Assange's British lawyer, Mark Stephens, said he had about half the amount raised by Wednesday, despite getting pledges for donations from British and American celebrities,.
Meanwhile, court officials said an appeal against the decision to grant him bail would not be heard for another 24 hours.
Officials said the appeal by Swedish authorities would be heard at 1130 a.m. Thursday by a senior judge, Duncan Ouseley.
On Tuesday, a judge, but Swedish prosecutors .
Assange has spent a week in prison following his surrender to British police over a Swedish sex-crimes warrant. He denies any wrongdoing but has refused to voluntarily surrender to Sweden's request to extradite him for questioning.
Supporters of the 39-year-old Australian say the charges are trumped up and possibly politically motivated.
Stephens said Wednesday that "somebody has it in for Julian Assange and we only can conjecture why."
But lawyer Gemma Lindfield, acting for Sweden, told Tuesday's hearing that Assange faced serious allegations and may abscond if granted bail.
She said he is accused of rape, molestation and unlawful coercion by two women for separate incidents in August. She said one had accused him of pinning her down and refusing to use a condom. A second woman says Assange had sex with her without a condom while he was a guest at her Stockholm home and she was asleep.
Assange has not been charged in Sweden. His lawyers say the allegations stem from a dispute over "consensual but unprotected sex" and argue that he has offered to make himself available for questioning via video link or in person in Britain.
LIndfield also rejected attempts to link Assange's case with the work of WikiLeaks - which last month deeply angered U.S. officials by beginning to publish its trove of 250,000 secret U.S. diplomatic cables.
"This is not a case about WikiLeaks, rather a case about alleged serious offenses against two women," Lindfield said.
District Judge Howard Riddle approved bail on condition Assange wear an electronic tag, stay at a specific address in southern England, report to police every evening and observe two four-hour curfews each day in addition to putting up the bond.
