Top 5 Altcoins to Watch for September 2026

Five altcoins showed strong momentum in mid‑August and now face September events that could influence their next price moves. Below is a breakdown of each asset, recent price action, and upcoming catalysts.

Zcash (ZEC)

ZEC broke out three days before its spot ETF listing on August 25, reaching $888, just under the 1.272 Fibonacci extension at $903. The next extension target is $1,099. A community poll on the NU7 upgrade closes on September 14, asking whether to replace the halving schedule with a smooth issuance curve. A rejection at $903 could pull price back toward the $750 breakout level.

Monero (XMR)

Monero surged 26.5% in seven days after breaking above its May swing high on August 22, testing the 0.5 Fibonacci retracement at $538. The asset now eyes the 0.618 golden pocket around $600 and its record high of $799.89. THORChain enabled native XMR swaps on August 25, but no dated September catalyst is identified. Open interest has roughly doubled to $278 million, indicating a derivatives‑driven move.

Hyperliquid (HYPE)

HYPE cleared a prior record at $77 on August 22 and rose to $86.71 five days later. The token routes 99% of order‑book fees into buybacks, generating $58‑$80 million per month. A token unlock of about 14.2 million HYPE, valued near $1.2 billion, is scheduled for September 29, with roughly 47% allocated to insiders. Historical monthly releases have moved price between –7% and +1% in recent months, suggesting a potential range of $70‑$76 from the current $81.78.

Uniswap (UNI)

UNI activated v4 protocol fees and Robinhood Chain fees in late July, and August saw a record burn funding of $8.9 million—about double the pace since January. UNI set a higher low on August 14 and cleared swing highs at $3.99 and $4.43. The token now tests the 0.618 retracement near $4.94, with resistance at $5.66 and the January high at $6.57. The Senate cloture vote on the CLARITY Act in mid‑September could affect the breakout.

Solana (SOL)

SOL broke the 0.382 retracement at $93.98 and is confirming the 0.5 level at $104.44 as support. Validators approved SIMD‑0550 on August 28, doubling annual disinflation from 15% to 30%. Bitwise reported $1 billion in Solana ETF assets the same day. Transaction V1, which triples the maximum transaction size, activates on September 9. Despite chart strength, network fees fell 44% quarter‑over‑quarter, and Solana’s share of global fees dropped to 17.3% from 26.6%.

What to Watch Next

The September calendar includes Transaction V1 (Sept 9), the Zcash NU7 poll closure (Sept 14), the CLARITY Act Senate vote (mid‑month), and the Hyperliquid unlock (Sept 29). Four of the five assets have a dated event; Monero’s path remains driven by market flow.
