The governor, he said, had assured him that he would take an "appropriate" decision as early as possible.
"We are 100 per cent confident that he will take a decision immediately," Yeddyurappa told reporters.
Earlier in the day, Yeddyurappa said he was confident of forming the government.
He also said Independent MLA Shankar had submitted a letter offering his support to the BJP.
Other party leaders echoed his confidence.
"People are with us," he said.
With the Karnataka assembly polls throwing up a hung verdict, the BJP with 104 seats has fallen short of the half-way mark of 112.
The Congress-JD(S) combine moved quickly even as the counting of votes was underway yesterday and requested the governor to allow formation of a JD(S)-led government. The two parties together have a clear majority in the 224-member Assembly.
Elections were held for 222 seats on May 12 while polling for the remaining two will be held later.
