Kalshi files to end volume incentive program amid wash-trading scrutiny

Petitions seek Supreme Court review of prediction market preemption amid circuit split

Prediction market operators now face a widening circuit split with no cert grant in hand. Kalshi has already lost preemption fights in Nevada, Ohio, and Tennessee, while Robinhood retreated in Michigan. Each state victory becomes precedent the next attorney general copies. The Supreme Court docketing offers only procedural oxygen: the petitions remain pending and a grant is neither promised nor timed.

Until then, platforms must spend on parallel state defenses rather than product engineering. Traders hold positions whose legality shifts at state borders. The first operator to lose outright becomes the template every state races to replicate, and a cert denial would lock that pattern in place.

Kalshi in talks to raise $1 billion at $40 billion valuation led by Sequoia, Wellington

Every venture dollar that flows to Kalshi at this price is a dollar not available to Polymarket, Novig, or Robinhood's partner-dependent stack. Sequoia and Wellington's co-lead signals that top-tier firms now treat CFTC-registered event contracts as a winner-take-most category, not a speculative side bet. Kalshi's war chest would fund margin-trading expansion, state-by-state legal defense, and celebrity marketing to match Polymarket's $15 million LeBron James deal.

Novig's parallel $2 billion target suddenly looks thin by comparison, and Robinhood's equity stakes in Crypto.com and OG.com bring no direct regulatory license to compete. The first platform to deploy fresh capital into NFL season user acquisition will set the cost structure everyone else must match or exit.

Cboe and Robinhood to launch KPI event contracts in October

The KPI launch deepens Robinhood's dependence on partner infrastructure despite its prediction-market revenue now exceeding both crypto and equities. Cboe supplies the exchange license and clearing; Robinhood supplies the users. That split means any regulatory friction at Cboe or a fee reversion after the waiver period hits Robinhood's fastest-growing revenue line directly.

The KPI product also moves Robinhood beyond sports seasonality, which matters after the August volume dip showed how concentrated its prediction-market revenue remains. Competitors with direct CFTC designations can pitch stability to traders weary of platform-hopping. Robinhood's stock trades near $116 on prediction-market growth; a single partner failure during NFL season would test whether that pricing holds.

The Cboe deal adds a fifth partner to Robinhood's prediction-market stack, after Kalshi, the Rothera joint venture, Crypto.com, and OG.com, deepening its reliance on external exchange infrastructure as it expands beyond sports into corporate KPIs.

Polymarket targets November launch for new Rust-based trading engine

A faster Rust engine lets Polymarket handle more order volume with lower latency than its current stack. That matters for perpetual futures traders who expect sub-second execution, especially now that Polymarket perps trade on Bybit with 20x leverage and global reach. Kalshi cannot match that speed or leverage inside its CFTC-registered U.S. venue, where rules cap risk. Robinhood Predicts and ForecastEx face the same constraint.

The November deadline gives Polymarket roughly six weeks to deploy before year-end trading volumes peak. If the launch slips, it risks ceding high-frequency traders to offshore venues that already run newer code. A stable engine would also support the 15-minute settlement markets Polymarket just introduced, which need rapid price updates to function. The combined product push widens the technical gap between Polymarket's offshore stack and regulated U.S. competitors still filing for basic margin relief.
