Bitcoin Volatility Now Within S&P 500 Ranks, Grayscale Says

Bitcoin volatility has narrowed enough to sit inside the distribution of S&P 500 constituents, according to a Grayscale research note, challenging the view that the digital asset is always a far riskier holding than large-cap equities.

Grayscale said the cryptocurrency’s realized volatility fell to 43% over the past year, down from 64% on average over the past decade and 81% five years ago. The firm’s head of research, Zach Pandl, linked the decline to deeper liquidity, broader institutional participation and more regulated access venues. He said the question for investors has shifted from whether to hold a volatile asset to how to size the allocation.

How Bitcoin volatility compares to S&P 500 stocks

The report said Bitcoin is now less volatile than 19% of S&P 500 constituents, meaning a meaningful number of large-cap stocks show wider price swings. Data from K33 Research also pointed to 2025 as the least volatile year for the asset so far.

The findings follow a strong August and September for Bitcoin, when its price rose and several analysts described the move as a return to a bull market. The asset still remains well below its record high, recently trading around $82,485, after a 2026 drawdown of more than 50% from the previous October peak.
