The nonprofit Anti-Corruption Data Collective (ACDC) suggested on Thursday that insider trading on military information may be happening on the prediction market. ACDC’s study identified “long-shot” bets, defined as wagers of at least $2,500 placed within an hour on an outcome with odds of 35% or less. ACDC identified 556 wallets, known as “Orcas,” that showed a pattern of opening an account, placing a successful long-shot bet, and then often cashing out and disappearing. Among these, 152 wallets, which made collective earnings of $8 million with a win rate of 97.2%, were particularly successful in military and defense markets. ACDC co-founder **David Szakonyi** cautioned that unusual betting activity on Polymarket is highly observable and often copied by big traders and bots. “It would be naive to think foreign-intelligence agencies aren’t monitoring these markets,” he said. *Polymarket and the Department of Defense did not immediately respond to Benzinga’s request for comments*. **Read Also: JPMorgan Debanked Polymarket Over Regulatory Concerns, But Eyes Role in Potential IPO: Report** ## Prediction Markets Under Regulatory Fire Earlier this month, a Haaretz investigation highlighted that a Polymarket trader known as **25xp** allegedly made $200,000 by correctly predicting the U.S.-Iran ceasefire and placed about $40,000 on **Benjamin Netanyahu** remaining prime minister after Israel’s Oct. 27 election. The report suggested the bets may be intended to influence market odds rather than simply profit from them. The account previously made only the ceasefire bet, while another account, **OnlyBibi2026**, has also made substantial pro-Netanyahu wagers. Meanwhile, last month, a Stanford University and Singapore Management University study raised concerns about alleged manipulation of Polymarket’s five-minute **Bitcoin** (CRYPTO: BTC) binary contracts. Researchers found that traders may buy Bitcoin on Binance during the final seconds of a contract to push the settlement price above the opening price, increasing their chances of receiving the $1 payout. Furthermore, the Commodity Futures Trading Commission (CFTC) reportedly launched an investigation into the “mention markets” on prediction market platforms, leading Kalshi to suspend all mention markets in its sports betting segments. The scrutiny of prediction markets follows a White House disclosure last month that a teleprompter operator allegedly bet on President **Donald Trump**’s speeches and lost his job, raising concerns about insider trading and market manipulation. ***Disclaimer*:** *This content was partially produced with the help of AI tools and was reviewed and published by Benzinga editors*. **Read Also: BTC Cracks $68,000 and You May Want to Look at Kalshi to Predict Bitcoin's Next Move Before Binance Does** *Image via Shutterstock* ### Related Stocks - [GBTC.US](https://longbridge.com/en/quote/GBTC.US.md) - [FBTC.US](https://longbridge.com/en/quote/FBTC.US.md) - [BITB.US](https://longbridge.com/en/quote/BITB.US.md) - [ARKB.US](https://longbridge.com/en/quote/ARKB.US.md) - [IBIT.US](https://longbridge.com/en/quote/IBIT.US.md) - [BITO.US](https://longbridge.com/en/quote/BITO.US.md) - [BRRR.US](https://longbridge.com/en/quote/BRRR.US.md) - [BTCO.US](https://longbridge.com/en/quote/BTCO.US.md) - [BTCW.US](https://longbridge.com/en/quote/BTCW.US.md) - [HODL.US](https://longbridge.com/en/quote/HODL.US.md) - [EZBC.US](https://longbridge.com/en/quote/EZBC.US.md) - [03008.HK](https://longbridge.com/en/quote/03008.HK.md) - [03042.HK](https://longbridge.com/en/quote/03042.HK.md) - [03430.HK](https://longbridge.com/en/quote/03430.HK.md) - [BTCE.DE](https://longbridge.com/en/quote/BTCE.DE.md) - [JPM.US](https://longbridge.com/en/quote/JPM.US.md) - [SSTK.US](https://longbridge.com/en/quote/SSTK.US.md) - [JPM-M.US](https://longbridge.com/en/quote/JPM-M.US.md) - [JPM-C.US](https://longbridge.com/en/quote/JPM-C.US.md) - [JPM-D.US](https://longbridge.com/en/quote/JPM-D.US.md) - [JPM-L.US](https://longbridge.com/en/quote/JPM-L.US.md) - [8634.JP](https://longbridge.com/en/quote/8634.JP.md) - [JPM-K.US](https://longbridge.com/en/quote/JPM-K.US.md) - [JPM-J.US](https://longbridge.com/en/quote/JPM-J.US.md) ## Related News & Research - [Metaplanet Buys 1,007 More Bitcoin As Treasury Hits 20,000 BTC](https://longbridge.com/en/news/297936992.md) - [ProCap Financial sells 50 Bitcoin to repurchase shares at 40% discount](https://longbridge.com/en/news/297963677.md) - [Hilbert Group shifts strategy to monetization, targets revenue growth after integration phase](https://longbridge.com/en/news/297739875.md) - [GoMining Launches Instant Funds for Digital Bitcoin Miner Holders](https://longbridge.com/en/news/297160037.md) - [Capital B Raises €21 Million to Accelerate Bitcoin Treasury Strategy](https://longbridge.com/en/news/297279683.md) --- > **Disclaimer: This article is for reference only and does not constitute any investment advice.**
