We have received a few messages about this section of recently. Previously, this section showed the state of all bids placed directly through the CryptoPunksMarket contract. Typically, there were a handful of bids open at one time. Since we rolled out Collection Bids ( active bids has expanded dramatically, both in $ and absolute terms. This section is still showing Punks with valid bids. The reason there are more is because people can now assign the same balance in their contract to multiple Punks. For example, if you want to place an 80 ETH bid on a Hoodie Punk, you can deposit 80 ETH once and then place many individual or trait bids with that 80 ETH. The section is sorted high -> low, so the Punk in the top left has the highest currently active bid. Hope this helps.
