On Monday, April 27, the trial of Elon Musk's lawsuit against OpenAI and its key investor Microsoft will begin in a California court. The conflict between the two co-founders of the AI company - Musk and its head Sam Altman - could affect not only the future of the startup itself, but also the balance of power in the entire AI industry, Bloomberg <a href="https://www.bloomberg.com/news/articles/2026-04-24/why-did-elon-musk-and-sam-altman-fall-out-what-is-their-court-case-about">believes</a>. If Musk wins, it could cost OpenAI a significant sum and lead to a major overhaul of the loss-making AI giant. But regardless of the outcome, the case has already created uncertainty around OpenAI's business as it confronts increasing competition and prepares to go public, the agency notes.
