A cluster of Polymarket wallets has made confident company‑earnings bets focused on firms audited by KPMG. Analysts observed concentration across 155 prediction pairs and wagers placed shortly before public disclosures.

On February 27, 2026, up to eight major wallets on Polymarket's ZachXBT prediction market were flagged for unusually large gains after backing Axiom. The market drew over $39M in volume, with 3,630 wallets participating and early odds near 15% enabling outsized profits; one leading wallet bridged USDC to Ethereum.

Vitalik Buterin has nearly finished selling a planned portion of his ETH, with on-chain data indicating 16,420 ETH sold primarily for Ethereum Foundation funding and charitable causes. The sales, mostly around $2,000 per ETH and slightly above the initially discussed 16,384 ETH, come as the Foundation holds about 172K ETH and presents its Strawman roadmap for faster L1, higher throughput and future upgrades.

On February 25, 2026, Kalshi said it closed two insider trading cases and reported them to the CFTC, issuing multi‑year bans and financial penalties.

On February 24, 2026, Meteora emerged as the leading candidate on Polymarket to be named in ZachXBT's upcoming insider trading investigation scheduled for February 26. Traders pushed Meteora's implied odds as high as 53%, while MET fell over 15% to around $0.18 amid short positions and growing speculation.

Jane Street significantly raised its IBIT and MSTR shareholdings in Q4 and February 2026, including a 53.78% jump to 20.3M IBIT shares valued at $1B.

On February 23, 2026, Solana-based AI agent Lobstar drew attention after sending $441K worth of its meme token in response to a social media request for a 4 SOL donation. The recipient sold the entire amount into a pool with $300K liquidity, realizing about $40K due to slippage and briefly crashing the token price. Lobstar later recovered, with its liquidity climbing to $455K, while observers debated whether the event was a genuine mistake or a publicity tactic.

On February 19, 2026, a Federal Reserve Finance and Economics Discussion Series paper reported that Kalshi’s prediction markets can match the accuracy of professional economic forecasters, especially for federal funds rate expectations. The study compared Kalshi’s market-implied forecasts to survey-based and other market-based methods, highlighting Kalshi’s continuously updated risk distributions. It also noted that Kalshi operates with full CFTC regulatory approval, unlike Polymarket, which remains in a legal gray area despite comparable liquidity in some markets.
