Solana’s Rally Explained: How $15B in Stablecoins and ETF Flows Pushed $SOL Higher

Solana is experiencing a strong resurgence. Just recently, $SOL hit $236 before reconsolidating, its highest since September. This is due to a trifecta of factors. A new all-time high in stablecoin supply on the network, growing inflows into its SOL + Staking ETF (SSK) and anticipation for the upcoming Alpenglow upgrade.

Solana stablecoin growth led by USDC and USDT, now totals about $15 billion on Solana. Meanwhile, institutional capital is showing confidence via the REX-Osprey SOL + Staking ETF (SSK), which has hundreds of millions in assets.

The Rise in Stablecoin Supply on Solana

The major push behind $SOL’s recent move is the massive increase in stablecoin issuance on the Solana network. According to DeFi Llama, Solana’s stablecoins now total roughly $15.08 billion, surging big from earlier in the year.

USDC leads the pack with over $10.76 billion on the network, followed by USDT with $2.45 billion. Solana added more than $1.445 billion in stablecoin supply in a single week recently, boosting network liquidity.

Stablecoins are liquidity bridges in DeFi. Their presence increases trading activity, lending, borrowing and capital flows within the ecosystem. The more stablecoin liquidity on a chain, the more flexible users and protocols become in choosing that chain for operations.

With Solana’s stablecoin base at an all-time high, the network’s internal economy becomes more self-sustaining. That’s not just for speculative trading but deeper ecosystem use. The shows an increasing confidence in Solana stablecoin growth.

Institutional Confidence via SOL + Staking ETF Inflows

Institutions are also joining the party to boost Solana’s momentum. The REX-Osprey SOL + Staking ETF (SSK), launched in July 2025, is the first U.S. ETF to combine spot SOL exposure with on-chain staking rewards.  It’s designed to distribute staking rewards generated on Solana’s network to shareholders, bridging crypto participation with traditional finance infrastructure.

SSK took off fast, within 12 trading days of launch, it hit $100 million in AUM.  In recent updates, it’s now at $338 million AUM while the SEC is still deliberating on multiple spot SOL ETFs.

The ETF’s design is attractive: it provides regulated access to $SOL while capturing staking yield. For institutional investors who are hesitant to hold direct token custody or protocol governance, SSK lowers the bar.

Technical Momentum and Price Structure

$SOL’s price jumped to $236, which is a clear breakout from the consolidation zone. The bounce started after it touched a low of $190 last month which is the lower bound of the ascending channel.

$SOL has also broken above its 50-day and 100-day exponential moving averages; a notable technical confirmation of upward momentum. The next resistance zone to watch is near $253, which is the upper side of the ascending channel. Above that could open the path to $295 all time high.

However, resistance liquidity and profit-taking zones may be obstacles; the price needs to follow through with volume to sustain the move.

Alpenglow Upgrade and Protocol Level Catalysts

Beyond capital trends and charts, Solana has internal levers that can catalyze further growth. The upcoming Alpenglow upgrade is one of them. While details are limited, the community expects improvements in throughput, latency, transaction parallelism and scalability features. Analysts believe the upgrade can increase network capacity and developer confidence.

Coupled with stablecoin growth, deeper liquidity, and infrastructure improvements, Alpenglow can be a technical catalyst. If implemented smoothly and adopted widely, it can strengthen the case for SOL to break into new highs.
