Buffett’s Vanguard S&P 500 fund outperformed hedge‑fund picks, earning 7.1% annual vs 2.2% and delivering $854k vs $220k after a decade.
Warren Buffett’s $1 million wager that a low‑cost S&P 500 index fund would beat a basket of hedge funds ended in a decisive win, with the Vanguard Admiral fund returning 7.1% per year ($854,000) versus the hedge‑fund portfolio’s 2.2% ($220,000) over the ten‑year span [1].

The challenge began on Jan 1 2008, when Buffett and Protégé Partners each put $500,000 into zero‑coupon Treasury bonds slated to mature at $1 million in 2018. After the 2008 crash drove bond values near $1 million, the parties swapped the bonds for Berkshire B‑shares, which rose to $1.4 million by Feb 2015 [1]. The index fund, Vanguard’s S&P 500 Admiral (expense ratio 0.04%), then outperformed the hedge‑fund average from 2009‑2014, pulling ahead in cumulative return by 2014 and widening the gap in 2016 with an 11.9% gain versus 0.9% for Protégé [1].
Buffett argued that the “two‑and‑twenty” fee structure of hedge funds erodes returns, a point echoed by Bloomberg’s Ted Seides, who noted that fees matter “no doubt” [1]. The Vanguard fund’s 0.04% expense ratio meant virtually all market gains were retained, while the hedge‑fund picks suffered from higher fees and, according to Seides, a lack of global diversification that hurt their performance relative to the MSCI All‑Country World Index [1].
The bet’s outcome reinforces a long‑standing body of research showing passive index funds routinely beat active managers after fees are accounted for [2]. Buffett estimated that “financial elites” wasted over $100 billion by shunning low‑cost index funds, a claim that underscores the potential fiscal impact on pension plans and taxpayers [1].
Buffett’s victory highlights that, over a decade, the simple, low‑cost approach of an S&P 500 index fund can generate substantially higher net returns than a curated selection of hedge funds, raising questions about the future role of high‑fee active managers in institutional portfolios.

Buffett argues that the S&P 500, comprising the largest and most stable U.S. companies, offers a resilient long‑term investment that is likely to recover from market crashes.
