Polymarket’s Ethiopia & Romania markets rack up $600m post-result

Polymarket blocked the accounts involved but has not explained why they traded so much first, WIRED reports.

The hit

Two Polymarket election markets drew over $600m in trading volume largely after the races were already decided, according to WIRED. Most trading was on long-shot losers in Ethiopia & Romania, with researcher Chris Park tracing $284m of the Ethiopia total to pairs of accounts trading with each other.

Why it matters

For bettors, it undercuts the pitch that prediction markets reflect real public belief. If huge volume can come from accounts trading with themselves rather than genuine wagers, headline figures & odds on Polymarket become far less trustworthy as a guide to what traders actually think will happen.

What happens next
