Bitcoin ETFs made headlines in the week to 12 May 2025 as they took nearly all the money entering crypto investment products. According to a weekly fund flows report by digital asset manager CoinShares, Bitcoin products attracted $867 million of the $882 million in net inflows into crypto funds. The surge reflected a growing appetite among institutional investors for regulated, Bitcoin-backed financial products.

Bitcoin News: Why Are Institutions Flocking to Bitcoin?

James Butterfill, Head of Research at CoinShares, attributed the inflows to a combination of global economic factors. These included a noticeable rise in the M2 money supply, a measure of liquid assets available for spending or investing, and growing stagflation concerns in the US economy. He also pointed out that several US states had recently approved Bitcoin as a strategic reserve asset, which boosted its credibility in mainstream finance.

The M2 Money Supply Factor

The M2 money supply includes savings accounts, money market funds and small time deposits. Economists and policymakers watch this figure closely to understand consumer spending potential. Since the second half of 2023, M2 had been rising again, suggesting that more capital was circulating, some of it flowing into digital assets via ETFs.

Record-Breaking Cumulative ETF Flows

US-listed Bitcoin ETFs set a new milestone at the time. Since their launch in January 2024, these funds had accumulated $62.9 billion in net inflows, above the previous record of $61.6 billion set a few months earlier. The data underscored how ETFs were becoming the preferred gateway for institutional exposure to crypto.

Ethereum and Sui See Mixed Responses

While Bitcoin products saw strong demand, not all digital assets shared the spotlight. Ethereum, despite a surge in market activity, attracted only $1.5 million in fund inflows. Sui, in contrast, pulled in $11.7 million and even outpaced Solana, which recorded $3.4 million in net outflows.

The US Securities and Exchange Commission (SEC) appeared more open to crypto ETFs than in years past but faced a heavy backlog: more than 70 crypto ETF proposals were pending, and the last major approval had come in July 2024 with the Ethereum ETFs.

What Changed Since May 2025

• The ETF backlog cleared: in September 2025 the SEC approved generic listing standards that let exchanges list spot crypto ETFs without a lengthy case-by-case review. The first US spot Solana ETFs started trading on 28 October 2025, followed by the first spot XRP ETF on 13 November 2025.
• State reserves: after New Hampshire and Arizona in May 2025, Texas also passed a law for a state Bitcoin reserve in June 2025. The debate at federal level is covered in our article on the Bitcoin state reserve bill H.R. 8957.
• Price: Bitcoin closed at about $102,800 on 12 May 2025, rose to a record near $126,200 on 6 October 2025 and fell to about $57,800 on 1 July 2026, based on Binance daily data. On 25 September 2026, CoinGecko listed it at about $84,700.
• ETF flows in 2026: US spot Bitcoin ETFs saw net outflows for long stretches of 2026. Strong inflows from mid-August onwards brought them back to a positive balance for the year in September 2026, according to daily flow data compiled by Farside Investors.

Bitcoin News: Final Thoughts

The May 2025 flows showed a clear institutional shift toward regulated crypto products, and that shift continued: the ETF shelf is far broader today than it was then. What the flows did not do was protect the price. Institutional demand makes Bitcoin easier to access, but it does not turn it into a calm asset.
