Practicallly everyone's album sales doubled to tripled last year compared with the years before.
If that trend keeps up, then yes, there's a chance.
At the moment the most likely candidates would be TWICE or IZ*One, but I wouldn't be surprised if a dark horse pops up that will get the 1M sales threshold next (after TWICE and IZ*One, ITZY, RV, Aespa or Baby Monster would seem most likely).
