Material from Earth.

The leading explanation is the giant-impact hypothesis: a Mars-sized body (Theia) hit the early Earth and ejected mostly Earth’s mantle material (with some material from the impactor) into orbit, which accreted into the Moon. Isotopic similarities between Earth and Moon rocks (especially oxygen isotopes) and the Moon’s small iron core support this.
