Michael Saylor just built a $1.2 billion yearly dividend bill on a business that makes no money.
And it's getting bigger every month.
Strategy has issued $11.3 billion of preferred stock across 5 different series since January 2025.
The rates are brutal: 8% to 11.5%.
Here is what he owes every year:
- STRC: $731M at 11.5%
- STRD: $135M at 10%
- STRF: $128M at 10%
- STRK: $112M at 8%
- STRE: $89M at 10%
Total: $1.2 billion per year. In cash. Forever.
The software business? It lost $112 million in free cash flow last year. It cannot pay a single month of these dividends.
So where does the money come from?
Issuing new MSTR shares. Every dollar of dividends is funded by printing more common stock.
Saylor has pre-funded the next 2 years with a $2.25 billion cash reserve raised from share issuance.
But new preferred stock is being issued every single week. The reserve will run out.
And there is still $30.5 billion of preferred capacity left. If he uses it, annual dividends could hit $4 billion per year.
On April 12, Saylor said Bitcoin only needs to grow 2.05% per year to cover everything.
The math is correct.
But dividends are paid in cash. Bitcoin appreciation is not cash.
To turn Bitcoin gains into cash, he has only 3 options:
1. Sell Bitcoin (he has promised never to do this)
2. Issue more MSTR shares (destroys shareholder value when stock trades below NAV)
3. Turn off dividends (STRF and STRE dividends escalate to 18% if unpaid)
Right now MSTR trades at 0.79x its Bitcoin NAV. A 21% discount.
This means every new share issued destroys Bitcoin per share. The flywheel that worked on the way up is now running in reverse.
There is also $6.8 billion of convertible debt with holder put options exercisable by September 2028.
If the stock stays low, bondholders can demand cash repayment. The reserve cannot cover both dividends and puts.
The breakeven was 1.5% in February. It is 2.05% today. At current issuance pace it could be 3.4% by year end. The number Saylor presents as fixed is actually rising every month.
Bitcoin does not appreciate at 2.05% per year in a straight line.
It goes up 300% then crashes 77%. Dividends are due every month regardless of where Bitcoin is in the cycle.
This is a timebomb. It does not need Bitcoin to fail.
It only needs Bitcoin to be volatile on a timeline that meets $1.2 billion in annual cash obligations.

The Generative AI Data Scientist career screener in 2026:
❌ You don’t need a PhD
❌ You don’t need months of math
❌ You don’t need “3 years experience”
✅ You need proof you can ship AI/DS projects:
1. One AI/ML project that solves a real business problem
2. Decision-ready output (not “here’s a chart”)
3. A workflow the business can rerun (not a one-off notebook)
That’s what separates ML modelers from AI/DS System Builders.
Want the pattern? I’m teaching it live (free):

Data engineering will start feeling like Microsoft excel soon enough!
- data pipelines generated with Claude Code: companies threatened: Informatica, Talend, Fivetran
- physical data modeling managed by Databricks liquid clustering
Companies threatened: senior data engineers who pride themselves on data modeling, Snowflake
- automated data analysis by heavy LLM models
Companies threaten: Accenture, Tata Consultancy Services, Infosys, McKinsey & Company
- visualization frontends simplified and more customized
Companies threatened: Tableau, Salesforce, Preset
- sprint management done with agents
Companies threatened: Atlassian, Linear, Notion
The transformation we’re seeing is really intense. I’m excited to see where things end up!
What else do you see going away or changing a lot?
