Donald Trump sent shares of his social media startup soaring on Friday after he said at an event that he has “absolutely no intention of selling” his shares.

Trump Media stock shot up more than 25% after majority owner Donald Trump said he is not selling his shares. The Republican presidential nominee will soon be free to start cashing in his nearly 57% stake in the company that trades as DJT on the Nasdaq.

The company behind the Truth Social platform is worth more than $3.5 billion on Wall Street, and Trump owns more than half of it. So far, Trump and other insiders in the company known as TMTG have been unable to cash in because a “lock-up agreement” has prevented them from selling any of their shares since TMTG began trading publicly in March.
