Selling at the marketplace

Facts checked 1 Nov 2026

Selling turns spare materials into SWAY in your own wallet. In the Training Ground you sell at the Academy's own marketplaces, and the SWAY you earn is yours to keep when your hire ends.

Two ways to sell

• Market Sell: Sell straight into the buy orders already waiting at a marketplace, at the prices those buyers offer. The sale happens at once, and the goods then travel by hopper to the buyer.
• Limit Sell: Name your own price. Your goods wait at the marketplace until someone buys them, which may take a while, or never happen.

Tutor crews can only Market Sell at the Academy's marketplaces. A sell order pays whoever is in charge of the crew when it's filled, which after your hire could be the next student, so selling into buy orders keeps every sale yours.

The Academy's marketplaces

• Academy Market 2 (Lot 3,327): Kept for tutor crews: only they can sell here. It trades what students make, and the Academy posts buy orders here for what students make, right up to the warehouse materials at the end of the Training Ground. Anyone can buy here, and it's where you buy Sulfuric Acid and Core Drills.
• Academy Market 1 (Lot 3,149): Open to everyone. This is where you buy Food and Graphite, along with building components.
• A Small Fee, and Why Merchants Matter: Academy Market 2 charges a 1% fee whenever you sell into a buy order or buy from a sell order. A crew with a Merchant, like Academy Teachers, pays just that 1%. A crew with no Merchant pays double: 2%. Watch the fee on the screen before you confirm, and you'll see what a Merchant is worth. Academy Market 1 charges no fee at the moment.

Know what to keep

Everything you extract in the Training Ground has a job to do: the courses ahead turn it into the materials for one warehouse, and that takes about 8,900 tonnes of Olivine, 5,400 tonnes of Carbon Dioxide, 1,000 tonnes of Water, and 270 tonnes of Calcite. Keep those. Sell only what you have over, and the by-products the later courses will give you.

Sell into a buy order

1. Select Academy Market 2 and find the product you want to sell. The marketplace lists the buy orders waiting for it, best price first.
2. Choose Market Sell.
3. Choose your crew's warehouse as the place the goods come from, and how much to sell. Check the price and the total you'll receive.
4. Confirm, and approve in your wallet.

Your crew doesn't need to be ready, just on Adalia Academy. To sell several things at once, select them in your warehouse's inventory and choose Market Sell Selected.

Where the SWAY goes

Straight to your own wallet, the moment the sale goes through. It stays there when your hire ends: unlike the crew's warehouse, your SWAY never passes to the next student.
