Kai Zachary Perlado Sotto (English: /ˈkaɪ/, Tagalog: [ˈkaɪ ˈsɔtɔ]; born May 11, 2002) is a Filipino professional basketball player for Koshigaya Alphas of the Japanese B.League.

He played high school basketball for the Ateneo Blue Eaglets of the University Athletic Association of the Philippines (UAAP), winning the juniors' division championship and MVP award.

He then moved to the United States, where he was recruited by several NCAA Division I schools, but decided to forgo his college eligibility and signed with NBA G League Ignite in 2020.

However, due to COVID-19-related travel restrictions and his decision to play for the Philippine national team at the 2021 FIBA Asia Cup qualifiers, Sotto left Ignite by mutual agreement.

He then joined the Adelaide 36ers of Australia's National Basketball League (NBL) for the 2021–22 season, after which he declared for the 2022 NBA draft but went undrafted.

[5][6] In March 2019, Sotto left Ateneo as a third-year high school student to move to the United States in an attempt to advance his basketball career.

[7] In the United States, he continued his studies at the Miami School in Hamilton, Ohio while simultaneously dealing with commitments with The Skill Factory and NBA G League Ignite.

[19] On January 21, 2020, Sotto was named MVP of the King Invitational tournament, averaging 27 points, 10.6 rebounds, 4.3 blocks and three assists in three games.

[20] On February 15, 2020, he participated in the Basketball Without Borders Global Camp held during NBA All-Star Weekend in Chicago.

However, Sotto was expected to miss several games with Ignite after he opted to play for the Philippine national team at the 2021 FIBA Asia Cup qualifiers given by logistical issues caused by COVID-19 pandemic-related travel restrictions.

[27] Despite being able to return to the United States, the NBA G League announced that it has reached a "mutual decision" that Sotto would not be able to rejoin Ignite.

[32] On January 30, 2022, Sotto recorded 12 points, four rebounds, and one assist in 21 minutes of play, in an upset victory, 88–83 over the reigning champions and top-seeded Melbourne United.

[52] On January 5, 2025, Sotto tore his left anterior cruciate ligament (ACL) in a 79–77 loss to the SeaHorses Mikawa and will be sidelined for an extended period of time as a result.

[54] In April 2018, he represented the Philippines at the FIBA Under-16 Asian Championship in Foshan, China, where he led his team to fourth place.

[57] Sotto played for the Philippines at the 2018 FIBA Under-17 World Cup in Argentina, where he averaged 16.4 points, 10.6 rebounds and 2.3 blocks per game.

[59] Sotto was supposed to make a debut with the senior national team at the 2021 FIBA Asia Cup qualifiers in early 2021 and went to the Philippines.

However, due to logistical issues and abrupt hosting changes for the qualifiers caused by the COVID-19 pandemic, Sotto had to return the United States to rejoin Ignite.
