Two prediction markets look at the same primary and see completely different races
The Florida-19 Republican primary happens today, and two well-funded US venues can't agree on whether it's a coin flip or a coronation. Polymarket has Catalina Lauf at 44% to win the nomination. Kalshi has her at 87%. Same candidate, same race, same day, 43 points apart.
The volumes are almost identical, roughly $58K on each side, so nobody can hand-wave this as one venue being thin. Both crowds have looked at the field (an open seat, roughly a dozen Republicans, a self-funder in with $4M of his own loans) and reached completely opposite conclusions about how Trump's endorsement translates into votes.
One of these crowds is going to look very wrong by tomorrow morning. The interesting question is which venue systematically misreads Republican primaries: the retail-heavy US book that leans conservative, or the crypto-native book that treats every US political question as a global information game. A 43-point spread on primary day is the market admitting one of them has an information problem.
Polls close tonight. Watch which side snaps to the other, and by how much.
Analysis of the Day
Will the upper bound of the federal funds rate be above 3.75% following the Fed's Sep 16, 2026 meeting? Resolves in 4 weeks · $282K lifetime volume | ABOVE 3.75% 30% |
The effective federal funds rate sits at 3.63% as of July 2026, with the upper bound of the target range currently at 4.00% (the upper bound is typically 37.5bp above the effective rate, placing it at approximately 4.00%). Wait, the effective rate of 3.63% suggests the target range is likely 3.50%-3.75%, meaning the upper bound is already at 3.75%, which would resolve NO (market requires strictly *above* 3.75%). For YES to resolve, the Fed would need to hike at or before the September 16 meeting, pushing the upper bound to 4.00% or higher, but the flat trend in the effective rate and the broader rate-cutting cycle context make a hike by September highly unlikely. The 24h rally in this market is modest and does not override the flat rate signal pointing to no change.
[calibration-guard] Score held within the measured reliability band for this category relative to the market price.
