The pop icon released the record as a farewell to fans, dying of liver cancer two days after its launch.
Blackstar becomes the fastest-selling album of 2016 as well as Bowie’s tenth number one album, with combined sales of 150,000.
Even before his death, Bowie was well on course for the top spot, wiping out competition from Adele and Elvis Presley.
Elvis’s If I Can Dream is forced to settle for two while Adele’s 25 loses its number one spot for the first time since its release, dropping two places to three.
Elsewhere, Justin Bieber’s Purpose slips a place to four while Bowie makes another appearance at five with his 2014 collection Nothing Has Changed.
It doesn’t stop there, as Bowie was streamed an astonishing 19 million times this week alone.
In fact, the late icon takes up almost one-quarter of the albums chart, with 19 of his albums and 13 of his singles entering the Top 100.
Among them are his Best of 1969/1974 collection, which clinches number 11, his 1971 album Hunky Dory (14) and his legendary record The Rise and Fall of Ziggy Stardust (17).
‘Heroes’ is the highest-charting Bowie single at 11, while ‘Life on Mars’ (16), ‘Starman’ (18) and ‘Let’s Dance’ (23) also make appearances.
Bowie’s monopoly of the charts is a reflection of his incredible contribution to music, which spanned five decades.
