Elon Musk's AI startup xAI has merged with social network X in an all-stock deal valued at $45 billion, according to CNBC. Musk said the combination will unify data, models, computing, distribution, and talent to unlock potential. Both companies are privately held, and investors in X will likely receive xAI shares. Musk founded xAI in 2023 to understand the universe and has positioned it as a direct competitor to OpenAI, which he co-founded in 2015. Musk later left OpenAI and is publicly clashing with the company and its CEO, Sam Altman, over its current direction.
