Bitcoin Week 18, 2026: ETF AUM Hits $100B, Treasury Yields Top 5%, and Strategy Surpasses IBIT

What Happened This Week in Bitcoin (Week 18, 2026)

Bitcoin opened Week 18 at $78,126 with five major developments pulling institutional sentiment in competing directions. The 30-year US Treasury yield crossed 5% on April 30, its highest level since July 2025. MARA Holdings announced a $1.5 billion acquisition of a 505MW Ohio gas plant for an AI and HPC campus, the largest infrastructure pivot by a Bitcoin miner in 2026. Strategy surpassed BlackRock's IBIT to become the single largest Bitcoin holder on earth. Bitcoin ETF AUM crossed $100 billion for the first time since November 2025. And the April 28-29 FOMC held rates but produced the most divided vote in 33 years, as Jerome Powell held his final press conference as Fed Chair.

1. 30-Year Treasury Yield Crosses 5%: A New Capital Allocation Headwind for Bitcoin

Key data: 30-year yield at 5.0% (highest since July 2025) | 10-year at 4.42% | Bitcoin fell from $79,000 to $75,612

On April 30, the yield on the 30-year US Treasury note crossed 5%, a level tested only twice in the past two decades. Three forces converged to push the long end higher during the week.

First, the FOMC's 8-4 dissent vote on April 29, in which four officials pushed back on any easing bias. ING analysts described the dissenters as sending a warning shot aimed at incoming Fed Chair Warsh, signaling that those officials would not be easily moved toward rate cuts. Second, oil re-accelerated toward $126 per barrel on April 23-24 after reports that President Trump was being briefed on military options to extend the Iran blockade, and after the US seized three Iranian tankers. Third, long-term inflation expectations rose as breakeven inflation rates embedded in TIPS climbed, with markets pricing a longer energy shock than the two-week ceasefire had suggested.

Why it matters for Bitcoin: A 30-year Treasury at 5% is a near risk-free alternative return for every dollar considering a non-yielding digital asset. The 30-year real yield reached 2.71% on April 30. Bitcoin has no yield, no dividend, and no contractual cash flow. Every basis point of real yield expansion raises the hurdle rate for Bitcoin's expected return proportionally.

sFOX Chief Business Officer Diana Pires framed the dynamic directly: rising yields and tight Fed policy give capital a real alternative to risk assets, continuing to pressure crypto.

Bitcoin declined from its $79,000 weekly high to close April 30 at $75,612, a 4.3% pullback that tracked almost exactly with the yield move. Gold also fell more than 1% to a one-month low.

The resolution event: April CPI on May 12 determines whether this yield pressure extends or reverses. A print at or below 3.5% would pull the 30-year back from 5% and remove the primary macro headwind. A print above 4.0% extends yield pressure and delays Bitcoin's recovery.

2. MARA Holdings Acquires Long Ridge Energy for $1.5 Billion: Bitcoin Miners Are Now AI Infrastructure Companies

Key data: $1.5B total transaction value | 505MW combined-cycle gas plant | 1,600 acres | $144M annualized EBITDA | AI buildout target: mid-2028

On April 30, MARA Holdings announced a definitive agreement to acquire Long Ridge Energy & Power LLC from FTAI Infrastructure. The acquisition includes a 505 megawatt combined-cycle natural gas power plant in Hannibal, Ohio and over 1,600 contiguous acres of land already equipped with power, water, and fiber access.

Deal highlights:

• Total capacity increases MARA's owned and operated power by approximately 65% to roughly 2.2 gigawatts across PJM, ERCOT, SPP, and international markets
• Long Ridge contributes approximately $144 million in annualized adjusted EBITDA at all-in operating costs below $15 per megawatt-hour
• Initial AI and HPC buildout is targeted to begin in first half 2027, with capacity ready for service in mid-2028
• Assumed debt of $785 million, backstopped by a Barclays bridge loan
• MARA's co-located Hannibal data center has already received inbound interest from multiple investment-grade AI and hyperscaler tenants

MARA CEO Fred Thiel's framing at the Bitcoin 2026 Conference in Las Vegas was unambiguous: power is the scarce input in AI.

The structural significance: The Long Ridge acquisition is the clearest single signal that the Bitcoin mining industry has completed its identity shift. Companies that spent 2020-2025 building energy infrastructure and compute hardware for Bitcoin proof-of-work are now the most naturally positioned entities in the US to service AI's demand for cheap, reliable power in large contiguous blocks.

This deal also reframes MARA's March Bitcoin sale. MARA sold 15,133 BTC ($1.1 billion) in March to retire convertible debt. Long Ridge reframes that as capital allocation: MARA monetized Bitcoin at $73,000-$74,000 to acquire $144 million in annual EBITDA from an energy platform with AI infrastructure optionality. The EBITDA alone pays back the non-debt portion of the acquisition in under five years at current energy prices.

3. Strategy Surpasses IBIT as the World's Largest Bitcoin Holder: 818,334 BTC

Key data: Strategy holds 818,334 BTC | IBIT holds ~802,823 BTC | Average cost basis: $75,537 | Bitcoin Yield YTD: 9.6%

Strategy disclosed on April 27 that it had purchased 3,273 BTC for approximately $255 million during the week ending April 26, at an average price of $77,906 per coin, funded through the sale of 1.45 million Class A shares via the MSTR ATM program. Total holdings reached 818,334 BTC, surpassing BlackRock's IBIT to make Strategy the single largest Bitcoin holder on earth.

Strategy's reserves now represent over 60% of all Bitcoin held by publicly traded companies globally and 3.9% of Bitcoin's 21 million hard cap. The April 27 purchase followed a 34,164 BTC acquisition for $2.54 billion the prior week, making April Strategy's most aggressive accumulation month in 2026 with combined purchases of approximately 51,364 BTC for roughly $3.8 billion.

Why this milestone matters beyond the leaderboard: Strategy surpassing IBIT describes a fundamental difference in supply structure. IBIT is a pass-through vehicle: its 802,823 BTC represent institutional investors who can redeem at any time, with the underlying BTC sold to meet redemptions. IBIT's holdings are only as permanent as its investors' conviction. Strategy's 818,334 BTC are unconditionally held on a corporate balance sheet with no redemption mechanism, structurally removed from tradeable supply in a way ETF shares are not.

Michael Saylor's comment on the latest purchase: "The beat goes on."

4. Bitcoin ETF AUM Crosses $100 Billion for the First Time Since November 2025

Key data: $823.7M net inflows (week ending April 24) | Total AUM: $102.64B | Four consecutive positive weeks | Combined four-week inflows: ~$2.9B

The week ending April 24 delivered the fourth consecutive week of positive Bitcoin ETF flows, with $823.7 million in net inflows according to SoSoValue data. Cumulative total net inflows reached $58.56 billion. The $100 billion AUM level had served as the institutional allocator threshold since it was first crossed in 2024; recovering it confirms the institutional selling cycle that began in November 2025 has completed.

Four-week inflow breakdown:

• Week ending April 10: $786.3M
• Week ending April 17: $996.4M
• Week ending April 24: $823.7M

Ethereum ETFs extended their own positive streak to three consecutive weeks at $155 million, with cumulative net inflows above $12.1 billion and total AUM at $13.79 billion. SOL ETFs recorded $9.44 million and XRP ETFs $15.74 million. MSBT, Morgan Stanley's fund, continued building momentum after a strong debut.

The macro tension: The ETF inflow data describes a market where institutional capital is simultaneously adding Bitcoin exposure and being offered a competitive risk-free alternative in 5% 30-year Treasuries. That tension resolves based on whether April CPI confirms the energy shock is unwinding. If yields retreat from 5%, the ETF inflow tailwind and the yield headwind both move in Bitcoin's favor simultaneously.

5. FOMC April 2026: Most Divided Fed Vote Since 1992, Powell's Final Press Conference

Key data: Rate held at 3.5-3.75% | 8-4 dissent vote | Most divided since October 1992 | Fed Funds futures: ~90% odds of at least one cut by year-end

The April 28-29 FOMC delivered the expected outcome, rates held unchanged at 3.5-3.75%, but in a form nobody had forecast: an 8-4 dissent vote, the most divided Federal Open Market Committee since October 1992. The dissent was bidirectional: some of the four dissenting officials wanted to raise rates in response to elevated headline inflation; others wanted to cut, citing slowing growth signals and arguing that March CPI's energy-driven headline overstated underlying inflationary pressure.

This was Jerome Powell's final press conference as Fed Chair, with his term ending May 15 when Kevin Warsh is expected to take over. Powell confirmed he would remain on the Board of Governors until an investigation into the Federal Reserve's renovations is resolved.

ING analysts noted that the hawkish dissenters' timing appeared intentional, using the final meeting before a new chair arrives to signal they would not be easily swayed toward rate cuts under Warsh.

Goldman Sachs economist David Mericle had forecast one dissent. Four arrived.

Why the 8-4 split is structurally bullish on a medium-term view: Four officials dissenting in two different directions means the committee has no consensus view and will respond to data rather than ideology. If May CPI confirms the energy shock is normalizing, the dissenting doves become the majority view and rate-cut probability for June or July rises sharply.

The Warsh variable: Warsh is characterized as more market-signal-responsive than Powell on policy timing. A Warsh-led Fed that receives a constructive May CPI has both the flexibility and the institutional mandate to signal the first rate cut since 2025, removing the last macro headwind the 2026 bear market installed.

Bitcoin May 2026 Outlook: Three Catalysts to Watch

Catalyst 1: April CPI (May 12)

The first inflation print to begin capturing the ceasefire's oil price relief. March CPI at 3.3% was the peak of the Iran war energy passthrough.

• Bull case: Print at or below 3.5% YoY confirms the disinflationary path, gives Warsh's Fed cover to signal a rate cut, and pulls the 30-year yield back from 5%
• Bear case: Print above 4.0% (Oxford Economics flagged uncomfortably strong April data as a risk) extends yield pressure and delays the recovery's next leg

Catalyst 2: Kevin Warsh Fed Transition (mid-May)

Warsh's first policy communications will establish whether his market-signal-responsive reputation translates into dovish flexibility or hawkish orthodoxy. Early Warsh language acknowledging the energy shock's transitory nature would represent the most bullish Fed signal since December 2023.

Catalyst 3: CLARITY Act Senate Markup

Targeted for late April, now likely slipping to May. A Senate Banking Committee advancement would put the bill on a floor vote timeline before the midterm political deadline. Polymarket's 72% odds and JPMorgan's projection of a positive catalyst both assume a May-June vote. A confirmed floor date would be the regulatory equivalent of the 2024 ETF approval announcement.

Week 18 Summary: What It All Means

Week 18 closed Q2's first month with Bitcoin's institutional recovery confirmed across every structural metric: $100B ETF AUM recovered, Strategy at record holdings surpassing IBIT, and net 2026 flows positive. Simultaneously, a new macro headwind arrived in the form of a 30-year Treasury at 5%, the highest since July 2025.

MARA's $1.5 billion Long Ridge acquisition formalized the structural identity shift the Bitcoin mining industry has been building toward since 2023: Bitcoin miners are now energy and AI infrastructure companies, and the infrastructure built for proof-of-work is being repositioned for the most capital-intensive compute cycle in modern history.

May 12 CPI is the resolution event for every tension this week introduced.
