Meme Coin Market Heats Up: Dogecoin and MarsCoin Lead the Pack

The meme coin market is heating up in October 2026, with five popular picks under the spotlight. Dogecoin (DOGE) leads the pack with a massive $14.49B market cap, roughly 20 times that of the other four combined. However, it's not just about size - the heat check reveals that MarsCoin (MARS) trades about 71% of its market cap in a day, making it one of the most active coins.

Cash Cat (CASHCAT), launched on Robinhood Chain in July 2026, has been gaining traction after being listed by the platform. Its price jumped by over 1,000% in a single day after Robinhood's CEO mentioned that the chain is suitable for memes. BUILDon (B) and Fartcoin (FARTCOIN) also made the list, with the latter being an AI-generated coin with no utility or roadmap.

The meme coins are not without risks, however. Violent swings in price can be a major concern, as seen with Fartcoin's 12.30% drop in a day. Thin volume and big holders also pose potential threats to investors.
