One of America's largest traditional brokerages is broadening its crypto footprint in a meaningful way. According to CoinMarketCap, The Block, and Cryptopolitan, Charles Schwab announced on August 27 that it plans to add Solana (SOL), Avalanche (AVAX), and Chainlink (LINK) to its Schwab Crypto platform in the coming months. The move follows Schwab Crypto's launch in May 2026, which initially gave clients access only to Bitcoin and Ethereum. The firm oversees $13.04 trillion in client assets across 39.9 million active brokerage accounts as of July 31, according to CoinMarketCap. The Block noted that the expansion is part of Schwab's stated aim to 'thoughtfully expand' its digital asset offering with established cryptocurrencies that align with client demand. The platform charges 75 basis points per trade and is available in all US states except New York and Louisiana. CryptoRank reported that within 24 hours of the announcement, Solana rose approximately 4%, Avalanche gained 3.5%, and Chainlink increased 2.8%. Yahoo Finance noted that Schwab also plans to add further cryptocurrencies and digital assets over time. The move signals accelerating mainstream brokerage adoption of altcoins and could redirect retail flows away from crypto-native exchanges toward regulated financial infrastructure.
