Kalshi raised $1 billion at a $22 billion valuation, according to a Bizjournals listing of New York City venture capital activity. The item appeared alongside news that David Protein's parent company raised $250 million for food brands. No further details on the Kalshi round were provided in the listing.

A $1 billion raise at $22 billion would dramatically expand Kalshi's war chest for product expansion and regulatory battles, reshaping capital benchmarks for the regulated prediction-market sector.
