"We can't be sure Theresa May is going to achieve her political objective of a landslide majority", he said. May has refused to do any live TV debates, and Corbyn had previously said he wouldn't take part without her.
Corbyn was joined at the debate by representatives of smaller parties, including Liberal Democrat leader Tim Farron and U.K. Independence Party chief Paul Nuttall.
Her decision to send senior minister Amber Rudd was "another sign of Theresa May's weakness, not strength", Corbyn said. "Don't give her yours".
"I think debates where the politicians are squabbling amongst themselves doesn't do anything for the process of electioneering".
"It's actually about getting out and about, meeting voters and hearing directly from voters", the prime minister said.
"Theresa May called this election because she is taking you for granted", said Leanne Wood, leader of the Welsh party Plaid Cymru.
It means the Tories' lead has fallen two points to 12.
But he said the outcome of the election was now in doubt.
If the YouGov model turns out to be accurate, May would be well short of the 326 seats needed to form a government tasked with the complicated talks, due to start shortly after the election, on Britain's divorce from the EU.
In contrast to signs from a string of opinion polls that have suggested May's Conservatives will increase their majority, the new constituency-by-constituency modelling by YouGov showed it might lose 20 of the 330 seats it holds and the opposition Labour Party could gain almost 30 seats, The Times said.
A later poll, a separate regular survey carried out by YouGov for Thursday's Times newspaper, showed May's Conservative Party just three percentage points ahead of the Labour opposition, which has been eating into her lead since the start of the campaign.
In the televised debate, Rudd accused Corbyn of having drawn up a "fantasy wishlist" manifesto paid for with a magic "money tree", and noting that most of his MPs backed a failed coup against him a year ago.
"Liar, Liar GE2017" by seven-piece band Captain Ska was released last Friday and now stands at number three, according to the Official Charts company.
