• Shares of Trump Media fell to a new 52-week low Friday, closing down 7.82% just one day after lockup restrictions expired.
• Until now, the lockup provision had prevented TMTG's majority shareholder, former President Donald Trump, and other early investors from selling their shares.
• The company has acknowledged in regulatory filings that the end of the lockup could spur large sales of the company's stock.

Shares of Trump Media fell to a new 52-week low Friday, closing down 7.82%, at $13.55 per share, just one day after "lockup" restrictions expired, which had previously prevented its majority shareholder, former President Donald Trump, and other early investors from selling their shares.

Trading volume was heavier than average on Friday, with nearly 20 million shares changing hands before the closing bell. The closing price for DJT took extra time to pinpoint, as high trading volume resulted in delayed settling. 

Trump Media's market cap stood at $2.7 billion at Friday's close.

But it will likely be several days before public filings with the U.S. Securities and Exchange Commission reveal whether this volume is due to early investors selling shares now that the lockup period is over, or merely a higher-than-average number of retail investors trading the stock.

The lockup agreement first took effect when Trump Media went public in March, following a merger with a blank-check firm called Digital World Acquisition Corp., or DWAC.

The company has acknowledged in regulatory filings that the end of the lockup could spur large sales of the company's stock, which trades under the ticker "DJT."

But even if insiders were not the ones selling, the company has said that a perception by the markets that a sell-off was underway might drive down DJT's stock price.

Trump, whose 114,750,000 share stake in Trump Media was worth $1.5 billion at Friday's close, said last week that he would not sell his shares when the restrictions lifted.

"I have absolutely no intention of selling," he said at a press conference in California on Sept. 13.

The Republican nominee's announcement caused the stock to surge, climbing as much as 25% before closing up more than 11%. But DJT's slump this week has erased those gains.

Trump Media on Friday closed at its lowest closing level since debuting on the Nasdaq in March, closing the day at a price of $13.55 per share. The slide puts shares down more than 20% from where it opened the week.

Its intraday low came shortly after 10 a.m. ET, when the share price dropped to $13.50 — a level not seen since July 2023, when the stock was still DWAC.

Friday's sell-off extended DJT's monthslong slump, which has seen the stock fall more than 65% since its most-recent high in July. That surge was prompted by a bump in Trump's electoral odds after he survived an assassination attempt at a campaign rally in Pennsylvania.
