Solana Blockchain Upgrades and ETF Inflows Surge May 2026 - Alpenglow Testing & $39M ETF Inflows

Key points

• •The Solana ecosystem is undergoing significant infrastructural upgrades with the Alpenglow project entering testing and live validator phases by mid-May 2026. This upgrade promises to deliver transaction finality speeds up to 100 times faster, with finality reduced to approximately 150 milliseconds, significantly enhancing Solana’s performance and positioning it as a competitive platform for decentralized applications and finance.[Cointribune][CoinCentral]
• •Institutional investor confidence in Solana is rising sharply, as demonstrated by ETF inflows totaling $39 million in one week during early May 2026 and a cumulative $1.07 billion in assets managed across eight U.S.-based Solana ETFs. This momentum has contributed to a surge in futures open interest by 30% and price targets reaching up to $120, marking a potential bull run reversal after a prolonged downtrend.[TradingView][Reddit - r/solana][深潮TechFlow]
