Summary
In 2007, Warren Buffett entered a wager with Ted Seides, co-founder of Protégé Partners, pitting a passive index investment against a selection of professionally managed hedge fund vehicles over a ten-year period running from January 1, 2008 to December 31, 2017. Seides selected five fund-of-funds with indirect exposure to hundreds of hedge funds whose identities were not disclosed. Buffett chose the Vanguard 500 Index Fund Admiral. According to the account, the test was designed to determine whether active oversight justified its cost during real market stress.
The bet opened during the 2008 financial crisis, when the S&P 500 fell roughly 37% and the fund-of-funds posted significantly smaller losses, giving the active managers an early lead. That advantage reversed as markets recovered from 2009 onward. The combined fund-of-funds portfolio trailed the index in each of the remaining nine years, and by the end of 2017 the Vanguard fund had gained 125.8% cumulatively, leaving all five active portfolios well behind.
The article attributes the gap primarily to structural costs rather than manager error. Investors in fund-of-funds paid fees to the fund-of-funds managers on top of the fees charged by each underlying hedge fund. Buffett calculated that these layered fixed fees consumed roughly 2.5% of total assets annually, in addition to incentive fees tied to returns. Those charges applied regardless of whether the portfolios made or lost money. Buffett is quoted in the article as asking, “In the aggregate, do these investors get their money’s worth?”
The prize pool was structured as follows. Buffett and Protégé each contributed $318,250 to purchase zero-coupon U.S. Treasury bonds with an aggregate face value of $1,000,000 maturing at the end of the decade. By 2012, lower bond yields had made the Treasuries unattractive, so both parties agreed to replace them with 11,200 Class B shares of Berkshire Hathaway, with Buffett pledging to cover any shortfall against the $1,000,000 charity target. By December 31, 2017, the shares were worth $2,222,279, and the full proceeds went to Girls Inc. of Omaha.
The article is dated October 21, 2026, but it recounts a bet that concluded in December 2017. Its figures are historical context, and its general recommendation for low-cost index investing reflects the author's framing rather than new reporting.
