Shareholders to decide this week whether to grant Musk, the world's richest person, one of the richest compensation packages in corporate history.

The electric-vehicle company, which aims to pivot into AI and robotics, is set to hold its annual shareholder meeting on Thursday; Its board is asking investors to vote for a plan that includes a CEO performance pay package potentially worth $1 trillion to Elon Musk.

Mr. Musk’s supporters say he may quit if shareholders don’t approve a trillion-dollar package. Some investors say it’s excessive and would give him too much sway.
