AI-linked meme tokens tied to public equities and tokenized long positions posted steep 24-hour losses on Sept. 13, according to GMGN data cited by BlockBeats. Artificial Inu (AI), paired with Nvidia stock, fell 27% and was valued at $247 million. MOO, tied to Micron, dropped 37% to a $18 million market cap. Microduck, also linked to Nvidia, lost 26% and stood at $7.3 million, while FLYBRAIN, paired with Google stock, slipped 23% to $9.6 million. UBIK, described as a suspected AI project created by the developer behind aixbt, declined 25% to a $28 million valuation. ANTHROPIG fell 44% to $5.4 million and trades against ANTHROPICx1L, a tokenized 1x long Anthropic position. CATGPT dropped 22% to $6.7 million and trades against OPENAIx1L, a tokenized 1x long OpenAI position. The move came after Anthropic CEO Dario Amodei said the industry must slow the pace of improving AI model capabilities, adding that slower progress does not mean stopping training or technical advancement but allowing enough time for alignment and model protection. OpenAI founder Sam Altman said he agreed.

Long.xyz co-founder Nate said the platform’s new pre-IPO pairs posted $18 million in 24-hour volume for the OpenAI pool and $14.6 million for the Anthropic pool, calling it the project’s biggest release so far. But BlockTempo’s on-chain check found the underlying market was far smaller. The wrapped tokens track 1x long perpetual positions on Lighter, where the OpenAI perpetual saw only $68,000 in 24-hour volume and the Anthropic market logged $233,000 over the same period. At publication, the main OPENAIx1L/USDG pool on Robinhood Chain had $354,000 in liquidity and $20.01 million in 24-hour volume, while the ANTHROPICx1L/USDG pool had $371,000 in liquidity and $15.54 million in volume. That translated into turnover of 56.6x and 41.9x in a single day. BlockTempo said the widely shared 15,193.60% and 9,583.99% annualized yields were derived by annualizing one day of fee income against a very small TVL, producing a snapshot figure rather than a sustainable yearly return. The report also found price fragmentation across pools. OPENAIx1L traded between $1.071 and $1.17 across at least eight USDG pools, while ANTHROPICx1L ranged from $1.0093 to $1.27.

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.
