Microsoft stock reached a record high on Monday after the company said that Sam Altman, former chief executive of OpenAI, will join the company to head its artificial intelligence innovation leg. That comes after shares of Microsoft fell 1.7% on Friday, when Sam Altman was ousted from his position at OpenAI in a boardroom coup. Microsoft is the artificial intelligence firm’s biggest stakeholder, with a $13 billion investment in the company. Emmett Shear, former CEO of Amazon-owned streaming service Twitch, will replace OpenAI chief technology officer Mira Murati as interim chief executive. Microsoft shares are up about 56% for the year.
