CNBC Daily Open: Most people don't start a political party after separation

• Tariffs will kick in Aug. 1, U.S. President Donald Trump confirms.
• U.S. stock futures slipped Sunday.
• OPEC+ members agree to increase oil output.
• Elon Musk forms a new political party.
• Wall Street is growing cautious on European equities.

When they find themselves without a significant other, most men finally start living: They pay attention to their personal grooming, hit the gym and discover new hobbies.

What does the world's richest man do? He starts a political party.

Last weekend, as the United States celebrated its independence from the British in 1776, Elon Musk enshrined his sovereignty from U.S. President Donald Trump by establishing the creatively named “American Party.”

Few details have been revealed, but Musk said the party will focus on “just 2 or 3 Senate seats and 8 to 10 House districts,” and will have legislative discussions “with both parties” — referring to the U.S. Democratic and Republican Parties.

It might be easier to realize Musk's dream of colonizing Mars than to bridge the political aisle in the U.S. government today.

To be fair, some thought appeared to be behind the move. Musk decided to form the party after holding a poll on X in which 65.4% of respondents voted in favor.

Folks, here's direct democracy — and the powerful post-separation motivation — in action.
