OpenAI's ChatGPT has expanded its reach to an impressive 1.2 billion people every week, according to The Decoder. This rapid growth underscores the platform's increasing influence in AI-driven communication and productivity tools.

The Decoder also reports that OpenAI's annualized revenue rate is approaching $70 billion, marking a remarkable 70 percent increase since the start of Q3. This financial momentum positions OpenAI as a major player in the AI sector, alongside competitors like Anthropic, which reportedly maintains a similar revenue run rate.

For Japanese markets, this surge in AI adoption highlights growing opportunities in integrating advanced language models like ChatGPT and Codex into local FX, crypto, and equity trading platforms to enhance decision-making and automation.
