A significant trend of institutional adoption of cryptocurrency assets, particularly through spot Bitcoin Exchange-Traded Funds (ETFs), is emerging, with several major investment entities disclosing substantial holdings and strategic shifts in their portfolios. Leading this charge, Abu Dhabi’s sovereign wealth fund, Mubadala Investment Company, has notably increased its stake in BlackRock’s iShares Bitcoin Trust (IBIT).

Mubadala reported owning 12.7 million shares of IBIT, valued at approximately $630.6 million, as of December 31. This represents a substantial 46% surge from its previously disclosed 8.7 million IBIT shares as of September 30. Mubadala, which manages a vast global portfolio exceeding USD 330 billion in assets, focuses on generating sustainable returns for the Government of Abu Dhabi and supporting economic diversification beyond its traditional oil-based economy. Complementing this, Abu Dhabi-based Al Warda Investments also bolstered its IBIT holdings to 8.22 million shares in Q4 2025, an increase from 7.96 million in Q3 of the same year. As a part of the Abu Dhabi Investment Council under Mubadala, Al Warda’s allocation to a public Bitcoin ETF is particularly significant, given its historical preference for private investments. Collectively, Abu Dhabi investment vehicles held over 20 million shares of BlackRock’s IBIT at the close of last year, with a combined value surpassing $1.1 billion, underscoring a regional strategic pivot towards digital assets.

Beyond Abu Dhabi, other prominent investment firms are also accumulating significant Bitcoin exposure via IBIT. Jane Street notably boosted its IBIT holdings by 7,105,206 shares in Q4 2025, bringing its total stake to an impressive 20,315,780 shares, valued at $790 million. Similarly, BlackRock itself and Morgan Stanley each increased their IBIT positions by more than 2.37 million shares. Goldman Sachs, a firm previously known for its skepticism toward Bitcoin, has now disclosed approximately $2.36 billion in total crypto exposure, which includes a substantial $1.1 billion position in IBIT. This marks a clear shift in its stance, reflecting a growing acceptance of cryptocurrencies in mainstream finance. Goldman Sachs's diverse crypto portfolio also includes smaller holdings in Fidelity’s BTC fund, various bitcoin-related companies, options positions tied to IBIT, and exposure to other significant cryptocurrencies such as Ethereum, XRP, and Solana, as detailed in recent SEC filings.

The embrace of Bitcoin ETFs is not confined to institutional finance, extending to governmental and academic spheres. In a pioneering move, Texas became the first U.S. state to acquire Bitcoin for its Strategic Reserve in November of last year. The state purchased $5 million worth of IBIT shares, with the acquisition price per Bitcoin approximately $87,000, while simultaneously finalizing plans for the self-custody of this asset. This follows earlier explorations by Texas into legislation aimed at establishing a strategic Bitcoin reserve without utilizing taxpayer funds. Even academic endowments are adjusting their digital asset strategies; Harvard, in Q4 2025, modified its crypto holdings by cutting its Bitcoin position by 21% to 5.35 million IBIT shares, valued at $265.8 million, while concurrently establishing a new $86.8 million stake in BlackRock’s iShares Ethereum Trust. These widespread actions from sovereign wealth funds, major financial institutions, government entities, and academic endowments collectively highlight a burgeoning institutional confidence and diversified interest in the cryptocurrency market, particularly in regulated investment vehicles like spot Bitcoin and Ethereum ETFs.
