I've been thinking more about this whole Metaplanet dilution issue, the 10th Series and the claim that management has somehow "stolen" Bitcoin from existing shareholders and I think it's worth looking at it from a different angle
I think the discussion is mixing up several different things:
- Dilution
- BTC per share
- Value transfer
- Value creation
And ultimately, shareholder returns
They are related, but they are not the same thing. Each one is a different metric, measuring a different question, and most of the argument I'm reading is people using one to answer another
So let me go through them. What each one actually measures, how to compute it yourself from Metaplanet's own filings, and what it can and cannot tell you
FIRST, THE THING EVERYTHING ELSE DEPENDS ON
Start with something very basic
If Metaplanet owns 43,000 BTC and you own 5 shares, you don't own the amount of Bitcoin represented by those 5 shares
You own 5 shares of Metaplanet
You cannot go to the company, hand over your 5 shares and ask for your corresponding Bitcoin
The Bitcoin belongs to the company
Your asset is the share
What you own is a proportional claim on an enterprise, one that happens to hold 43,000 BTC, plus a securities business, plus an options-income operation, plus whatever it builds next
That distinction is the foundation for everything below, because it tells you what BTC per share actually is...
It is a metric, not a direct claim on Bitcoin
It tells you how much Bitcoin is economically backing each share. It's a measure of backing, and for a Bitcoin Treasury Company it is obviously one of the most important measures there is
But it is still a measure. It is not a balance in your account
Your actual return as a shareholder comes from the value of your shares. You make money if the market value of what you own increases
Which is why I don't think we can simply say:
"BTC per share went down, therefore management stole Bitcoin from shareholders"
The shareholder never owned that Bitcoin directly. Nothing left the treasury. What matters is whether the economic value of the share went up or down
Hold on to that. I'll come back to it at the end, because it's the whole point
METRIC ONE: DILUTION
Dilution measures one thing only: how much your proportional claim shrank
It does not measure whether that was good or bad for you. It literally cannot, because it only looks at one side of the transaction
Here's the standard example:
Imagine a company has 100 shares and 100 BTC
That's 1 BTC per share
The company then issues 100 new shares and raises enough capital to buy 200 BTC
Now the company has 200 shares and 300 BTC
That's 1.5 BTC per share
Your ownership percentage has fallen from 1% to 0.5%
You've been diluted
But your individual share represents MORE Bitcoin than before
So was the dilution bad?
Not necessarily. In fact the transaction was highly accretive to you
This is why the number of shares issued, on its own, tells you almost nothing. The important question is what the company received in exchange for them
If it receives $100 and creates $150 of value, dilution is accretive. If it receives $100 and creates $50, dilution is destructive. The same share count produces opposite outcomes
So dilution is a real metric, but it is an input, not a verdict
METRIC TWO: THE ACCRETION MULTIPLE
This is the one that turns dilution into an answer, and almost nobody uses it
It asks: how much Bitcoin did each new share bring in, relative to the Bitcoin each existing share already had?
A multiple of 1 means the raise changed nothing per share. You were diluted and got nothing for it
A multiple of 2 means every new share arrived carrying twice the Bitcoin backing of an existing one. That's the example above
A multiple below 1 means the raise actively reduced BTC per share
And here's the useful part. There is an exact identity linking the multiple to the two things Metaplanet already reports:
BTC Yield = dilution × (accretion multiple − 1)
which rearranges to:
accretion multiple = 1 + (BTC Yield ÷ dilution)
This is not a model. It's arithmetic. Nothing is assumed, nothing is estimated, no market data is required. Metaplanet publishes dated Bitcoin holdings, issued shares and fully diluted shares in the KPI table attached to every single "Notice of Additional Purchase of Bitcoin" [1]. Feed those in and the multiple falls out
Anyone can run this. That's why I like it
USING IT: WHAT EVERY RAISE ACTUALLY DID
Pull every one of those notices and you get fifteen dated observations, rather than the eight quarter-ends most people work from. The resolution matters, for a reason you'll see in a second
Each line below reads: period, new shares issued, dilution taken, change in BTC per share, resulting multiple

Now look at what that tells you that "they issued a lot of shares" never could
The final quarter of 2024 brought in Bitcoin at nearly 44x the backing each existing share already had, on just 7.2% dilution; because it came from debt, from options income, and from small amounts of very expensively placed stock. The first half of 2025 ran at 7.45x and 5.25x. Those raises transformed the company
And some raises did much less. Which brings me to the resolution point
WHY GRANULARITY CHANGES THE ANSWER
Between 8 and 30 September 2025, issued shares rose by exactly 385,000,000 [2]. Not a single warrant was exercised in that window, so the international offering is cleanly isolated
On its own, it scores 1.05x
At quarterly resolution that same offering disappears. The September 2025 quarter comes out at 1.78x, because the offering gets averaged with the July and August warrant exercises that scored 2.04x to 13.48x. The blend hides both facts: the exercises look worse than they were, the offering looks much better than it was
That's a general lesson about these metrics, not a point about Metaplanet. Measure at the wrong granularity and you get a number that describes no actual transaction
The obvious objection is timing: money takes weeks to become Bitcoin. So extend the window and let the proceeds land
- Measured to 30 Sep 2025
33.6% dilution
+1.7% BTC/share
= 1.05x
- Measured to 31 Dec 2025
34.7% dilution
+13.8% BTC/share
= 1.40x
- Measured to 30 Jun 2026
41.6% dilution
+24.8% BTC/share
= 1.60x
Nine months later, with every satoshi of the proceeds deployed, it's 1.60x. The same treatment on the January-to-March 2026 raise takes it from 1.28x to 1.91x
And here's the finding that the metric produces which most of the debate has skipped entirely:
NOT ONE RAISE DESTROYED BITCOIN PER SHARE
There is no line in that list below 1.0x. Every single raise, including the ones that barely moved the needle, left each existing share backed by more Bitcoin than before
Whether the dilution helped shareholders isn't actually in question. How much it helped, and when, is
METRIC THREE: BTC GAIN, WHICH MEASURES VALUE CREATED
Dilution measures what you gave up. The accretion multiple measures the quality of a single raise. Neither one tells you the cumulative result
That's what BTC Gain is for. Metaplanet publishes it: the extra Bitcoin the strategy generated for shareholders after stripping out dilution. By construction it's the part that accrued to existing holders rather than to the new ones
Sum every quarter from the pivot through 30 June 2026 [6][7] and you get approximately 19,940 BTC of value created, net of dilution. At roughly $80,000 per Bitcoin, about $1.6 billion, by a company that four years ago had negative net worth and a going-concern warning in its accounts [3]
That's the number that answers "did this work?" It's a different question from "was I diluted?", and it has a different answer
NOW THE 10TH SERIES, READ THROUGH THESE METRICS
The 10th Series was created in 2022/23, when this was Red Planet Japan: a hotel business gutted by the pandemic, negative net worth, going-concern warning [3]. The original pool was roughly 46 million potential shares [11], and the team bought those rights with their own money, ¥54,950,000, declared as own funds, no borrowings [5], approved by special resolution at a shareholders' meeting [4]
But the structure contained an adjustment clause: the pool expanded automatically as the fully diluted share count grew, adding one pool share for every four issued to investors
That ratio is verifiable rather than assumed. Over the third quarter of 2025, issued shares rose by 486,260,000 while the gap between issued and fully diluted widened by 121,565,000 [3]. Exactly 25%
The pool eventually reached 319,464,000 potential shares [3], almost seven times the original grant. The clause has since been deleted and the pool fixed at that number, with the resulting shares locked until 17 August 2031 [8]
Now apply the metrics
Metaplanet has 43,000 BTC and 1,281,308,624 issued shares [7]. That's approximately 3,356 satoshis of Bitcoin backing each share
If the entire 319,464,000 potential shares were exercised and the Bitcoin balance stayed at 43,000, the figure would fall to roughly 2,686 satoshis per share
The drop is 670 sats, or 20.0%. Which is the same answer you get from the other direction: the pool is 19.59% of the fully diluted count. Two routes, one number. Good sign the arithmetic is sound
So yes, the 10th Series is significant. I'm not arguing it doesn't matter. It has a substantial effect on fully diluted BTC per share, and unlike every raise in that list above, it brought in no capital and no Bitcoin. It's a compensation instrument, not a financing
But read what actually happened, in the language of the metric
WHAT DID AND DID NOT HAPPEN
The Bitcoin has not been removed from Metaplanet. The company still owns all of it. Every satoshi is still on the balance sheet, and 43,000 is 43,000 whether the 10th Series exists or not
What changed is the number of shares over which that same treasury is divided
That's the entire mechanical event. The numerator didn't move. The denominator did
So the difference between 3,356 sats and 2,686 sats doesn't mean shareholders had 670 sats taken from them
Those 670 sats were never sitting in anyone's brokerage account. Nobody ever owned them. They are the difference between two possible capital structures, one where the pool exists and one where it doesn't
That distinction sounds pedantic and it isn't, because it determines which question you're actually asking
You can say: "The 10th Series reduces the BTC per share that existing shareholders would otherwise have had." True, and measurable: 20.0%
You can say: "The 10th Series represents a transfer of economic value to management and other beneficiaries" Also true. The pool holds a claim of 19.59% of the company, which on today's treasury corresponds to roughly 8,420 BTC of backing, around $674 million at current prices. That's a real number and it's a legitimate thing to argue about
But saying "management stole X BTC from shareholders" is a different claim, and it requires something neither of these metrics can give you
You would have to establish that the value transferred was unjustified relative to the value created
And that is no longer a dilution question at all. It's a compensation question, which means comparing what they received against what a properly designed incentive plan would have paid for the same performance. That's a real analysis, it's answerable, and it deserves its own piece rather than being smuggled in under a metric that was never designed to carry it. I've worked through it separately
What I want to establish here is narrower and, I think, prior to all of it: the metrics tell you the pool is large and that it dilutes backing per share by 20%. They do not, on their own, tell you it's theft. Those are different findings that require different evidence
THE LIMIT OF THE METRIC ITSELF
There's one more thing worth saying, because it's a limitation of BTC per share that applies regardless of what you conclude about the 10th Series
Maximising BTC per share at every single moment is not obviously the objective
You want it to rise, of course. But Bitcoin sitting on a balance sheet doesn't have to be the end of the story, and BTC per share can only ever measure the balance sheet
In June 2026 Metaplanet agreed to acquire Siiibo Securities for ¥2.1 billion [9], a licensed Type I financial instruments business, since renamed Metaplanet Securities. That's a distribution channel for Bitcoin-linked products that the group owns rather than rents
In August it agreed to contribute 2,100 BTC and $2.5 million to Super League Enterprise for roughly 95.7% of the company, everything locked for five years [10]. On closing, subject to a shareholder vote, that becomes Superplanet
And the options-income business is already inside the numbers above: part of what produced that 43.86x quarter in late 2024 was income generation, not share issuance
If those work, Bitcoin stops being a passive reserve and becomes productive capital. The flywheel is roughly: more capital, more BTC, larger balance sheet, more products and income, more capital, more BTC
And then the economic value of holding 43,000 BTC isn't capped at the market value of 43,000 BTC. The balance sheet becomes the foundation of a business
Which changes how you read dilution. If a new share lets the company acquire productive assets or build something that creates more value than the dilution costs, you can be diluted and considerably better off. If management keeps issuing while extracting value for itself without creating enough in return, the dilution becomes a serious problem
Notice also what those two transactions have in common: neither required issuing Metaplanet common stock. The phase where common equity was the only instrument available; because a company worth $17 million has no bond market, no preferred market and no acquisition currency, is the phase that generated this entire argument. It's ending on its own
SO WHICH METRIC ANSWERS WHICH QUESTION?
Not "was there dilution?" Of course there was. That metric is an input
Was the capital deployed efficiently?
- Metric: Accretion multiple, raise by raise
- Answer: mostly yes, sometimes spectacularly, and in a handful of raises, barely
Did it increase BTC per share?
- Metric: BTC per share
- Answer: yes, in every measured period without exception.
How much value was created?
- Metirc BTC Gain
- Answer: about 19,940 BTC net of dilution, roughly $1.6 billion in eight quarters
How much does the 10th Series shift?
- Metirc the pool's share of the fully diluted count
- Answer: 19.59%, about 8,420 BTC of backing, ~$674 million
Is that reasonable relative to the value created?
None of these metrics. That one needs a compensation benchmark, and it's a separate argument
Can Metaplanet turn a growing balance sheet into a business that compounds value per share?
No metric yet. That one is genuinely open, and it's the one that decides what your shares are worth in five years
Because ultimately, that's what shareholders own. Not a fixed number of Bitcoin. They own shares in a company, a company that holds 43,000 BTC and is trying to build something on top of them
Nobody took Bitcoin out of the treasury. What moved was the denominator of the metric that measures how much of that treasury stands behind each share
That is worth measuring carefully, and worth arguing about seriously. It is not theft, and calling it theft costs you the ability to make the real argument
And the real investment thesis was never simply that Metaplanet will own more Bitcoin
It's that management can make the economic pie grow faster than the number of slices
The question isn't whether shareholders were diluted
It's whether, after all the dilution, the piece they own is becoming more valuable
