Although Trump has vowed not to sell, the stock has tumbled as insiders like Truth Social's co-founders are free to cash out.

Trump Media & Technology Group Corp.’s stock dropped to its lowest level since it went public in March Friday, as a ban on stock sales lifted.

Shares of Trump Media have slumped to new lows on the first trading day that its biggest shareholder, former President Donald Trump, is free to sell his stake in the company behind the Truth Social platform.
