Norges Bank Investment Management holds $400M in crypto assets through indirect exposure

Norway’s Government Pension Fund Global, the world’s largest sovereign wealth fund, holds hundreds of millions of dollars worth of Bitcoin exposure. Not because anyone in Oslo decided to buy crypto, but because the companies in its massive equity portfolio keep stacking sats on their own balance sheets.

Norges Bank Investment Management, the entity that runs the $1.7 trillion fund, has seen its indirect Bitcoin holdings balloon over the past several years. According to estimates from K33 Research, the fund’s exposure stood at roughly 3,821 BTC, valued at approximately $356.7 million, at the end of 2024. That represented a 153% year-over-year increase.

How a passive index fund accidentally became a Bitcoin whale

NBIM doesn’t buy Bitcoin directly. It buys equities. Lots of them, across thousands of companies worldwide, in a broadly passive investment strategy designed to capture global market returns.

The crypto exposure is a side effect. When companies like Strategy (formerly MicroStrategy), MARA Holdings, Coinbase, and Tesla load up their balance sheets with Bitcoin, any fund holding their stock inherits that exposure by default.

Since 2020, when NBIM’s indirect Bitcoin investment amounted to a modest 796 BTC, the figure has grown by more than an order of magnitude. By mid-2025, K33 Research projected the fund’s exposure had climbed to 7,161 BTC, worth roughly $844 million. By year-end 2025, that figure reached 9,573 BTC. And as of the first half of 2026, estimates put the total at an all-time high of 11,549 BTC, valued at approximately $676 million, or about 0.03% of NBIM’s total assets under management.

The numbers behind the growth

Strategy remains the single largest contributor to this dynamic. The company, which has transformed itself from a middling enterprise software firm into essentially a leveraged Bitcoin vehicle, holds the largest corporate Bitcoin treasury in the world. NBIM’s equity stake in Strategy alone accounts for a significant portion of its indirect crypto exposure.

MARA Holdings, one of the largest publicly traded Bitcoin miners, and Coinbase, the biggest US-based crypto exchange, round out the top contributors. Tesla, which has maintained Bitcoin on its balance sheet since early 2021, also plays a role.

It’s worth noting that NBIM itself does not publicly validate these calculations. The estimates come from external researchers analyzing publicly available 13F filings and ownership data. K33 Research, a Norwegian crypto analysis firm, has been tracking NBIM’s indirect exposure for several years and has become the primary source for these figures.

What it means for institutional crypto adoption

NBIM’s 0.03% allocation to Bitcoin, even at its peak, barely registers as a rounding error for a fund of this size.

The trend also raises questions about passive investing more broadly. Index funds and quasi-index strategies like NBIM’s are designed to be agnostic. They buy the market, full stop. But when the market itself starts holding Bitcoin, that agnosticism breaks down. Passive investors are making an implicit bet on Bitcoin whether they’ve considered it or not.

NBIM has shown some curiosity about the space beyond pure equity holdings. The fund hosted a podcast featuring Coinbase CEO Brian Armstrong, though the organization has been careful to note that such conversations don’t reflect investment strategy.
