- An Ethereum-based gaming network called Xai has filed a federal lawsuit against Elon Musk’s xAI, alleging trademark infringement and unfair competition.
- Ex Populus, the company behind Xai, claims that Musk’s brand has caused widespread confusion, and that the damage has been magnified by his company’s recent entry into the gaming sector.
- The complaint states that Musk’s lawyers have threatened to challenge the Xai trademark and that even xAI’s own chatbot, Grok, has mistakenly conflated the two companies.
Elon Musk’s AI brand xAI is now facing a federal trademark lawsuit with a gaming network that says his brand basically destroyed its identity.
The Ethereum-based blockchain gaming protocol is called Xai, and is run by the Delaware-based firm Ex Populus, which filed the suit in the Northern District of California.
In it, the firm accuses Musk of trademark infringement and unfair competition, claiming it has operated under the XAI name since mid-2023 with its $XAI token, and a gaming ecosystem built on-chain.
Musk’s arrival with “xAI” last year, and his November 2024 announcement of a gaming studio under the same label, sent the market into chaos, the protocol claims.
Ex Populus took legal action today to protect the Xai brand. With increased confusion around Elon Musk’s AI company (@xai), it’s a big responsibility to safeguard the brand that the community trusts. You can read more details at https://t.co/ce8Aw9hNCZ

Trademark Pressure
The complaint points to misreporting by media outlets, user confusion, and even Musk’s own chatbot Grok wrongly conflating the ventures.
Ex Populus says the damage is twofold; first, the dilution of its brand and collateral backlash from Musk’s polarizing reputation. The filing notes “significant negative consumer sentiment” spilling over onto Xai purely from the mistaken association.
Second, it claims Musk’s lawyers tried to strong-arm them earlier this month by threatening to wipe their registration, while the US Patent and Trademark Office has already frozen several of Musk’s applications on likelihood-of-confusion grounds.
Ex Populus wants the court to cancel xAI’s pending trademarks, block Musk’s company from using the name in gaming and blockchain, and extract damages. In its words, “there is no remedy at law for the sheer magnitude of harm Defendants have caused.”
What began as Musk naming yet another company with an “X” now sits in federal court, where the judge must decide whether the Tesla CEO’s brand sprawl can steamroll a much smaller crypto gaming project (which is quite a possible outcome based on previous cases involving Musk and trademark “issues”), or whether this time the X is one too many.
