'25' has already sold at least 2.433 million in slightly more than three days.

It’s confirmed. Adele’s 25 has broken the single-week U.S. album sales record, according to Nielsen Music.

After processing the first sales reports from Monday, Nov. 23, the album has already sold at least 2,433,000 in pure album sales in slightly more than three days. That sum beats the single-week record for an album since Nielsen began tracking sales in 1991, set by *NSYNC’s No Strings Attached, when it debuted with 2,416,000 in the week ending March 26, 2000.

Nielsen Music began tracking point-of-sale music purchases in 1991. Prior to 1991, there was no authoritative music sales tracking service in the U.S. and thus, it was mostly unknown how many copies of an album or song/single were sold in a single week.

25 was released on Nov. 20 through XL/Columbia Records. Yesterday (Nov. 23), Nielsen reported that 25 had sold at least 2.3 million copies in its first three days of release (through Nov. 22).

With more than three days left in the sales tracking week (as it ends at the close of business on Thursday, Nov. 26), the sales figure for 25 will grow larger. Presently, industry forecasters suggest the album could finish the week with 2.9 million sold. Billboard is scheduled to report 25's debut week sales on Sunday, Nov. 29, once Nielsen has finished processing its weekly data.
