UBWI estimates Bitcoin's share of total global wealth using directly observed national balance sheets where available and a versioned residual model for economies without comparable published balance sheets.

Total Global Wealth

$584.30T

Observed national balance sheets, plus the modelled residual, plus Bitcoin.

Bitcoin market capitalization

$1.56T

Scheduled issuance of 20,084,612.50 BTC, derived from the Bitcoin subsidy schedule through block 967,075, priced at the Chainlink BTC/USD reference price on Ethereum mainnet.

Bitcoin supply

20,084,612.50 BTC

Protocol-derived scheduled issuance through block 967,075, inclusive (halving era 4, 3.125 BTC per block). Cumulative block subsidy scheduled by the Bitcoin protocol through this block height, inclusive. Transaction fees are excluded and no lost-coin or spendability adjustment is applied, so this is scheduled issuance rather than an externally reported circulating-supply figure.

Directly observed

60.1 %

18 rights-cleared national balance sheets, 53.0 % of world GDP.

Modelled

39.7 %

A versioned residual model for economies that publish no comparable balance sheet. Modelled wealth, not observed wealth.

Sensitivity range

0.2224 – 0.2919 %

The span of four named assumptions about the wealth-to-GDP ratio of the unobserved world. Not a confidence interval.
