Kalshi KXBRPRES — Brazil Presidency Data

A series-day bundle contains every Brazil Presidency contract that was listed on Kalshi on that UTC day — traded or not — 2 contract files on the latest covered day.

Event contracts quote 0..1; turnover is USD-normalized.

Prices quote 0..1 (probability of Yes). Open/high/low/close/VWAP are that UTC day’s trade prints per contract; the implied outcome reads the last print — ≥ 0.97 as Yes, ≤ 0.03 as No, anything between as still open — venues publish the official result. Buy share = taker-buy side of turnover; spread = the contract's turnover-weighted quoted bid-ask spread in cents, top-1 depth = mean best-bid/ask notional per side, L2 updates = order-book level updates recorded for the contract that day. “Settles” is the venue-listed close time of the contract where the venue publishes one (UTC).

On Kalshi, a Brazil Presidency contract trades for about 259 days from open to close, is listed roughly 231 days before it opens, and quotes in 0.1 ¢ price steps (0..1). Measured on the 2 contracts captured on 2026-10-26.

Split by election cycle and by race, never at random — months of quotes on one contract are one regime, and a random split leaks the result backwards; validate across races and cycles, not within one. The election-markets guide works thin books, book updates as the main signal and calibration over months through.
