Retail traders can now take leveraged bets on OpenAI’s pre-IPO valuation through a synthetic perpetual futures contract on Aster, the multi-chain decentralized perpetual exchange. The product, trading under the ticker $OPENAI, offers up to 5x leverage and tracks market-implied share prices of the AI giant.

How the synthetic contract works

The $OPENAI perpetual contract is entirely synthetic. It does not represent direct ownership of underlying shares, does not confer equity rights, and has no connection to OpenAI’s actual cap table. Instead, the contract uses oracle-driven implied valuations to track what the market believes OpenAI shares are worth.

This matters because OpenAI has actively discouraged unauthorized trading of its shares on secondary markets. Synthetic products sidestep that friction entirely, since no actual equity changes hands.

Aster launched the $OPENAI contract on May 26, following a similar synthetic perpetual for SpaceX ($SPCX) that went live on May 18. Both products offer the same 5x leverage ceiling. A promotional trading multiplier of 1.2x was available until June 2 to incentivize early volume.

The timing is not accidental. OpenAI is reportedly preparing a confidential IPO filing, with valuation expectations hovering around $1 trillion. SpaceX, meanwhile, has filed an S-1 targeting a potential $1.75 trillion valuation on Nasdaq.

A broader trend across crypto exchanges

Aster is far from alone in this space. A wave of pre-IPO perpetual contracts has swept across crypto platforms since May 2026. OKX, Binance Futures, Crypto.com, and others have all launched analogous products targeting OpenAI, SpaceX, and Anthropic valuations.

Pre-IPO shares of companies like OpenAI have historically been the exclusive playground of venture capitalists, accredited investors, and select secondary market platforms. Synthetic perpetuals change that calculus by removing the accredited-investor requirement entirely.

What this means for traders and the broader market

The 5x leverage ceiling is relatively conservative by crypto perpetual standards, where some platforms offer 100x or more. Pre-IPO valuations are inherently speculative, driven by secondary market transactions, rumor, and sentiment rather than public financial disclosures.

Traders should understand that these contracts track implied valuations, not actual share prices. The oracle mechanisms feeding price data into these contracts are only as reliable as the data sources they pull from. There’s also the regulatory dimension: synthetic derivatives on private company valuations occupy a gray zone that regulators have not fully addressed, and none of these platforms offer investor protections such as SIPC insurance or standardized disclosure requirements.
