Citi and Raiffeisen Bank International expand Strategy stakes as Bitcoin proxy buys grow

Citi lifted its holding to 961,554 shares after a 238,538-share purchase, while RBI raised its stake 3,080% to 5,980 shares; SEB and Swedbank disclosures add to signs banks are using Strategy for indirect Bitcoin exposure.

Fact Check
Both specific claims are confirmed by the caller-supplied primary sources and independently corroborated. The Citi article and Bloomingbit both state the 238,538-share purchase bringing total to 961,554 shares (~$90.5M), matching web search corroboration from Binance Square and Odaily. The RBI article states the 3,080% increase to 5,980 shares (~$554K), matching Odaily and bitcointreasuries.net. The characterization of banks using Strategy for indirect/regulated Bitcoin exposure is explicitly supported in both cryptobriefing articles. Sources are financial-news outlets reporting on 13F-type disclosures rather than direct SEC filings, which slightly tempers authority, but the consistency across multiple independent outlets is strong.
Summary

Citi increased its position in Strategy, the Bitcoin treasury company formerly known as MicroStrategy, by 238,538 shares and now holds 961,554 shares valued at about $90.5 million. Raiffeisen Bank International also raised its holding, lifting its stake 3,080% to 5,980 shares worth about $554,000 in a May 2026 13F filing. New disclosures show SEB Asset Management AB now holds 53,837 Strategy shares worth approximately $5.28 million after a roughly 1% increase, while Swedbank AB reported 90,590 shares. Strategy, which the new source says holds more than 800,000 BTC in its corporate treasury, has become a listed route for institutions seeking Bitcoin exposure without direct custody, though the stock also carries corporate execution and debt-related risks alongside amplified sensitivity to Bitcoin moves.
