Strategy (MSTR) added a major institutional backer this week. AIMCo, which manages roughly $142 billion in assets, picked up 1.38 million MSTR shares for approximately $219 million. It marks the Canadian pension fund’s first move into a Bitcoin treasury company.
MSTR gained 1.03% to $159.82 in Thursday’s premarket session following the news. The stock had dropped 4.54% the session prior, closing at $158.19 on Wednesday.
AIMCo isn’t the only institution building a position. Capital Group added 4.32 million MSTR shares last week through its American Funds Fundamental Investors fund, bringing its total stake to 10.33 million shares, worth around $1.63 billion.
Vanguard also quietly added to its position in April, purchasing over 1.2 million shares worth $195 million at the time. It now holds just over 2 million shares, currently valued at around $323 million through its VOE ETF.
Strategy’s latest Bitcoin purchase was notably smaller than the week before. The company added 3,273 BTC for $255 million, compared to 34,164 BTC worth $2.54 billion the previous week — a 91% drop in volume.
The slowdown came down to funding. Strategy used common stock sales this time rather than its preferred STRC stock, which limited how much capital it could deploy.
Despite the pullback in buying pace, confidence in Strategy’s hold strategy remains high. Polymarket currently puts just a 10% probability on the firm selling any Bitcoin before the end of 2026.
Strategy’s total Bitcoin holdings now stand at 818,334 BTC, acquired at a total cost of over $61.8 billion. That keeps it just ahead of BlackRock, which holds 810,077 BTC.
April was a turning point for MSTR. The stock closed the month at $165, up 33% — its first positive month after eight straight months of losses. From August 2025 to March 2026, the stock had fallen 75%.
Bitcoin also had a strong April, rising 12%, its best monthly performance since April 2025.
On the preferred stock side, Strategy held its STRC dividend at 11.5% for May, the third consecutive month at that rate. STRC’s April volume weighted average price came in at $99.76, close enough to its $100 par value to keep the rate steady.
STRC is currently trading at $99.75 and has been below par since April 15.
Strategy is also considering a move to semi-monthly dividend payments for STRC to further reduce price volatility.
Analysts on TipRanks rate MSTR as a Strong Buy, with an average price target of $283.33.
