Solana continues to evolve, and Grok, Elon Musk's AI, is keeping an eye on this and offering us a clear prediction of what we can expect from this cryptocurrency in September 2025, especially with the advent of ETFs and the arrival of Alpenglow.
The cryptocurrency market continues to be a space of high volatility and opportunity, where Solana (SOL) has established itself as one of the most prominent blockchains thanks to its scalability, speed, and low transaction costs. As of August 28, 2025, Solana's price stands at approximately €184,87, showing technical strength above its key moving averages.
This position, combined with technological developments and growing institutional interest, has generated renewed optimism about the future of this cryptocurrency.

Solana's current value and Grok's prediction for September 2025
As of August 29, 2025, Solana is trading at €184,87, reflecting a 23,03% growth over the past seven days and a 41,2% increase over the past 30 days. This bullish performance occurs amid a recovering crypto market, driven by renewed institutional interest and positive expectations surrounding technological developments. The Solana blockchain, known for its ability to process up to 65.000 transactions per second (TPS) thanks to its Proof-of-History (PoH) consensus mechanism combined with Proof-of-Stake (PoS), continues to attract developers and users in sectors such as DeFi, NFTs, and gaming.
Grok, the artificial intelligence developed by xAI, has analyzed multiple technical, fundamental, and sentiment indicators to provide a Solana price prediction for September 2025. Based on recent data and market projections, Grok estimates that Solana’s price could average €296,44 in September, with a fluctuation range between €162,29 and €389,84, according to DigitalCoinPrice projections.
This prediction reflects significant upside potential, with an average increase of 56% from the current price. Grok's estimate aligns with technical analysis indicating that Solana remains above its 20-day moving average (€178,32), a bullish signal, although the MACD shows some selling pressure that could moderate in the coming weeks. Factors such as institutional adoption, technical improvements on the network, and positive community sentiment support this optimistic outlook.
Alpenglow: A technological boost for Solana
One of the most anticipated developments in the Solana ecosystem is the update alpenglow, proposed by Anza, an infrastructure company spun off from Solana Labs. This upgrade, described as “the single largest change to the Solana core protocol,” aims to reduce transaction completion times from roughly 12,8 seconds to just 150 milliseconds. Alpenglow will replace the current TowerBFT consensus system with a new protocol called Votor, which optimizes block voting and finalization using a two-track system: one that finalizes blocks in one round with 80% of the network’s stake, and another that requires two rounds with at least 60% participation.
This improvement in completion speed could position Solana as a leading blockchain for real-time applications such as gaming, payments, and high-frequency trading, which have traditionally relied on centralized systems due to the slowness of other blockchains. According to Raye Hadi of Ark Invest, “This upgrade perfectly aligns validator incentives, making their work proportional to their network stake.” The Solana validator community is already voting on this proposal through the SIMD-0326 governance process, and a public testnet could be implemented in the coming months, with full mainnet deployment subject to community approval.
The potential impact of Alpenglow on Solana's price is significant. By improving network speed and reliability, Solana could attract more developers and projects, increasing demand for SOL transactions and, consequently, its value. Furthermore, the ability to compete with centralized internet services could broaden Solana's appeal to businesses and institutions, strengthening its market position. However, risks associated with validator coordination and network stability, especially with the primary validator client Agave, should be carefully monitored.

Solana ETFs and Community Support: Keys to Price Momentum
Another crucial factor that could boost Solana’s price is the growing interest in SOL-based exchange-traded funds (ETFs). On August 18, 2025, VanEck’s Solana ETF (VSOL) appeared on DTCC listings, a move that mirrors pre-approval patterns seen with Bitcoin and Ethereum ETFs. According to an August 19 note from Bernstein, Solana is positioned to lead the next wave of ETFs alongside Ethereum, which could unlock significant institutional demand. X user @johnmorganFL, with 2,1 million followers, predicted that Solana ETF approval could replicate Bitcoin's 2024 boom, projecting a price range of €440 to €600 by 2026.
The Solana community also plays a pivotal role in its growth. Despite past challenges, such as the fall of FTX and Alameda Research in 2022, which led to panic selling and a price crash from €28 to €9 in just a few weeks, the community has demonstrated resilience. The decision to postpone the release of locked SOL during the FTX crisis helped stabilize the price, and the current enthusiasm for developments like Alpenglow and the launch of tokens like YZY (despite its 66% drop after a brief peak of €3.000 billion in market capitalization) reflect an active and engaged community. This activity drives blockchain adoption for DeFi projects, NFTs, and memecoins, increasing demand for SOL.
ETFs, by providing a regulated vehicle for institutional investors to enter the Solana market, could amplify this demand. Recent institutional accumulation, such as the purchase of 153.225 SOL (€23,7 million) at an average price of €154,85 in July 2025, suggests growing confidence in Solana's long-term potential. The combination of a vibrant development ecosystem and the inflow of institutional capital could be a key catalyst for a sustained price increase.
What to expect from Solana in September and key signals to monitor?
By September 2025, Solana faces a promising outlook, but with risks that investors should consider. Grok's prediction of an average price of €296,44 is based on a bullish scenario driven by the crypto market recovery, Alpenglow's progress, and ETF expectations. LongForecast It projects a September closing price of €244, with a range of €175 to €261, indicating moderate growth but with possible fluctuations.
Key signals to monitor include:
- Alpenglow Progress: The results of the community vote on SIMD-0326 and the launch of a public testnet will be critical indicators of the success of this update.
- Regulatory developments: Progress in ETF approvals by the SEC, especially following amended filings, could trigger significant price movements.
- Technical indicators: Investors should monitor the 50-day moving average (projected at €198,79 by the end of September) and the RSI, currently at 56,89, which indicates a neutral market but with upside potential if it rises above 70.
- Market sentiment: The Fear and Greed Index, currently at 46/100, reflects mixed sentiment. A rise toward greed levels (70 or higher) could amplify the bullish momentum.
- Institutional activity: New SOL accumulations by institutions, similar to those in July 2025, would be a positive sign.
In conclusion, Solana is in a strong position to experience significant growth in September 2025, driven by technological advancements like Alpenglow, the potential of ETFs, and the support of an active community. However, investors should remain vigilant about technical and regulatory risks, as well as the inherent volatility of the crypto market. Conducting thorough research and managing risk appropriately will be crucial to capitalizing on the opportunities Solana offers during this exciting period.
