STRC Powers Strategy Bitcoin Accumulation Engine

This marked its largest single-week acquisition since the November 2024 post-election surge that followed Donald Trump's return to the White House. The purchase increased total holdings to 815,061 BTC, surpassing BlackRock's iShares Bitcoin Trust (IBIT) for the first time and cementing Strategy as the largest corporate Bitcoin holder in the spot Bitcoin ETF era.

Accumulation engine

The mechanism powering this rapid accumulation is Strategy's at-the-market (ATM) offering programme. An ATM allows a listed company to sell new shares or other securities directly into the open market whenever demand and pricing are favourable, rather than through a traditional large public offering with fixed timelines and underwriter involvement. This converts incoming capital from investors seeking yield or growth directly into Bitcoin on a continuous, rolling basis without lock-up periods.

STRC – Strategy's variable-rate preferred stock instrument, currently yielding approximately 12% annually – has become the dominant funding source in recent weeks. Preferred stock sits between common equity and debt in a company's capital structure: it typically pays fixed or adjustable dividends and has priority over common shares for payments and in liquidation, but usually lacks voting rights.

Preferred equity stability

Among Strategy's suite of digital credit products – preferred stocks that pay monthly cash dividends – STRC stands out for its built-in price-stability design. Unlike conventional preferred shares with a fixed coupon rate, Strategy's board adjusts STRC's dividend rate each month according to a published framework tied to the instrument's five-day volume-weighted average price (VWAP), a common market metric that reflects the average price at which shares traded, weighted by trading volume.

The adjustment rules are mechanical: if the price falls below $95, the dividend rate automatically rises by at least 50 basis points (0.50%). Trading between $95 and $99 triggers at least a 25 basis-point increase. Prices above $101 can lead to a yield reduction. This dynamic yield acts like an automatic stabilizer – when demand weakens and the price dips below the $100 par (face) value, the higher yield attracts income-focused buyers back in.

Launched with a 9.0% yield in late July 2025, the mechanism produced seven consecutive monthly increases through March 2026, adding 250 basis points to reach 11.5%. Preferred shares normally experience a price drop on ex-dividend dates – the day the dividend is no longer included in the share price for new buyers – but STRC's early ex-dates were particularly volatile. It closed August's ex-date at $96.95, fell to $96.90 in September and hit an intraday low of $92.79 in November before recovering.

Recent months show improving stability. Each yield increase has drawn fresh demand, creating a pull back toward the $100 par. Recoveries now often occur within a few trading days and STRC has begun pinning closer to par.

Volume confirms rising confidence. On 13 Apr, STRC saw $1.6bn in trading volume – a record single session – followed by $1.2bn on 14 Apr, with both days closing exactly at $100. Weekly volume from 13-19 Apr exceeded $4.1bn, far above the sub-$100mn average daily levels seen in the instrument's first months. Quiet sessions now routinely clear $300-500mn. The once-experimental preferred has evolved into a deep, liquid market that Strategy can tap at large scale with minimal price impact.

Funding dominance

STRC notional outstanding has expanded 189% year-to-date, from $3bn at the start of 2026 to $8.5bn today, with the majority of growth in the past six weeks. Since March, it has delivered $5.1bn in net proceeds, funding about 73% of Strategy's $7bn in Bitcoin purchases during that window. Last week's $2.5bn BTC buy was financed 86% ($2.2bn) by STRC and 14% by common stock sales. The prior week's $1bn purchase was funded entirely through STRC.

The latest ATM facility, updated on 23 Mar, provides roughly $20bn in remaining STRC capacity – equivalent to about five months at the recent pace. Importantly, the programme is not rigidly capped; Strategy can expand offerings or authorized shares over time. Limits are driven by market demand and economic viability rather than hard ceilings. As long as income investors continue buying at par, evidenced by recent peak weekly volumes exceeding $4.1bn, the accumulation engine can keep running.

Cash flow tension

Strategy's broader digital credit obligations now total $22bn, with STRC representing 39% of that stack. Annualized preferred dividend payments across all series reach $1.5bn, of which STRC alone accounts for $982mn (66%). By comparison, convertible debt – bonds that can be converted into common shares – carries far lower interest costs of just $35mn annually due to their near-zero coupon design.

Cash reserves stand at $2.3bn, sufficient to cover roughly 18 months of current dividends without selling Bitcoin or issuing more equity. However, rapid STRC growth is eroding that buffer quickly; the past two weeks alone added $365mn in new annualized dividend commitments. When reserves tighten, Strategy turns to common stock ATM sales for liquidity. This introduces a structural tension: equity issuance used to buy Bitcoin grows the treasury and is generally viewed as accretive, while issuance used purely to pay dividends increases the share count without adding assets – a dilutive effect.

Residual value for common shareholders

Strategy's 815,061 BTC treasury translates to a headline 213,607 gross Satoshis or sats (the smallest Bitcoin unit, where 100mn sats equal one BTC) per diluted share – the metric often cited by Bitcoin yield advocates. However, common shareholders sit behind senior claims: $8.3bn in convertible debt and $14bn in preferred equity (including STRK, STRF, STRC, STRD and STRE series). These senior instruments have priority for dividends and in any liquidation.

After deducting these fixed-dollar senior claims, the residual Bitcoin exposure for common shareholders varies with BTC's price. At around $75,000 per BTC, residual sats per share have actually declined relative to Q2 2025 levels before STRC scaled significantly. The breakeven price at which STRC issuance becomes accretive to common holders is approximately $91,500 per BTC. Above this level, the added Bitcoin grows the treasury faster than the senior claims in BTC-equivalent terms, ultimately benefiting common shareholders. At $125,000 per BTC, the residual gain reaches +7,659 sats per share versus Q2 2025.

Onchain extension

Roughly $130mn of STRC has moved onchain – meaning recorded and traded on public blockchains – through protocols that wrap the preferred equity into decentralized finance (DeFi) instruments. These allow traditional yield-seeking capital to flow into permissionless liquidity pools.

Two protocols lead to this tokenization. Saturn Credit offers a conservative structure: users deposit USDC, a dollar-pegged stablecoin, to receive USDat, a Treasury-backed stablecoin, then stake sUSDat, which holds roughly 45% Treasuries and 55% STRC for a blended yield. Apyx takes a higher-yield approach with 77% STRC collateral in its apxUSD and apyUSD tokens. Both have integrated with Pendle, a DeFi platform where users trade future yield, currently locking in fixed rates of 12-16% APY depending on the product.
