Grant Cardone is a lot of things—real estate investor, entrepreneur, father, and a man who has built a career on telling people exactly how he sees it, no filter included. His social media is a steady stream of motivational clips, money talks, and blunt advice aimed at anyone willing to listen. Love him or not, the man has opinions, and he’s not shy about sharing them.
In a TikTok posted to his account, Cardone took aim at one of the most sacred rules in personal finance: diversification.
“Rich people do not diversify,” he said. “The wealthiest people on this planet, when they went into trains, they went all in on their trains. Cardone continued with more examples. “When Henry Ford went into cars, he didn’t diversify—he went all in on cars,” he said. “Elon Musk, he’s going all in on solar, right? That’s how you make hits.”

Then came the other side of the coin: “But the middle class is taught what? A little here, a little here, put a little here, put 27 different things out there. Why? Who benefits from 27 investments? Wall Street. Start early, get an IRA—who benefits? Wall Street.”
There’s a real thread worth pulling here. The financial industry does collect fees on every fund, every account, every rebalance. When someone tells you to split your money 27 ways, it’s fair to ask who’s really winning in that arrangement. And yes, the biggest fortunes in history were built by people who bet heavily on what they knew best.

Going All In Meets Real Life
But context matters. For every Ford or Musk, there are countless entrepreneurs who went all in on a single idea and lost everything. You don’t hear those stories because nobody’s posting them. That’s survivorship bias at work—we celebrate the winners and forget the wreckage. Diversification may not build empires, but it has quietly built a lot of comfortable retirements.
Cardone’s message is built for motivation, and there’s value in that confidence. But when it comes to your actual money, the best strategy is one built around your life—not someone else’s TikTok.
