Trading in the owner of Donald Trump’s Truth Social was suspended several times on Wall Street on Tuesday as extraordinary volatility engulfed the small social media empire’s shares ahead of next week’s election.

Trump Media & Technology Group (TMTG) rose 14% in early trading on Tuesday before quickly reversing all its gains. By late morning the price had risen 1.5%.

The stock has soared in recent weeks, tripling its value this month alone as Trump wooed voters during the final stages of the presidential campaign.

TMTG is now valued on the stock market at around $9 billion, and in October has at times overtaken the estimated valuation of X, formerly Twitter: a much larger social network than Truth Social, which was acquired by Trump ally Elon Musk two years ago .

The former president’s majority stake in TMTG is currently worth about $5.1 billion on paper, after a wild ride in the market this year.

The young company staged a remarkable rally this spring, joining the ranks of so-called “meme stocks” like video game retailer GameStop, which roiled Wall Street by staging unexpected, volatile rallies as day traders flooded in.

However, like GameStop, TMTG’s spike during the rapid rally set the stage for an almighty crash. The group’s shares, which rose above $66 in March, fell to $12.15 last month.

But with presidential election polls closely tied and betting markets putting Trump ahead in the race, TMTG rebounded. The market valuation has quadrupled since the company’s shares bottomed in September.

Truth Social, in the spotlight on Wall Street, remains a very small social network. According to Similarweb, it was visited 13.5 million times last month. X received 706.2 million visits over the same period.
