The assessment is based on strong, direct evidence from a highly authoritative primary source. The Bloomberg article (Source 1), with the highest relevance score, explicitly states that Kalshi is "fielding investor offers at a valuation between $10 billion to $12 billion or higher," citing its own reporting based on inside sources. This claim is directly supported and repeated by other reputable, albeit secondary, sources like The Block (Sources 6 and 9), which credit Bloomberg for the information. Several other sources report on Kalshi's past, completed funding rounds, which resulted in lower valuations of $2 billion and $5 billion (Sources 2, 3, 4, 5). While these sources seem contradictory at first glance, they are reporting on historical facts. A company having a previous valuation of $2 billion does not contradict a report that it is currently *seeking* a new, higher valuation of $12 billion. These are separate events in the company's financial timeline. Therefore, these sources provide context but do not invalidate the primary claim about Kalshi's current fundraising ambitions.The claim is highly likely to be true as it originates from a top-tier financial news organization and is being reported by others in the industry. The only reason for a slight degree of uncertainty (preventing a 1.0 probability) is that the information comes from unnamed "people familiar with the matter" rather than an official public announcement from Kalshi itself.
