The studio back catalogue of the Liverpool four-piece is being reissued in full on September 9, with the albums available individually and in stereo and mono box sets.
Gennaro Castaldo at HMV told the Evening Standard: "We feel there's every chance that The Beatles will dominate the top 20 next week, even with only four days sales compared with other artists.
"Chances are Sgt Pepper and Abbey Road will battle it out for the No.1 spot against the current incumbents - the Arctic Monkeys."
He added: "All the albums being reissued next week will comfortably make the top 40, which will create a new record for the official charts."
The BBC will air number of programmes dedicated to The Beatles on BBC Two and BBC Four next week.
