Institutional Domination Could Narrow Altcoin Rallies

Crypto market maker Wintermute says its over-the-counter (OTC) flow report for the first half of 2026 reveals that institutional investors are increasingly dominating the market, potentially leading to fewer winners in future altcoin rallies.

Institutional counterparties generated a record-high 72% of spot flow across all tokens on Wintermute's OTC desk, up from 61% in the second half of 2025 and 59% in the first half of last year. This suggests that capital is becoming more concentrated in a smaller group of altcoins.

The firm found that liquidity was concentrating in assets favored by institutions while activity across the market's 'long tail' weakened. Between the first half of 2024 and the first half of 2026, the number of unique tokens traded by Wintermute's institutional counterparties grew by just 24%, compared with 76% among retail clients.

This trend is in line with previous findings that the market has been shifting towards a smaller group of 'blue-chip' altcoins. CryptoQuant CEO Ki Young Ju said on June 20 that the traditional rotation of Bitcoin profits into smaller crypto assets had 'basically disappeared', while data provider Kaiko found that the ten largest non-stablecoin altcoins accounted for about 80.5% of the market's capitalization.
