Altcoin Volume Surges as Season Index Rises: Will Altseason Arrive in 2026?

May 13, 2026 | VECS News

After months of Bitcoin‑dominated trading, the crypto market is showing the clearest signs of capital rotation into altcoins since the 2021 bull run. Bitcoin dominance, which climbed toward 60% in early 2026 driven by spot ETF inflows and institutional accumulation, is now displaying its first technical cracks . A bearish MACD crossover on the BTC dominance chart suggests the uptrend in Bitcoin's market share is losing momentum, a signal that historically has preceded major capital moves into smaller assets.

The most compelling data point comes from trading volume. CryptoQuant analyst CryptoOnchain has identified that the Altcoin Volume Increasing Trend has activated: the 30-day moving average for altcoin trading volume on centralized exchanges has crossed above the 365-day average . This pattern proved highly accurate before the explosive altcoin rallies of 2017 and 2021. On Binance, altcoins' share of combined BTC and ETH trading volume has climbed from 31% to 49%, approaching parity with the two largest assets combined .

However, the headline indicator tells a more cautious story. The Altcoin Season Index from CoinMarketCap currently reads 50, exactly midway between Bitcoin Season (below 25) and confirmed Altcoin Season (above 75) . The index briefly touched near 100 in mid-March before pulling back sharply and spent most of April oscillating near the lower end of the range. Its recovery to 50 is significant, but the 25‑point gap to confirmation means the market is not yet in altseason territory.

The contradiction between the early rotation signals and the still‑modest index reading defines the current market. Three independent datasets confirm capital is moving: the AltSeason Index has risen to 28.6 from Bitcoin Season levels above 20, the CEX volume ratio is climbing, and altcoin share of trading volume continues rising . Yet the index remains 47 points below the 75 threshold. Analysts emphasize that rotation has started but has not arrived. The current magnitude of altcoin volume relative to Bitcoin is only about 15‑20% of what characterized the 2021 altseason .

Price action is beginning to reflect this selective rotation. Solana (SOL) and Sui (SUI) have posted double‑digit gains in recent sessions while Ethereum remains relatively stable . More dramatically, Toncoin (TON) nearly doubled in three days following specific ecosystem catalysts . This pattern of Layer‑1 blockchains breaking out first mirrors the structure of previous cycles: in both 2017 and 2021, capital first rotated from Bitcoin into ETH, then into smaller assets with independent catalysts, before spreading into broader market rallies.

Global experts offer diverging views on whether 2026 will deliver a traditional altseason. Michaël van de Poppe, CIO and founder of MN Capital, believes altcoin season is "definitely possible" and argues that many altcoins that have been in a prolonged bear market for about 18 months will witness a profitable rally in the short term . He cautions, however, that a "full-blown altcoin run" remains unlikely, suggesting the rotation will target specific sectors rather than lifting all assets indiscriminately.

A contrasting perspective comes from CoinEx Research chief analyst Jeff Ko, who predicted as early as December 2025 that no traditional altseason would materialize in 2026 . Ko argues that liquidity will concentrate exclusively in blue‑chip survivors with genuine adoption, leaving most altcoins behind. He points to the structural shift created by spot Bitcoin ETFs, which now hold over $87 billion in dedicated Bitcoin-only products. This institutional capital has no direct pathway into altcoins, a constraint that did not exist in previous cycles .

On‑chain data supports the cautionary view. CryptoQuant data shows that approximately 38% of all altcoins (excluding Bitcoin, Ethereum, and stablecoins) are trading near their all-time lows, a figure exceeding the levels seen immediately after the FTX collapse . The Altcoin Season Index has also remained stubbornly low throughout most of this cycle. Its peak in early 2024 stayed well below the 75 threshold, leading some analysts to conclude that the current cycle has not experienced a genuine altseason at all, only brief and shallow rotations .

Veteran futures trader Peter Brandt offers an even more skeptical macro perspective. Brandt projects the next bull market peak to occur around September 2029, aligning with the four‑year cycle theory, and warns of an extended bear market ahead . In his view, Bitcoin's historical pattern of 80%+ declines following parabolic advances remains intact, suggesting that any altcoin rally in the near term would operate within a broader corrective structure rather than the start of a new speculative mania.

What would confirm altseason? Analysts point to two key thresholds. First, the Altcoin Season Index must cross and hold above 75 for at least three consecutive weeks . Second, Bitcoin dominance needs to break below 59.63% on a weekly closing basis and sustain that level . As of May 2026, neither condition has been met. The volume trend is real, the MACD crossover is valid, and selective assets are already moving. But the structural shift required for a full altseason remains unconfirmed. The market stands at a crossroads, and the next 30 days will determine whether 2026 joins 2017 and 2021 in crypto history or repeats the failed rotations of 2022‑2025.
