What Is a Tradeline Marketplace?
A tradeline marketplace connects two sides of the same transaction: buyers looking to add a well-established authorized-user account to their credit file, and cardholders willing to offer an AU slot on their own card in exchange for payment. Instead of relying on informal, one-on-one arrangements, a marketplace centralizes verification, pricing, and payment through one platform — with escrow sitting between both sides.
Navigating it well comes down to a few real factors: account age, credit limit, utilization, and which bureaus a given card actually reports to. Not every listing serves the same goal, so matching a tradeline to what you're actually trying to accomplish matters more than picking the first available option. For an independent explanation of how tradelines work, see Experian's guide.
How a Transaction Actually Moves
The same core sequence, regardless of which side you're on.
1. Match
Buyers filter by limit, age, and bureau. Sellers get matched by card profile.
2. Verify
Both the listing and the buyer's identity are checked before anything proceeds.
3. Escrow Holds Funds
Payment moves into escrow, not directly to the cardholder, before posting happens.
4. AU Added
The cardholder adds the buyer directly through their own issuer.
5. Confirmed & Released
Once posting is confirmed, escrow releases payment to the cardholder.
Escrow works by holding funds in a neutral account until an agreed condition is met — here, that condition is confirmed posting, not just the buyer clicking "purchase."
For Buyers
- Filter by credit limit, age, price, and bureau reporting
- Funds held in escrow until posting is confirmed, not released upfront
- Dashboard access to track status and expiration in real time
For Cardholders
- Set your own availability — you control which slots are listed and when
- Get paid once posting is confirmed, not before
- Add and remove authorized users yourself, directly through your issuer
What Escrow Does and Doesn't Cover
Escrow protects the payment itself — funds aren't released to the cardholder until posting is confirmed, and buyers aren't charged for a listing that never reports. It doesn't eliminate every risk in the process:
- Card issuers can close or flag an account at their own discretion, which can affect an in-progress listing
- No tradeline, however well-vetted, guarantees a specific credit score change — results depend on the buyer's full credit profile
- Posting timing varies by issuer and bureau, and isn't something either side fully controls

Frequently Asked Questions
What is a tradeline marketplace?
A platform where buyers can purchase authorized-user tradelines and cardholders can offer AU slots on their own cards for payment, with escrow sitting between both sides of the transaction.
How do I know if a tradeline will post on time?
Posting timelines vary by bank and reporting cycle. See our Authorized User Tradeline Timeline page for how to plan around this.
Are AU tradelines legal?
Authorized-user status itself is an ordinary, everyday practice — banks support it for family members routinely. Paid, commercial tradeline arrangements between unrelated parties are a well-established part of the credit industry, though the space carries real regulatory attention; we structure our process around verification, transparency, and consent for exactly that reason. See Are AU Tradelines Legal? for more detail.
What makes a tradeline "seasoned," and why does it matter?
A seasoned tradeline is one open and in good standing for years — these typically carry more weight with scoring models than newer accounts. See What Makes a Tradeline Seasoned for detail.
