Microsoft stock price: MSFT faces Musk’s $134 billion claim ahead of Jan. 28 earnings
New York, Jan 17, 2026, 09:35 EST — Market closed. Microsoft shares are heading into next week with a new legal cloud looming. Elon Musk claims he’s after as much as $134 billion from OpenAI and Microsoft over what he calls “wrongful gains.” Musk told a federal court that OpenAI made between $65.5 billion and $109.4 billion, while Microsoft pulled in $13.3 billion to $25.1 billion from his early backing. The case is set for a jury trial in April. Friday’s session saw MSFT gain 0.7%, closing at $459.86, though it’s still down roughly 3.6% on the week.
