How Pre-IPO Perpetuals Work: Index Pricing, Funding, and Risks

Pre-IPO perpetuals are among the newest instruments in crypto derivatives, and they are also among the most poorly explained. This guide sets out, in plain terms, what they are, how their pricing actually works, and what to watch for before trading — without hype and without shortcuts. If you are evaluating a contract such as the Anthropic or OpenAI pre-IPO perpetual on WEEX, this is the place to start.

What a pre-IPO perpetual is

A pre-IPO perpetual is a synthetic, cash-settled derivative. It is margined and settled in USDT, and it gives you price exposure that references a private company's market-implied valuation. It is a forward-type contract with no fixed expiry date.

The word synthetic is doing real work here. When you hold a pre-IPO perpetual you do not own any equity in the referenced company. You have no shareholder rights, no voting rights, no dividends, and no claim on the company or its assets. What you hold is a contract whose value rises and falls with a published index — and your profit or loss is settled entirely in USDT. Exposure to a price is not ownership of a business, and the two should never be confused.

Why these instruments exist

Some of the most closely watched companies in the world remain privately held. Anthropic, the maker of Claude, and OpenAI, the maker of ChatGPT, are both private companies. Their equity is not listed on any stock exchange and is not publicly tradable anywhere.

That creates a structural gap: there is broad interest in how these companies are valued, but no open market in which to express a view. Pre-IPO perpetuals are one response to that gap. They let a trader take a long or short position that references a private company's implied valuation, settled entirely in USDT, with no transfer of actual equity at any point. For a contract-specific walkthrough, see our explainers on the Anthropic pre-IPO perpetual and the OpenAI pre-IPO perpetual.

How pricing works

Every pre-IPO perpetual on WEEX has a live index price, published per contract. The index price is the reference the contract is designed to track; it is distinct from the mark price used for margining and liquidation. Both are published, and it is worth learning to read them separately.

Here is the difference that matters most, compared with a listed stock. A public stock has a continuous public market — buyers and sellers transacting throughout the trading day, producing a single visible price. A private company has no such market. Instruments of this class typically anchor their index to private-market valuation signals, such as the pricing implied by funding rounds and secondary-market activity. Because those signals are periodic and indirect rather than continuous, the resulting index is best understood as an estimate of value, not a live quote from an open exchange.

One consequence follows directly from that design: tracking deviation is inherent. The contract's traded price can move away from any external estimate of the company's private-market valuation, and there is no continuous public price to pull the two back together. This is a structural feature of the instrument class, not a malfunction — and understanding it is essential before you place a trade.

Contract mechanics: funding, leverage, fees, and caps

WEEX lists two pre-IPO perpetuals, and they share most of their rules; leverage is the main point of difference. Both are USDT-margined, forward-type contracts listed under the Pre-IPO tab.

Funding is the mechanism that keeps a perpetual anchored to its index over time. Three times a day — at 00:00, 08:00, and 16:00 UTC — long and short holders exchange a funding payment. When the contract trades above its index, longs typically pay shorts; when it trades below, the flow reverses. Funding is a recurring cost or credit that you carry for as long as the position is open, and it is entirely separate from trading fees.

Leverage amplifies both gains and losses. A pre-IPO perpetual can be traded from 1x up to 20x on ANTHROPICUSDT, or up to 50x on OPENAIUSDT; the higher the leverage, the smaller the adverse move needed to trigger liquidation. The ±5% order price band limits how far from the reference an order can be placed, and the 80-contract position cap limits how large a single position can grow. Those caps are not arbitrary — they reflect the finite liquidity of the instrument.

What happens at an IPO

A natural question is what becomes of a pre-IPO instrument if the referenced company goes public. The honest, class-level answer is that it depends on the platform's official announcement at the time. When a referenced company lists publicly, platforms resolve their pre-IPO instruments according to those announcements — for example by transitioning a position to a standard contract or settling it. There is no single automatic outcome that applies to every instrument.

A useful worked example comes from WEEX's own record with SpaceX. WEEX ran a SpaceX US-stock perpetual (SPCX) from May 2026. SpaceX listed on NASDAQ on June 12, 2026, and the contract continued through the event: it was briefly set to reduce-only while the underlying share count was updated, and its leverage was later raised. WEEX subsequently listed tokenized SpaceX stock on the spot side after the IPO. As of July 2026, WEEX lists nearly 300 TradFi perpetuals and more than 70 tokenized-stock spot pairs, so a post-listing spot product is part of an established pattern. That arc illustrates one way a listing can be handled — it is not a promise about how any other contract will be treated.

For the specific terms that will apply to any given pre-IPO perpetual, always consult the WEEX announcement center. Resolution terms are set by platform announcements at the time of the event, not by this guide.

The risks you need to understand

Pre-IPO perpetuals carry meaningful risks. Read this section in full before trading.

• Tracking deviation. The contract price can diverge from any private-market valuation estimate. Because a private company has no continuous public price, there is no live market to close that gap for you.
• Leverage and liquidation. Leverage magnifies losses as well as gains. At higher leverage a small adverse move can liquidate your position and cost you your margin.
• Funding costs. Funding is charged three times a day. Held over time, those payments can accumulate into a significant carrying cost, regardless of whether your directional view eventually proves correct.
• Liquidity. The order and position caps exist for a reason: the market for these contracts is finite. Large orders can be difficult to fill, and exiting a position may move the price against you.
• IPO-event resolution. If the referenced company lists publicly, the terms that apply to your position are set by platform announcements at that time. Plan for the possibility that trading conditions change.

Important disclosure

Neither Anthropic nor OpenAI is involved in, has authorized, or endorses these products. The contracts reference the companies' names and valuations only; they are not offered, sponsored, or endorsed by the companies in any way. A pre-IPO perpetual is a derivative product offered by WEEX, and holding one gives you no relationship with, and no claim on, the referenced company.
