Kalshi PreStocks (KALSHI) on Solana

Spotify removed more than 500,000 artificially generated streams from indie-pop artist Malcolm Todd's track "Earrings" after the song's suspicious rise from No. 4 to No. 1 on the platform's daily U.S. chart attracted scrutiny. The surge — a roughly 70% jump in U.S. streams over a single day — was linked to prediction market activity on Kalshi, where traders had placed bets on which song would top the chart. Kalshi traders flagged the anomalous streaming behavior on social media, and Spotify confirmed that the streams appeared to originate from bots and would not generate royalties.

Kalshi, which had already distributed payouts to traders who bet on the June chart winner, said it is investigating the incident in coordination with Spotify. The episode highlights an emerging risk for platforms that track discrete, gameable metrics: when financial stakes attach to specific outcomes like chart rankings, bad actors gain an incentive to manipulate the underlying data. Spotify also requested that Kalshi and rival platform Polymarket remove its branding and make clear that no partnership exists between them.

Kalshi CEO Tarek Mansour pushed back on criticism that prediction markets enable insider trading, arguing the opposite is true compared to traditional stock markets. In stock markets, Mansour explained, the link between private information and a trade is obscured by the many factors influencing a stock price — an insider who knows about an upcoming product launch buys a company's stock, but that connection is buried in noise. In prediction markets, the signal is direct: a trader with foreknowledge of a specific outcome bets on that outcome, making the information-to-trade relationship transparent and far easier to flag.

The comments come amid scrutiny following a federal investigation into former Rep. George Santos, who made trades on Kalshi around the State of the Union address in February. Mansour noted that Kalshi has implemented employment verification requirements, whistleblower mechanisms, and rapid investigation protocols as safeguards against abuse. The regulatory environment remains unsettled, however: Minnesota Governor Tim Walz signed a statewide ban on prediction market contracts in May 2026, and several other states are weighing similar restrictions.

Traders on Kalshi's prediction market are pricing in a softer-than-expected June nonfarm payrolls print, putting less than 60% odds on job growth surpassing 100,000 and only about 42% odds on clearing 125,000. That's well below the Dow Jones consensus of 118,000 and a sharp step down from May's 172,000 — which itself more than doubled Wall Street's prior estimate. On unemployment, Kalshi traders are more aligned with consensus: a 71% chance the rate comes in above 4.2%, but only a 30% probability it exceeds the current 4.3%.

The data illustrates Kalshi's growing footprint as a real-time economic barometer. By aggregating crowd-sourced bets on macro outcomes, the platform surfaces a market-implied probability distribution for labor data that differs meaningfully from sell-side point estimates — and which, in the case of May's payrolls, proved closer to the outcome. The Bureau of Labor Statistics releases the June jobs report Thursday.

Kalshi announced a strategic partnership with ADI Predictstreet on June 26, 2026, to expand its prediction market presence during and beyond the 2026 World Cup. Under the deal, Kalshi branding will appear in stadiums, on broadcasts, and in digital advertising alongside ADI Predictstreet, while Kalshi assists in growing available markets throughout the tournament. ADI Predictstreet, which launched just three days before the World Cup kicked off on June 11, operates in partnership with sports streaming platform DAZN and Fanatics Markets for U.S. market access, using its ADI Chain technology to deliver live markets and event tracking.

The partnership follows a strong opening week for Kalshi at the tournament: the platform processed $5.1 billion in trades during the first week of World Cup competition, including a single-day record of $1.7 billion on one Wednesday. The deal broadens Kalshi's physical and digital footprint at the world's most-watched sporting event, pairing it with an official tournament prediction market partner that already has broadcast and streaming distribution locked in.
