Welcome to another edition of The Bitcoin Weekly!
Every week, we break down the four most important events shaping Bitcoin, from protocol updates to the macroeconomic and geopolitical forces driving the market. We explain what happened, why it matters, and how it impacts your stack. Plus, we always include one educational concept to help you level up your Bitcoin knowledge.
Let’s dive into this week’s top stories.
1. U.S. Airstrikes Send Bitcoin Tumbling Below $73K
The geopolitical situation in the Middle East flared up again this week. U.S. Central Command carried out airstrikes on an Iranian military site near the Strait of Hormuz and shot down four attack drones. The strikes reversed recent ceasefire optimism, sending global stocks lower and oil prices higher. Bitcoin, which had been holding steady above $74,000, broke support and dropped below $73,000 for the first time since mid-April
The drop triggered a massive leverage flush. Nearly $1 billion in leveraged crypto positions were wiped out in 24 hours, with long positions making up 93% of the liquidations. This shows how quickly the market can punish traders who get over-leveraged on the assumption of a straight line up. While Bitcoin is a long-term safe haven, in the short term, it still trades as a highly liquid risk asset that reacts violently to sudden geopolitical shocks.
2. BlackRock's IBIT Sees Near-Record $528M Outflow
On Wednesday, BlackRock's iShares Bitcoin Trust (IBIT) saw $527.84 million in net outflows, its second-largest single-day withdrawal since launching in January, missing the all-time record by just $500,000. Across all 11 U.S. spot Bitcoin ETFs, total outflows reached $733.43 million for the day. This extends a multi-session streak that has pulled more than $2 billion from the ETFs over the past two weeks
The ETF outflows and the price drop fed each other as investors redeemed shares amid the Iran news, BlackRock and others were forced to sell the underlying Bitcoin. Interestingly, this followed a massive $1.29 billion "dark pool" block trade in IBIT the day prior. It suggests that institutional investors are tactically trimming their Bitcoin exposure to de-risk amid the macro uncertainty. The question now is whether this is a temporary pullback or a deeper institutional shift.
3. The CLARITY Act Heads to the Senate Floor
Following its successful 15-9 bipartisan passage through the Senate Banking Committee last week, the Digital Asset Market Clarity Act (CLARITY) is now officially heading toward a full Senate floor vote. The crypto industry is heavily mobilizing to secure the necessary votes. The bill would grant the CFTC exclusive jurisdiction over spot markets for decentralized digital commodities like Bitcoin
The momentum behind the CLARITY Act is one of the most bullish structural developments for Bitcoin in U.S. history. If passed, it permanently removes the threat of SEC overreach and establishes Bitcoin definitively as a digital commodity. This regulatory certainty is the final missing piece required for massive, conservative pools of capital (like pension funds and sovereign wealth funds) to allocate to Bitcoin.
4. Bitcoin's On-Chain Demand Has Gone Quiet
A detailed analysis published this week by Swissblock revealed that U.S. spot Bitcoin ETFs have absorbed a net total of just 4,500 BTC since the start of 2026, an unusually thin number given that these same products were the structural buyer that powered the entire 2025 rally. May has fully flipped from accumulation to distribution, pushing Swissblock's Risk Index into "high-risk" territory. Separately, CryptoQuant reported this week that whale and dolphin accumulation has stalled, with on-chain demand at its weakest level since December 2025.
This is the most important structural signal of the week and arguably the most honest read on where the market actually stands. The 2025 Bitcoin rally was primarily driven by ETF inflows - institutional buyers absorbing supply faster than miners could produce it. That engine has stalled. With ETF demand near zero year-to-date, whale accumulation paused, and geopolitical risk spiking, the market is in a demand vacuum. The good news: demand vacuums are historically temporary. The bad news: they can last longer than traders expect.
5: Bitcoin Concept of the Week: The "Dark Pool"
In the story about BlackRock's ETF outflows, we mentioned a $1.29 billion "Dark Pool" block trade. What exactly is a dark pool?
When you buy or sell Bitcoin on a regular exchange (like Coinbase or Kraken), your order goes onto a public "order book." Everyone can see it. If you try to sell $1 billion worth of Bitcoin on a public exchange, the market will see that massive sell wall, panic, and the price will crash before your order even finishes filling. This is called "slippage."
A Dark Pool is a private financial forum or exchange for trading securities (or crypto) where the order book is not visible to the public. Institutional whales use dark pools to execute massive block trades directly with other large buyers/sellers at an agreed-upon price.
Because the trade happens "in the dark," it doesn't immediately crash the public market price. It allows institutions to move massive amounts of capital without tipping their hand to retail traders. When you see dark pool activity spiking, it's a sign that the "smart money" is quietly repositioning.
