Does Warren Buffett use Vanguard?

Warren Buffett’s Simple Advice: Look to Vanguard

Warren Buffett has long been a vocal advocate for low-cost, passive investing—and his endorsement of Vanguard fits perfectly with that philosophy. While Buffett doesn’t personally manage a typical portfolio like most investors, his advice to others has consistently pointed toward index funds, especially those offered by Vanguard.

During a past Berkshire Hathaway shareholder meeting, Buffett made headlines by specifically recommending the Vanguard S&P 500 ETF as an ideal choice for long-term investors. His reasoning is straightforward: the fund offers broad market exposure, ultra-low fees, and minimal turnover—three qualities Buffett has always praised. He’s famously advised that most people are better off avoiding stock-picking and instead investing in a low-cost index fund that mirrors the overall market.

Building on that logic, if Buffett were constructing his recommended 90% stocks / 10% bonds portfolio, the Vanguard 0-3 Month Treasury Bill ETF (VBIL) would likely be his go-to for the cash portion. It’s a safe, liquid, and highly efficient way to hold short-term U.S. government debt—exactly the kind of simple, reliable instrument he favors.

What makes Buffett’s endorsement powerful isn’t just the product, but the principle behind it: simplicity, discipline, and cost efficiency. He’s repeatedly said that after his passing, the money left to his wife’s trust should be invested 90% in a stock index fund like Vanguard’s S&P 500 offering and 10% in Treasury securities. That’s not just advice—it’s a blueprint.

So while Buffett may not “use” Vanguard in the traditional sense, his trust in its approach speaks volumes. For everyday investors, following that same path might be the smartest move they never overthink.
