"Rs 100 crore, Rs 200 crore figures are imaginary. The BJP is not doing anything. This is the kind of politics the JD(S) and Congress play," he told reporters.
The union minister also accused the Congress and JD(S) of having come together by "unholy means."
Mr Javadekar, who is in the state as the BJP makes an aggressive bid to come to the power after the poll results threw up a hung assembly, said his party was not in the practice of horsetrading and exuded confidence it will form the next government.
"We are not in the habit of horsetrading of any kind and therefore we are going by the rule book, and we are forming the government.
"That is our confidence.We have already met the Governor (Vajubhai Vala) and submitted our plea and we are very sure to form government, a very stable government," he added.
"If somebody is approaching court or anything... It is within the parameters of a democracy," he said.
Earlier in the day, Mr Kumaraswamy claimed that the BJP was trying to "bribe" its way to power through "horsetrading" after falling short of majority.
"Our MLAs were offered Rs 100 crore by the BJP to break away. I want to know whether this is black or white money," he told a press conference.
