Bitcoin ETFs on Track to Hold 10% of Total Supply by Mid-2029

The Bitcoin and Ethereum spot ETFs in the US have attracted $68.4 billion in committed capital across two product lines, launched just three years ago. This sum represents a significant portion of the market's total assets under management.

As of September 18, these funds held $102.532 billion in assets, accounting for 6.29% of Bitcoin's total market capitalization. To reach the next milestone of 10%, they would need to accumulate an additional $60.5 billion, which is expected to take around three years.

The accumulation rate averages approximately $1.71 billion per month, but it's essential to note that historical data shows fluctuating inflows and outflows in response to market changes. The current pace assumes a consistent flow of capital into these funds.

When 10% of Bitcoin is held by ETFs, the impact on market dynamics will be significant. One key effect is the reduction in floating supply, which means fewer coins are available for trading and circulation. This can lead to more volatile price movements as demand rises or falls.
