The US Green Party led by Jill Stein has dropped a court case seeking a state-wide recount in Pennsylvania.
A court filing said Green Party voters could not afford the $1m (£785,000) bond ordered by the court by Monday.
Ms Stein has tried to force recounts in Michigan, Wisconsin and Pennsylvania, three states narrowly and unexpectedly won by President-elect Donald Trump.
But Trump supporters tried to block the recounts, which are unlikely to change the polls results if they take place.
The Greens’ decision comes two days before a court hearing was scheduled on the case, in the state where Donald Trump’s margin of victory was 49,000, or less than 1%.
“Petitioners are regular citizens of ordinary means. They cannot afford to post the $1,000,000 bond required by the court,” read a court filing.
