Tesla CEO Elon Musk sold $6.9 billion (€6.6 billion) worth of shares in the electric vehicle maker, saying the funds could be used to finance a potential Twitter deal if he loses a legal battle with the social media platform.
"In the (hopefully unlikely) event that Twitter forces this deal to close and some equity partners don't come through, it is important to avoid an emergency sale of Tesla stock," he said in a tweet late on Tuesday.
Shares of the microblogging site rose 3.5 per cent to $44.35 (€42.85) in early trading, but were still significantly below Musk's offer price of $54.20 (€52.35) per share. Tesla shares were up nearly 4 per cent at $882 (€852).
Musk in early July tore up his April 25 agreement to buy Twitter for $44 billion (€42.9 billion). Twitter has sued Musk to force him to complete the transaction, dismissing his claim that he was misled about the number of spam accounts on the social media platform as buyer's remorse in the wake of a plunge in technology stocks.
The two sides head to court on October 17.
Tesla stock sale a 'buying opportunity'
Following the announcement of the share sale on Tuesday, Musk took to Twitter and said "yes" when asked if he was done selling Tesla stock, adding he would buy it again if the Twitter deal does not close.
"The removal of the 'firesale' risk, the fact Musk has already raised cash in case of a Twitter decision going against him and the comment that he'll buy back stock if Twitter deal gets dropped all builds into a positive bias for Tesla," said Mark Taylor, a sales trader at Mirabaud Securities.
Tesla did not immediately respond to a Reuters request for comment, while Twitter declined to comment.
The stock sale comes shortly after Musk said at the company's annual general meeting that Tesla was a "buying opportunity".
"Elon's sale of (Tesla shares) over the past three days significantly increases odds the (Twitter) deal gets done, albeit at a slightly lower price $50-$51/share [€48-49]," Gary Black, managing partner of Future Fund LLC, said in a tweet.
Musk, the world's richest person, sold $8.5 billion (€8.2 billion) worth of Tesla shares in April and had said at the time there were no further sales planned.
But since then, legal experts have suggested that if Musk is forced to complete the acquisition or settle the dispute with a stiff penalty, he was likely to sell more Tesla shares.
Wedbush analyst Dan Ives said the likelihood of Twitter getting a settlement of $5 billion (€4.8 billion) to $10 billion (€9.6 billion) from Musk was starting to be factored into the social media company's stock.
Hints at Elon Musk's own social media company
Musk sold about 7.92 million shares between August 5 and August 9 and now owns just under 15 per cent of the automaker, according to Reuters calculations. The latest sales bring total Tesla stock sales by Musk to about $32 billion (€30.9 billion) in less than one year.
Musk also teased on Tuesday that he could start his own social media platform. When asked by a Twitter user if he had thought about creating his own platform if the deal did not close, he replied: "X.com"
He also tweeted that Tesla would begin shipping the longer-range and higher-cost version of its battery-powered Semi commercial truck this year.
The 500-mile range truck is expected to cost $180,000 (€173,900), although it would qualify for a tax break of up to $40,000 (€38,650) under a US subsidy program that was approved by the US Senate.
Tesla announced plans for the Semi in 2017 but its launch and volume deliveries to companies including PepsiCo Inc have been delayed by issues around the availability of the new 4680 battery cells.
Tesla shares have risen nearly 15 per cent since the automaker reported better-than-expected earnings on July 20.
