Arbitrum (ARB) rose 33.57% in 24 hours to $0.113544 on September 1, 2026, recovering about 56% from its August 16 all-time low of $0.0727. The token had fallen roughly 79.4% from its September 13, 2025, all-time high of $0.5475 after spending about 207 days in a bottoming range. No verified Arbitrum ecosystem announcement, governance vote or exchange listing was identified as a catalyst. Instead, exchange-facing wallets recorded a net inflow of about 508,291 ARB, while on-chain screening flagged 99.1% of transfer volume as wash trading across 882 wallets. Retail wallets held about 0.4% of supply, and several large accumulator wallets were shown routing balances toward Binance and Bybit hot wallets. The data leaves the rally vulnerable to a rapid reversal if those transfers continue, although sustained exchange outflows and lower wash-trading levels would provide stronger evidence of genuine accumulation.
