Corporate treasury giant Strategy has estimated a $4.1 billion income-tax benefit after Bitcoin's fair value rose above its cost basis as of Sept. 30, according to an Oct. 5 SEC filing. The company adjusted its tax accounts by reversing a deferred tax asset and releasing the related valuation allowance, though management noted the figures remain unaudited and unreviewed by KPMG.
Strategy Tax Accounting and BTC Reserves
As of Oct. 4 at 4 p.m. Eastern time, Strategy reported holding 848,000 BTC acquired at an aggregate average purchase price of $75,440.70 per token, including fees and expenses. The tax-accounting adjustment reflects how major valuation shifts impact corporate statements when holdings cross key baseline prices.
While corporate entities track tax balances based on aggregate purchase history, funds evaluate cost metrics differently across their underlying assets and individual share owners.
BlackRock IBIT Cost Basis and ETF Flow Split
Modeling by Maketo estimated the average cost of Bitcoin remaining in BlackRock’s iShares Bitcoin Trust (IBIT) at $81,188 per BTC as of Oct. 2. An Oct. 5 holdings document listed IBIT with 806,038 BTC, representing nearly $69 billion in net assets alongside a Bitcoin benchmark level of $85,694.41.
Historical records from IBIT’s June 30 quarterly filing showed 734,261 BTC held with an investment cost of approximately $61 billion and a fair value of $43.4 billion. During the six months ending June 30, the trust acquired 157,501 BTC and disposed of 192,970 BTC for share redemptions.
Recent market sessions highlighted contrasting flow dynamics. U.S. spot Bitcoin ETFs recorded net outflows of $89.8 million on Oct. 5, even as data from Farside Investors showed BlackRock’s IBIT registered net inflows during the exact same session. This follows broader volatility across institutional products as seen when spot Bitcoin ETF outflows reached $90 million.
Key Takeaways
- Strategy estimated a $4.1 billion tax benefit after Bitcoin crossed its $75,440.70 average cost basis across 848,000 BTC.
- Maketo estimates BlackRock IBIT’s remaining Bitcoin cost basis at $81,188 per token as of Oct. 2.
- Total U.S. spot Bitcoin ETFs saw $89.8 million in net outflows on Oct. 5, though IBIT logged positive inflows.
Why It Matters
When large-scale corporate treasuries and institutional funds move back into profit relative to their cost basis, administrative and tax structures undergo immediate shifts. For corporate holders like Strategy, crossing this threshold eliminates tax asset allowances without requiring asset sales to realize paper adjustments. Monitoring whether primary market redemptions or creations intensify as prices cross fund-level acquisition benchmarks provides crucial data on institutional buyer behavior during market turnarounds.
