Elon Musk, who has been a key backer of Trump’s return to the presidency, was in his default wind-up mode as he used his X platform to post a superimposed picture of himself – holding a sink – inside the seat of US power.
Shares in Tesla, the electric carmaker which he leads as CEO and in which he owns a 13% stake, were up about 15% in pre-trading on Wall Street, implying a wealth gain of $15bn.
Dan Ives, an analyst at the US financial firm Wedbush Securities, said a Trump victory could add up to $200bn to the value of Tesla, which would increase Musk’s wealth by about $26bn.
Musk’s control of the network has enabled him to amplify his own pro-Trump messaging on the platform. His is the largest account, with more than 200m followers.
There is also likely to be a role for Musk in the Trump administration. In September Trump said he would form a government efficiency commission, with Musk leading it.
Musk has already indicated that a government efficiency body would help SpaceX, stating on X that his business could reach Mars sooner 'so long as it is not smothered by bureaucracy'.
Other Musk companies include the artificial intelligence startup xAI, which is reportedly heading for a valuation of $40bn, and the brain implant firm Neuralink, which is reportedly worth $8bn.
The wider US tech sector is expected to benefit as well in terms of regulation.
Musk is a figure of global fame and power already, but Trump underlined it on Wednesday.
That star is likely to get brighter, and more powerful, under a Trump administration.
