MARA Holdings reported in its latest 10-K that it began selling Bitcoin in the second half of 2025 and plans to continue monetizing BTC in 2026 to improve financial flexibility. The miner holds a treasury of 53,822 BTC, part of which is used for passive income, and may sell additional coins depending on market conditions and capital priorities.

A large trader identified as 0x007 has opened a 20X leveraged short position on tokenized silver on Hyperliquid’s HIP-3 platform, with a notional value above $12.34M and unrealized gains that recently fluctuated around $2M. The position, which benefits from positive funding fees and has a liquidation level at $107.96 while silver trades near $83.67, highlights how some crypto participants are using silver as a comparatively safer and more liquid shorting instrument than altcoins. Silver remains among the top traded commodities on HIP-3 even after losing its top spot to gold, as traders return to short strategies now that the metal has moved into a perceived safer range.

Core Scientific plans to liquidate around 2,500 BTC from its treasury, with most of the sales expected in the first quarter of 2026, to fund capital expenditures for AI data centers. The miner, which reported a 57% drop in BTC production and lower revenue in Q4 2025, will also sell current block rewards and does not intend to rebuild its Bitcoin reserve.

Strategy expanded its bitcoin treasury by 3,015 BTC, financed through a weekly capital raise combining $7.1M from STRC preferred stock and $229.9M from MSTR common shares. The firm paid about $204.1M at roughly $67,700 per BTC, bringing total holdings to 720,737 BTC at an average purchase price of $75,985.

In February 2026, Railgun's total value locked climbed above $113M, with most deposits concentrated on Ethereum and smaller amounts on Polygon, Arbitrum, and BNB Chain. The privacy mixer is widely used to obscure WETH and stablecoin flows in DeFi, even as the RAIL token slipped to around $1 with a monthly decline exceeding 46%. Railgun now captures a dominant share of the mixing market, but recent exploits show its screening approach has limits.

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. In February, prediction markets handled about $21B in volume, with Polymarket at $7.34B, both lower than January levels of over $26B and $7.6B.

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. One case involved a California gubernatorial candidate; the other named a Mr. Beast video editor. The platform also recorded $8.5B in February trading volume, approaching January’s $9.5B peak.
