ARK Invest CEO Cathie Wood stated in their 2026 outlook report that Bitcoin will become an effective diversification tool for investment portfolios in the coming years.
Wood emphasized that Bitcoin’s low correlation with traditional asset classes like gold, stocks, and bonds offers investors the potential for higher returns per unit of risk.
An analysis conducted by ARK Invest based on weekly returns between January 2020 and early January 2026 reveals Bitcoin’s portfolio diversification power. According to the data, the correlation coefficient between Bitcoin and gold is only 0.14.
This ratio is quite low compared to the 0.27 correlation between the S&P 500 index and bonds. While Bitcoin’s correlation with bonds is measured at its lowest level at 0.06, its correlation with the S&P 500 is at its highest level at 0.28, but it is still limited compared to the relationships between traditional asset classes.
Cathie Wood stated that Bitcoin’s long-term value proposition is fundamentally based on its supply structure. She explained that the Bitcoin protocol strictly limits supply growth, predicting that the annual rate of increase in new Bitcoin supply will be approximately 0.8% over the next two years, after which it will decline to around 0.4%. She emphasized that this mathematically determined and predictable supply structure gives Bitcoin a natural scarcity.
According to Wood, the combination of limited and predictable supply and increasing global demand has allowed the price of Bitcoin to rise by approximately 360 percent since the end of 2022. The ARK Invest CEO stated that if these dynamics continue, Bitcoin could take on a more central role in portfolios for both institutional and individual investors.
