The social media giant and the Tesla CEO are expected to appear in court in October in a legal battle over the latter's takeover bid.
ADVERTISEMENTTwitter Inc on Thursday dismissed Elon Musk's claims in a Delaware court filing that he was hoodwinked into signing the deal to buy the social media company, saying that it was "implausible and contrary to fact".
Musk made the claims in a countersuit filed under seal last Friday, which was made public on Thursday.
"According to Musk, he - the billionaire founder of multiple companies, advised by Wall Street bankers and lawyers - was hoodwinked by Twitter into signing a $44 billion [€42.9 billion] merger agreement. That story is as implausible and contrary to fact as it sounds," the filing released by Twitter on Thursday said.
Twitter's filing is the latest salvo in what is building up to be an increasingly acrimonious legal showdown between the world's richest person and the social media giant.
The two sides head to trial on October 17 after Musk sought to abandon his deal to acquire Twitter over what he says is a misrepresentation of fake accounts on the site.
The San Francisco-based tech company is trying to force Musk to follow through on the deal and accuses him of sabotaging it because it no longer served his interests.
A representative for Musk did not immediately respond to Reuters' request for comment.
In the counterclaims made public on Thursday, Musk accuses Twitter of stepping up efforts to conceal the true number of its users, as the market plummeted.
"As a long bull market was coming to a close, and the tide was going out, Twitter knew that providing the Musk Parties the information they were requesting would reveal that Twitter had been swimming naked," the counterclaims say.
Twitter counters that Musk has not "pleaded a shred of evidence" for these "fact-free" allegations.

Musk also claims that "Twitter’s misrepresentations run far deeper than simply providing incorrect numbers" about its spam or false accounts.
While "Twitter touts having 238 million 'monetizable daily active users,' those users who actually see ads" is roughly 65 million lower, Musk says in the counterclaims.
Twitter maintains that its SEC disclosures about monetisable daily active users were accurate.
Musk, the chief executive of electric car company Tesla Inc, offered to buy Twitter for $54.20 (€52.96) per share in April, saying he believed in its potential as a global platform for free speech.
But he soured on Twitter as its stock price lagged his takeover bid, and began expressing skepticism that bot and spam accounts represented less than 5 per cent of users.
Musk sought to back out on July 8 without paying a $1 billion (€977 million) breakup fee, citing Twitter's failure to provide details on bot and spam accounts.
Twitter sued him four days later.
Earlier this week, Twitter issued dozens of subpoenas to banks, investors, and law firms that backed Musk's takeover bid, while Musk issued subpoenas to Twitter's advisers at Goldman Sachs and JP Morgan over their work.
ADVERTISEMENTLegal experts have said Twitter's requests suggested the company wanted to know why Musk turned against it, or whether he reneged on his obligation to obtain sufficient financing.
