Mentions of blockchain-related activity in US Securities and Exchange Commission filings surged throughout 2025, signalling rising institutional engagement with digital assets.
Data showed that SEC filings referencing blockchain topics reached approximately 8,000 mentions by August and remained elevated through November.
Bitcoin accounted for the largest share of the increase, dominating filing activity across the reporting period.
Analysts said the trend reflected growing institutional confidence following clearer regulatory guidance in the United States.
The surge was closely linked to the expansion of spot Bitcoin exchange-traded funds approved in early 2024.
Traditional asset managers continued to file amendments and new disclosures as they expanded Bitcoin-related investment products.
Bitcoin-related filings showed sustained momentum rather than the cyclical patterns seen in other crypto categories.
The legislation encouraged firms to formalise their digital asset strategies through proper registration.
Regulatory momentum continued in July with the passage of the Digital Asset Market Clarity Act.
