"Fox Business Network has canceled its sponsorship and participation in the Future Investment Initiative conference in Saudi Arabia", the network said in a statement. The Department of International Relations and Cooperation is reportedly unhappy about the meeting.
President Trump has been publicly asking to hear the recording.
The US president has been on the defensive ever since Khashoggi - a US resident and Washington Post contributor who had criticised Prince Mohammed - vanished on Oct 2 after visiting the Istanbul consulate.
Meanwhile, Turkish-language Sabah daily reported yesterday that a man who previously traveled with Saudi Crown Prince Mohammed bin Salman's entourage to the US entered the Saudi Consulate in Istanbul just before Khashoggi vanished there.
When asked about the consequences for those involved, Trump vowed they would be 'very severe'.

According to Turkey , he was then tortured, killed and dismembered. "His voice was a headache for the Saudi government ", said Abdulaziz.
It says reports on Mr Khashoggi's death are "completely false and baseless" and that it is "open to co-operation" to find out what happened.
The comments from Mevlut Cavusoglu, Turkey's foreign minister, came hours after President Trump said that it "certainly looks" as though Khashoggi is dead, and threatened "very severe" consequences if Saudi Arabia is found to have murdered him.
US intelligence officials have also intercepted communications between Saudi officials discussing a possible plan to detain Khashoggi.
ABC News also reported that "Turkish officials believe that Khashoggi was killed inside the Saudi consulate following a struggle that lasted eight minutes and they believe he died of strangulation".
The area became a target of the investigation after police focused on the vehicles which had left the consulate on the day Khashoggi disappeared, NTV channel reported.
In his brief comments to reporters, Pompeo also stressed the "longstanding strategic relationship" between the US and Saudi Arabia. Ankara's top diplomat, meanwhile, denied sharing any audio from the Saudi consulate with US officials.
"We need accountability" and for that a credible investigation is essential, he said. He said last week that it would be a "tough pill to swallow" to cease the sales over Khashoggi, contending that such a move would hurt the U.S. economy.
A source familiar with the Turkish investigation has told CNN that Saudi intelligence officer and former diplomat Maher Abdulaziz Mutreb played a "pivotal role" in the apparent assassination of Khashoggi. Khashoggi refused, and was killed. "I know what I'm going to do and I'm going to sanction the hell out of Saudi".
