The combined 12 U.S. spot Bitcoin exchange-traded funds have surpassed the 1.1 million BTC +1.60% estimated to be held by the cryptocurrency’s pseudonymous creator Satoshi Nakamoto for the first time.

"KING OF THE HILL: The U.S. spot ETFs have just passed Satoshi in total bitcoin held, now hold more than 1.1 million, more than anyone in the world, and they're not even a year old yet, literally babies still. Mind blowing," Bloomberg ETF analyst Eric Balchunas posted on X.

According to data from CoinGlass, the combined U.S. spot Bitcoin ETFs now hold 1,105,923 BTC. BlackRock’s IBIT product leads the pack with 521,164 BTC having recently surpassed half a million bitcoin, followed by Grayscale’s converted GBTC fund with 214,217 BTC and Fidelity's FBTC with 199,183 BTC.

The Bitcoin ETFs reached the milestone following a positive flow streak that has seen the funds net over $33 billion in total inflows since trading began in January, with nearly $2.4 billion added this week week alone. Thursday's $766.7 million worth of net inflows (approximately 7,800 BTC) tipped the funds over the 1.1 million BTC mark, according to data compiled by The Block.

  Alongside bitcoin’s 130% price surge to above the $100,000 level this year, the ETFs now have more than $100 billion in assets under management.

While Satoshi, as an individual or a group, is likely the largest bitcoin holder, other known entities also have substantial holdings.

MicroStrategy’s 402,100 BTC (worth over $40 billion) makes it the largest corporate holder, having adopted bitcoin as its primary treasury reserve asset since 2020, with plans to raise $42 billion in capital over the next few years for further bitcoin acquisitions. The United States' 208,109 BTC ($21 billion) in seized funds places it as the largest nation-state holder, ahead of China and the United Kingdom, according to Bitcoin Treasuries.

Satoshi’s billions

Satoshi Nakamoto's estimated holdings of approximately 1.1 million BTC are based on a detailed analysis of early bitcoin mining patterns conducted by researchers such as Sergio Demian Lerner, who identified a specific "Patoshi Pattern" in the blockchain.

Lerner observed a distinct mining pattern in the early Bitcoin blocks, believed to belong to Satoshi, which consistently avoided mining consecutive blocks to maintain network decentralization.

Satoshi is thought to have mined around 22,000 of the first blocks, which, when multiplied by the 50 BTC block subsidy reward at the time, yields the 1.1 million BTC figure. These coins have remained unspent since their creation, further supporting the belief that they belong to the pseudonymous creator.
