FABLE, a meme coin on Robinhood Chain, surged more than 990-fold in 24 hours and briefly exceeded $10 million in market capitalization. The token was linked to an experimental project in which the AI agent Claude Fable 5 built a website and issued a token after an open-ended prompt from AI artist and designer Kevin Ngo. FABLE’s market capitalization then fell more than 90% in two minutes after Ngo said his social media account had been hacked and that he did not endorse any token. It briefly reached $452,400, rebounded above $2 million in about 10 minutes, and later fell again to about $560,000 after Ngo repeated his denial. Earlier market data had cited a market capitalization of $1.54 million after a low of $760,000, alongside $11.7 million in 24-hour trading volume. The episode illustrates the extreme volatility and credibility risks surrounding meme coins.
