- Internally, the AI assistant is referred to as Harrison.
- Harrison guarantees event contract wording is thoroughly vetted for loopholes.
- The AI also compiles news and evaluates competing contracts.
Kalshi is leveraging artificial intelligence (AI) to facilitate swift resolutions of event contracts and reduce disputes during a critical growth period for the operator.
Recent media reports suggest that the largest prediction market firm in the U.S. is employing Anthropic’s Claude AI, internally named Harrison. A core function of Harrison is to rigorously examine and tweak event contracts prior to their public release. While Kalshi traders may not engage with Harrison directly, they are likely to experience the positive effects of its work.
Harrison’s extensive role involves scrutinizing event contracts pre-launch to reduce or abolish wording ambiguities that could lead to resolution disputes and dissatisfaction among users.
A crucial aspect of Harrison’s responsibilities is aggregating news, as many event contracts are linked to economic, political, pop culture, and weather events, in addition to monitoring the offerings from competitors.
Harrison: A Potential Trust-Building Entity for Kalshi
Though the prediction market sector is in its infancy, it has already faced several controversies related to ambiguous contract wording.
A notorious incident occurred with a 2025 Polymarket contract questioning whether Ukrainian President Volodymyr Zelensky would don a suit before July. He did wear one at a NATO meeting, but bettors on the “no” side contested it wasn’t a formal suit.
In January, a Kalshi market regarding mentions of Warner Bros. during a Netflix (NASDAQ: NFLX) conference concluded with a “no” outcome because a Netflix executive referred to “Warner Brothers,” not its shorthand. Numerous instances like these demonstrate how contract language has confused traders who believed they were winning.
By integrating AI to oversee contract resolutions, Kalshi can lessen the subjective influences of human judgments while fostering enhanced trust among bettors and traders. For instance, Claude AI confirms Zelensky’s suit-wearing at the NATO event while recognizing its significance.
The Role of Harrison
Although Harrison does not interact with traders directly, its effectiveness could significantly impact Kalshi as trading volumes grow. In May alone, Kalshi managed a notional volume of around $18 billion, with $5.1 billion processed in the initial days of the World Cup.
With over 5 million usage scenarios, the company achieved a valuation of $22 billion following a $1 billion funding round in March.
