Sam Altman may be a billionaire and one of tech’s most influential leaders as the CEO of ChatGPT creator, OpenAI—but his communication style looks a lot like a Gen Z text chain: no capital letters, minimal punctuation, and an intentionally casual tone.
Internal text messages revealed through his legal dispute with Elon Musk show that Altman often sticks to all lowercase. This is true even at high-stakes moments, such as during the chaotic period in November 2023 when he was briefly ousted as CEO.
The stylistic choice stood in stark contrast to other tech power players in the same exchanges, like Microsoft CEO Satya Nadella and OpenAI chairman Bret Taylor, whose messages show more traditional attention to grammar and syntax.

A scroll through Altman’s social feeds today displays the same mix; some posts are formally structured, while others fail to include a single capital letter. It’s a habit he acknowledged on X back in 2023: “mildly interesting observation: i always use capital letters when writing by hand, but usually only type them when doing something that somehow reminds me of being in school.”
