Norway's sovereign wealth fund has disclosed an $81.9 million investment in BitMine Immersion Technologies, giving one of the world's largest institutional investors indirect exposure to Ethereum.

Norges Bank reported holding 6,151,062 BitMine shares valued at $81.87 million as of June 30. The position surfaced in the fund's latest holdings disclosure and constitutes an equity investment rather than a direct purchase of Ethereum.

BitMine's Expanding Ethereum Treasury

BitMine has scaled up its Ethereum treasury strategy rapidly in 2026. In August, the company reported holding 5.8 million ETH, equivalent to roughly 4.8% of Ethereum's total supply, with more than 5 million ETH already deployed into staking validators.

Through its so-called "Alchemy of 5%" strategy, BitMine aims to acquire 5% of Ethereum's circulating supply — an approach that has made it one of the largest publicly traded corporate holders of ETH. With roughly 4.8% of supply already reported, the company sits within a fraction of a percentage point of that goal, making its remaining accumulation one of the most concrete indicators to watch as the strategy matures.

The Norwegian fund's stake therefore offers exposure to BitMine's Ethereum strategy without requiring the fund itself to hold the cryptocurrency. It also ties the fund to the corporate digital-asset treasury model, in which publicly listed companies accumulate a cryptocurrency as a core balance-sheet asset.

Broader Institutional Footprint

The disclosure also underscores the growing presence of digital assets in institutional portfolios. Norway's Government Pension Fund Global manages approximately $2.3 trillion and holds positions across thousands of companies worldwide. At $81.87 million, the BitMine stake represents roughly 0.004% of the fund's assets, making the disclosure notable more for the exposure it reveals than for its weight in the portfolio.

BitMine did not appear among the fund's disclosed holdings in December 2025, indicating the position was likely built during the first half of 2026. Public filings do not specify exactly when the shares were acquired. Because the fund publishes its holdings, any change in the BitMine position would surface in subsequent disclosures, offering a filing-based view of institutional exposure to Ethereum treasury equities.

The investment comes as BitMine continues to position itself as an Ethereum-focused treasury company, combining ETH accumulation with staking to pursue additional returns on its cryptocurrency holdings.

For investors, Norway's disclosure may reinforce the trend of rising institutional acceptance of Ethereum-related equities. BitMine shares, however, remain exposed to cryptocurrency volatility as well as the risks tied to the company's concentrated treasury strategy.
