Instead, they rely on **institutional-grade third-party custodians**, with a clear shift toward diversification away from a single provider.<\/p>\n<div><\/div>\n<div>Here&#8217;s the best current guesstimate based on on-chain analytics (primarily from Arkham Intelligence), public transfers reported in late 2025, and consistent patterns:<\/div>\n<div><\/div>\n<div>&#8211; **Majority appears under Fidelity Digital Assets \/ Fidelity Custody** (the dominant share now). &nbsp;<\/div>\n<div>&nbsp; Strategy executed large transfers throughout late 2025 (e.g., ~58,390 BTC worth ~$5.1B in November 2025, plus additional ~11,642 BTC in early December 2025), moving coins from Coinbase to Fidelity. By late 2025, reports showed ~165,000\u2013177,000 BTC explicitly sent to Fidelity. Given continued accumulation and no major reported reversals, analysts estimate Fidelity now custodies the **largest portion** (likely 40\u201360%+ of the total stack, potentially 300,000\u2013450,000+ BTC). Fidelity uses an **omnibus custody model** (client assets are pooled\/mixed in shared cold storage addresses), so individual client attribution becomes harder on-chain once deposited\u2014much of Strategy&#8217;s BTC now shows up labeled under &#8220;Fidelity Custody&#8221; rather than a distinct Strategy entity.<\/div>\n<div><\/div>\n<div>&#8211; **Significant remaining portion still with Coinbase** (Coinbase Custody \/ Coinbase Prime). &nbsp;<\/div>\n<div>&nbsp; Earlier holdings (pre-2025 diversification) were heavily Coinbase-based (hundreds of thousands of BTC in segregated wallets). Even after the big moves to Fidelity, a substantial amount (~200,000\u2013300,000+ BTC) likely remains there, including segregated cold storage addresses that Arkham has historically tagged to Strategy.<\/div>\n<div><\/div>\n<div>&#8211; **Possibly smaller allocations elsewhere** (Anchorage Digital, others). &nbsp;<\/div>\n<div>&nbsp; Strategy has appeared at events with Anchorage reps discussing custody, and their Bitcoin-for-Corporations materials reference multiple custodians (Coinbase Custody, Anchorage, Fidelity). No massive transfers to Anchorage have been publicly flagged recently, so any allocation there is probably minor.<\/div>\n<div><\/div>\n<div>&#8211; **No meaningful self-custody \/ cold wallets under direct company control** that are publicly known or tagged. &nbsp;<\/div>\n<div>&nbsp; Michael Saylor and the company have consistently refused to publish wallet addresses, sign messages, or do traditional Proof-of-Reserves (citing security risks to the stack, custodians, and investors). Arkham Intelligence reverse-engineered and tagged ~87\u201392% of the holdings back in mid-2025 (mix of segregated Coinbase addresses + Fidelity omnibus inflows), but no new major self-custody revelation has occurred.<\/div>\n<div><\/div>\n<div>In summary: &nbsp;<\/div>\n<div>Rough split guess for the current ~709,715 BTC: &nbsp;<\/div>\n<div>&#8211; ~45\u201360%+ in **Fidelity Custody** (omnibus cold storage) &nbsp;<\/div>\n<div>&#8211; ~30\u201345% in **Coinbase Custody\/Prime** (segregated + possibly some omnibus) &nbsp;<\/div>\n<div>&#8211; Balance scattered across 1\u20132 other qualified custodians or legacy setups &nbsp;<\/div>\n<div><\/div>\n<p>it&#8217;s the consensus view from on-chain trackers like Arkham as of early 2026. The company emphasizes audited SEC filings, Big-4 audits, and institutional custodian agreements as the verifiable source of truth over on-chain transparency. If you&#8217;re trying to track it yourself, Arkham&#8217;s entity page for Strategy (or Fidelity Custody) is the closest public approximation available.<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>&nbsp; &nbsp; Michael Saylor \u2066\u202a@saylor\u202c\u2069 Strategy has acquired 22,305 BTC for ~$2.13 billion at ~$95,284 per bitcoin.
