Rising dominance
Bitcoin is gaining market share. This can happen during BTC-led rallies or risk-off periods when altcoins fall faster.
Falling dominance
Capital may be rotating into altcoins, but market breadth should confirm whether the move extends beyond a handful of assets.
Read both signals
Combine dominance with the Altcoin Season Index to separate genuine broad rotation from isolated sector moves.
What dominance says today
On October 16, 2026 Bitcoin dominance is 59.26%: Bitcoin accounts for about $1.65T of a $2.78T crypto market, with BTC at $82,115. That is the high BTC concentration zone. Bitcoin holds a large share of total crypto market capitalization.
Dominance is down 0.5 pp from a week ago (59.7%), up 0.8 pp from a month ago (58.4%), up 2.7 pp from three months ago (56.5%), so the monthly trend is rising. Rising dominance means Bitcoin is gaining share — in a rally it leads, and in a sell-off altcoins fall faster.
Since July 14, 2026 dominance has ranged from 56.1% (August 14, 2026) to 59.7% (October 9, 2026).
This tracker treats 42% as the rotation threshold. Dominance is 17.3 percentage points above it, and the Altcoin Season Index reads 56/100. Neither signal points to altcoin season: Bitcoin still leads.
Dominance is Bitcoin’s market capitalisation divided by the total market capitalisation of all cryptocurrencies, from CoinGecko. Because stablecoins are part of that total, dominance can also fall when money moves into stablecoins rather than altcoins — which is why it is read together with breadth.
