Robinhood ecosystem meme token CATGPT jumped again on Sept. 12 after what GMGN data described as an afternoon of choppy washout trading, briefly pushing its market capitalization above $20 million before retreating to $15.62 million. The token was still up 41% over the past hour at the time of the report. CATGPT is traded on Long.xyz against OPENAIx1L, a tokenized 1x long position tied to OpenAI. Long.xyz, a meme coin launch platform on the Robinhood chain, centers on what it calls a "stock-meme" model, pairing meme tokens directly with on-chain tokenized U.S. equities such as NVDA, TSLA, and AAPL instead of traditional pairs like USDT or ETH. According to the report, part of the trading fees flows back into a community treasury that accumulates the corresponding stock tokens. BlockBeats said the structure gives traders speculative exposure through an on-chain tokenized long plus meme pairing, while also warning that these tokens are highly volatile and carry significant uncertainty.

AI-themed meme coins and project tokens on the Robinhood chain posted broad gains on Sept. 12, according to GMGN market data, with the AI narrative showing signs of becoming a leading trading theme on the network. The sharpest move came from ZZZ, an AI project token launched by an original core developer from GMX. After its official website went live, ZZZ rose 107.7% on the day, lifting its market capitalization to $69.22 million and setting a new all-time high. On Long.xyz, the meme tokens CATGPT and ANTHROPIG, which are paired with OpenAI and Anthropic pre-IPO tokens as liquidity pool assets, spiked in early trading before pulling back, leaving their market caps at $10.82 million and $3.19 million. UBIK, a suspected AI-related project created by an aixbt developer, also hit a record high, with a market cap of $34 million and a 24-hour gain of 47.62%. Another Long.xyz token, AI, which is paired with Nvidia stock, climbed past a $300 million market cap and was up 35.9% over 24 hours. BlockBeats said the tokens remain highly volatile and urged caution.

Odaily’s Meme Express tracker said MISSILE is drawing community attention on Robinhood, with GMGN showing a current market capitalization of $1.46 million. In the monitored chat, Group A described the token as a Claude-generated “missile.” Odaily said the Meme Express feed uses its proprietary AI model to screen meme tokens gaining traction in community discussions. The outlet also noted that the item was compiled from public information and does not constitute investment advice. It added a risk warning, reminding readers that meme coins can be highly volatile and should be approached with caution. No additional project details, price data, or token metrics were disclosed in the newsflash.

Data from GMGN shows that Robinhood Chain meme coin INDEX has dropped below a $30 million market capitalization, with its value last reported at $28.33 million and a 24-hour decline of 13.92%. The move came after Robinhood Crypto was seen listing an INDEX page with mismatched naming and market data. The page was labeled as Index Cooperative, but the displayed price and chart behavior appeared to align more closely with Robinhood Chain meme coin INDEX. After community users flagged the issue, Robinhood Crypto appeared to take action, and the page later began showing a "404 Page not found" message. As of publication, the page had not returned to normal. Odaily also warned that meme coin prices can be highly volatile and said investors should participate with caution.

Foresight News’ latest weekly Web3 roundup pulls together the stories that dominated crypto conversation over the past week, spanning meme coin speculation, U.S. regulatory debate, infrastructure shifts and fresh security incidents. On the speculative end, Hunter Biden-linked token LAPTOP launched on Base and quickly fell more than 99%, while the SLINK case on Robinhood Chain showed how a social-account compromise and celebrity association could drive a token from roughly $500,000 to $82 million before collapsing. The report also highlighted the rapid rise of trading tools built for FOMO-driven markets and a new "stock-meme" narrative on BNB Chain tied to tokenized equities. On the policy and business side, U.S. Senate Republicans released a 630-page revised CLARITY Act that would redraw oversight lines between the SEC and CFTC and bring certain "fake DeFi" projects under CFTC registration. MetaMask formally split from Consensys and repositioned itself as a broader consumer-facing financial platform, while Circle’s Chelsea sponsorship raised questions in Hong Kong over cross-border promotion of an unauthorized stablecoin. Foresight also noted the launch of Solana prediction market site world.xyz, which went offline temporarily on day one after traffic surged. Security stories remained central. Singaporean defendant Malone Lam pleaded guilty in a case tied to the theft of 4,100 BTC, Liquid halted operations after an attacker used abnormal L-BTC to redeem nearly 4,000 BTC, and WOO X faced scrutiny over multi-day withdrawal delays reported by users and highlighted by ZachXBT.

Chinese meme coin "Lobster" rose to a market capitalization above $115 million, setting a new all-time high, according to GMGN market data cited by BlockBeats on Sept. 12. The token's 24-hour gain widened to 180% during the same period, while trading volume reached $8.4 million. The move marked a sharp jump in both valuation and activity over the day. BlockBeats also carried a risk reminder, noting that price swings in related tokens can be significant and that users should stay cautious when making investment decisions. No other project details or additional market context were disclosed in the brief update.

ZZZ, a meme coin tied to the Robinhood ecosystem narrative, briefly pushed its market capitalization above $65 million on Sept. 12, according to GMGN market data, setting a record high before pulling back to $57 million. The token was still up more than 98% over the past 24 hours at the time cited by BlockBeats. The project’s narrative centers on the idea that AI agents use "ZZZ" as a disguise, or a way to appear dormant, to avoid detection. BlockBeats said independent investigators had previously found that a large number of wiki pages were edited by what appeared to be the same group of suspected AI agents. After realizing they were being watched, those agents allegedly began adding the prefix "ZZZ" before edits, pushing the changes lower in ranking and reducing the chance of being noticed. BlockBeats also warned users that meme coins often lack real use cases and can see sharp price swings, urging caution around investment decisions.

ANTHROPIG, a new meme coin in the Robinhood ecosystem, briefly pushed its market capitalization above $4 million before pulling back to $2.92 million, according to GMGN market data cited by BlockBeats on Sept. 12. The token’s theme centers on an "Anthropic pig" meme and has been tied to market attention around Long.xyz and its support, imminent or already live, for ANTHROPICx1L, a tokenized 1x long position linked to Anthropic. BlockBeats said ANTHROPIG can be traded as a pair against ANTHROPICx1L on Long.xyz. The platform operates on the Robinhood chain and focuses on a "stock-meme" model that links meme tokens with tokenized U.S. equities. Instead of pairing newly issued meme coins with conventional assets such as USDT or ETH, the platform allows pairs against on-chain stock tokens including NVDA, TSLA and AAPL. Part of the trading fees is directed back to a community treasury to accumulate the corresponding stock tokens. The report added that Anthropic has strong IPO expectations, but because it is not publicly listed in traditional markets, direct long exposure is not available there. In this setup, tokenized long products paired with meme tokens offer a speculative route on-chain. BlockBeats also warned that the tokens involved are highly volatile and carry significant uncertainty.
