What is a halving?
Every 210,000 blocks (about every four years) the reward miners get for a new block is cut in half. New bitcoin supply slows down, while the maximum supply stays capped at 21 million. Past halvings were followed by large price moves, but each cycle was different and nothing is guaranteed.
