In an apparent rebuff to Donald Trump’s extroverted performance during the debate, shares of his social media company plunged to a record low on Wednesday morning.

Shares of Trump Media & Technology Group, Truth Social’s parent company, fell 17 percent to below $15.75 shortly after the market opened, surpassing the previous record low of $16.70 reached earlier this month.

The decline reduced Trump’s 60 percent majority stake in the company – 115 million shares – from $1.4 billion to $1.2 billion.

The volatile company’s share price has served as a gauge of fluctuating public confidence in Trump’s ability to win the 2024 presidential election over the past year.

Since its March IPO at $78 per share, which brought the company’s valuation to $7.85 billion, the stock has plunged more than 74 percent, but has rebounded 4 percent following a shaky debate performance by Joe Biden in June. According to SEC filings, Truth Social lost a staggering $58 million in 2023 before its IPO.

Wednesday’s decline came as even Republicans agreed that Kamala Harris had won Tuesday night’s debate, with Harris goading Trump into delivering confused, nonsensical tirades whose veracity was closely scrutinized by ABC News anchors.

However, Trump declared himself the winner on Truth Social.
