Grayscale Executive "Bitcoin ETF, $15 Billion Inflow Possible This Year"

▲ Bitcoin Spot ETF

Bitcoin (BTC) spot ETFs have grown into a $100 billion asset class within two years of their launch. Amidst this, a Grayscale executive raised the possibility of $15 billion in inflows this year, reigniting the battle for Bitcoin on Wall Street.

According to the economic media outlet TheStreet on May 26 (local time), Krista Lynch, Senior Vice President of ETF Capital Markets at Grayscale, projected that approximately $15 billion could flow into Bitcoin spot ETFs this year. Lynch stated, "It's a very exciting time with several tailwinds, and I believe it's entirely possible that approximately $15 billion will flow into Bitcoin ETFs this year alone."

TheStreet reported that U.S. Bitcoin spot ETFs have become the asset class with the largest initial capital inflows in ETF history within two years of their launch, with total assets under management exceeding $100 billion. BlackRock's IBIT has emerged as the company's single largest revenue generator, and approximately 75% of its first million investors were new investors, not existing BlackRock clients. IBIT reached $70 billion in assets under management in 341 trading days, five times faster than SPDR Gold (GLD) and Vanguard S&P 500 ETF (VOO) reached the same size.

Bitcoin spot ETFs attracted an additional $47.2 billion in 2025. This was only 3% lower than the first year of launch, a different trend from the sharp slowdown in funds typically seen in ETFs in their second year. Currently, the total assets under management for Bitcoin spot ETFs are approximately $102 billion, and U.S. Bitcoin spot ETFs are reported to hold about 6.77% of the total Bitcoin supply. IBIT's assets under management were reported to be approximately $62 billion as of the end of May 2026.

Lynch used the recent quarterly inflow of approximately $3 billion as the basis for this year's forecast. He stated, "Looking at all Bitcoin products, approximately $3 billion flowed in this quarter. If you simply annualize that, total inflows could be around $12 billion." Lynch explained that adding the additional demand that the in-kind creation and redemption structure will unlock makes a $15 billion forecast possible. TheStreet reported that the total net inflow into Bitcoin spot ETFs in Q1 this year was approximately $1.5 billion, and in May, $1.55 billion flowed out over one week due to six consecutive days of outflows, but April saw $2.44 billion in inflows, showing the strongest monthly trend this year.

The key change is in-kind creation and redemption. The SEC approved in-kind creation and redemption for Bitcoin and Ethereum (ETH) spot ETFs in July 2025. Under the previous cash-based method, to move Bitcoin into an ETF, one first had to sell it, convert it to cash, and then buy ETF shares, which triggered a taxable event. Lynch explained that with long-term Bitcoin holders now able to directly deposit Bitcoin into a fund and receive ETF shares, access to the U.S. financial system for estate planning, margin, and collateral use has increased. He said, "There's a certain type of crypto-native investor who holds tokens and wants access to the U.S. financial system. This means putting them into accounts that can be used for estate planning, margin, and collateral."

Grayscale is maintaining its remaining investor base despite the high fee burden of GBTC, while also targeting new demand with its low-cost product, the Grayscale Bitcoin Mini Trust. GBTC was launched as a trust in 2013, converted to an ETF in January 2024, and has an annual fee of 1.5%. IBIT and FBTC fees are both 0.25%, and most competing products are in the 0.15% to 0.25% range. GBTC has seen cumulative net outflows of approximately $25.9 billion since its conversion, but still holds over $11 billion in assets under management. Lynch stated, "GBTC has a very sticky investor base," and "it's possible that BTC products will take a larger share of that."
