Dark matter has negative mass.

the verdict
CONTESTED PARTIAL
Recorded sources
5 sources for · 3 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that dark matter has negative mass?

Partly. Several speculative theoretical papers propose that dark matter could consist of negative-mass matter, but they explicitly describe this as an unproven hypothesis or toy model. A critical peer-reviewed review finds the negative-mass cosmology has serious observational problems, and reference works note negative matter is forbidden in general relativity.
