Kalshi Nears $12 Billion in All-Time Notional Trading Volume

While no single source directly states that Kalshi's all-time notional trading volume is exactly '$12 billion,' the most relevant and authoritative evidence strongly supports the plausibility of this claim. A key piece of evidence is a high-authority source stating that Kalshi is 'on track for $50 billion in trading volume' by October 2025. For the company to be on such a trajectory, achieving an all-time volume approaching $12 billion at an earlier date is a logical and consistent milestone. This narrative of massive growth is further corroborated by a direct statement from Kalshi's CEO, Tarek Mansour, who confirmed that trading volume on the platform had increased by more than 100x. The other sources provided are largely irrelevant, as they either focus on specific, small-scale markets or are too dated to reflect the company's recent exponential growth. Crucially, there is no conflicting evidence that suggests a different or lower figure for the all-time volume. The combination of a high future projection and confirmed massive growth from authoritative sources makes the statement highly probable.
