Folliot was a central figure in a network of players operating on behalf of a match-fixing syndicate, an ITIA investigation found, and is the sixth player to be sanctioned as a result.
Folliot's career-high ranking was 488th, according to the ATP, and he earned prize money of $60,047 in singles and doubles.
The Frenchman denied 30 charges relating to 11 matches between 2022 and 2024, eight of which he played in, and an independent Anti-Corruption Hearing Officer, Amani Khalifa, upheld 27 of the charges in October.
Khalifa's written decision said the 26-year-old Folliot was "a vector for a wider criminal syndicate, actively recruiting other players and attempting to embed corruption more deeply into the professional tours".
Folliot, who was provisionally suspended in May 2024, has also been fined $70,000 and ordered to repay corrupt payments totalling more than $44,000.
Time served under the provisional suspension was credited against his period of ineligibility meaning Folliot's ban will end on May 16 2044, subject to repayment of outstanding fines.
