Mark Cuban has praise for Harris' economic proposals and plenty of questions about Trump's

• Meanwhile, Cuban had some questions about Donald Trump's proposals.

Billionaire Mark Cuban has spent the past few days on social media defending Kamala Harris' economic proposals — while scratching his head over Donald Trump's plans.

Harris unveiled some of her policy proposals on Friday at a North Carolina rally. They include a federal ban on price gouging for groceries, a $25,000 subsidy for first-time homebuyers looking to make a down payment, and a $6,000 child tax credit.

So far, Cuban, who joined over 800 venture capitalists announcing their support for Harris in July, is gravitating toward her ideas.

In one post, Cuban argued the $25,000 down-payment subsidy could help homebuyers save money. In another, the billionaire supported the vice president's plan to ban price gouging on groceries, responding to a post from Bloomberg columnist Matthew Yglesias, who said that Harris "kind of vaguely said that antitrust enforcement is good (it is good)."

"This is a fact," Cuban said.

Meanwhile, Cuban raised several questions about former president Trump's economic plans, which include ending federal taxes on tips — a plan Harris also has supported — and tariffs on imports.

"Any importers want to explain how they deal with tariffs on say food and agricultural products," Cuban wrote on X in response to a clip of Trump blasting critics who view tariffs as taxing US citizens. Researchers at the Peterson Institute think tank said that Trump's proposed tariffs could cost Americans $500 billion annually.

Cuban also criticized Trump's plan to cool inflation.

In a speech on Wednesday, Trump said that he would "sign an executive order directing every cabinet secretary and agency head to use every tool and authority at their disposal to defeat inflation and bring consumer prices rapidly down."

"You just watch. They'll come down, and they'll come down fast," Trump said, promising results within the first 100 days he's in office.

In response, Cuban wrote: "What voters hear: He will instruct a bunch of un-named bureaucrats, and their agencies, talk to all the other un-named bureaucrats, and the thousands of bureaucrats that work for them, to defeat inflation in 100 days."

Overall, Cuban appears to be set on who he believes is the best "pro business candidate."

"I think she showed that she intends to be supportive of business. Particularly small business and entrepreneurs." Cuban wrote in an email to Business Insider. "She said she wanted regulatory clarity, which is important to the crypto market. And she is talking about transparency in healthcare."

"Of course, the devils in the details. But so far I like what I've heard," he wrote.
