We want to be the most transparent marketplace in the hobby. Here's every safeguard behind each auction on Alt.
We strive to be the most transparent marketplace in the hobby. When you bid on Alt, you should know exactly who you're up against, that every bidder is real, and that every sale actually closed.
Here's what we've built to make Alt the trading card auction site you can trust with every bid.
How Alt Protects Every Sports Card Auction
👀 Bid History
See who is placing bids on every item in Alt Auctions. Every listing shows its full bid history, and you can view global bidder levels too. All bid history is anonymized per listing for bidder security.
✅ Buyer Verification
To unlock high-value bidding, we ask bidders to submit a fully refundable $3,000 deposit by wire or credit card. That means every high-end bidder is verified before they can push a price up. Learn more here.
🚫 Linked-Account Blocking
Bids are automatically blocked when a bidder shares a billing address or payment method with the seller or another bidder on the same listing. Our team also monitors bidding patterns around the clock under our Auction Integrity Policy.
📊 Payment Status
In Alt's market data, every auction sale shows its payment status in real time, from Payment Pending to Payment Processing to Sold. So when you check comps, you know which sales actually closed.
