Coinbase and Binance have seen a bump in market share following FTX's collapse.

Coinbase's share of the fiat exchange market has nearly doubled, up to 40% from 22.8% in September.

The Block tracks spot market share for cryptocurrency exchanges with fiat support. Only the largest exchanges with trustworthy reporting of exchange volume metrics are included.

Binance's market share for crypto-only exchanges rose to 87% in December from 82.7% in September before the demise of FTX, according to The Block's data.
