Following the withdrawal of Marussia and Caterham, who have both entered administration since the last Formula One race in Russia, newspaper reports suggested that Lotus, Sauber and Force India would also pull out in in protest at the current costs involved in the sport.
However, Lotus took to Twitter to assure fans that both Romain Grosjean and Pastor Maldonado will be on the grid on Sunday in Texas.
"For an absence of doubt, we will be racing on Sunday. That's kinda why we're here," they posted.
Speaking at Friday's team principal press conference, Lotus co-owner Gerard Lopez said: "Now is the time to say things as they are. Number one – the distribution of all the revenues is completely wrong.
"Whether the size of what is distributed or not is debatable, but when you have teams getting more money just for showing up than some teams spend in an entire season something is entirely wrong with the system. So that cannot be allowed to happen.
"And now is not the time to be talking about, but to be acting about it, so we will see what happens in the next couple of weeks."
With the outlook looking bleak for Marussia and Caterham, F1 supremo Bernie Ecclestone admits there could be as few as 14 cars on the grid next season.
"It could go down to 14," he told Sky Sports. "If we lose another two teams that is what will happen.
"I can't predict if it won't or it will. But if it is 18, no drama at all."
Asked whether he believed F1 needed small teams, Ecclestone responded: "We need them if they are going to be there performing properly and not moving around with begging buckets."
The US GP experienced a boycott in 2005, when only six cars took part following a dispute over tyres at one of the most controversial races in the sport's history.
