Elon Musk arrived in Beijing on Wednesday, as his $150 billion lawsuit against OpenAI's Sam Altman played out. But a judge told Musk last month he may be recalled to a California courtroom for further testimony at the request of OpenAI lawyers.

Microsoft CTO Kevin Scott publicly addressed for the first time a 2018 email that Musk's lawyers have cited as evidence Microsoft knew OpenAI was abandoning its nonprofit mission. A confidential board memo filed in the case reveals how Microsoft's fear of falling behind Google drove the investment.

Elon Musk’s lawyer falsely suggested Altman was being investigated by the Senate, after it was instead a House lawmaker who contacted him.

A gag-gift trophy, an Elon Musk tantrum, and a Reid Hoffman name-drop figured prominently in the final day of testimony for Musk v Altman jurors.

Satya Nadella testified for roughly two and a half hours in the Musk v.
