Bitcoin Institutional Holdings Hit 4.11 Million BTC as Liquid Supply Shrinks

Institutional holdings of Bitcoin (BTC) have climbed to roughly 4.11 million BTC, underscoring how steadily shrinking liquid supply is becoming a defining feature of the current market structure—and a potential tailwind for longer-term price dynamics.

According to data compiled by BitcoinTreasuries as of Sunday, March 22 UTC (March 22 ET), institutions collectively hold 4,112,885 BTC across 344 entities. Over the past 30 days, total holdings rose 1.7%, while the number of holders remained largely unchanged—suggesting accumulation is being driven more by existing players adding to positions than by a surge of new institutional entrants.

Publicly listed companies account for 1,179,371 BTC, while ETFs and other funds hold 1,497,687 BTC. Governments control 650,298 BTC, private companies hold 288,014 BTC, DeFi and smart contract-related holdings total 383,468 BTC, and exchanges and custodians account for 114,047 BTC.

Across tracked institutional crypto reserves, Bitcoin remains overwhelmingly dominant, representing 95.1% of holdings. Ethereum (ETH) follows with 4.2%, while Solana (SOL) sits at 0.42%, XRP at 0.18%, and BNB at 0.13%—a distribution that highlights how institutional exposure is still concentrated in BTC despite broader market diversification.

Public companies: 1,179,371 BTC

Publicly listed firms now hold an estimated 1,179,371 BTC—worth about $80.6 billion—equivalent to roughly 5.616% of Bitcoin’s total supply tracked in the dataset. The past month saw public-company holdings rise by 3.5%, reflecting continued corporate appetite for BTC balance-sheet exposure.

Strategy ($MSTR) remains the single largest corporate holder, with 761,068 BTC—about 3.62% of total BTC supply—cementing its status as the most influential individual treasurer in the market. The company made three disclosed purchases this month, adding BTC on March 2 (3,015 BTC), March 9 (17,994 BTC), and March 16 (22,237 BTC).

Among other notable moves, Strive ($ASST) increased its holdings twice—adding 179.08 BTC on March 11 and 317 BTC on March 19—pushing it into the top 10 corporate holders. CleanSpark ($CLSK) slipped to 11th after selling 150 BTC earlier this month, a reminder that miner treasury management can still be opportunistic even amid broader institutional accumulation.

The top public-company holders include Strategy ($MSTR), MARA Holdings ($MARA), Twenty One Capital ($XXI), Metaplanet (MPJPY), Bitcoin Standard Treasury Company ($CEPO), Bullish ($BLSH), Riot Platforms ($RIOT), Coinbase Global ($COIN), Hut 8 Mining ($HUT), and Strive ($ASST).

In South Korea, five listed companies continue to report Bitcoin holdings with no recent changes in balances. Their global ranks generally slipped by one position, reflecting faster accumulation elsewhere. The firms include Bitmax ($377030), Bitplanet ($049470), Wemade ($112040), Parataxis Korea ($288330), and Neowiz Holdings ($042420).

Private companies: 288,014 BTC

Private companies collectively hold 288,014 BTC—valued at approximately $19.6 billion—representing about 1.371% of supply. Block.one remains the largest private holder with 164,000 BTC, followed by Tether Holdings with 96,184 BTC. Other notable holders include Stone Ridge Holdings Group (10,000 BTC), SpaceX (8,285 BTC), and the Tezos Foundation (2,903 BTC).

Governments: 650,298 BTC

Government-held Bitcoin totals 650,298 BTC—about $44.3 billion—roughly 3.097% of supply. The United States leads with 328,372 BTC, followed by China with 190,000 BTC and the United Kingdom with 61,245 BTC. Ukraine (46,351 BTC) and El Salvador (7,598 BTC) also rank among the largest state holders, with the United Arab Emirates (6,420 BTC) and Bhutan (5,425 BTC) next in line.

Market observers often view expanding government ownership as a signal of gradual institutional normalization. While motivations vary—from law enforcement seizures and asset management to strategic reserves—greater state involvement can reinforce perceptions of Bitcoin’s staying power as a globally recognized asset.

ETFs, funds, exchanges & custodians: 1,611,734 BTC

ETFs and major market intermediaries hold 1,611,734 BTC—approximately $109.9 billion—equivalent to about 7.675% of supply. BlackRock’s spot Bitcoin ETF, iShares Bitcoin Trust ($IBIT), remains the largest in this category with 786,329 BTC, representing roughly 3.744% of Bitcoin’s supply. The fund added to its holdings multiple times this month, including on March 3 (3,810 BTC), March 11 (9,630 BTC), and March 17 (8,458 BTC).

Other large ETF holdings include Fidelity Wise Origin Bitcoin Fund ($FBTC) with 187,813 BTC, Grayscale Bitcoin Trust ($GBTC) with 156,278 BTC, and Grayscale Bitcoin Mini Trust with 51,473 BTC, followed by ARK 21Shares Bitcoin ETF ($ARKB) at 45,245 BTC.

DeFi & smart contracts: 383,468 BTC

DeFi and smart contract-related BTC holdings amount to 383,468 BTC—around $26.2 billion—about 1.826% of supply. Wrapped Bitcoin (WBTC) remains the largest component at 125,330 BTC, followed by cbBTC at 87,668 BTC and BTCB at 65,301 BTC. Legacy and protocol-linked holdings such as Casascius coins (34,808 BTC) and Solv Protocol Bitcoin (12,755 BTC) also feature prominently.

Collectively, the data illustrates how Bitcoin is being absorbed through multiple channels: direct balance-sheet accumulation by public companies, private companies, and governments; and 'demand-response' custody vehicles such as ETFs, funds, exchanges, and DeFi smart contracts. With institutional and sovereign stacks trending higher, analysts say the resulting reduction in readily tradable supply can act as a structural support for the market over the medium to long term, even as near-term price action remains sensitive to liquidity cycles and macro conditions.
