Coinbase is now the second-largest Bitcoin holder in the world after Satoshi Nakamoto, but the 982,000 BTC it controls does not belong to Coinbase. Nearly 1 in every 20 Bitcoin in circulation is now sitting inside Coinbase’s custody system.
TLDR
- Arkham Intelligence confirms Coinbase custodies approximately 982,000 BTC, making it the largest on-chain institutional entity after Satoshi Nakamoto
- Michael Saylor’s Strategy holds 738,000 BTC as direct corporate treasury, but only 443,000 BTC is on-chain visible due to Fidelity’s omnibus custody structure
- BlackRock’s IBIT fund holds approximately 775,000 BTC through Coinbase Prime, placing it third in institutional volume and narrowing the gap with Strategy
- Coinbase’s custody footprint now covers approximately 5% of the total circulating Bitcoin supply, concentrating exchange-level systemic exposure at scale
- Bitcoin ownership and Bitcoin custody are diverging structurally, and on-chain rankings do not reflect beneficial ownership
Arkham Intelligence released its updated Bitcoin rich list on March 28, 2026. The verified on-chain data places Coinbase second globally, behind only Satoshi Nakamoto, with approximately 982,000 BTC under its custody infrastructure.
Arkham’s data shows Coinbase accounts for approximately 5% of Bitcoin’s total circulating supply across its custody platform. No public company, ETF issuer, or sovereign government holds a larger verified on-chain position.
Michael Saylor’s Strategy, which has executed the most systematic corporate Bitcoin accumulation program of any public company, does not rank in the top two. Its on-chain verified position stands at 443,000 BTC.
The Distinction That Changes the Entire Narrative
Coinbase’s 982,000 BTC is not a corporate asset. It is held in a fiduciary capacity on behalf of retail users, institutional clients, and ETF issuers, including BlackRock and Grayscale.
Coinbase’s own corporate treasury holds a separate position of 14,548 BTC. Its primary custody infrastructure operates as the settlement and storage layer for client assets, maintaining high-velocity operational capacity to service institutional inflow and outflow demand.
Strategy operates under a direct ownership model. Its 738,000 BTC is a balance sheet asset acquired through market purchases and reported through SEC filings. Every Bitcoin Strategy holds is owned outright by the company, not held on behalf of third parties.
Strategy expanded its custody model to include Fidelity alongside Coinbase. Fidelity’s omnibus structure aggregates client holdings into pooled on-chain addresses, which reduces the external wallet-level visibility that analysts previously used to independently verify Strategy’s full position in real time.
The gap between Strategy’s total reported position of 738,000 BTC and its on-chain visible position of 443,000 BTC is a custody accounting outcome, not a discrepancy in company disclosures.
Full Bitcoin Holdings Ranking: Arkham Intelligence, March 2026
| Rank | Entity | BTC Holdings | Category |
|---|---|---|---|
| 1 | Satoshi Nakamoto | 1,096,358 | Individual |
| 2 | Coinbase | ~982,000 | Exchange Custodian |
| 3 | BlackRock (IBIT) | ~775,000 | ETF Issuer |
| 4 | Binance | ~655,000 | Exchange Custodian |
| 5 | Fidelity Custody | ~460,000 | ETF/Institutional Custodian |
| 6 | Strategy (on-chain) | ~443,000 | Corporate Treasury |
| 7 | U.S. Government | ~328,372 | Sovereign (Seizure) |
| 8 | Grayscale | ~218,000 | ETF Issuer |
| 9 | Tether | ~96,369 | Private Company |
| 10 | SpaceX | ~8,285 | Private Company |
Grayscale’s approximately 218,000 BTC is custodied entirely through Coinbase. BlackRock’s IBIT holdings are custodied through Coinbase Prime. Both positions are embedded within Coinbase’s 982,000 BTC on-chain total, not counted separately from it.
Why This Matters
Exchange custody is concentrating Bitcoin supply at institutional scale. Coinbase’s 982,000 BTC represents approximately one in every twenty Bitcoin in circulation, sitting under a single operational infrastructure. That level of concentration carries systemic implications if Coinbase faces a regulatory, operational, or security event.
BlackRock’s ETF inflows are reducing liquid Bitcoin supply. BlackRock’s IBIT has achieved the fastest asset growth in ETF history and now represents approximately 3.8% of total Bitcoin in circulation. Institutional inflows route through Coinbase Prime custody, removing BTC from open market availability. This directly reduces the volume of Bitcoin accessible to secondary market participants and retail allocators.
On-chain rankings do not reflect beneficial ownership. Arkham’s data measures on-chain attribution, not corporate ownership. A reader interpreting the list at face value concludes that Coinbase owns more Bitcoin than Strategy. The accurate reading is that Coinbase controls more Bitcoin in a fiduciary capacity, while Strategy owns more Bitcoin as a direct balance sheet asset than any on-chain figure in Arkham’s table reflects.
The data highlights a growing structural shift where Bitcoin ownership and Bitcoin custody are diverging at scale.
BlackRock’s Narrowing Gap With Strategy
BlackRock’s IBIT fund holds approximately 775,000 BTC, placing it third on Arkham’s verified list above both Binance and Fidelity Custody.
BlackRock’s position has narrowed to within approximately 23,000 BTC of Strategy’s total reported holdings. At current ETF inflow rates, that gap closes with each successive trading week.
BlackRock’s position is custodied through Coinbase Prime and is therefore embedded within Coinbase’s on-chain total. The two entities do not hold independent on-chain positions in Arkham’s ranking methodology.
Satoshi Nakamoto: 1,096,358 BTC, Zero Outbound Activity Since 2010
Every institutional entry on Arkham’s rich list ranks below a position that has not moved in over 15 years.
Satoshi Nakamoto’s holdings span more than 21,900 distinct wallet addresses, identified and attributed through the Patoshi mining pattern. None of these addresses have recorded outbound transactions since mid-2010. The position carries an approximate market value of $77 billion at current prices.
On February 7, 2026, an anonymous transfer of 2.565 BTC was sent to the original Genesis block address. The 50 BTC Genesis block reward is unspendable by Bitcoin protocol design. Analysts classify the inbound transfer as symbolic, with no evidence connecting it to activity from the original holder.
Nakamoto’s 1,096,358 BTC exceeds the combined on-chain verified positions of Strategy, the U.S. government, Grayscale, Tether, and SpaceX.
U.S. Government: 328,372 BTC From Criminal Asset Seizures
The United States government holds approximately 328,000 BTC sourced entirely from criminal asset seizures across multiple federal enforcement operations. A single FBI-managed wallet linked to the 2016 Bitfinex hack recovery accounts for approximately 95,000 BTC of that total.
The U.S. position ranks seventh globally on Arkham’s verified list, below every major exchange custodian and ETF issuer by a material margin.
How to Read Arkham’s Rankings Accurately
Arkham Intelligence uses on-chain forensics and proprietary wallet clustering to attribute addresses to entities. Exchange custodians rank consistently above corporate treasuries in this framework because they aggregate assets from millions of accounts into a single attributable on-chain footprint.
Strategy’s adoption of Fidelity’s omnibus custody model improves counterparty redundancy and satisfies institutional due diligence standards, but it reduces the real-time on-chain interpretability that external analysts previously relied on to verify the company’s solvency profile independently.
Strategy’s SEC-reported total of 738,000 BTC and its Arkham-verified on-chain position of 443,000 BTC are not contradictory figures. They reflect two different measurement frameworks applied to the same underlying asset.
The data highlights a growing structural shift where Bitcoin ownership and Bitcoin custody are diverging at scale. As institutional custody consolidates through platforms like Coinbase and Fidelity, on-chain rankings will increasingly underrepresent the true ownership distribution of Bitcoin across corporate balance sheets.
