The next significant rally for alternative cryptocurrencies may crown fewer victors, as institutional investors increasingly focus their trading activities on a more limited selection of digital assets, according to a new report from crypto market maker Wintermute.

Institutional Dominance on the Rise

In its over-the-counter (OTC) flow report analyzing the first half of 2026, Wintermute revealed that institutional counterparties were responsible for 72% of all spot token flow on its OTC desk. This figure represents the highest proportion ever recorded by the firm. It marks a significant increase from 61% in the latter half of 2025 and 59% during the first half of the same year.

These findings suggest a trend toward narrower and more selective altcoin rallies. Wintermute observed that institutional trading is becoming concentrated in a smaller number of tokens, with price surges fading more quickly. The firm stated that liquidity is consolidating in the assets preferred by institutions, which simultaneously weakens activity across the market's "long tail" of smaller tokens.

Further data illustrates this concentration. Between the first half of 2024 and the first half of 2026, the count of unique tokens traded by Wintermute's institutional clients expanded by only 24%. In sharp contrast, the number of unique tokens traded by retail clients grew by 76% over the same timeframe.

Wintermute also discovered a difference in trading behavior post-rally. When a token experienced a surge in price and volume, institutional activity tended to subside after approximately one day. Retail activity, however, typically stayed elevated for a period of about three days.

Broader Market Trends Corroborate Findings

Wintermute’s proprietary OTC data adds to growing evidence from the wider market that capital is clustering around a smaller group of altcoins.

On June 20, CryptoQuant CEO Ki Young Ju commented that the conventional rotation of profits from Bitcoin into smaller crypto assets had "basically disappeared.” Supporting this observation, data from CryptoQuant indicated that trading volume in altcoin pairs denominated in Bitcoin was hovering near its lowest point since 2021.

Market capitalization data also reflects this trend, with the 10 largest altcoins (excluding stablecoins) representing roughly 80.5% of the total market capitalization of all non-Bitcoin, non-stablecoin assets.

A similar concentration was identified in exchange trading by the data provider Kaiko. In a July 2025 report, Kaiko noted that the top 10 largest altcoins accounted for 63% of total altcoin trading volume, a notable increase from approximately 50% just several months earlier, while trading in smaller tokens declined.

Andrei Grachev, the managing partner of DWF Labs, also shared his view that broad-based altcoin rallies are being replaced by more selective, sector-specific movements. On March 15, Grachev said that an excessive number of tokens were competing for a finite amount of capital. He added that institutional investors largely remained concentrated on Bitcoin, Ether, and tokenized real-world assets.
