<div id="readability-page-1">Elon Musk took his latest barb at former Microsoft CEO Bill Gates over his short position against the company, which the two have had some tensions over for a number of years. Gates admitted to Musk several years ago through a text message that he still held a short position against his sustainable car and energy company. Ironically, Gates had contacted Musk to explore philanthropic opportunities. <blockquote>Elon Musk explains Bill Gates beef: He ‘placed a massive bet on Tesla dying’</blockquote> Musk said he could not take the request seriously, especially as Gates was hoping to make money on the downfall of the one company taking EVs seriously. The Tesla frontman has continued to take shots at Gates over the years from time to time, but the latest comment came as Musk’s net worth swelled to over $600 billion. He became the first person ever to reach that threshold earlier this week, when Tesla shares increased due to Robotaxi testing without any occupants. Musk refreshed everyone’s memory with the recent post, stating that if Gates still has his short position against Tesla, he would have lost over $10 billion by now: <blockquote> Bill Gates placed a massive short bet against Tesla of ~1% of our total shares, which might have cost him over $10B by now — Elon Musk (@elonmusk) December 17, 2025</blockquote> Just a month ago, in mid-November, Musk issued his final warning to Gates over the short position, speculating whether the former Microsoft frontman had still held the bet against Tesla. “If Gates hasn’t fully closed out the crazy short position he has held against Tesla for ~8 years, he had better do so soon,” Musk said. This came in response to The Gates Foundation dumping 65 percent of its Microsoft position. <blockquote>Tesla CEO Elon Musk sends final warning to Bill Gates over short position</blockquote> Musk’s involvement in the U.S. government also drew criticism from Gates, as he said that the reductions proposed by DOGE against U.S.A.I.D. were “stunning” and could cause “millions of additional deaths of kids.” “Gates is a huge liar,” Musk responded. It is not known whether Gates still holds his Tesla short position. The post Elon Musk takes latest barb at Bill Gates over Tesla short position appeared first on TESLARATI.</div>
