Market Dominance

Methodology

Market dominance is the share of the total crypto market capitalization held by an asset or a group of assets. Watching how these shares change shows how market value is distributed between Bitcoin, Ethereum, stablecoins and the rest of the market. A change in dominance describes a change in relative market value; it is not a direct measure of money moving from one asset to another.

The four groups

BTC.D

Bitcoin's market capitalization as a share of the total.

ETH.D

Ethereum's market capitalization as a share of the total.

Stablecoin.D

The combined market capitalization of stablecoins as a share of the total. Stablecoin market cap: Data: CoinGecko.

Others.D

The market capitalization of every other crypto asset tracked by FMChart, excluding Bitcoin, Ethereum and stablecoins.

Two ways to measure the total

Including stablecoins (default): the total is the FMChart crypto universe plus the stablecoin market cap, so BTC.D, ETH.D, Stablecoin.D and Others.D add up to 100%. This view is available from 31 Oct 2026.

Excluding stablecoins: the total is the FMChart crypto universe without stablecoins, so BTC.D, ETH.D and Others.D add up to 100%. This view has a longer history. The two views are never mixed on one chart; the label above the chart always names the total in use.

Reading the Chart

Percentage points

Changes are shown in percentage points (pp): a move from 59.50% to 60.00% is +0.50 pp. The 24h change on each card compares the latest hourly value with the value 24 hours earlier.

Estimated period

In the Excluding stablecoins view, values before 31 Oct 2026 are reconstructed from historical market data and shown as a lighter shaded area. They follow the same definition but may differ slightly from values recorded live.

Timeframes

1D, 7D and 1M use hourly candles; 3M and 6M use 4-hour candles; 1Y and ALL use daily candles. All times are UTC.

How Events Are Detected

Event markers highlight unusually large dominance moves. For each candle, the change over a short window (4 hourly candles, or 3 candles on the 4-hour and daily views) is compared with the usual size of that group's moves over the previous period, using a robust measure that is not distorted by a few extreme moves and that only looks at earlier data.

A move is marked when it is at least 3.5 times the usual move: Minor from 3.5×, Major from 5× and Extreme from 7×. Each moment keeps only its strongest event; related event types are listed in its details.

To avoid false signals, candles with incomplete market coverage are skipped, as are moves mostly explained by assets entering or leaving the universe, by a sudden change in one asset's supply, or by a change in the stablecoin category. Events need at least 7 days of earlier data.

BTC Leadership

Bitcoin's share rose unusually fast while the share of other crypto assets fell.

ETH Rotation

Ethereum's share rose unusually fast and faster than Bitcoin's.

Risk-Off

The stablecoin share rose unusually fast while the total market cap fell. Shown only when stablecoins are included.

Altcoin Rotation

The share of other crypto assets rose unusually fast while Bitcoin's share fell.

Altcoin Share Contraction

The share of other crypto assets fell unusually fast.

Market Divergence

The total market cap and Bitcoin's share both moved unusually far, in opposite directions.

Reversal

A group's share turned direction after a sustained move, with an unusually large change.
