Solana (SOL) investors are witnessing rising volatility as a surge in whale activity signals deadly selling pressure in the market. Despite a strong rally above $250 earlier in September, market sentiment appears to be shifting, with whale deposits into centralized exchanges hinting at potential headwinds ahead. Most recently, a staggering 312,233 SOL tokens were deposited into Coinbase, fueling concerns that whales may be positioning for significant profit-taking.
Solana Whale Deposits Signal Rising Selling Pressure
Blockchain tracker Whale Alert reported one of the largest Solana transfers in recent weeks, with 312,233 SOL valued at approximately $75.1 million, moved from an unknown wallet to Coinbase Institutional on September 21. The size and timing of this large-scale transfer immediately raised concerns that whales could be positioned to sell.

Before this transfer, Whale Alert had flagged another massive transaction of 227,928 SOL, worth around $54.5 million, being funneled into Coinbase on the same day. Together, these two deposits represent more than $129 million in Solana potentially at stake of being sold off.
The implications of such moves are significant, as large holders typically send tokens to exchanges with the intention to sell, ultimately adding considerable downward pressure to the market. Notably, Solana’s price rally in September has been fueled by strong demand; however, these recent transfers raise the risk of oversupply, particularly as the token hovers around $224. If whales follow through with the selling, it could cap SOL’s bullish breakout attempt and force the price back to lower support zones.
Interestingly, this is not the first time Solana has faced similar whale-driven headwinds this month. Just over a week ago, blockchain analytics platform Lookonchain reported multiple whale dumpings into various crypto exchanges. A wallet tagged “CMJiHu” deposited 96,996 SOL ($17.45 million) into Coinbase, while “5PjMxa” moved 91,890 SOL ($15.98 million) to Kraken. The same day, another wallet “HiN7sS” transferred 37,658 SOL ($6.73 million) to Binance, securing a profit of $1.63 million. These earlier transfers, combined with the latest inflows, show a pattern of whales steadily reducing their exposure as market sentiment shifts.
SOL Momentum Weakens Under Heavy Selling
Crypto analysts now view Solana as being at a pivotal crossroad, where strong fundamentals clash with mounting selling pressure and technical risks. Market expert Tom Tucker notes that SOL has climbed more than 150% in 2025, but its rally is showing signs of fatigue. The analyst’s chart reveals a rising wedge formation, often a precursor to a breakdown, combined with weakening momentum indicators.

The Relative Strength Index (RSI) is narrowing into a triangle, suggesting indecision, while the MACD has flattened after months of strength. This setup, when paired with heavy whale deposits into exchanges and rising sell pressure, underscores the growing possibility of a short-term pullback.
Yet, the outlook is not entirely bearish. Tucker points to optimism surrounding a potential Solana ETF, the upcoming Alpenglow upgrade, and steady treasury accumulation as fundamental drivers that could extend SOL’s long-term growth.
