OpenAI and Anthropic stock CFDs, OPENAIUSD and ANTHUSD, have been tradable on Vantage since 29 June 2026. They track the private market valuations of OpenAI and Anthropic and are listed within the platform’s Crypto Currency category rather than under Share CFDs, so that is where to look for them.
Most ways to get exposure to OpenAI or Anthropic before an IPO, direct secondary shares, SPVs, or platforms such as Forge Global or EquityZen, require accredited investor status.¹ OPENAIUSD and ANTHUSD are structured differently: they are CFDs referencing the private valuation, not a purchase of the underlying shares, so they do not carry that accreditation requirement. That distinction matters, and so does what it does not mean.
Before anything else: these are derivative contracts on a private valuation, not a way to own shares in either company. Trading OPENAIUSD or ANTHUSD does not create equity, voting rights, or any ownership claim in OpenAI or Anthropic. Neither company is affiliated with, endorses, or has any involvement in these instruments.
This piece runs through what OPENAIUSD and ANTHUSD actually track, how they are structured, what happens around a potential IPO, and the full FAQ. Product details below are current as of 06 July 2026 (GMT+8) and are drawn from Vantage’s own product documentation, since these are proprietary instruments rather than publicly traded securities.
Key Points
- OPENAIUSD and ANTHUSD have been tradable on Vantage since 29 June 2026. They are CFDs that track the private market valuations of OpenAI and Anthropic, listed under Vantage’s Crypto Currency category, with no expiration date and daily fees for holding a position.
- These contracts carry no ownership, equity, or voting rights in either company. Price is derived from private market valuations and third-party data providers tracking pre-IPO share transactions, not from a public exchange.
- If either company completes an IPO, Vantage may close positions at a reference price, delist the contract, or transition it to a standard equity CFD, with advance notice provided.
Background: where OpenAI and Anthropic’s IPOs stand
Both companies referenced by these instruments are, as of the current date, partway through their own move toward public markets, which is useful context for anyone trading either instrument.
Anthropic confidentially filed a draft registration statement with the U.S. Securities and Exchange Commission on 1 June 2026, becoming the first major AI lab to formally begin the IPO process.² The filing followed a $65 billion Series H funding round in late May 2026 that valued the company at approximately $965 billion, at the time overtaking OpenAI’s private valuation for the first time.³ Multiple reports have pointed to a target listing window around October 2026 on Nasdaq, though Anthropic has stated only that any offering will depend on market conditions and the outcome of SEC review, with no share price, share count, or date confirmed.
OpenAI submitted its own confidential filing days after Anthropic, having previously raised $122 billion in a March 2026 funding round that valued the company at approximately $852 billion.⁴ Earlier reporting had pointed to a fourth-quarter 2026 listing target. By late June 2026, however, reports indicated OpenAI was leaning toward pushing its public debut into 2027, following a volatile public debut for SpaceX and a broader slump in tech share prices.⁵
Neither company has confirmed a final listing date, share price, or valuation at listing, and both have said any offering remains contingent on market conditions and regulatory review. This is the backdrop against which OPENAIUSD and ANTHUSD’s private-market pricing currently sits, and it is also why both contracts include the IPO settlement provisions covered further down.
What are OPENAIUSD and ANTHUSD?
OPENAIUSD and ANTHUSD are Contracts for Difference (CFDs)⁶ that track the private market valuation of OpenAI and Anthropic respectively. A CFD is an agreement to exchange the difference in an instrument’s value between when a position opens and when it closes; it does not involve owning the underlying asset itself.
These two contracts have no expiration date. A position can be held indefinitely, subject to daily fees for as long as it stays open. That is a meaningful difference from a standard share CFD, where corporate actions and listing status are usually more predictable.
Both instruments are listed under Vantage’s Crypto Currency category on the platform rather than under Share CFDs or Indices. If you are searching for OPENAIUSD or ANTHUSD in the platform, that is the group to check first.
How pricing and trading specifications work
Prices for OPENAIUSD and ANTHUSD are derived from private market valuations and third-party data providers that track pre-IPO share transactions, rather than from a continuous public order book. That distinction matters for how these instruments behave day to day, and it is covered in more detail further down.
| Specification | OPENAIUSD | ANTHUSD |
| Contract size | 1 contract = 1 unit of underlying value | 1 contract = 1 unit of underlying value |
| Minimum / maximum trade size | 0.01 to 1,000 lots, in 0.01 increments | 0.01 to 1,000 lots, in 0.01 increments |
| Price display | 2 decimal places (e.g. 1651.54) | 2 decimal places |
| Trading hours | 24 hours a day, 7 days a week | 24 hours a day, 7 days a week |

The minimum and maximum trade sizes are the same as those used across other Vantage instruments, giving flexible position sizing whether a trader wants a small exploratory position or a larger one.
Ownership, equity, and what this product is not
This is worth restating plainly. Trading OPENAIUSD or ANTHUSD is not the same as buying actual shares in OpenAI or Anthropic. These are CFD derivatives. There is no ownership, no voting rights, and no claim to equity in either company that comes from holding a position.
OPENAIUSD and ANTHUSD are Vantage-listed instruments referencing the private market valuations of OpenAI and Anthropic. They are not issued, endorsed, or affiliated with either company, or with any of their affiliates.
The Tech-Driven Trader angle: what this product actually offers
Access to a private company’s valuation before it lists publicly is normally reserved for institutional investors, venture funds, or accredited investors taking part in funding rounds directly. OPENAIUSD and ANTHUSD give retail traders a way to get price exposure to that valuation without taking part in a funding round themselves.
That is the useful surface area, and it is worth being precise about where it ends. A private valuation is not the same as a continuously traded public price. It moves when new funding rounds, secondary transactions, or valuation updates from data providers occur, not in response to a public order book. Liquidity, volatility, and pricing behaviour will not necessarily resemble a listed share CFD, and there is no guarantee either company ever completes an IPO.
Common questions traders search for
Can retail investors buy OpenAI or Anthropic stock directly?
Not through a standard brokerage account. Both companies are privately held, and most direct routes, including secondary marketplaces and SPVs, require accredited investor status. A CFD referencing the private valuation, such as OPENAIUSD or ANTHUSD, is structured differently and does not carry that requirement, though it also does not involve ownership of the underlying shares.
How is trading OPENAIUSD or ANTHUSD different from pre-IPO share platforms?
Platforms that sell actual pre-IPO shares or SPV interests are transferring an ownership stake, which is why they are generally restricted to accredited investors and subject to each company’s transfer approval process. OPENAIUSD and ANTHUSD do not transfer shares or ownership at all; they are CFDs that reference the private valuation, settled in cash based on price movement rather than a transfer of equity.
What happens at IPO, or if there isn’t one
If OpenAI or Anthropic completes an IPO, Vantage may close all open positions at a reference price, delist the contract entirely, or transition it into a standard equity CFD. Advance notice will be provided before any of those changes take effect.
If neither company ever completes an IPO, the contracts remain tradable as they are today. Positions can continue to be held or traded as normal, the underlying valuation will continue to fluctuate based on private market activity, and daily fees will continue to apply for as long as a position stays open.
How to trade OPENAIUSD and ANTHUSD on Vantage Markets: Step by Step
1. Log in or open an account: Log in to an existing Vantage account, or complete registration and verification if opening a new one.
2. Find the instrument: Search for OPENAIUSD or ANTHUSD within the platform’s Crypto Currency category. Neither instrument is listed under Share CFDs.
3. Review the contract specifications: Check the contract size, minimum and maximum trade size, and price display before opening a position, since both instruments are structured differently to a standard equity CFD (see Table 1 above).
4. Choose a position size: Select a trade size between 0.01 and 1,000 lots, in increments of 0.01, based on the position size that fits your account.
5. Decide on position direction: Choose whether to open a long or short position according to your own view of the underlying valuation.
6. Set risk parameters: Many traders choose to add a Stop Loss at this stage to define an exit level in advance, given that pricing here is drawn from private valuation data rather than a continuous public order book.
7. Open the position: Confirm the trade to open the position. Daily fees begin accruing from this point for as long as the position stays open.
8. Monitor and manage: Since there is no expiration date, review open positions periodically, particularly around any news involving a potential IPO for either company, since Vantage may close, delist, or transition affected contracts at that stage.
9. Close the position: Close the position at any time, 24 hours a day, seven days a week.

Before you trade
Two things worth thinking through before opening a position in either instrument.
Because pricing is drawn from private market data rather than a continuous public order book, market participants often monitor these positions somewhat differently than a listed share CFD, watching for valuation updates rather than intraday order-book moves. Stop Loss tools remain available on both instruments for those who want a defined exit level.
Since these contracts carry daily holding fees for as long as a position stays open, position sizing relative to total account equity is worth reviewing before entry, particularly for a newly listed instrument with a different valuation mechanism to the rest of a trading account.
IMPORTANT RISK WARNING: This product is a high-risk derivative instrument. CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage. You should consider whether you understand how CFDs work and whether you can afford to take the high risk of losing your money. Past performance is not indicative of future results.
PRODUCT-SPECIFIC RISK: Pre-IPO Products track private company valuations which are inherently uncertain and illiquid. The price of these instruments may not reflect the actual value of the underlying company. You may sustain losses greater than your initial investment. This product is not suitable for all investors.
