Most major cryptocurrencies have fallen in June, expanding the market’s overall weakness by the largest margin so far this year.

According to blockchain media outlet CoinPost on June 23 (local time), crypto market research service CryptoRank released market breadth data since the start of 2026. It said that among the top 100 coins excluding stablecoins, 74 of 85 tracked names fell in June.

That was 87.1 percent by weighting. By contrast, 11 coins rose in June, just 13 percent. CryptoRank calculated that the share of decliners in June was the highest level since the start of the year. It means far more names fell than rose across the market.

By monthly trend, the share of weak names was high from January and February. The share of decliners was 73 percent in January and 72 percent in February. It then fell to 62 percent in March and 36 percent in April, showing some improvement. In May, decliners were 46 percent and risers 54 percent, with gains in the majority. In June, the trend reversed sharply, sending the share of decliners up to 87.1 percent in a month.

Return metrics also showed the downtrend spread across the market. The average return in June was -8.6 percent and the median was -12.3 percent. CryptoRank pointed to some rising names lifting the overall average as the reason the average looked less negative than the median. As a result, the realised returns felt across many major coins may have been weaker than the average.

A median below the average suggests not only that few coins rose, but also that a small number of strong gainers distorted the overall indicators. Viewed across the broader market, it means widespread declines stood out in June rather than specific strong names. The calculations also covered leading coins excluding stablecoins, reflecting moves in the market’s core segment.

The trend also highlighted that May’s rebound did not carry into June. In May, risers outnumbered decliners, but in June the situation flipped completely. CryptoRank explained that the figures of an 87.1 percent share of decliners and 13 percent of risers show a move closer to a broad pullback in investor sentiment than a simple price correction.

A key point ahead is whether June’s sharp deterioration remains a temporary adjustment or hardens into the weakest month of the year. Based on data compiled so far, June is being recorded as the broadest downturn since the start of the year. If the advantage for risers seen in May does not return, the market’s internal resilience may remain weaker for some time, the outlet reported.
