Arsenal fans protested in their thousands outside the Emirates Stadium last Friday against the club’s ownership.
Ek tweeted after the protest his desire to buy the club he has supported since he was young.
The Swede is reportedly worth around £3.4billion, with Arsenal valued at roughly £2b by Forbes.
Speaking on Tuesday, Swedish financial journalist Johan Wendel claimed Ek would not have gone this far if he did not think he could afford to buy the north London club.
Wendel told Sky Sports News: “Well it all comes down to what the Kroenkes are asking for, of course, but I don’t think Daniel Ek would make a tweet like that, a comment like that, if he hadn’t thought of the financial considerations.
