Born in Baeza, Olid grew up in the household of the governor of Cuba, Diego Velázquez de Cuéllar. In 1518 Velázquez sent Olid to relieve Juan de Grijalva, but en route, a hurricane caused the loss of Olid's anchors, and he returned to Cuba. On January 10, 1519, Olid sailed with Hernán Cortés's fleet, as his quartermaster, and took an active part in the conquest of the Aztec Empire. He fought at the Battle of Otumba on 14 July 1520,
In 1523, Cortés made Olid the leader of an expedition to conquer Honduras, but while resupplying in Havana, Olid (at a suggestion by Velázquez) declared his independence from New Spain and set out to conquer Honduras for himself. Landing east of Puerto Caballos, he founded the settlement of Triunfo de la Cruz. Many of Olid's supporters moved to Naco, where there was good agricultural land and gold. When Cortés learnt of Olid's rebellion, he sent Francisco de Las Casas against Olid with two warships. Even though both these ships were destroyed in a storm and many of his soldiers defected to Olid, Las Casas defeated Olid in battle and captured him.
Accounts of how Olid died vary; Bernal Díaz del Castillo asserts in his Verdadera Historia de la Conquista de Nueva España that Las Casas had him beheaded at Naco, while Antonio de Herrera y Tordesillas wrote that Olid's soldiers rose against and then murdered him.
