Realized Cap

Realized Cap (realized capitalization) is an on-chain valuation model that values each unit of bitcoin at the price it last moved on-chain, then sums those values across the entire circulating supply. Rather than multiplying the current spot price by total supply (the way conventional market capitalization works), it treats long-dormant coins as still being worth whatever they were worth when they last changed hands. The result approximates the aggregate cost basis of all coins, often described as the total realized capital deployed into the network.

How it is calculated

Every unspent transaction output (UTXO) carries a timestamp and a value. Realized Cap is computed by valuing each UTXO at the USD price prevailing when it was created, then aggregating across the whole UTXO set. Coins that have not moved since a much lower price contribute their old, lower valuation; recently transacted coins contribute near current prices. This makes the metric far less reactive to short-term price swings than market cap.

Why analysts watch it

Because it filters out the speculative noise of spot price, Realized Cap is read as a measure of capital actually committed and held. Periods where market cap falls below Realized Cap have historically coincided with the aggregate market holding coins at an unrealized loss. It is the denominator in several derived ratios and the foundation for age-weighted views of the supply.

This metric is educational and not trading advice. For related concepts see the Realized Price and MVRV Ratio entries, and review UTXO mechanics for how the underlying data is derived.
