"I am thankful to the people of the state for reposing faith in us again, and all the allies for working hard for this victory," said Fadnavis, taking care to downplay his party's prominence.
Though the BJP's tally has fallen this time, there is no substantial increase in the strength of the opposition parties, Fadnavis said, adding that peoples' expectations may have increased.
"We accept the verdict of the people. There is little doubt that we would be forming the next government with the support of all our allies," Fadnavis asserted.
At a separate media briefing, Thackeray reminded the BJP of the pre-Lok Sabha elections understanding of a 50:50 power-sharing formula, including sharing the post of Chief Minister.
"There is no hurry to form the government," Thackeray said, indicating that he would consider all options after the final results are declared.
Earlier on Thursday, Sena MP Sanjay Raut had raised the similar demand of 50:50 power-sharing ratio as was decided with the top BJP leadership.
"There will be no change in the situation. Even the post of Chief Minister has already been decided with the Sena leaders. There will be a 'Maha-Yuti' government soon," Fadnavis said, dismissing speculation that the Sena might explore options.
The statement came shortly after Congress MP Hussain Dalwai offered the party's support to Sena if it was ready to form the government.
