Top 3 Undervalued Altcoins to Watch in September 2026

In Brief

• Kaspa trades at $0.0282, still about 87% below its all-time high of $0.20741.
• Solana trades at $98.50, up 30.80% weekly but still 66% below its January 2025 peak.
• Hyperliquid trades at $82.34, just 1% below the fresh all-time high it set on August 23.

With Bitcoin up more than 20% since last week, traders are rotating into altcoins for larger gains. Three particular tokens, Kaspa, Solana, and Hyperliquid, are drawing renewed attention from market observers heading into the fall trading season.

However, all three altcoins are at different distances from their all-time highs. Analyst outlooks broadly support the undervalued narrative for two of the three under constructive market conditions, though outcomes will depend heavily on Bitcoin’s path and overall risk appetite going forward.
