More than 150 Polymarket wallets may have traded on military secrets, research finds - @reuters.com www.reuters.com/business/fin...
Nonprofit ACDC identifies 556 "Orca" Polymarket wallets that frequently appear, trade and disappear

ACDC identifies 152 of those Orca wallets that bet on military markets with 97.2% average win rate

ACDC finds that some of those bets drew copycat wagers before Iran military action

Trading, however, is concentrated in a few high-profile races. This means the majority of markets are still extremely thin and small - low volumes of trading, and few wallets. Small bets move the price in most markets.
A scatter plot showing the prediction market volume and number of wallets trading in each market on the US 2026 midterm elections. 77% of markets are concentrated in the 'thin and small' quadrant.

The number of markets opened on congressional elections has exploded. There are already 16 times as many as there were in 2024. This means more granular, niche questions on outcomes like primaries, margins, turnout, speeches and endorsements.
A bar chart showing the number of prediction markets on midterm congressional eleections opened per quarter from 2024 to 2026. In Q1 2026, the number of markets increases suddenly, from hundreds, to around 2000 markets opened per quarter. Two pie charts showing the subject of congressional midterm election markets on major prediction market platforms in 2024 v 2026. 
In 2024, 71% of markets were about the winner of the race. 
In 2026, that is just 14%, with primary results now and margin / vote share now accounting for 76% together.

🗳️ On Kalshi, Polymarket and Polymarket US, tens of milions of dollars are being bet on the US congressional midterm elections in November. 💵 Three months before election day, betting volume has already exceeded the 2024 cycle. But, just 1% of users control 68% of the volume on Polymarket. 🧵
A chart comparing cumulative total prediction market trading volume on the 2026 and 2024 midterm elections. 
2026 shows a total of $133.3m through August 10. 2024 shows a total of $92.4m in the weeks after Election Day.

But political markets were different. They were the second most successful category for longshot bets, with 25% of such bets winning. We observed $35 million in winning-outcome longshot wagers. $9 million of that was bet in 10 weeks in 2026!

We identify around $8 billion in trading volume in the political markets most susceptible to information advantage: those determined and knowable in advance by a group of insiders. These are frequently the biggest category of political markets on Polymarket.

For years, the US has led the pack on the investigation and enforcement of foreign bribery. Wednesday’s memo by AG Pam Bondi shifting DoJ focus away from cases that aren’t linked to drug cartels puts that in jeopardy. 📊 From @anticorruption.bsky.social's 2022 Exporting Corruption report.
