- • Bitcoin's one-year volatility stood at 43%, versus a 10-year average of 64% and 81% five years ago, according to Grayscale figures.
- • Grayscale head of research Zach Pandl said the institutional debate has shifted from whether to hold bitcoin to how to size its weighting in a portfolio.
- • K33 Research data showed 2025 was the least volatile year in bitcoin's history, which it attributed to broadening institutional channels following spot bitcoin ETF approvals in 2024.

Summary
Grayscale has reported that bitcoin's realised volatility has dropped into the distribution range of S&P 500 components, according to a report by Bitcoin Magazine on October 15, 2026. The asset manager said many large-cap stocks have shown larger price swings than bitcoin over the same period. Publisher context cited in related coverage placed bitcoin as less volatile than 33 S&P 500 stocks, and as recently as late 2023, 92 index members were more volatile than bitcoin.
Zach Pandl, head of research at Grayscale, said in a memo that bitcoin's price swings have narrowed significantly from early extremes as the asset matures through greater liquidity, increased institutional participation and broader regulated access channels. Grayscale's figures show bitcoin's one-year volatility at 43%, below its 10-year average of 64% and 81% five years earlier. Grayscale argued that investors already holding volatile equities may find bitcoin's price swings less burdensome than expected.
K33 Research said in data released last December that 2025 was the least volatile year in bitcoin's history. It attributed the shift to a broadening investor base and to institutional inflow channels widened by the approval of spot bitcoin exchange-traded funds in 2024, which it said partially eased trading shocks as liquidity deepened.
Market conditions also contributed. Bitcoin posted its strongest quarterly performance in recent years after a sharp rally in August and September, and some analysts referred to a return to a bull market. Reported backdrops to the rebound included news that the U.S. Treasury would expand buyback operations aimed at providing liquidity, and renewed interest in so-called debasement hedge trades amid a softer dollar.
The decline in volatility does not eliminate downside risk. Bitcoin fell more than 50% from its all-time high at one point in 2026, and although it later rebounded, recent prices of about $82,485 remained 35% below the $126,080 peak. Analysts characterize bitcoin as still highly price-sensitive, though the market is finding it harder to treat the asset as exceptionally unstable as it did in the past.
