McGregor, 35, has become a successful whiskey connoisseur and pub owner in recent years, with the former venture adding millions of pounds to his bank balance.

The Irishman recently put himself on track to become a future combat sports prompter by becoming a shareholder in bare-knuckle boxing promotion BKFC.

But The Notorious’ investment in combat sports hasn’t stopped there.

The former two-weight UFC champion has recently become an investor in Alta Global Group, the parent company of Train Alta.

Train Alta is an online platform which provides both in-gym and online training to budding mixed martial artists around the world.

McGregor’s investment in Train Alta’s parent company comes as no surprise as the platform’s founder is none other than his head coach and mentor John Kavanagh.

It’s unclear how much McGregor has invested in the Alta Global Group, although the company’s recent filing of a 13G file with the USA’s Securities and Exchange Commission suggests it’s upwards of five per cent.

Alta Global Group CEO John Langton recently said of McGregor’s investment: “Conor offers huge value to us in terms of brand awareness, audience and obviously gym owner growth.”

McGregor is just a matter of weeks away from making his first octagon outing in nearly three years.

Mystic Mac will make his cage comeback on June 29 in the co-main event of UFC 303 in Las Vegas.

The Dubliner will be welcomed back to action by fellow fan favourite Michael Chandler – his rival coach on season 31 of The Ultimate Fighter.

McGregor’s desert dust-up with Chandler will be his first outing since he shattered his left leg in his trilogy fight with Dustin Poirier in July 2021.

And he plans to use his once-shattered limb to get back in the win column in emphatic fashion.

In a recent interview with James Corden, he said: “I am Terminator now.

“I have a titanium rod that goes into the knee and down to the bone, right down to my ankle.

“It’s unbreakable.

“I wish for and I will work on landing this kick – with this steel bar in my leg – against an opponent and getting them out of there.”
