The Grand Theft Auto 6 trailer features a fictional Dacity Coin, which is linked to an in-game brand called AudaCity. Leaked gameplay footage suggests that the protagonist, Lucia, may perform stunts to promote the coin to attract investment. Traders speculate that the asset could appear in multiple side missions or function as a tradable in-game currency similar to the stock market mechanics in GTA V.

Following the trailer release, speculators launched an unofficial Solana-based meme coin sharing the same name. The token reached a peak market capitalization of $15 million. One trader reported unrealized profits of $285 000 on an initial investment of $20 000 via the platform Pump.fun.

Despite the market activity, there are no official ties between the real-world Solana token and Rockstar Games. Traders are monitoring the game's scheduled release in November, anticipating that deeper integration of the fictional coin within the game could influence the value of the unofficial token.
