Bitcoin ETF inflows reach $999 million in largest day of 2026

U.S.-listed spot Bitcoin ETFs recorded $998.95 million in net inflows on Monday, the largest daily total of 2026, according to SoSoValue data cited by CoinDesk. For investors tracking bitcoin ETF inflows 2026, the figure shows a strong single-day reading, while the group still remained in net-outflow territory for the year.

CoinDesk reported that the funds were down about $450 million year to date after Monday's activity. Cointelegraph put the year-to-date deficit at about $464 million, a difference in rounded reporting that does not change the broader point: one large day had not erased earlier net outflows.

Which Bitcoin ETFs led the nearly $999 million inflow?

BlackRock's iShares Bitcoin Trust, known as IBIT, brought in $381.37 million, according to Farside Investors data cited by CoinDesk. Ark's ARKB added $289.12 million, and Fidelity's FBTC received $238.84 million.

• BlackRock IBIT: $381.37 million
• Ark ARKB: $289.12 million
• Fidelity FBTC: $238.84 million

Those three funds accounted for a combined $909.33 million, or about 91% of the reported $998.95 million total. The concentration illustrates that the day's reported flows were largely centered in those products, rather than being evenly distributed across the market.

How does Monday's Bitcoin ETF inflow rank?

The total exceeded the previous 2026 daily high of $844 million, set on Jan. 14, according to SoSoValue figures reported by Cointelegraph. It was also the biggest daily intake since Oct. 6, 2025, when spot Bitcoin ETFs drew more than $1.2 billion.

CoinDesk ranked Monday as the ninth-largest daily inflow since the U.S. spot Bitcoin products began trading in January 2024. The Securities and Exchange Commission approved the listing and trading of several spot bitcoin exchange-traded products that month, while stressing that its action did not endorse bitcoin. The SEC's approval statement also said the decision was limited to products holding bitcoin.

What do daily Bitcoin ETF flows reveal about buyers?

They do not identify who ultimately put money into the funds. A separate analysis from the Bitcoin Foundation noted that daily flow data cannot establish whether purchases came from institutions, advisers, retirement accounts or individual brokerage customers. As a result, the nearly $1 billion figure is evidence of reported net fund flows for that day, not proof that a particular type of investor drove them.

Bitcoin traded around $85,430 when Cointelegraph published its report, after briefly moving above $87,200 on Monday, according to CoinGecko data cited by the publication. The price move and ETF flows occurred on the same day, but the available reports do not establish that either caused the other.
