Here are some of the top contenders:\n\n---\n\n## Biggest Heists by Value\n\n1. **LuBian Cryptocurrency Hack (2020)**  \n   This is likely the *single largest heist ever*. A mining pool called *LuBian* lost **127,426 Bitcoins** in a 2020 breach, worth **$3.5 billion at the time**, and about **$14.5 billion today** when rediscovered by Arkham Intelligence five years later. ([tomshardware.com](https://www.tomshardware.com/tech-industry/cryptocurrency/usd3-5-billion-bitcoin-hack-from-2020-dwarfs-mt-gox-in-value-is-worth-usd14-5-billion-today-intelligence-firm-uncovers-heist-that-shuttered-6th-largest-bitcoin-mining-pool?utm_source=openai))\n\n2. **Central Bank of Iraq (2003)**  \n   Often considered one of the biggest physical bank heists: on March 18, 2003, roughly **$920 million** was taken from the Central Bank of Iraq in Baghdad\u2014orders allegedly from Saddam Hussein. In real terms (2016 USD), that\u2019s about **$1.3 billion**. ([worldatlas.com](https://www.worldatlas.com/articles/biggest-robberies-in-world-history.html?utm_source=openai))\n\n---\n\n## Other Notable Heists\n\n- **Antwerp Diamond Heist (2003, Belgium):** More than **$100 million** in diamonds, gold, and jewelry were stolen. Dubbed the \u201cheist of the century\u201d in the diamond world. ([en.wikipedia.org](https://en.wikipedia.org/wiki/Antwerp_diamond_heist?utm_source=openai))\n\n- **Dresden Green Vault Burglary (2019, Germany):** Royal jewelry, including famous diamonds; estimated at around **$132 million**, though initial reports were much higher. Some items have been partially recovered. ([thetravel.com](https://www.thetravel.com/historys-biggest-museum-heists/?utm_source=openai))\n\n- **Bybit Crypto Heist (2025):** Hackers stole about **$1.5 billion in Ethereum** from the exchange\u2019s wallets. ([visualcapitalist.com](https://www.visualcapitalist.com/sp/ranked-the-10-biggest-digital-heists-in01/?utm_source=openai))\n\n---\n\n### Final Take\n\nIf you're looking at **value in dollars**, the LuBian Bitcoin theft is currently considered the biggest heist in history, especially when you take its later valuation into account. If you're thinking more along the lines of **physical robbery** (cash, art, jewelry), the Central Bank of Iraq is one of the most significant.\n\nIf you tell me whether you're more interested in **cash heists**, **crypto thefts**, or **art/precious items**, I can narrow it down even more."
