“Shark Tank” investor Kevin O’Leary has shared a wealth philosophy centered on liquidity, arguing that entrepreneurs should prioritize accessible cash over simply accumulating assets. O’Leary said he does not consider someone truly wealthy until they have at least $5 million in liquid cash, separate from the value of homes, cars or collectibles. His reasoning is that liquidity creates flexibility. Once an entrepreneur has enough cash available, O’Leary believes they can take bigger risks, start new businesses and recover more easily if a venture fails. He has also argued that founders should be willing to sell their businesses when a serious buyer appears, even if the offer is not the absolute highest price they might eventually receive. According to O’Leary, entrepreneurs can usually negotiate for somewhat better terms, but holding out indefinitely can mean missing an opportunity to convert years of work into liquid capital. He sees the entrepreneur, not any single company, as the more valuable asset. His view is that someone who successfully built one business can often use the proceeds and experience to build another. O’Leary has said not every company will succeed, and that entrepreneurship is ultimately a portfolio of risks. In his view, a few major wins can be enough to create lasting financial security. The broader principle is simple: assets can create wealth on paper, but liquidity gives entrepreneurs the freedom to act when the next opportunity appears.

"Shark Tank" investor Kevin O'Leary thinks critics attacking data centers over water use are aiming at the wrong target. Speaking on the "Money Rehab" podcast in July, O'Leary questioned the claims outright. "So, where did this claim come from that data centers use up so much water that it's like the entire water table of a state is going to go down 10 feet? All these ridiculous claims," he said. Then he brought golf into it. "Do you know what uses more water than many data centers? A golf course. Why aren't we shutting all the golf courses down?" His argument is that older comparisons no longer hold. "The modern-day data center today does not use water like the ones from 20 years ago," he said. Older facilities relied more heavily on evaporative cooling, while newer systems use closed loops. "Like your car radiator. You use the same water to cool the chips. So you're not using more water than that." He also noted that turbines once dependent on water can now be air-cooled, with batteries, solar and wind in the power mix. O'Leary framed the business itself as property. "Data center development is actually real estate. That's what it is," he said, comparing it to the climate-controlled storage facilities he once built and leased for pharmaceutical companies. His broader position was blunt. "We need more power. Period. The end."
