Everyone's favourite dinosaur (Saurian, actually) returns in Borderlands 4, once again running an under-the-table vendor machine that offers you legendary gear. While it works a little differently this time around, you'll still need to find Maurice's Black Market location each week.
If you're a Destiny 2 convert, then Maurice's vending machine is effectively Xur. Each week, the Black Market machine will spawn in a new location somewhere on Kairos, giving you access to top-tier loot in return for cash. With Borderlands 4 moving to a full open-world with Kairos, though, you'll have even more ground to cover to track his machine down.
Where is the Borderlands 4 Black Market location this week?

This week (May 14 to May 21) the Black Market vending machine in Borderlands 4 is located at the Shammy's Shack POI, on the wooden incline by the river. This is in the Coastal Bonescape area inside The Fadefields region.
Fast travel to The Stockroom silo fast travel point and simply glide southeast towards the river. Once you reach the river, look around for the wooden incline ramp—this leads you to the vending machine at the top. A pretty easy journey this week.
When does the Black Market reset?
Maurice's Black Market vending machine resets every Thursday at 9 am PT in Borderlands 4. Good luck with your rolls!
How does Maurice's Black Market work?
The biggest change to the weekly Black Market vending machine in Borderlands 4 is that the inventory on offer is unique to each player—it's no longer a fixed stock for every player. I guess it's more incentive to actually track him down to see if you have any god rolls, though it's not quite as fun as having everyone rush to his vending machine when his stock is revealed.
You can actually reset what your vending machine is selling just by backing out of the store, though it'll then go on a 30-minute cooldown, which you can track via the weekly activity icon on the map. This is an important detail to note if you're against the clock for the weekly reset.
Since each player has a different offering, it's worth checking with your friends to see what their version of Maurice's Black Market machine is selling, as it might just be the perfect item for you.
How to unlock the Black Market vending machine in Borderlands 4

Before you can start purchasing legendary gear from Maurice's Black Market machine, you have to beat the main campaign and the introductory Ultimate Vault Hunter Mode quest, Maurice's Bounty.
Once you've ticked off that quest, the Black Market vending machine becomes a weekly affair across the open world. The machine will appear almost invisible until you get close to it, though it'll also be marked on your map once you get near enough.
