Float locking
Float locking is removing shares from the freely tradable supply — through lock-ups, nominee holdings, or coordinated refusal to sell or lend — so that ordinary buying moves the price far more than the company's size would suggest.
How does float locking work?
Float locking makes a security artificially easy to move, and then hides the fact that it has done so.
The price impact of any purchase depends on how much stock is available at nearby prices. A company with 300 million shares outstanding is not necessarily liquid — if 280 million of those are held by insiders, are restricted, or belong to holders who will not sell at any realistic price, the effective supply is 20 million, and the stock behaves like a much smaller company.
An operator who controls most of that 20 million controls the price. Not by displaying anything false, and not by trading deceptively — simply because there is nothing else on the offer.
The mechanics are unremarkable individually.
-
Acquire the tradable supply. In the open market, or directly from the issuer under an exemption, or as consideration in a reverse merger.
-
Split it up. Across nominee accounts, offshore entities, family members and corporate vehicles, arranged so that no single holding crosses the five per cent beneficial ownership reporting threshold.
-
Keep it off the market. Do not sell. Do not lend. Where a broker lends by default, instruct them not to.
-
Let the illiquidity do the work. Modest buying now moves the price several per cent, which is what makes the promotional campaign that follows look like evidence rather than assertion.
Step 2 is the one that makes it a scheme. Concentrated ownership disclosed is a fact the market can price. Concentrated ownership concealed is a trap, because every buyer is transacting on a false picture of how much stock exists to trade.
A worked example with real numbers
A company reports 300 million shares outstanding at $3.10, giving a headline market capitalisation of $930 million.
| Component | Shares |
|---|---|
| Restricted and insider holdings | 218,000,000 |
| Held by the operator group across nominees | 62,000,000 |
| Genuinely available to trade | 20,000,000 |
| Operator’s share of the available float | 76% |
The published float figure might be 82 million — shares outstanding less disclosed insider holdings. The real number is 20 million, because the operator’s 62 million never appears anywhere.
What that does to price impact. With roughly 400,000 shares resting across the top few price levels:
Buying 200,000 shares consumes half the visible book
Resulting move ≈ +4%
Capital required ≈ $620,000Six hundred thousand dollars moves an apparently billion-dollar company four per cent. Repeat over twenty sessions and the price is up 40% on total buying of around $12 million — against a “capitalisation” of $930 million.
The exit problem, which is the whole difficulty. The operator now wants to sell 62 million shares into a market whose entire tradable float is 20 million. It cannot be done. Selling even a fraction collapses the price they built.
This is why float locking almost never appears alone. It is the supply-side preparation for a pump and dump: the promotional campaign exists to manufacture the demand the operator needs in order to exit, and the locked float is what makes the campaign’s price action credible.
Note also what the numbers say about “market capitalisation” in these situations. Multiplying a thin-market price by the full share count produces a figure with no economic content whatsoever. That arithmetic error is doing an enormous amount of work in both microcap equities and crypto.
Why is float locking illegal?
Owning shares is lawful. Not selling them is lawful. Not lending them is lawful. Each element in isolation is unimpeachable, and that is precisely why the enforcement route runs through disclosure rather than through the conduct itself.
Section 13(d) of the Exchange Act requires anyone acquiring beneficial ownership of more than five per cent of a registered class to disclose it promptly, along with the source of funds and their purpose. Beneficial ownership follows economic reality, not the name on the account — so an operator holding 62 million shares across a dozen nominees owns 62 million shares for this purpose, and a group acting together is treated as one holder. Splitting a position to defeat the threshold is itself the violation, and it is provable from account records without litigating anyone’s state of mind.
Section 16 adds reporting and short-swing profit disgorgement for holders above ten per cent.
Section 9(a)(2) and Rule 10b-5 reach the manipulation where the scheme as a whole can be established — the concealed control, the resulting artificial liquidity, the promotional campaign, and the distribution. This is the charge that captures what actually happened, and it is usually brought alongside the reporting charges rather than instead of them.
Securities Act § 5 frequently applies as well, because the eventual sale of a concealed control block into the public market is an unregistered distribution. That is a strict liability provision: no deception need be proved.
The crypto analogue is structurally identical and legally messier. Token supply concentrated in team and early-investor wallets, with a small circulating float, produces exactly the same price amplification. Where the token is a security the analysis above applies unchanged; where it is not, the disclosure provisions have no purchase at all, and enforcement depends on the general fraud statutes.

How does float locking get detected?
Float reconstruction. Transfer agent records, custodial holdings and filings are used to establish how much stock could actually trade, as against the published figure. The gap between the two is the finding.
Nominee linkage. Common funding sources, shared addresses, sequential account openings, common authorised traders, and the same lawyer or corporate services provider across supposedly unrelated entities.
Price impact analysis. Measuring how far the price moves per dollar traded, compared with peers of similar reported size. A stock that moves like a $20 million company while reporting a $930 million capitalisation has a float problem, whatever the cause.
Holder-base tracking. Appreciation with no change in the number of recorded holders means the buying is coming from a small, closed set.
Order book asymmetry. Persistent thinness on the offer side, unexplained by anything about the company, is the observable consequence of supply that has been withdrawn.
- A share count that is large while the quantity actually available to trade is a small fraction of it.
- Holdings distributed across nominees and offshore entities that would breach disclosure thresholds if aggregated.
- Transfer agent records showing concentrated ownership that never appears in beneficial ownership filings.
- Lock-up agreements or consulting share issuances timed to precede a promotional campaign.
- Displayed offer-side depth that is persistently and inexplicably thin relative to bid-side depth.

What are the red flags?
- A price that moves several per cent on trivial volume, repeatedly.
- A company whose reported shares outstanding bear no relation to how much stock actually trades.
- Sharp price appreciation with no change in the number of recorded holders.
The most useful single check is the ratio of dollar volume to reported market capitalisation. A company that reports a billion-dollar valuation and trades a few hundred thousand dollars a day is not a billion-dollar company in any sense that matters; it is a small float with a large multiplier applied to it.
What float locking is not
It is not long-term holding. Most shares in most companies are held by people who rarely trade. That is normal and healthy.
It is not a small float. Plenty of legitimate companies have concentrated registers and thin trading. The issue is concealment plus purpose.
It is not a lock-up agreement. Post-offering lock-ups are disclosed, contractual and ordinary — disclosure is exactly what distinguishes them.
It is not a corner. A corner exploits a delivery obligation. Float locking exploits the absence of supply, and its purpose is usually to enable a later distribution rather than to squeeze anyone.
Frequently asked questions about float locking
- What is the float, exactly?
- The number of shares actually available to trade — shares outstanding less restricted stock, insider holdings and anything else that will not realistically come to market. It is almost always far smaller than the headline share count.
- Is holding a large position and not selling manipulation?
- No. Long-term holders are the backbone of most share registers, and declining to sell is an ordinary exercise of ownership. Float locking is the deliberate removal of supply as part of a scheme to make the price movable, usually with the concealment that requires.
- Why does concealment matter so much here?
- Because a locked float is only useful if others do not know it is locked. A buyer who knew that 85% of the tradable stock was controlled by one group would price the illiquidity accordingly. The undisclosed control is what turns supply concentration into a scheme.
- How is it concealed?
- Through nominee accounts, offshore entities, family members, and structures that keep every individual holding below the five per cent beneficial ownership reporting threshold while the group as a whole is far above it.
- What does a locked float do to the price?
- It amplifies everything. With little stock available, modest buying consumes what depth exists and walks the price up quickly. That is what makes the subsequent promotional campaign look credible: the price genuinely does move.
- Is this common in crypto?
- Very. Token supply is frequently concentrated in team and early-investor wallets, and circulating supply can be a small fraction of total supply. Reported market capitalisations that multiply a manipulated thin-market price by the full supply are meaningless as a result.
- What law is actually charged?
- Usually beneficial ownership reporting under section 13(d), because the failure to disclose is provable without litigating anyone's intent. The manipulation charge under section 9(a)(2) or Rule 10b-5 follows where the scheme as a whole can be established.
- How does a float lock end?
- Badly for the holder, usually. Concentrated stock in an illiquid name cannot be sold without collapsing the price, which is why float locking is nearly always paired with a promotional campaign to manufacture the demand needed to exit into.
