Meme coin activity intensified over the past week across Robinhood Chain, BNB Chain and Solana, with numerous projects surpassing $10 million in market capitalization and attracting heavy community discussion. CASHCAT, the earliest prominent cat-themed Meme coin on Robinhood Chain, climbed above $320 million before falling to $190 million. MEME, linked to AMC and Robinhood's AMC stock token, rose from below $30 million to $170 million before retreating to $125 million after AMC CEO Adam Aron challenged Robinhood's unauthorized issuance of the token. Other Robinhood Chain projects included SHROOM, a Pons-issued token tied to stock-token liquidity pools, which rose from around $6,000 to $28 million; and MarsCoin, whose market cap jumped from $100 million to $265 million after Binance listed spot trading on Sept. 4, then declined to $150 million. On BNB Chain, Binance's Sept. 6 listing of Hakimi perpetual futures helped lift the token from $16 million to $90 million before it fell to $50 million. Cow Lai, Stonks and USELESS also reached peaks of more than $140 million, $19 million and $320 million, respectively. On Solana, STONK and ZCAT each rose above $180 million before settling near $130 million. STONK became the first stock-pairing Meme coin on Solana to exceed $100 million in market capitalization, while ZCAT imposes a 3% transfer tax used mainly to buy ZEC and distribute it automatically to eligible holders. Trader Bonk Guy said USELESS, MARSCOIN and PONS could be the fastest projects in their respective sectors to reach $1 billion in the new cycle, while trader BonkGuy said attention was shifting toward BNB Chain and MARSCOIN had become an early leader in the BNB Meme and stock narrative.
