In a bold move that challenges the norms of corporate crypto transparency, blockchain intelligence firm Arkham has publicly identified an additional 70,816 Bitcoin (BTC) linked to MicroStrategy—now rebranded as Strategy. This revelation brings the total volume of tracked Bitcoin holdings attributed to the company to 525,047 BTC, valued at approximately $54.5 billion as of mid-2025.
The disclosure intensifies the ongoing debate between on-chain transparency and digital asset privacy, especially in light of Executive Chairman Michael Saylor’s long-standing opposition to revealing wallet addresses. While Saylor has consistently argued that publishing proof-of-reserves exposes firms to cyber threats, Arkham’s advanced analytics suggest otherwise—demonstrating how on-chain sleuthing can uncover even the most guarded crypto positions.
Uncovering the Hidden: 87.5% of MicroStrategy’s BTC Now Tracked
Arkham’s latest findings confirm that 87.5% of MicroStrategy’s total Bitcoin holdings are now identifiable on the blockchain. The newly tagged BTC are spread across wallets previously unassociated with the company, indicating they may be managed outside of well-known custodians like Fidelity Digital Assets and Coinbase Prime.
“SAYLOR SAID HE WOULD NEVER REVEAL HIS ADDRESSES … SO WE DID”

This statement, posted by Arkham on May 28, 2025, underscores the firm’s mission: to bring transparency to institutional crypto activity through data-driven analysis. By applying proprietary heuristics and behavioral clustering models, Arkham successfully connected seemingly isolated addresses to MicroStrategy’s broader on-chain footprint—even without direct disclosure from the company.

While platforms like Bitcoin Treasuries report MicroStrategy’s holdings at 580,250 BTC based on official purchase disclosures, Arkham’s figure of 525,047 BTC reflects only on-chain-verified assets. The discrepancy arises from differing methodologies:
- Bitcoin Treasuries relies on public filings and corporate announcements.
- Arkham uses real-time blockchain monitoring, transaction clustering, and custodial pattern recognition to attribute ownership.
Despite not achieving full alignment, both sources show strong correlation—validating Arkham’s approach while acknowledging the limitations posed by custodial complexity and internal treasury strategies.
How Arkham Tracks Institutional Bitcoin Movements
Arkham doesn’t depend on self-reported data. Instead, it analyzes transaction patterns, input clustering, change address behavior, and known custodial fingerprints to map digital asset flows. In MicroStrategy’s case, Arkham previously linked over 107,000 BTC held in Fidelity’s omnibus custody pool to more than 327,000 BTC in segregated accounts—including those managed by Coinbase Prime.
Even though Fidelity does not publicly disclose individual client wallets within its custody structure, Arkham leveraged metadata and timing correlations to isolate transactions consistent with MicroStrategy’s known activity patterns. These techniques fall under entity clustering, a core method in blockchain forensics used by regulators and analytics firms alike.
This growing capability raises critical questions about privacy in enterprise crypto adoption. If sophisticated firms can de-anonymize major holders, what does that mean for companies betting on Bitcoin as a long-term treasury reserve?
The Privacy vs. Transparency Debate: Saylor’s Stance Under Fire
Michael Saylor has been one of the loudest voices against proof-of-reserves (PoR) disclosures that involve publishing wallet addresses. He argues such transparency introduces unacceptable security risks.
“No institutional-grade security analyst would think that publishing wallets is a great idea,” Saylor stated in a 2025 interview.
His concern centers on attack surface expansion: revealing cold storage locations—even indirectly—could make high-value targets more vulnerable to social engineering, insider threats, or coordinated cyberattacks. History supports this worry—crypto exchanges like Coinbase have faced breaches and ransom demands tied to insider leaks.
Yet critics argue that true financial integrity requires verifiable transparency. With over half a million BTC on its balance sheet, MicroStrategy influences market dynamics significantly. Investors and stakeholders may benefit from independent verification of holdings—without compromising security.

A Middle Ground? Zero-Knowledge Proofs Enter the Conversation
Enter zero-knowledge proofs (ZKPs)—a cryptographic innovation allowing entities to prove ownership or solvency without revealing underlying data.
Using ZKPs, MicroStrategy could theoretically demonstrate it controls a specific amount of BTC by generating a mathematical proof validated on-chain—while keeping all wallet addresses private. This balances accountability with operational security.
Interest in ZKP-based solutions is rising among institutional players. As regulatory scrutiny increases and investor demand for trustless verification grows, such technologies may become standard for publicly traded crypto treasuries.
Beyond MicroStrategy: Arkham’s Broader Mission
The MicroStrategy expose is part of Arkham’s larger initiative to demystify powerful actors in the crypto ecosystem. The platform recently launched its Key Opinion Leader (KOL) Label, which identifies and tracks wallets belonging to influential figures with over 100,000 followers on X (formerly Twitter).
This feature goes beyond simple identification—it reveals:
- Trading behavior
- Timing of asset movements relative to public statements
- Potential conflicts of interest in promotional content
For example, if a crypto influencer promotes a meme coin shortly before selling their position, Arkham’s system flags this activity—offering users deeper insight into market manipulation risks.
Such tools empower retail investors with institutional-grade intelligence—democratizing access to information once reserved for hedge funds and compliance teams.

Frequently Asked Questions (FAQ)
Q: How much Bitcoin does MicroStrategy actually own?
A: As of Q2 2025, MicroStrategy reports owning approximately 580,250 BTC based on public disclosures. Arkham has verified 525,047 BTC on-chain, representing about 87.5% of the total.
Q: Can Arkham be wrong about wallet ownership?
A: While Arkham uses advanced heuristics, attribution isn’t foolproof. False positives can occur due to shared custodial infrastructure or similar transaction patterns. However, repeated behavioral consistency increases confidence in identification.
Q: Why doesn’t MicroStrategy reveal its wallet addresses?
A: Michael Saylor argues that doing so increases cybersecurity risks by exposing cold storage locations. He believes alternative methods like zero-knowledge proofs offer safer verification paths.
Q: What is proof-of-reserves (PoR), and why is it controversial?
A: PoR is a method for proving asset ownership. Traditional PoR involves publishing wallet addresses and balances—raising concerns about privacy and security. Critics advocate for cryptographically secure alternatives.
Q: How do zero-knowledge proofs help with transparency?
A: ZKPs allow a party to prove they control certain assets without revealing which wallets or private keys are involved. This enables trustless verification while preserving privacy—an ideal solution for large-scale Bitcoin holders.
Q: Is Arkham tracking other companies besides MicroStrategy?
A: Yes. Arkham monitors numerous public companies holding Bitcoin—including Tesla, Coinbase, and Block Inc.—as well as key influencers and trading entities across major blockchains.
As blockchain technology matures, the tension between privacy and transparency will continue shaping corporate strategy. The clash between Michael Saylor’s secrecy doctrine and Arkham’s open-data ethos exemplifies this pivotal moment in digital finance evolution—a moment where data transparency meets cryptographic defense, and where every transaction tells a story.
