CoinGecko's quarterly report shows crypto market capitalization rose 39.6% in the third quarter of 2026 to about $2.96 trillion. However, the report's top-10 spot exchanges handled $1.65 trillion in quarterly turnover, down 14.2% from the second quarter. Dollar open interest at CoinGecko's top-10 perpetual exchanges rose 40.6% during the quarter and ended September above $100 billion. The open-interest increase alone cannot establish fresh capital inflows or traders' leverage ratios because dollar valuations also depend on asset prices and contract specifications.
