On Sept. 9, Binance’s pre-IPO perpetual contract for Anthropic traded above $2,100, reaching an implied value that exceeds $2.1 trillion based on Binance’s estimated one-billion-share denominator.
Real traders are pricing exposure to Anthropic on Binance, but both the mark and the share-count convention behind the trillion-dollar figure belong to the contract, so the venue sets the price.
A DefiLlama snapshot at 14:45 UTC on Sept. 9 showed the contract at $2,168.26, with $26.1 million in open interest and $24.76 million in 24-hour volume. A later ByKaranteli snapshot put the mark at $2,122.74, recorded open interest up 6.1% over 24 hours, and counted about $243,000 in liquidations.
Those figures show measurable activity in a derivatives market, with tens of millions of dollars in contract activity producing a company-wide number measured in trillions.
| Measure | Current reference | What it can establish |
|---|---|---|
| Binance contract mark | Above $2,100 on September 9 | The price of the leveraged contract on that venue |
| Share denominator | One billion, estimated by Binance | The convention used to express an implied company value |
| Latest disclosed private valuation | $965 billion in May | The price of Anthropic’s Series H financing |
| IPO filing status | Confidential draft S-1 submitted | Anthropic has started the process, but public offer terms are not set |
| Future anchor | Third-party index after an official listing | A potential external reference for the converted contract |
What traders are pricing and why it is fragile
Binance Research said the contract briefly produced an implied value near $2 trillion in August and closed August 31 near $1.9 trillion when its price was multiplied by the exchange’s estimated one-billion-share denominator.
The exchange’s research arm described that level as roughly twice Anthropic’s Series H valuation and around 30 times the revenue run rate used in its report.
One side is a continuously traded derivative quote multiplied by a provisional share count, and the other is a financing valuation negotiated for private securities.
Anthropic said its May 28 Series H raised $65 billion at a $965 billion post-money valuation and that its run-rate revenue had crossed $47 billion earlier that month.
Those May disclosures set a historical benchmark for company-announced financing and operating metrics, but they do not validate the denominator used by the perpetual.
Binance’s contract announcement specifies an estimated one billion shares. Its accessible official announcement mirror says the actual total may differ and warns that Binance does not endorse the resulting implied value.
Traders are willing to take risk at prices that imply a substantial premium to Anthropic’s May financing when the Binance denominator is applied.
The ANTHROPICUSDT contract cannot reference a widely observed stock price before Anthropic lists because no public Anthropic share index exists.
Binance’s published method uses a 10-second average, reaches further back when transactions are sparse, and limits the mark’s movement to 1% per second. This is price discovery for the Binance contract, shaped by its participants, collateral rules, and liquidity rather than by an equity market.
Binance permits up to 20x leverage on ANTHROPICUSDT. Its pre-IPO terms call for funding every eight hours at +0.005% per interval, while adverse moves or unmet margin calls can liquidate collateral.
Leverage lets traders express a position larger than the capital committed and can turn price moves into forced transactions. The Sept. 9 snapshots show positions were being opened and liquidated, although they do not show that liquidations caused the price to move or that the market could absorb a large order without moving.
The contract also does not represent ownership in Anthropic and is not sponsored or endorsed by the company. No public share price is pulling the pre-IPO mark back toward a redeemable underlying asset.
Coinbase’s general explanation of pre-IPO perpetuals describes the broader market-structure constraint: private-share liquidity is fragmented, physical shorting is difficult, and a pre-IPO contract can diverge from private-market quotes or indicative IPO pricing, especially when trading is thin.
Together, those features make the market informative but not authoritative.
What can reset the anchor for Anthropic’s price
A revised share count can change the contract’s screen price without necessarily changing a position’s value. Binance has documented that it may rescale both mark price and position quantity when a revised or actual denominator becomes available, while seeking to preserve notional value.
If the estimate rises from one billion shares to a much larger number, the per-contract quote can fall mechanically as the quantity rises proportionally. A trader who treats the quote as a stable share price could mistake that technical change for an economic loss.
OKX announced that it would change the estimated denominator for its own ANTHROPICUSDT contract from one billion to 10 billion. The exchange called the adjustment value-neutral and explicitly said it was unrelated to Anthropic’s share count.
The larger economic reset will come from public information about the offering and from a listed market. Anthropic said on June 1 that it had confidentially submitted a draft Form S-1, while noting that the number of shares to be offered and the offer price had not been set.
Reports from Sept. 4 noted that marketing was expected to begin in mid-October at the earliest and that a public prospectus was expected in late September. The report cautioned that the timetable could change, and Anthropic declined to comment.
Public filings and an eventual offering can introduce a disclosed capital structure, a marketed price range and, after listing, an observable stock price. Binance says it may transition the pre-IPO instrument to a standard TradFi perpetual when it determines that a stable third-party index is available, with the mark gradually converging after notice.
ANTHROPICUSDT shows that traders will risk real capital on Anthropic exposure at extraordinary levels. But until an IPO supplies offer terms and an external index, its implied valuation remains a product of Binance’s own market, leverage rules, and estimated denominator.
