In his own poll, Zelensky asked users if they liked the world's richest person more when he supported Ukraine.
President Vladimir Putin has already declared four Ukrainian regions to be part of Russia, following the so-called referendums denounced by Kyiv and its Western allies as fraudulent. Russia does not control all of the four regions.
The world's richest person in 2022, according to Forbes magazine, cautioned that the conflict could end in nuclear war, but Ukraine's Foreign Minister Dmytro Kuleba said in a tweet: "Those who propose Ukraine to give up their people and land - presumably not to hurt Putin's bruised ego or to save Ukraine from suffering - must stop using the word 'peace' as an euphemism to let Russians murder and rape thousands more innocent The BBC is not responsible for the content of external sites, but it is worth noting that a possible, albeit unlikely, outcome from this conflict is nuclear war - Elon Musk, October 3, 2022. The Kremlin welcomed Mr Musk's suggestions. It is very positive that somebody like Elon Musk is looking for a peaceful way out of this situation, said spokesman Dmitry Peskov.
Zelensky responded with his own poll asking : Which elonmusk do you like more? One who supports Ukraine or one who supports Russia. The poll had been voted on more than 1.5 million times after it was posted.
That gained the popularity of Musk in Ukraine and was invited by Mr Zelensky to visit when the war with Russia ended.
The businessman posted a poll on a busy week when he is due to give evidence to lawyers acting for Twitter ahead of a trial set to begin on October 17th. Twitter is suing Mr Musk after he walked away from a $44 billion deal to buy the social media platform.
