4-bullet brief | narrative

0% price means the market assigns effectively zero probability to Lula finishing third or worse in the first round.
24h volume of $12K equals 25% of all-time, marking a notable one-day attention spike on a contract already near-resolved.
Volume at zero likely reflects traders closing short positions or arbitrageurs clearing residual liquidity as the outcome is treated as settled.
Resolves on official Brazilian electoral first-round results; Lula is a dominant frontrunner in all current polling.
