Mark Cuban issues stark warning over Kamala Harris' capital gains tax plan: 'Going to kill stock market'

WASHINGTON, DC: Billionaire investor and entrepreneur Mark Cuban recently voiced his strong opposition to Vice President Kamala Harris’ proposal to tax unrealized capital gains, a policy he believes could have devastating effects on the stock market.

While Cuban maintained that Harris would not actually implement this tax, his interview on CNBC’s 'Squawk Box' turned tense as the hosts questioned the viability of his claims, Fox News reported.

Mark Cuban claims Kamala Harris' capital gains tax will 'kill the stock market'

In a contentious interview, Mark Cuban openly disagreed with the concept of taxing unrealized capital gains, a proposal supported by both the Joe Biden administration and Kamala Harris’ campaign.

The idea behind this tax is to levy charges on investments that have appreciated in value but have not yet been sold, potentially hitting the wealthiest individuals the hardest.

During the interview, Cuban made his stance clear, warning, "What I told them is if you tax unrealized gains, you’re going to kill the stock market." He explained that such a tax would discourage companies from going public and ultimately drive many to seek refuge in private equity.

Cuban, known for his candid takes, further emphasized the challenges that early-stage businesses face. Many companies, while having significant equity, are "cash poor," meaning they lack the liquidity to cover hefty tax bills.

Reflecting on his own experience during the internet boom, Cuban said, "My net worth was enormous, but the number of dollars in the bank wasn't."

He explained that taxing unrealized gains would have forced him to borrow money just to pay taxes, hindering his ability to manage his company.

The tax on unrealized gains has become a hot-button issue as it directly impacts the top echelon of earners, particularly those who have made significant profits from investments without selling their assets.

Cuban’s argument echoed a broader concern among business leaders and economists who warn that such a tax could stifle innovation, discourage entrepreneurship, and create unnecessary financial burdens for companies during their most vulnerable stages.

Despite these concerns, Cuban maintained that Harris would not implement such a drastic measure. "They realize that's the issue," Cuban said, confident that Harris understands the potential consequences of this policy.

Mark Cuban stresses Kamala Harris' approach to taxation is about fairness

Mark Cuban also stressed that Kamala Harris’ overall approach to taxation is about fairness, noting that her "value proposition is we need to tax everybody fairly."

The interview took a confrontational turn when host Rebecca Quick pressed Cuban on the trustworthiness of Harris’ campaign promises. She pointed out that the vice president had not made a public statement quashing concerns about the unrealized gains tax, suggesting that the campaign may be playing both sides.

"My guess is that they're telling anybody who is donating to them exactly what they want to hear at this point," Quick said, before adding that what really matters is "what they say publicly and what they will stick to."

Cuban shot back, rejecting the notion that Harris was offering different messages to different audiences. "No, no, no, no, no. Absolutely, positively not," he responded emphatically, standing by his assertion that Harris’ position is rooted in a long-term strategy rather than mere campaign promises.

Quick continued to press the issue, urging the Harris campaign to be more transparent. "Say it publicly so we can hold you to it," she said. Cuban countered by arguing that Harris’ silence on the matter was due to the fact that it only affects a small portion of the population.

"This is not [a] number one priority for her," he said, explaining that the issue of taxing unrealized gains impacts less than 1% of voters. According to Cuban, Harris is more focused on promoting entrepreneurs and startups, rather than catering to the ultra-wealthy.
