A pseudonymous trader known as @3i claims to have made over $6 million by anticipating the listing of two memecoins on Robinhood's platform. The trader and their group achieved this by monitoring code changes in BitGo's public repository and tracking Wintermute's onchain activity.
The key breakthrough came when a BitGo developer opened a pull request on July 27, which included a code change adding the Cash Cat token to Robinhood Chain. This was later confirmed by a BitGo code update on July 29, which also added support for 99 Robinhood Chain stock tokens. The trader interpreted this as a strong signal that Robinhood was behind the request.
Wintermute provided the final confirmation when it approved the trading pool for Cash Cat on August 3. The trader then began buying the memecoin aggressively, accumulating around 4% of its supply. Onchain data reviewed by The Block supports parts of this timeline, though the profit figures could not be independently verified.
The trader also claimed to have repeated the strategy with the PONS token, making an additional $2 million. However, they noted that the advantage has since faded, and the September 2 listing of PONS appeared to be a honeypot set by Robinhood to catch insiders.
