Arkham Intelligence, a blockchain analytics firm, has sparked controversy by linking over $7.6 billion worth of Bitcoin to Strategy, the company formerly known as MicroStrategy. The revelation claims to have identified wallet addresses holding 70,816 BTC tied to Strategy, despite co-founder and executive chairman Michael Saylor’s staunch opposition to exposing wallet information.
“Saylor said he would never reveal his addresses. So, we did,” Arkham wrote in a statement. This bold move follows Saylor’s comments at Bitcoin 2025 in Las Vegas, where he emphasised the risks of transparency in wallet activity. According to Saylor, disclosing wallet addresses opens the door to transaction tracing, predictive analytics, and potential vulnerabilities. He even suggested using AI to simulate attack scenarios to highlight the risks of such disclosures.
While blockchain records are public, associating wallet addresses with specific owners often relies on speculative methods. This approach has drawn scrutiny, as Arkham’s wallet-labelling techniques have faced criticism for inaccuracies in the past, notably from Mantra CEO John Mullin, who denied the firm’s claims during a separate incident.
Strategy’s Bitcoin Holdings Valued at $54.5B
Arkham’s findings suggest that Strategy’s Bitcoin holdings are more extensive than previously thought. The analytics firm pegged the company’s total identified Bitcoin reserves at $54.5 billion, representing approximately 87.5% of its reported BTC holdings.
If accurate, this would place Strategy among the most prominent Bitcoin holders globally, further cementing its status as a major player in the cryptocurrency market. Despite this, the discovery raises questions about the company’s ability to maintain operational privacy and long-term security, a concern echoed by Saylor in his recent public appearances.
Slower Bitcoin Buys Reflect Strategic Shift
While Strategy remains the largest publicly traded Bitcoin holder, its acquisition pace has noticeably slowed. According to a report from K33 Research, the company purchased 4,020 BTC between May 19 and May 25 for $427.1 million. However, this represents a marked deceleration compared to earlier buying sprees, such as November’s frenzied accumulation.
Capital deployment from its $21 billion at-the-market (ATM) offering also decreased during the same week, with only $348.7 million allocated—down from $705.7 million the previous week and $1.31 billion earlier in May.
K33 Head of Research Vetle Lunde attributes this slowdown to two primary factors: a shrinking premium for MSTR shares relative to Bitcoin holdings and rising competition among corporations investing in cryptocurrency reserves.
Navigating Privacy and Publicity
Saylor’s concerns about transparency highlight a critical tension between blockchain’s public ledger nature and the privacy needs of institutional players. While public access to blockchain data ensures accountability and decentralisation, it also exposes vulnerabilities that may be exploited.
Arkham’s controversial disclosure underscores the challenges of balancing transparency and security in the cryptocurrency space. As blockchain analytics firms refine their methods, misidentification risks and potential reputational damage for targeted entities remain significant.
Future Prospects for Strategy
Despite these challenges, Strategy’s bullish stance on Bitcoin continues to set it apart. Jeff Walton, an analyst at Strategy, predicts that the company’s unprecedented Bitcoin exposure, which recently crossed $111,000 per BTC, positions it to become the top publicly traded company worldwide.
Whether or not these ambitious goals materialise, the interplay between privacy, transparency, and institutional adoption of Bitcoin is likely to remain a focal point in the evolving crypto landscape. As firms like Strategy navigate this complex terrain, the stakes for privacy-conscious strategies and innovative security measures have never been higher.
