Billionaire hedge fund manager Warren Buffett has long advocated for investing in the S&P 500, but recent statistics reveal that since 2020, this index has lagged behind Bitcoin by approximately 88%.
In a post on Oct. 5 on X, co-founder of stock market data newsletter Opening Bell Daily, Phil Rosen, pointed out that while the S&P 500 has increased by 106% in USD value since 2020, it has “collapsed” dramatically in BTC terms, much to the delight of Bitcoin enthusiasts.
The Standard and Poor’s 500, or S&P 500, is a stock market index that tracks the performance of 500 leading companies listed on U.S. stock exchanges.
Since its inception in 1957, the index has achieved an annual inflation-adjusted return of about 6.68%, typically exceeding the average inflation rate in the U.S.
This may explain why the renowned U.S. entrepreneur Warren Buffett has frequently endorsed the S&P 500 index as the ideal choice for average investors, and notably supports a 90/10 investment strategy — allocating 90% of a portfolio to the S&P 500 and 10% to short-term U.S. Treasury bonds.
S&P 500 breaks records, but so does Bitcoin
The S&P 500 continues to set new records in 2025, currently standing at $6,715.79, having climbed 14.43% since the beginning of the year.
Conversely, Bitcoin has surged 32% this year, recently reaching $125,000 for the first time.
In comparative terms, as reported by OfficialData.Org, a $100 investment in the S&P 500 from early 2020 would grow to around $209.85 by July 2025, while a $100 investment in Bitcoin would amount to $1,473.87.

Differences between Bitcoin and S&P 500
Nonetheless, comparing the two investments isn’t entirely equitable.
The S&P 500 serves as a comprehensive benchmark for the U.S. stock market, capturing the performance of the 500 largest public companies in the country, an index that is regularly updated and regarded as a lower-risk, lower-reward investment.
In contrast, Bitcoin is a unique digital asset guided by entirely different narratives — revolving around scarcity, decentralization, and deflation — which has seen tremendous adoption as investors seek innovative ways to enhance or preserve value.
Bitcoin is also relatively new, experiences greater day-to-day volatility, and has a substantially smaller market cap compared to the S&P 500, valued at $2.47 trillion versus a staggering $56.7 trillion.
