OKX Listed OpenAI Pre-IPO Perps on Thursday, on Saturday,…

OKX Europe Markets Ltd, the Malta-regulated arm operating under the Investment Services Act and the European Union's (EU's) Markets in Crypto-Assets (MiCA) framework, listed pre-IPO perpetual futures on OpenAI and Anthropic with up to 10x leverage on 10 September.Two days later, OpenAI Chief Executive Officer (CEO) Sam Altman told Fortune that a 2026 Initial Public Offering (IPO) would be "ill-advised," ruling out a 2026 listing that gave these instruments their reason to exist.The X-Perps, part of a broader rollout that includes roughly 100 tokenized stock and Exchange-Traded Fund (ETF) markets spanning Nvidia, Google, Palantir, SPY, and QQQ, confer "no ownership interest in, or economic claim on, the underlying company's equity," OKX's risk disclosures state.They are bets on a valuation that no regulated market has ever validated, and the listing thesis for one of the two just changed overnight.

Venues Already Disagreed by Hundreds of Billions Before Altman Spoke

Even before the IPO delay, the pre-IPO perpetual market was pricing Anthropic at implied valuations that diverged sharply from its last funding round. Binance and Hyperliquid perpetuals implied roughly $1.93 trillion, while PreStocks carried approximately $1.41 trillion, against a most-recent Series H round that closed at $965 billion, Trending Topics reported. OpenAI perps, meanwhile, traded at roughly 42% above its March 2026 Series F valuation of $852 billion across 18 venues, according to CoinGecko data as of 1 September.OKX Europe CEO Erald Ghoos noted that "pre-IPO markets have been unavailable for most European traders on traditional brokerage and other regulated platforms," positioning the product as access rather than speculation. European derivatives trading volume in X-Perps has increased fourfold since the EU's MiCA transition period ended in July.

Anthropic Pushes Ahead While Its CEO Calls for a Slowdown

The contrast sharpened as Altman spoke. Reuters reported that Nvidia is in talks to invest up to $10 billion as an anchor investor in an Anthropic IPO seeking to raise up to $100 billion at a valuation of around $2 trillion, targeted to price before the November U.S. midterms, according to Reuters.Anthropic's annualised revenue run rate passed $65 billion at the end of July 2026, up from roughly $9 billion at end-2025. NVIDIA's investment, the raise, and the timeline are all reported and not filed; nothing here is confirmed or priced.Yet on the same day, Anthropic CEO Dario Amodei published a statement calling on the industry to "slow the pace at which we improve the capabilities of AI models," warning that rogue AI agent swarms could be "capable of taking over the entire internet with a persistent botnet" within six to twelve months, Axios reported. Altman agreed publicly, stating: "I agree with Dario that we need to pace the frontier."

Price Discovery Without a Cash Market to Anchor It

The trade-desk question these instruments now face is structural, not directional. Pre-IPO perpetuals have no expiry and no underlying cash market, which means there is no arbitrage mechanism to tether the derivative price to a verifiable share value. When the listing thesis shifts, as it did for OpenAI in a single interview, the only price-discovery input is trader sentiment. OKX's own disclosures state that the contract does not provide any ownership interest in, or economic claim on, the underlying company's equity. If the IPO does not proceed, OKX reserves the discretion to delist or settle contracts at prices it determines.The divergence between OpenAI being ruled out for 2026 on safety grounds and Anthropic still heading toward what Reuters described as potentially the largest listing in market history leaves traders holding two sides of the same AI safety coin on a single exchange, with no regulated equity price to discipline either bet. Whether the OpenAI perp marks have repriced since the delay will be the first real test of how these instruments behave when their foundational assumption disappears.
