PitchBook values Kalshi at $30.4B with $42B Supreme Court upside
PitchBook published an initiation report on September 24, 2026, valuing Kalshi at $30.4 billion. The base case rests on expected 2028 adjusted earnings. A $42 billion upside scenario depends on a favorable Supreme Court ruling in a sports betting case. The report's title frames Kalshi as a prediction market for anything except its own future. Kalshi awaits judicial resolution of regulatory disputes over sports event contracts.
Kalshi's valuation is now legally levered: the $42 billion case requires the Supreme Court to reverse the Ninth Circuit's tribal-lands reasoning. The same circuit has rejected Kalshi's preemption theory twice in recent days, in Nevada and California. Each loss invites more tribal suits and forces additional geofences. Robinhood, which routes volume through Kalshi and holds stakes in partner platforms, shares this exposure.
Traders hold positions whose validity shifts with geography. If the Supreme Court declines certiorari or rules against federal preemption, the $30.4 billion base case itself becomes vulnerable. Legal spend compounds across parallel cases faster than any single resolution. The first quarter of 2027 will test whether Kalshi can book earnings before courts book more losses.
