The crypto market climbed 8.93% in the past week with net inflows totaling $152.46 billion, as the altcoin season index crossed the 53 mark—its highest level in three months, reached on June 3, 2026. The index measures capital flow into cryptocurrencies relative to Bitcoin, and the recent surge signals renewed investor interest after an eight-month stretch that saw the market shed more than $2 trillion since peaking in October 2025. Capital flows are gradually stabilizing, with momentum building as altcoin market capitalization now trends in step with the index. The market remains under pressure but shows signs of a potential rebound driven by selective altcoin performance.
Altcoin Season Index Crosses 53 on June 3, 2026
The altcoin season index crossed the 53 mark at the time of reporting, reaching its highest level in three months on June 3, 2026. The index measures the flow of capital into cryptocurrencies relative to Bitcoin. This does not yet mark altcoin season—the period when a broad set of altcoins post significant gains—a phase the market reaches only when the index climbs above the 75 mark.
One notable difference this time is that altcoin market capitalization is moving in step with the index. When the index last reclaimed the 53 mark in early June, altcoin capitalization was falling rapidly, but the two are now trending together.
