I'll include some sources, which led to my question. However, I'm not declaring these sources to be accurate:

Lucky Luciano, by Tim Newark
None of Lanky's closest friends went to the meetings. What he did was tip off the local sheriff about the meetings.

It fact, some have asserted that the Apalachin
Conference of 1957 was called to crown Genovese as
the new boss of bosses....
A police raid broke up the
meeting, and strong evidence later showed the con-
ference was sabotaged by an alliance of Lansky,
Luciano (from exile in Italy) and Frank Costello — all
three not present at the meeting — and Carlo Gam-
bino...

According to statements attributed to Luciano, Gam-
bino had gone there in case the meeting somehow
proceeded, planning to denounce Genovese's ambi-
tions and to refuse to hand him any envelope of
money as a symbol of his authority.

This did not stop the press from calling Genovese
the boss of bosses, but if he was, his reign was to
prove even less enduring than that of the unfortunate
Maranzano.

The fact that Vito Genovese became the emperor caught
without his clothes and was destroyed at the meeting
suggests a setup. Through hindsight — and the revela-
tions made by such figures as Lucky Luciano and
Doc Stacher that the police were tipped off and the
meeting sabotaged — it became almost impossible to
reject insider foul play.

Newspaper speculation suggested that the
Apalachin meeting was intended as a forum for
presenting Genovese with his "boss of bosses"
crown. Much was also made of the fact that a total
of $300,000 was found on the arrested crime
bosses; "envelope money" perhaps to be given to
Genovese? More likely the money was a total of
typical fat wads carried by dons. And Carlo Gam-
bino did make it known that he brought no money
for Genovese.

Last Testament of Lucky Luciano
"I told Carlo to go to the meet, but not to bring no envelope. He took my advice....he told me later, that if things had come to a showdown, he was gonna stand up up and tell Vito to go to hell, that he didn't have the chance of a snowball in hell that the council would name him top capo"- Luciano
