Binance's Anthropic Pre-IPO Contract Suggests Over $2 Trillion Valuation
On September 9, 2026, Binance launched a pre-IPO perpetual futures contract linked to Anthropic, an AI safety research company. The contract's price surpassed $2,100 per share. Assuming a total share count of 1 billion, as estimated by Binance, this indicates an implied market capitalization exceeding $2.1 trillion—more than double Anthropic's $965 billion valuation at its Series H round in May 2026.
However, this figure is largely theoretical. Binance's total share count is an estimation, and Anthropic currently has no publicly traded shares or direct stock equivalents underpinning the contract's price. The company's IPO documentation remains confidential, with key details such as share volume and pricing undecided.
Trading Activity and Risk Profile in Pre-IPO Futures
At 14:45 UTC on the day of launch, data from DefiLlama showed the contract's mark price at $2,168.26, with open interest at $26.1 million and 24-hour trading volume nearing $24.8 million. Later figures indicated a slight price decline to $2,122.74 alongside a 6.1% increase in open interest and approximately $243,000 worth of liquidations.
Binance allows up to 20x leverage on this product, with funding fees charged at 0.005% every eight hours. The futures' price movements and liquidation activity demonstrate participants are bearing genuine risk. Nonetheless, the contract's price is not anchored to an actual share price but is influenced by Binance's market framework and trader sentiment.
Coinbase has noted the challenges of pricing pre-IPO perpetuals: limited liquidity of private shares and inability to physically short the stock mean futures prices can diverge significantly from private market or eventual IPO pricing, particularly when trading volumes are thin.
Share Count Estimates and Benchmarking Future Pricing
Binance clarifies that its 1 billion share estimate serves solely for pricing reference and does not reflect Anthropic's actual outstanding shares; the implied valuation is not officially endorsed by Binance. Meanwhile, competitor OKX has recently revised its Anthropic pre-IPO contract's share estimate from 1 billion to 10 billion shares, stressing this is a mechanical pricing change without altering the contract's economic value.
Anthropic confidentially filed a draft S-1 with the U.S. Securities and Exchange Commission on June 1, 2026, formally initiating its IPO process. Market speculation places the filing of the prospectus around late September, with a roadshow potentially starting mid-October, though these dates remain tentative.
Once Anthropic goes public, disclosed capital structure and official share pricing will provide a more authoritative reference for valuing pre-IPO derivatives. Binance indicates that upon establishing a stable third-party index, the pre-IPO perpetual contracts may transition into conventional perpetual futures with prices aligning closer to publicly traded benchmarks.
Market Interpretation and Investor Considerations
The high implied valuation in Anthropic's pre-IPO perpetual futures reflects strong investor enthusiasm about its artificial intelligence prospects but also highlights the complexity and uncertain pricing mechanisms in private equity derivatives markets. Traders leveraging these contracts express bullish views but lack concrete public market data backing the prices.
Industry experts caution that while trading volumes are robust, implied valuations are still heavily dependent on contract design and input assumptions. Investors and observers should watch forthcoming IPO disclosures closely to attain more definitive valuation benchmarks.
