FLYBRAIN, a memecoin on Robinhood Chain, briefly reached a market capitalization of $54.61 million before falling to about $30 million, GMGN data showed. The token rose more than 90-fold over six hours, adding to earlier reports of a 302% one-hour gain, a market value of $27.26 million and an intraday increase of more than 670-fold. Its price movements coincided with attention linked to Marc Andreessen, who had followed FLYBRAIN developer Fruit Fly Dev on X. FLYBRAIN draws on a fruit fly brain connectome map released by Google and Janelia on September 3, using mapped buy and sell activity as sensory inputs to autonomously place orders and issue tokens.
