TradeSun sues OpenAI for trademark infringement over 'Astra' AI model name

On October 5, 2026, software developer TradeSun Inc. filed a trademark infringement lawsuit against OpenAI in San Francisco federal court, alleging that OpenAI's new GPT-6 Astra model infringes on TradeSun's registered "ASTRA" trademark used since 2021. TradeSun claims OpenAI's market saturation causes "reverse confusion," leading corporate clients to mistake TradeSun's established financial AI software for an OpenAI product. OpenAI dismissed the lawsuit as entirely meritless. This case follows previous trademark disputes OpenAI has faced over its "Sora," "Cameo," and "io" brand names.
