No - there was no slavery in the new territories - California or New Mexico or Utah. Texas was a slave state already.
If slavery was not permitted in the Mexican cession, pro-slavery southerners ambitiously sought to expand their slave holding territories into Latin America.

David Wilmot, a Democratic congressman from Pennsylvania, proposed the Wilmot Proviso in 1846, which sought to ban slavery in the territories acquired from Mexico as a result of the Mexican-American War.

the Mexican cession was the result of war with Mexico.
In 1850, two key proposals were made to address the issues of slavery in the territories acquired from the Mexican Cession. The first was the Compromise of 1850, which included the admission of California as a free state and allowed the territories of New Mexico and Utah to decide on slavery through popular sovereignty. The second proposal involved the strengthening of the Fugitive Slave Law, which mandated that escaped slaves be returned to their owners, thereby appeasing Southern interests while attempting to maintain a fragile balance between free and slave states.
The Mexican Cession, which followed the Mexican-American War, intensified debates over slavery in the newly acquired territories, exacerbating regional tensions between the North and South. This led to the emergence of the Compromise of 1850, which aimed to address the status of slavery in these areas but ultimately failed to provide a lasting solution. Additionally, the cession raised questions about the expansion of U.S. territory and the treatment of Native American populations, contributing to ongoing conflicts and political strife in the region. These issues played a significant role in the lead-up to the Civil War.
