Key Takeaways
- • Norway's Government Pension Fund Global (NBIM), the world's largest sovereign wealth fund with over $2 trillion in assets, increased its indirect bitcoin exposure by 149% in 2025 to 9,573 BTC, valued at approximately $837 million USD (8.5 billion NOK).
- • Strategy accounts for 86% of NBIM's indirect bitcoin exposure, with significant additional holdings in MARA, Metaplanet, Coinbase, and Block—all firms actively accumulating bitcoin treasuries rather than the fund acquiring BTC directly.
- • Despite the substantial growth in BTC holdings, NBIM's weighting of indirect bitcoin exposure remains unchanged at just under 0.04% of total fund assets, suggesting deliberate portfolio positioning rather than passive accumulation.
- • K33 Research calculates NBIM's bitcoin exposure by multiplying the percentage of bitcoin-holding firms' shares held by the fund by those companies' respective bitcoin treasuries, providing a transparent methodology for tracking indirect crypto exposure among institutional investors.
Summary
Norway's sovereign wealth fund has dramatically expanded its indirect bitcoin exposure, growing its position by 149% during 2025 to reach 9,573 BTC, according to analysis from K33 Research. While the Government Pension Fund Global—managed by Norges Bank Investment Management (NBIM) under the Ministry of Finance's direction—has not directly purchased bitcoin, its substantial equity positions in bitcoin-holding companies have created meaningful cryptocurrency exposure. The fund's indirect BTC holdings were valued at approximately $837 million USD at year-end 2025, measured in Norwegian krone terms at 8.5 billion NOK.
The concentration of this exposure is notable, with Strategy accounting for 86% of NBIM's total indirect bitcoin exposure. Additional significant holdings include positions in MARA (Marathon Digital), Metaplanet, Coinbase, and Block—all firms maintaining active bitcoin treasury strategies. K33 Head of Research Vetle Lunde noted that these companies have "continued to stockpile bitcoins," creating a leveraged bitcoin exposure mechanism for the Norwegian fund through equity ownership rather than direct cryptocurrency acquisition.
A critical observation from K33's analysis indicates that despite the 149% year-over-year growth in absolute BTC holdings, NBIM's weighting of indirect bitcoin exposure has remained essentially flat at just under 0.04% of the fund's total assets across the past two reporting periods. Lunde characterized this stability as "a somewhat deliberate weighting in this exposure," suggesting that while the fund has benefited from the growth of its bitcoin-holding portfolio companies, it has not intentionally increased its strategic allocation to cryptocurrency-related assets relative to its broader $2 trillion portfolio. The Norwegian fund, which invests in approximately 1.5% of the world's listed companies across global equities, bonds, and real estate, continues to treat bitcoin exposure as a modest peripheral position despite its substantial absolute magnitude.
