Shark Tankinvestor Kevin O'Learyhas drawn a hard line on what it means to be truly wealthy. It has nothing to do with property, cars or business equity. The Canadian entrepreneur says the real threshold is $5 million (approximately £3.95 million) in liquid cash — a sum he calls his 'magic number' and one he keeps parked in US Treasury bills.

'You're not rich until you have $5 million liquid. Not in your house. Not in your car. Cash,' O'Leary wrote in an April 2026 post on X. 'Once you have that, you can take risks again.'

Kevin O'Leary says all you really need in the bank to be secure for the rest of your life is $5 Million."The discipline is, get $5 Million and put it in Treasury Bills and don't touch it"."I have T-bills, I roll a lot of T-bills and that's my f*ck you account and it always...pic.twitter.com/v7B6WPUw88

The strategy is a version of what personal finance circles call an 'F-you account' — a pool of money large enough that work becomes optional. O'Leary has pushed this argument across YouTube, X,Fox Business, and LinkedIn over the past three years, anchoring it each time to the same figure.

O'Leary's logic works backwards from passive income. At a 6 to 7 per cent annual return, $5 million generates between $300,000 and $350,000 (£237,000 to £277,000) a year before tax — well above the median US household income of $74,580 (£58,900).

'When you make that, you have to set that aside, and you don't risk it,' O'Leary said in a 2023 YouTube video. 'Then after that, you can start to take risk capital and put it to work.'

He told Fox Business' Varney & Co. in early 2026 that he keeps at least $5 million in T-bills — short-term US government debt that can be converted to cash almost immediately. At current yields near 4 to 5 per cent, that reserve generates roughly $250,000 (£198,000) a year pretax, asFast Companynoted.

'You have a family of four, and poo-poo hits the fan in your world, and everybody loses their job, you can sustain a family on 250 pretax,' he told the outlet. 'That's why it's the magic number.'

'You're not rich if it's all tied up in real estate, you're not rich if it's in jewellery and in cars and in boats and all that stuff,' O'Leary told Fox Business.
