Top 3 Undervalued Altcoins to Watch in September 2026

Bitcoin’s recent rally of over 20% has prompted traders to shift focus toward altcoins in search of higher returns. Among the many projects, three tokens—Kaspa (KAS), Solana (SOL) and Hyperliquid (HYPE)—are highlighted for their perceived undervaluation as the market heads into the fall season.

Kaspa (KAS)

Kaspa is trading around $0.0282, up 1.34% in the last 24 hours. The price remains roughly 87% below its all‑time high of $0.20741 recorded on August 1, 2024. Analysts note the near‑complete issuance of its supply and recent network upgrades as positive factors. Scenario‑based projections suggest a potential rise to $0.035‑$0.045 if network activity expands, while a bearish view places it near $0.022‑$0.025 if market conditions weaken.

Solana (SOL)

Solana is priced at about $98.50, approximately 66% below its peak of $293.31 reached on January 19, 2025. Improvements to tokenomics, such as possible inflation cuts and stronger fee‑burn mechanisms, are cited as supportive. July on‑chain transaction volume hit a record $4.2 billion, up 13.5%. Bullish scenarios project a move toward $130‑$180 or higher with increased institutional inflows, whereas a risk‑off environment could test the $75 support level.

Hyperliquid (HYPE)

Hyperliquid trades near $82.34, up roughly 40% over the past week, and sits just 1% below its all‑time high of $83.27 set on August 23. Market participants view the token as attractively priced given its strong perpetual trading revenue and expanding infrastructure. Positive outlooks foresee price targets of $100‑$150 with sustained volume growth, while a bearish scenario could see a pullback to $60‑$70 amid profit‑taking or broader market corrections.
