According to @OpenAI, DevDay 2025 starts tomorrow and Sam Altman’s keynote will be streamed live, as stated in an official post on X dated Oct 5, 2025 (source: OpenAI on X, Oct 5, 2025). The post also states "New ships" but provides no product specifics, pricing, or timing beyond the event start and keynote stream (source: OpenAI on X, Oct 5, 2025). For trading calendars, this confirms a scheduled AI event window beginning the day after the post date (Oct 6, 2025), useful for headline monitoring across AI-exposed equities and crypto sectors even though no crypto details were included in the announcement (source: OpenAI on X, Oct 5, 2025).
