm rather than one regional market per item type.

Source Badges

Every Classic item page shows a TSM badge near the price statistics. Retail pages show a Blizzard API badge. If you’re ever unsure which source is feeding a chart, the badge is the ground truth.

TBC Anniversary Coverage

TBC Anniversary data collects hourly from TSM, covering every scanned realm on both factions.

Common Items to Track

TBC’s profession system concentrates demand around a small set of raw materials: Primal Fire / Air / Water / Earth / Mana / Life / Shadow / Might, plus Primal Nether for high-end recipes. Herbalism mats (Terocone, Nightmare Vine, Fel Lotus) and Jewelcrafting rare gems round out the top list. The tracker’s category sidebar groups these under Trade Goods > Elemental and Trade Goods > Herb for quick access.

Cooldown-Driven Markets

Tailoring (Shadowcloth, Spellcloth, Primal Mooncloth), Alchemy transmutes (Primal Might, rare-gem transmutes), and Jewelcrafting daily cuts all lean on time-gated cooldowns. The Professions tab on the TBC AH page cross-references each recipe’s material cost against the crafted item’s current Market Value so you can compare selling raw vs. selling crafted without pulling out a calculator.

MoP Classic Coverage

Mists of Pandaria Classic data collects daily from TSM, so a MoP chart plots fewer points than an hourly edition. That is the schedule, not a gap in coverage.

Material Interdependencies

MoP’s crafting graph is the most interconnected of any supported version — a price change on Ghost Iron Ore ripples across Jewelcrafting (prospecting), Engineering, and Blacksmithing at once. Living Steel (Alchemist-crafted) feeds Blacksmithing, Leatherworking, and Tailoring’s top recipes. The tracker surfaces these chains through the Professions calculator on the MoP Classic AH page, which lets you walk a recipe tree and see which sub-step captures the most margin on the current realm/faction.

Season of Discovery Coverage

Season of Discovery runs a reworked Classic-era item pool — season-specific runes, recipes, and crafted gear the other editions never had — so its market has no direct equivalent elsewhere on the site. Data comes from the TradeSkillMaster (TSM) API about twice a day, covering every scanned realm on both factions.

Getting more out of the tools

Two of the controls do more than they look like they do. Pairing the item search with the Market Value column surfaces listings sitting well below an item’s weighted median, and the volume chart beside it tells you whether the item trades often enough for that gap to mean anything.

Every recipe on the Professions Calculator lists its materials at current prices, so a craft can be costed at each step instead of only at the end. Switching the realm selector on an item page refetches that item’s chart, which makes comparing your own realms a few seconds’ work — worth knowing even though nothing outside Retail’s commodity pool actually trades across realms.

Reading Market Signals

The WoW economy moves because individual players post and buy on the Auction House throughout the day. The chart views below surface common price patterns so the underlying movement is easier to read.

Undercutting Cascades

When one seller undercuts, others often pile in — the result is a sharp, steep decline on the 24-hour chart followed by a rapid recovery once the discounted inventory sells out. The tracker’s 24H view renders cascades as a V-shaped dip over a few hours, distinct from the flatter long-term trend line.

Anchoring

The last-seen price shapes what other players expect. When the 7-day chart has been flat at one level for a while, new listings at that price tend to sell faster than listings at other numbers. The flat segment of the 7-day chart surfaces this anchor price at a glance.

Pre-Event Demand

Holiday events, raid tier launches, and PvP season starts all concentrate demand on specific item sets. The tracker’s 30-day view shows the pre-event run-up as a rising slope in the days before the event starts.

Reset Rhythms

Weekly resets move consumable prices on a predictable cycle: materials bottom out over the weekend and peak Tuesday/Wednesday. The 7-day chart surfaces this cycle on a per-item basis so the pattern is visible before the data lands in weekly rollups.

Classic Data FAQ

Quick answers to the questions that come up most often about how Classic data is collected and displayed.

How does Classic AH data differ from Retail?

Retail data comes from the official Blizzard Battle.net API. MoP Classic, TBC Anniversary, and Season of Discovery all come from TSM instead, because Blizzard publishes no public auction-house endpoint for those realms. Each edition collects on its own schedule, and the source badge on every item page shows which pipeline fed the number you are looking at.

What are connected realms?

Connected realms are servers Blizzard has linked so they share the same auction house, guilds, and trade channels. The tracker detects connected groups automatically and shows cluster-wide data when you select any member realm — no need to add every partner manually.

What is TSM and how is the data collected?

TradeSkillMaster is the most-used auction-house addon for WoW. Players who install the TSM desktop app upload their in-game scan data; TSM aggregates those scans into per-realm statistics and exposes them via an API. The tracker queries that API on a schedule and stores every snapshot so the historical charts keep building over time.

Which Classic versions are supported?

MoP Classic, TBC Anniversary, and Season of Discovery each have dedicated pages with realm selection, faction filtering, category browsing, and full historical charts. Retail (currently the Midnight expansion) is supported on its own page. Additional Classic versions will be added as Blizzard announces them.

Why are Alliance and Horde prices different?

Classic auction houses are faction-split at the engine level — Alliance players only see Alliance listings, Horde players only see Horde listings. The two markets have independent supply, demand, and prices. The faction toggle lets you compare.

Auction House Glossary

Quick reference for terms used throughout the tracker and the wider WoW economy.

A – F

AH
Auction House — the in-game marketplace where players list items for sale.
Bid
Starting price of an auction. Buyers bid up; the highest bidder wins when the auction expires. Most Retail players ignore bids and use Buyout.
Buyout
Fixed price at which a buyer can instantly purchase an item without waiting for the auction to expire.
Commodity
A stackable trade good sold on Retail’s region-wide market pool. Classic versions have no commodity system.
Connected Realm
Two or more servers merged by Blizzard that share one auction house, guild list, and trade channel.
Deposit
Fee paid when listing an item. Refunded on sale, lost if the auction expires unsold.
Flip
Community term for the pattern of a single item being purchased and then re-listed at a higher price. Visible on the 24H chart as a short-duration dip followed by a new listing at the prior level.

G – M

Gold Cap
Maximum gold a single character can hold (currently 9,999,999g 99s 99c in Retail).
Listed Quantity
Total units of an item currently posted on the AH for the selected realm/faction.
Market Value
TSM’s weighted statistic that trims outliers. More stable than a plain average — a single mispriced listing cannot swing it.
Min Buyout
Lowest buyout among all active listings.
Median Buyout
Middle value when all listings are sorted from lowest to highest.

N – Z

Non-Commodity
Item sold per-realm rather than region-wide — gear, pets, mounts, toys, recipes.
Region
Geographic server grouping. Auction House pages cover the US and EU; the WoW Token tracker also covers Korea and Taiwan.
Reset
Community term for a rapid drop and rebound in the listed-quantity metric, where the lowest listings disappear and new listings appear at a higher price. Appears as a sharp dip + spike in Min Buyout on the 24H chart.
Snipe
Community term for a listing priced substantially below TSM’s Market Value. The tracker renders these as outliers on the price-distribution histogram; the Market Value column flags the deviation at a glance.
TSM (TradeSkillMaster)
Popular WoW addon and API that aggregates auction house scans. Data source for Classic versions on the tracker.
Undercut
Listing an item slightly below the current lowest listing so your auction sells first.
Wall
Large quantity of an item listed at one price. On the price-distribution histogram, walls appear as a tall bar at a single price bucket with the rest of the distribution clustered above it.
