Corporate Bitcoin reserves have surged to 1.91 million BTC, accounting for 9.5% of the cryptocurrency's circulating supply, following a significant accumulation of 23,000 BTC in January 2025. This increase, reported by blockchain intelligence firm Santora, underscores growing institutional confidence in Bitcoin as a long-term asset. The January addition marks one of the largest monthly increases since 2023, with corporate holdings now valued at over $95 billion. The trend of corporate Bitcoin accumulation began with MicroStrategy's strategy in 2020 and has since been adopted by numerous companies seeking diversification and a hedge against inflation. This strategic move aligns with broader institutional adoption trends and is supported by evolving regulatory frameworks, such as the FASB's 2024 accounting standards and the EU's MiCA regulation. As corporate Bitcoin reserves grow, they are expected to influence market dynamics by reducing circulating supply and potentially increasing volatility during periods of high demand.
