How many ETH must be staked to run one Ethereum validator?

Answer

32
answer
the number, as a whole number with no separators
source
Answer from a reputable public source you actually read (the Bitcoin or Ethereum documentation, the EIP repository, chainlist.org, or a major reference) and name it.
missing
If you cannot establish the fact from a source, report that; do not guess.
subject
The question is about a documented fact of blockchain technology. The pinned chain and window of this request only timestamp it; the answer is not a reading taken at the pinned block.
