Messari analyst says only KYC-based prediction markets can realistically curb insider trading
Messari research analyst Austin Weiler argues that insider trading can only be meaningfully deterred on prediction markets that implement Know Your Customer checks, while fully onchain, non-KYC platforms face near-impossible enforcement. He notes that even KYC cannot completely prevent abuse, as insiders may still pass information to third parties, but it allows platforms to restrict access and raise enforcement standards amid growing scrutiny of political and geopolitical betting.

Trump says Venezuela leak source jailed as traders linked to Polymarket bets go inactive
On Wednesday in the Oval Office, US President Donald Trump said that the person responsible for leaking information on Venezuela "has been found and is in jail," following a series of well-timed Polymarket wagers on President Maduro's potential removal. Blockchain researchers have since noted that two of three wallets tied to profitable Venezuela bets have gone inactive, while a third wallet recently shifted focus to prediction markets concerning Iran's leadership. The situation has intensified US policy discussions over insider trading risks on political prediction platforms.

Polymarket wallet behind $400K Maduro ouster bet vanishes after USDC payout on Polygon
A Polymarket account identified as "0x31a56e" that made roughly $400,000 from a wager on former Venezuelan President Nicolás Maduro's capture and removal is now inaccessible on the platform. The account had placed about $32,000 on Maduro's ouster and related U.S.-Venezuela conflict markets, and later moved more than $436,000 in USDC from its Polygon address on Jan. 3. Its disappearance, while other user pages remain visible, is intensifying scrutiny over potential insider trading and transparency issues on prediction markets.
