Kalshi metronome bot stops after $2M wash trading pattern

A trading bot that executed a $1 trade on Kalshi’s Zohran Mamdani contract every two seconds has stopped. Prediction market analyst TickerTracker tracked the activity for nearly two months, noting the uniform rhythm of the back-and-forth orders. The halt followed allegations that such activity inflated the exchange's trading volume without genuine market interest. TickerTracker characterized the automated sequence as a metronome, highlighting the precise regularity of the orders that drew immediate attention from the prediction market community.

TickerTracker described the bot's behavior as a metronome, buying shares for two-tenths of a cent and "selling them for one-tenth of a cent" every four seconds. This pattern generated $2 million in notional volume between August 1 and September 19. The bot’s cessation has not resolved the broader dispute over Kalshi's data integrity, which expanded to its ether perpetual contracts last weekend. The uniformity of the transactions, which persisted for almost two months, remains a central point of contention among analysts scrutinizing the platform's liquidity metrics.

Pseudonymous quant analyst "Beni" claimed Kalshi's 24-hour ether perpetual volume was $539 million while open interest was only $3.1 million. They flagged that $5,500 trades made up 58% of that volume over four days. Kalshi’s crypto lead, IcoBeast.eth, initially rebuffed the claims but later acknowledged the personal attacks were "cocky and unnecessary." In a formal response, the exchange stated that "wash trading rumors are false." This defensive posture contrasts with the statistical anomalies that continued to surface in the daily trading data.

Analysis from Pluang confirms the scrutiny, noting that nearly half of the ether perpetual volume clustered around a single trade size. This concentration raises questions about the authenticity of the reported activity. New York Attorney General Letitia James's office has separately determined that Kalshi's prediction market is an illegal, unlicensed gambling operation, a finding that adds regulatory pressure to the data integrity concerns. The Federal Reserve's next rate decision is scheduled for October 28, 2026, and the next CPI release is set for October 14, 2026, according to the Bureau of Labor Statistics, providing key economic anchors for future market assessment.
