Strategy added 34,164 BTC last week at ~$74,395 per coin — a $2.54 billion deployment that puts Michael Saylor's firm above BlackRock's IBIT on BTC held for the first time. Total position: 815,061 BTC at a $75,527 average cost basis, $61.56 billion deployed. IBIT sits at 802,823 BTC as of the latest flow prints. The week's buy is Strategy's largest since November 2024 and its third-largest all-time.
The funding came from a $366 million MSTR at-the-market equity program paired with $2.18 billion of STRC preferred issuance — the same capital-stack mechanics Strategy has used all cycle, scaled up. Saylor's "think even bigger" weekend post on X telegraphed the move two days before the 8-K. The number that arrived is the concrete version of that post.
815,061
Total BTC held by Strategy as of the April 20 filing. For the first time, the largest non-self-custody Bitcoin holder on the planet is a public-company treasury, not an ETF. IBIT trails at 802,823. The symbolic flip has been telegraphed for months — this is the week it happened.
The MSTR equity reaction is the counter-signal. Despite the third-largest weekly buy in the company's history and the BlackRock milestone, MSTR stock barely moved on the news — TipRanks and Bitcoin Magazine both flagged the flat reaction. That's a different market from the one that rallied 15% on every Saylor filing in 2021. The bid for "Bitcoin treasury company" exposure is still there, but the mNAV premium compression is real, and it's starting to get priced into the headlines.
$75K already resolved. $80K sits at 31% against a BTC spot of ~$75,657 — implied volatility over the final 9 days of April is the real signal. Strategy accumulating at $74,395 prints a floor the market is already converging on.
Full-year upside tiers. $100K at 35% is meaningfully below consensus equity research year-end targets. The Strategy 1M-coin target requires an implicit price floor well above here.
♦ Absence flag
No direct Polymarket market exists for "Will Strategy hold more BTC than BlackRock IBIT at any month end?" or "Will MSTR outperform BTC over 2026?" — both would be obvious hedging instruments for the mNAV compression thesis. The absence is the signal: capital has no clean way to short the mNAV premium directly via Polymarket today.
The Accumulation Arc — How Strategy Passed BlackRock
April 6–12, 2026
Strategy purchases 13,927 BTC for ~$1 billion at an average $71,902 per coin, funded via STRC preferred stock. The first tranche of what becomes a 48,000-coin April sprint.
April 18 (weekend)
Saylor posts "think even bigger" on X. Observers correctly read it as a pre-filing signal. Over the same weekend, US-Iran tensions escalate and the Hormuz ceasefire deadline becomes public.
April 20, 2026 (SEC filing)
Strategy discloses a 34,164 BTC purchase the prior week at ~$74,395 avg — $2.54B deployed, funded by $366M MSTR ATM + $2.18B STRC issuance. Third-largest weekly buy in company history.
April 20, 2026 (market close)
Total holdings hit 815,061 BTC, passing BlackRock's IBIT at 802,823. First time a public-company treasury holds more BTC than the largest spot ETF. MSTR equity fails to rally on the news.
Forward: Q2 2026
Saylor's "think even bigger" framing plus the preferred-stack capacity keeps the 1,000,000-BTC year-end target on the table. Roughly 185,000 coins to go at an average $75K implies ~$13.9B of further issuance if funded at current mix.
Below current spot ~$75,657 — position already above water
MSTR stock reaction

The counter-signal — mNAV premium starting to compress
Why 815,061 matters: until this week the largest single holder of Bitcoin outside self-custody was a spot ETF — a pass-through vehicle with no directional conviction, just inflows. Today it's a public-company treasury that is publicly telegraphing more buying. In plain terms: the largest programmatic BTC buyer on the planet is no longer a fiduciary aggregator, it's a CEO with a narrative.
Source Divergence — Where the Reporting Splits
What each source emphasizes
CoinDeskLeads with the mechanics: 34,164 BTC, $2.54B, $74,395 avg, third-largest buy ever. Straight disclosure framing.
The BlockAnchors on the "think even bigger" Saylor post as the editorial hook and treats the weekly buy as its concrete realization.
Bitcoin MagazineTakes the BlackRock flip as the headline — "Strategy surpasses BlackRock" — and treats the Saylor narrative arc as the lede.
CoinGapeEmphasizes the $2.54B size vs BlackRock's 802,823 BTC in direct comparison. Wire-style headline framing for the pass.
TipRanks / BitcoinEthereumNewsBoth lead with the MSTR stock's failure to rally. TipRanks headline: "Is Saylor Being Silly?" — directly questioning the mNAV premium. This is the bearish cut of the same facts.
Signal vs Noise
Signal
▲Strategy accumulation is accelerating into the Iran ceasefire stack. The firm bought $2.54B during the same week Hormuz reopened and the ceasefire came under strain. That's deliberate — either conviction in the floor or willingness to average up through macro vol. Either reading is bullish for the structural BTC bid.
▲Passing BlackRock is a narrative milestone that reframes the "ETFs own BTC" thesis. For 18 months the accepted story was: ETFs are the marginal buyer. Today the largest non-self-custody holder is a single public company with a stated 1,000,000-coin target. Policy discussions around BTC concentration risk now have a concrete reference case.
⚠The flat MSTR reaction is the counter-signal. TipRanks framing the news as "is Saylor being silly?" is the sell-side crack in the treasury-premium story. If MSTR keeps failing to bid on new purchases, the preferred-and-ATM funding machine gets harder to roll, and the 1M-coin target timeline stretches. Watch for an STRC pricing print or an ATM pause.
▲Polymarket "BTC > $75K in April" locked at 100% while $80K sits at 31% — the market is pricing that Strategy's buying defends the level but doesn't squeeze higher. That's a specific, tradable take that matches the structural-strength-but-range-bound reading.
Noise
"Saylor is pumping on top of the news cycle." Buying size has scaled with the preferred stack — it's programmatic issuance cycling into BTC, not trading. Also noise: conflating the flat MSTR reaction with a bearish signal on BTC. The asset is doing what it needs to do ($75K holding into a geopolitical shock); the equity is doing what mNAV-compression math says it should.
Bottom Line
Strategy now holds more BTC than BlackRock's IBIT — 815,061 vs 802,823 — and did it with the third-largest weekly buy in company history. The size (34,164 coins, $2.54B) and the funding mix ($366M equity + $2.18B preferred) tell you Saylor's capital-stack machine is still operating, and the "think even bigger" post plus the 1M-coin target tell you it's not slowing. Polymarket "BTC in April ≥$75K" is already locked at 100%; the $80K tier at 31% is the live call.
The MSTR equity flatness is the watch-item. If it persists, expect the sell-side to start modeling a harder ceiling on the ATM+preferred funding pace — and that's where the 1,000,000-coin timeline gets tested. For now, the BlackRock pass is a durable narrative shift: the biggest programmatic BTC buyer is no longer a fiduciary inflow machine, it's a public-company treasury with a megaphone.
