Sweden's largest online broker keeps a small but steady MSTR position, a quiet example of Bitcoin exposure through stocks
Sweden’s Avanza Bank reports holding 2,122 shares of Strategy, the Bitcoin treasury company many investors still know as MicroStrategy. The position is valued at $298K.
Avanza does not let customers buy Bitcoin directly, yet its fund arm owns a slice of the largest corporate Bitcoin holder anywhere.
The stake sits with Avanza Fonder AB , the bank’s fund management subsidiary. It shows up in 13F filings, the quarterly holdings reports that large investment managers submit to US regulators.
The share count has held around 2,100 shares, with the latest disclosure putting it at 2,122. The most recent report, dated June 30, 2026, confirmed the holding had not meaningfully changed.
The dollar value, on the other hand, has been anything but steady. Across recent quarterly filings, the same block of shares has been worth anywhere from $185K to $312K.
The swings track the MSTR share price, not any buying or selling by Avanza. Filings show the stake was valued at $312K in Q4 2025 and $265K in Q1 2026, with the share count unchanged throughout.
Avanza is one of Sweden’s leading online brokers, serving more than 2 million customers. On its platform, the company is listed as “Strategy A.”

The bank draws a firm line on crypto. Customers cannot trade Bitcoin directly through Avanza. Instead, the platform offers Bitcoin-related exchange-traded products, which package price exposure into something that trades like a regular security.
The company began life as a business intelligence software firm. Over the past several years it has reinvented itself as a corporate Bitcoin vault, buying the asset aggressively and repeatedly. Its holdings have now passed 848,000 BTC, according to recent company updates.
Plenty of banks and fund managers remain cautious about holding crypto directly. Custody, regulatory treatment and operational risk all add friction. Equity in a Bitcoin treasury company sidesteps much of that, offering exposure through an instrument that slots neatly into existing portfolios.
There is a trade-off baked into that bridge. Owning Strategy is not the same as owning Bitcoin. Shareholders also take on company-specific factors: how management finances its purchases, how the market values the stock relative to its Bitcoin pile, and how sentiment toward the company itself shifts over time.
A position that moved between $185K and $312K without a single share changing hands is a reminder that proxy exposure can be bumpy.
For Swedish retail investors, Avanza’s setup offers two paths to Bitcoin exposure without direct ownership: exchange-traded products tied to the asset’s price, and shares in companies like Strategy.
A stable share count over multiple quarters suggests a hold-and-wait posture rather than an expanding conviction bet.
Strategy, meanwhile, keeps stacking. With its holdings now above 848,000 BTC, the company remains the default way for cautious institutions to dip a toe into Bitcoin.
