While Dunwall has a small black market organization, on which Piero Joplin and Daud's Whalers sold items for coin in 1837, the system in Serkonos is the envy of the Dunwall underworld, and Hatters can be overheard bemoaning the lack of a similar organization in Dunwall. By the time the protagonist returns to Dunwall in the mission Death to the Empress, at least one such store exists in Dunwall, a continuation of the Serkonan branch.
The exorbitant prices caused by the Duke's tariffs has played a large part in the rise of these shops, whose own steep prices are excused when compared to the price for buying the items through legal channels, if they are one of the few items which can be purchased that way.
Black market shops can be found all over Karnaca, including at the Campo Seta Dockyards, the Aventa District, the Dust District, the Palace District and Cyria Gardens. One has also been set up in the Black Pony Pub in the Tower District by the time the protagonist returns there. There are also some shops in Cullero. While the shopkeepers pay off members of the Grand Guard to avoid being shut down, and pay protection money to the Howlers to keep themselves safe, the shops still have to be set up in rather out-of-the-way locations. The symbol of two hands indicates the presence of a black market shop.
Black market shops sell products that fall into two categories: upgrades and gear.
In Dishonored 2, upgrades either allow black market shops to sell new kinds of ammunition, improve the ammunition that black market shops sell (and the ammunition found around the world), and improve the equipment that the protagonist has, increasing their carry capacity, making them take less damage and the like. For a complete list of upgrades, along with their requirements and prices, see here.
All black market shops in the game sell certain items, listed below. Some shops also sell other items which are generally only useful at that time.

During the events of Dishonored 2, every black market shop can be entered and robbed through various ways. If the shop owner spots the protagonist, they will close the store, and thus the only way to purchase upgrades. Ammunition and other valuable items, sometimes including bone charms and runes, can still be collected.
Campo Seta Dockyards
This store is entered by the back door. The key to this door can be found in the bloodfly-infested apartment located near the store. Note that Mindy Blanchard will become hostile if she notices the protagonist attacking the shopkeeper.
After bypassing the locked apartment gate through the abandoned apartment above the shop and accessing the basement, two burglars can be overheard discussing a plot to blow up the back wall, but are lacking the required third whale oil tank. The protagonist can either find a third whale oil tank and detonate the explosion, or toss a grenade. Either of these will blow a hole in the wall, allowing access to the store. Caution must be observed if attempting a nonlethal run; the explosion of all three tanks can kill the merchant inside the shop. Detonating each tank one by one can prevent killing her.
A crank wheel can be found just outside the store, and needs to be taken to the nearby river gate to open it, allowing access to a chain leading to a trapdoor. This trapdoor can be opened by shooting a link from a window grille next to the store. Climbing the chain gets the protagonist into the store.
This shop is accessed by a code taken from a calendar in the apartment above the shop, accessible by breaking the wooden barrier blocking the door from an outside window. The code is the date (Day/Month) of the couple's marriage, the month provided by the note next to the silvergraph of the couple, and the day being the only date highlighted that month on the calendar near the door.
The shopkeeper here opens the door himself, when provided with the appropriate code phrase. After stealing the note carried by a woman behind the shop, the phrase can be found by listening to an audiograph found in a boat being used to smuggle supplies to the store, at the dock near the beginning of the mission where two workers chatting next to it. If the boat has been raided, it will instead be on a desk in a small apartment occupied by the Grand Guard, with training mannequins on the balcony, near the wall of light blocking the entrance to the Grand Palace. The code must be given to the shopkeeper from the shop's back door, and the woman behind the shop (or her unconscious body) must be present.
Out the back of the Dunwall Courier office is a key, its general location vaguely hinted at in the note Warehouse Key, found under the locked door to the basement of the Black Pony Pub. Opening this door allows the protagonist access to a hole in the black market shop's floor, and thus the store itself.
- Purchasing anything at a black market store only gives the customer one of that item, with no limit to how many times it can be bought. Robbing the shop and collecting the items gives the usual amount, but only once.
- The exceptions to this are runes and other unique items, both of which can only be obtained once.
- The rewire tool is not available in the black market shop at the Campo Seta Dockyards, but is at every shop after that.
- There is no rune available at the black market shop in the Dust or Palace Districts.
- The shops can also be shut if the owner witnesses hostile action taking place outside their store, or if the owner is possessed. In the case of the latter, they will open the shop up again.
- Mesmerize will not shut the store, and upgrades and gear can still be purchased while the owner is mesmerized.
- Entering a black market shop grants the special action Black Market Heist for that mission.
- The code for the black market shop in the Palace District is "Serkonan Wine is Better Than Tyvian Prisons". However, this cannot be used without having found the code in the mission.
- If Emily or Corvo rob more than one black market shop, the Howlers set up an ambush outside the store in the Palace District to try and capture the protagonist.
- This locks the achievement Songs of Serkonos, as the third and final musical pair would otherwise be set up in this area.
- While fixed in an update, there was originally a mistake where, if the protagonist returned to the black market shop in the Palace District after entering the next map, Disabled Carriage Rails would no longer be available for purchase, but could instead be found on the shop floor. It still functioned as advertised if picked up.
- On top of this, the grenades would move to the right hand side of the store, and selecting them caused the background to display a nearby building instead. Furthermore, there were no grenades in the store if it was robbed.
- The store at the Campo Seto Dockyards is run by Horatio Weatherby, the store in Cyria Gardens is run by a man with initials M.V., the store in the Dust District is run by Martha, the store in the Palace District is run by Ricardo Marletto and the store in the Tower District is run by Geraldina.
- If the protagonist delivers the Roseburrow Prototype to the shopkeeper at Cyria Gardens, the shopkeepers in Karnaca will gives them a 15% discount on gear thereafter. This only occurs if the protagonist has not been seen robbing any shops earlier.
