Xbox One has sold 18 million units worldwide, according to information revealed by the CEO of eSports company Gfinity.

Discussing the launch of the company's new Tournament Build App on Xbox One, CEO Neville Upton revealed that the app would allow Gfinity "to reach Xbox One's 18 million users globally, offering this new larger audience the opportunity to interact with the Gfinity brand."

The figure puts Xbox One significantly behind PS4, which had sold 35.9m units as of January 3, 2016.

Microsoft has not officially announced sales figures since November 2014, when it revealed that Xbox One was approaching 10 million units shipped.

Gfinity's figure tallies with that hinted at by EA CFO Blake Jorgensen earlier this year, who estimated that PS4 and Xbox One had sold around 55 million units between them, putting Xbox One at around 19 million.

Microsoft is currently rumoured to be working on a successor to the Xbox One, with speculation pointing towards a reveal at E3 this June. Yesterday, Xbox chief Phil Spencer revealed that the company intends to talk about its plans for Xbox One, Windows 10 "and beyond" in the weeks and months ahead.

UPDATE:

UPDATE: Gfinity has contacted MCV to clarify that Upton's numbers are based on the previously referenced figures from January and not on official Microsoft data.

VGC has it at:

19.5m as of January 2nd
19.8m as of january 30th

His statement doesn't like something that should be taken as an official figure.

Wouldn't be shocked either way though.

if its true XOne is undertracked by half of million.

we know from gfk that Xbox is undertracked in france and in germany by 200k +

I always felt the X1 is overtracked here on VGchartz, the numbers dont suprise me if true

I'm confused by this. VGC has it at 20.7m. That looks 'overtracked' by over 2 million to me.

Good lorde at the overtracking. That's gotta be more than 2 million, vgchartz.

I imagine that's based off old info, possibly from when Microsoft touted 18m Win 10 enabled X1's, they were probably throwing that number around to devs to entice them to develop for the platform. I'm not sure Microsoft has given any further update since then.

this numbers were actual for end off jan (19 million)

Now we are at the end of april 3 more months away from this time point.  So 2 million in 3 months sounds possible to me.(Global) and every quarter we se from the gfk numbers (same then npd in the us) that it´s undertracked in germany  and in france by more than 200k combined. because of this i think Xone is at 21 million + at the moment

Wouldn't surprise me to see an article tomorrow saying the Xbox One has sold an estimated 25m and then another article next Wednesday saying its sold an estimated 13M.

HUGE overtracking if true.

If only Microsoft would reveal official numbers instead of silly figures like how many zombies have people killed in DR3, or how many miles in Forza, etc.
