Kalshi Kills Incentive Program After Wash Trading Claims
Platform hits $52.98B monthly volume record even as it shuts the reward scheme under scrutiny.
Kalshi is shutting down its liquidity incentive program after wash trading allegations surfaced against the prediction market platform, even as its monthly trading volume hit an all-time high of $52.98 billion in September 2026, according to The Block.
Why It Matters
Prediction markets have faced persistent questions about the legitimacy of their reported volumes, and wash trading — artificially inflating figures by trading with oneself — strikes at the credibility of the entire sector. Kalshi's decision to end the program suggests internal acknowledgment that incentive structures may have distorted activity metrics, even if the company stops short of admitting wrongdoing. For retail participants, inflated volume figures can create a misleading picture of market liquidity and price discovery quality. Regulators watching the CFTC-regulated platform will likely treat this episode as a test case for how prediction markets self-police incentive design.
Context
Kalshi operates as a regulated prediction market under CFTC oversight, distinguishing it from offshore competitors, and has positioned that regulatory status as a trust signal to institutional and retail traders alike. As of September 2026, its $52.98 billion monthly volume figure — reported by The Block with the caveat that September data remains incomplete as of September 29 — represents a record for the platform. Liquidity incentive programs are common in crypto and prediction market venues to bootstrap order books but frequently attract participants whose primary motive is harvesting rewards rather than genuine price speculation.
What's Next
Kalshi has not publicly detailed what, if any, replacement mechanism it will use to maintain order book depth after the program ends. The wash trading allegations may also draw scrutiny from the CFTC, making the coming weeks critical for the platform's regulatory standing.
