Ethereum News Today: Ethereum ETFs Draw $1 Billion Inflow Driving Altcoin Gains Including 18.64% ARB Surge

Ethereum continues to drive performance across the altcoin market as its ecosystem tokens record significant gains. On August 12, 2025, U.S.-listed spot Ethereum ETFs saw a record $1 billion in net inflows, the highest daily figure since their launch, reflecting robust institutional and retail investor interest in the network [1]. This surge in ETH-related activity has spilled over into the altcoin space, with several Ethereum-based tokens posting sharp increases.

Among the top performers, Arbitrum’s native token ARB rose over 18.64% in 24 hours, reaching a price of $0.5697 [2]. The rally in ARB aligns with growing adoption of Ethereum’s Layer 2 solutions and continued innovation in decentralized application development. Other Ethereum-based tokens also posted notable gains, including GTC (37.9%), EIGEN (17.47%), ZK (15.24%), ETHFI (12.52%), and OP (9.77%) [2].

Ethereum itself has gained momentum, with its price now just 2.7% away from its all-time high, as the total crypto market cap and Bitcoin prices also reached record levels [2]. The broader altcoin rally is being fueled by Ethereum’s strong fundamentals and expanding ecosystem, which continues to attract developers and investors alike.

Analysts have highlighted potential future price targets for ARB, with some forecasts suggesting a price of $0.5098 by 2026 based on a projected 5% annual growth rate [3]. Meanwhile, Altlayer’s native token, ALT, also saw a 12% increase in a single day, showcasing the competitive and dynamic nature of Ethereum’s Layer 2 landscape [4].

AI-driven predictions have further fueled market optimism, with models like ChatGPT-5 estimating that Ethereum could reach $5,400 by September 2025, driven by favorable technical indicators, regulatory clarity, and growing institutional demand [5]. While such forecasts are speculative, they reflect a broader market belief in Ethereum’s ability to lead the next phase of crypto growth.

Ethereum’s role as the central driver of the altcoin rally underscores its importance in the broader crypto market. As the ecosystem continues to expand and attract new participants, the performance of Ethereum-based tokens is expected to remain closely tied to the network’s fundamental developments and network activity in the coming months.
