Solana rises to ~$96 on Alpenglow upgrade

Solana’s weekend move was framed in market chatter as a reaction to Alpenglow, but the clearest primary-source update is that the upgrade is still pending rather than live. The Solana Foundation said on February 3 that Alpenglow was “under development” and expected by Agave 4.1, describing it as a new consensus protocol aimed at 150 millisecond confirmation times. That matters because the headline claim — SOL rising to about $96 on “Alpenglow upgrade” news — mixes two separate things: price action and protocol roadmap. CoinGecko’s historical data show SOL closed at $85.16 on May 17 and $85.25 on May 18, while CoinMarketCap’s historical page shows SOL at $85.30 on May 18 and $84.21 on May 19, suggesting the roughly $96 level was reached intraday earlier in May rather than on those closing dates. (solana.com) ### So what is Alpenglow, exactly? The Solana Foundation’s upgrade roadmap says Alpenglow would replace parts of Solana’s current consensus design, including Proof of History and on-chain vote transactions, with a simpler mechanism intended to improve reliability and reduce confirmation times. The same page says the feature is expected in Agave 4.1 and remains under development. (coingecko.com) Anza, a Solana-focused infrastructure developer, described Alpenglow in a May 19, 2025 blog post as a “new consensus protocol” for Solana and published a technical explanation alongside a white paper. A related Solana forum proposal says the redesign centers on a voting protocol called Votor and a data propagation layer called Rotor. ### Did Solana actually trade near $96? (solana.com) CoinGecko’s May price history shows SOL closed at $96.49 on May 10 and $97.32 on May 11 before falling back into the mid-$80s by May 17-19. CoinMarketCap’s historical data show a similar pattern, with SOL closing at $96.43 on May 10 and $97.35 on May 11. Those figures do not rule out a weekend rebound narrative, but they do undercut any simple reading that SOL newly “rose to $96” on May 18 or May 19. (anza.xyz) Based on the available historical snapshots, the token had already traded at that level earlier in the month. ### What do the ETF numbers show? SoSoValue’s U.S. spot Solana ETF dashboard shows cumulative net inflows of about $39 million across listed products. (coingecko.com) The same dashboard shows Bitwise’s BSOL with $5.36 million of one-day net inflow, Fidelity’s FSOL with $1.31 million, and the rest of the listed funds flat on that daily measure in the snapshot available today. Those figures support the narrower point that money was moving into U.S. spot Solana ETFs, but they do not by themselves establish that the flows were caused by Alpenglow news. (coingecko.com) The dashboard is a fund-flow tracker, not a statement of investor motive. ### What is the more precise way to describe this story? The cleaner version is that traders and social posts linked Solana’s relative strength to renewed attention on Alpenglow and related network changes, while primary sources show Alpenglow itself has not yet shipped. (sosovalue.com) The Solana Foundation’s roadmap also lists SIMD-123, a block revenue distribution feature, as under development for the same Agave 4.1 release track. The next concrete milestone is on Solana’s own roadmap: Agave 4.1. The Solana Foundation says Alpenglow and SIMD-123 are both expected in that release, though the page also says version numbers and timelines are subject to change. (solana.com)
