TL;DR: BlackRock’s IBIT recorded roughly $665 million in net inflows on October 19, even as several other US spot Bitcoin ETFs saw investors take money out.

A strong day for Bitcoin ETFs wasn’t quite as broad-based as the headline number suggests. BlackRock’s iShares Bitcoin Trust took in approximately $665.16 million on Monday, according to SoSoValue’s fund-flow figures, while the US spot Bitcoin ETF group recorded a combined inflow of about $526.6 million.

That difference is the story. Money going into IBIT more than offset withdrawals from competing funds. Fidelity’s FBTC registered roughly $83.6 million in outflows, while Grayscale’s GBTC shed about $54.9 million.

Rather than a uniform surge of demand for every Bitcoin product, Monday’s numbers point to a preference for the market’s biggest vehicle. IBIT has become the default choice for many investors seeking exchange-traded Bitcoin exposure, although a single day’s figures cannot establish why individual institutions moved money.

The reversal also follows a Friday session in which the group recorded net withdrawals. It underscores how quickly flows can shift around market volatility and broader risk sentiment.

Flows are useful evidence of ETF subscriptions and redemptions, but they shouldn’t be read as a direct measure of new cash buying Bitcoin at a particular hour. Fund mechanics and market-making activity complicate that picture.

The next question is whether demand spreads to other products or whether IBIT continues to absorb most of the market’s incremental interest.

BlackRock Files for Bitcoin ETF With Downside Buffer and Capped Upside

BlackRock has filed for a new bitcoin exchange-traded fund which, if approved, would cap investors’ upside while limiting their losses. 

The iShares Bitcoin Managed Protection ETF, or PBIT, would aim “to create and manage bitcoin exposure,” according to a Monday filing with the Securities and Exchange Commission. 

It would work buying options and fixed-income strategies to give investors regulated bitcoin exposure with capped upside and some downside protection — but not direct bitcoin ownership. 

The fund would suit investors who want to invest in bitcoin but not experience all the volatility that comes with the top cryptocurrency. 

Bitcoin has attracted attention for its wild price swings over the years but its volatility has dampened as more investors have bought into the space. 

But 2025 was the least volatile year for the asset and the bear market of 2026 has been its most shallow on record: in past cycles, bitcoin’s price has dropped as low as 80% from its all-time high; this year it shed just 50% of its value. 

BlackRock’s iShares Bitcoin Trust — IBIT — started trading in 2024 after the SEC gave the green light to 11 spot bitcoin ETFs. 

The most successful of the ETFs in terms of flows, the investment vehicle has helped bring bitcoin to Wall Street. Now traders, institutions and retail investors can quickly buy shares that track the price of the leading cryptocurrency. 

They don’t need to worry about exchanges or storage of the digital coin, rather, BlackRock buys and holds the bitcoin while investors simply hit the buy or sell button via their brokerage account. 

IBIT has the most assets under management out of the bitcoin ETFs, currently handling $65.7 billion. 

On Monday, the fund received $665.2 million in fresh investment as bitcoin buyers flooded back into the market. 

That’s the biggest number of shares bought in the product since October 2025, when bitcoin notched a new all-time high, according to Farside Investors data.

TL;DR: BlackRock has proposed another Bitcoin-linked ETF, this time using options to pursue some protection against losses while giving up part of the potential upside.

BlackRock’s latest Bitcoin fund filing takes a different approach from the familiar buy-and-hold exposure offered by its iShares Bitcoin Trust. Instead of simply following the price of Bitcoin, the proposed iShares Bitcoin Managed Protection ETF would use an options strategy linked to IBIT or similar exposure.

The ambition is straightforward enough: participate in some of Bitcoin’s gains and seek a measure of protection during a decline. The trade-off is equally important. Gains could be capped, and the protection is neither unconditional nor guaranteed. The structure is designed around overlapping options positions, meaning an investor’s outcome could depend on when the shares are purchased as well as what Bitcoin does next.

That makes this a different kind of product, not a safer version of holding spot Bitcoin in every circumstance. Options costs, fund expenses and changing market prices all affect what shareholders receive.

The filing arrives as issuers work to move beyond basic spot exposure. Income-oriented and buffered Bitcoin products try to give financial advisers additional ways to fit an unusually volatile asset into conventional portfolios.

For investors, the missing details matter as much as the proposed strategy. An SEC filing does not mean the fund has been approved or launched. Its eventual fees, live portfolio and actual protection terms will determine whether the structure delivers a useful alternative to IBIT.

TL;DR

• Roughly $15.6 billion of Bitcoin options expired on Deribit on September 25.
• Bitcoin traded around $83,600 after the settlement, below the week’s near-$87,000 high but still well above its earlier trading range.
• XRP and Solana continued outperforming Bitcoin over the week even as the large derivatives expiry passed.

One of the largest Bitcoin options expiries of the year has passed without blowing up the spot market.

Approximately $15.6 billion in BTC options reached settlement on September 25, clearing a huge concentration of derivatives positions while Bitcoin held in the mid-$83,000 range.

The Expiry Removed A Large Block Of Hedging Exposure

Ahead of settlement, the options book represented roughly 182,000 BTC.

Calls substantially outnumbered puts, with about 106,200 BTC of call open interest against roughly 75,900 BTC of puts in the expiry.

Those positions settled through Deribit’s regular expiry process.

Large quarterly expiries matter because options dealers and traders often hedge their exposures in the spot and futures markets.

As expiry approaches, changes in price can force those hedges to be adjusted.

Once the contracts settle, some of those flows disappear.

That does not mean a $15.6 billion expiry translates into $15.6 billion of Bitcoin being bought or sold.

The figure represents the notional value of the options contracts.

Still, removing that much open interest can change short-term market positioning.

Bitcoin Cooled While Some Large Altcoins Kept Running

Bitcoin traded around $83,600 after pulling back from an intraday high near $87,000 earlier in the week.

The move left BTC below its recent peak but still above the range that contained it before the latest breakout.

At the same time, several large altcoins continued to outperform.

XRP was up roughly 15% across seven days, while Solana had gained around 9%.

That divergence suggests the expiry was not producing a broad flight from crypto risk.

Instead, capital was still moving around inside the market even as Bitcoin paused.

Options expiries are often surrounded by dramatic predictions about “max pain” levels or prices being forced toward particular strikes.

The actual market is less deterministic.

Dealer hedging can influence short-term trading, but spot demand, macro conditions, ETF flows and broader positioning continue to matter.

The important development is simply that a very large derivatives event is now behind the market.

With the September quarterly book cleared, Bitcoin’s next move should depend less on traders managing that expiry and more on whether buyers are willing to keep supporting the rally without it.

TL;DR

• US spot Bitcoin ETFs recorded $998.96 million in net inflows for the September 21 session.
• BlackRock IBIT led with $381.4 million, followed by ARKB at $289.1 million and FBTC at $238.8 million.
• The figure is a single-day flow total, not cumulative ETF inflows.

US spot Bitcoin ETFs came within a rounding error of a billion-dollar inflow day on September 21.

The group recorded $998.96 million in net inflows, the largest single-session total of 2026 in the validated data set.

Three Funds Drove Most Of The Demand

BlackRock’s IBIT led the session with $381.4 million.

ARK 21Shares’ ARKB followed with $289.1 million, while Fidelity’s FBTC added another $238.8 million.

Together, those three products accounted for the overwhelming majority of the day’s net buying.

For Bitcoin traders, that matters because ETF flows are one of the cleaner windows into regulated US spot demand.

The products have become a meaningful source of marginal buying and selling pressure, particularly on days when flows are large enough to stand out from the surrounding market.

One Huge Day Still Needs Follow-Through

Nearly $1 billion in a single session is significant, but it should not be confused with a cumulative-flow milestone.

It also does not guarantee that the same pace will continue.

ETF demand can reverse quickly depending on price, macro conditions and institutional positioning.

Even with that caveat, September 21 gives the market a hard number that is difficult to dismiss.

Almost $1 billion of net capital entered US spot Bitcoin ETFs in one trading day, with the biggest issuers all contributing meaningfully.

The next few sessions will show whether that was an isolated allocation surge or the start of a more sustained run of institutional demand.
