Following the first presidential debate, betting odds for a Kamala Harris presidency just got higher, while Donald Trump's company (DJT) takes the blow.

As reported by Reuters, DJT, which owns Truth Social, suffered a 15% decrease in shares during premarket trading. This is not the first time a huge decline welcomed Trump Media, as it already slumped almost 60% in July after Harris replaced Biden as the Democrat candidate.

At the same time, bet pricing for a Trump victory was also down to 47  cents, compared to Harris' 57 cents. 

To make it worse for Trump, Kamala Harris also earned an endorsement from Taylor Swift. The megastar posted on her 280 million Instagram followers that she will vote for Harris and Walz this November, with a jab at JD Vance's 'childless cat lady' remark.

Trump Media Expected to Lose Mooney

Now, the question is whether the Trump Media's shares will consistently go down as more endorsements are expected to come out and debates are lined up. Reuters also noted that while its market value jumped to nearly $9.2 billion, the stock has since been down 76% after that peak, which was around a failed assassination attempt.

Unfortunately for Trump, he's not allowed to sell shares if the stock price goes below $12 in the next 20 trading days. It's currently $15.73 and a slump is more expected. Once Trump begins offloading shares, the supply of shares will also increase.

"If he wins (the election) he doesn't have to sell his shares and DJT can grow into something. If he loses, he has to sell his shares to pay legal bills and it is unlikely DJT is a going concern," a capital asset management CEO told Reuters.
