# bmnreth > bmnreth is a public market desk for NYSE:BMNR (BitMine Immersion Technologies) and its Ethereum treasury: ETH NAV, mNAV, discount to NAV, BMNR/ETH, listed BMNR options, and last US regular-session option trades. bmnreth marks disclosed ETH holdings with a live spot price and subtracts SEC balance-sheet liabilities. It is an estimate, not BitMine’s official NAV and not investment advice. The homepage and this file are public. The options chain and signed-in overview require a free account.

Negative means the share trades under NAV - BMNR price: Hyperliquid HIP-3 BMNR market - ETH spot: Hyperliquid - BMNR/ETH candle: HIP-3 BMNR USD price divided by ETH spot for the same hour, from 2026-09-05 00:00 UTC - BMNR options, quotes, Greeks, and implied volatility: Tiger OpenAPI - Session trades: option prints in the US regular window 09:30–16:15 America/New_York. Premium = price × contracts × multiplier (100 unless the contract says otherwise) - Open interest: official print, snapshotted at 18:00 America/New_York. During 09:30–16:00 ET the change is current open interest minus the latest snapshot. Outside that session, after today’s snapshot exists, the change is the latest snapshot minus the previous trading day’s snapshot - IV rank = (current − window low) / (window high − window low) × 100. BMNR uses 30-day option IV. ETH uses Deribit DVOL - IV percentile = share of samples in the window strictly below the current reading - Clocks named in ET use America/New_York, so the same wall time follows EST in winter and EDT in summer ## Contact - Site: https://bmnreth.com/ - Support: support@bmnreth.com - X: https://x.com/bmnreth_com
