Ethereum vs Solana: Which Will Hit a New ATH First?

Ethereum and Solana are trading at roughly $2,115 and $86, respectively, well below their all-time highs; ETH peaked at $4,953 in August 2025, while SOL topped at $294 in January 2025. Ethereum’s Glamsterdam upgrade, expected to launch in June or by Q3 2026, will raise throughput to 10,000 transactions per second and increase the block gas limit from 60 million to 200 million, potentially pushing ETH past $2,500 and toward $5,000 if momentum resumes. Solana counters with the Alpenglow upgrade, aimed at replacing its consensus layer and shrinking finality from 12.8 seconds to 100–150 milliseconds, with testing ongoing and potential live deployment in Q3 2026; a successful launch could lift SOL above $100 and perhaps near $300 by year-end.
