Prediction market platform Kalshi has announced a series of measures to prevent insider trading, including a requirement that some users disclose their employment details. The New York-based firm said the move is designed to screen out users with non-public knowledge on markets deemed to be at heightened risk of manipulation.

Coverage Comparison

Reporting on the story varied in focus. Al Jazeera centered its coverage on Kalshi's new measures and the company's broader efforts to address market manipulation, while The Guardian — World emphasized the federal investigation into former Congressman George Santos and his alleged betting activities on Kalshi.

Key Claims

Kalshi announced it has started collecting job information for markets it considers to be at heightened risk of manipulation, as reported by Al Jazeera. The company's "market integrity measures" also include a scoring system to determine the risk levels of different markets and a dedicated 24/7 channel for receiving whistleblower reports, according to the same source.

Both Al Jazeera and The Guardian reported that Kalshi sanctioned three US political candidates for betting on their own campaigns. Additionally, both outlets reported that George Santos is under investigation for insider trading in connection with a bet he allegedly placed on his own attendance at the State of the Union address.

According to The Guardian — World, Kalshi flagged the trade to the Commodity Futures Trading Commission. The Guardian also reported that Santos was sentenced to seven years in prison after pleading guilty to wire fraud and identity theft, and that his sentence was later commuted by Trump.

Perspectives

Kalshi: The company framed its actions as a proactive effort to lead the industry on market integrity, citing the findings of its Independent Surveillance Audit Committee and implementing measures to prevent insider trading.

George Santos: The former congressman declined to confirm or deny having a Kalshi account, responding to reports by saying he does not engage with what he called "rag reporting."

What was claimed, and who backed it

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
