Microsoft ended Tuesday's trading session at a record high of $360.53, following fresh optimism about growth from a key partner in artificial intelligence.
The major U.S. indices all posted gains for the day, with the S&P 500 notching its seventh-consecutive rise, while Microsoft delivered its eighth.
At an event in San Francisco on Monday, Microsoft's strategic AI partner, OpenAI, announced a slew of updates, including price cuts and plans to allow people to make custom versions of the ChatGPT chatbot.
Oppenheimer analysts, with the equivalent of a buy rating, said OpenAI's price updates confirm OpenAI's status as the category leader.
Microsoft said in a regulatory filing in October that OpenAI is its "strategic partner" on AI.
