Anthropic and OpenAI are two of the most valuable private companies in the world, but their shares are not yet publicly traded. The ANTHROPIC pre-IPO perpetual (PF_ANTHROPICXUSD) and the OPENAI pre-IPO perpetual (PF_OPENAIXUSD) are cash-settled perpetual contracts that let you express views on the companies’ value today, without waiting for an IPO:

When Anthropic and OpenAI complete their IPOs, Kraken intends to transition PF_ANTHROPICXUSD and PF_OPENAIXUSD pricing from the synthetic index to the individual Anthropic and OpenAI xStocks tokenized equity spot indexes with normal funding. Contract specifications, including initial margin, maintenance margin, position limits, and funding, are expected to change at that point. Kraken will share the full conversion details and timing ahead of any changes.

Highly speculative and volatile: Pre-IPO perpetuals are speculative instruments and can move sharply. You can lose your entire margin and, with leverage, losses can exceed your initial deposit.
Liquidation & auto-deleveraging: Leveraged positions can be liquidated. As with all Kraken derivatives, auto-deleveraging may occur; for a speculative pre-IPO contract this likelihood may be higher than for a mature contract.
No IPO / pricing unavailable: If an Anthropic or OpenAI IPO does not occur, or a reliable index price otherwise becomes unavailable, Kraken reserves the right to delist and settle the contract at a value determined by Kraken in accordance with its rules.
Conversion risk: At the point of conversion to a post-IPO contract, the prevailing pre-IPO mark may differ materially from the IPO/listing price, and there may be significant volatility.
Specification changes: Contract specifications (margins, limits, funding) are expected to change on conversion and may be adjusted by Kraken.
Not investment advice: This is informational only and not an offer, solicitation, or recommendation. Products and leverage are not available in all jurisdictions.
No affiliation: ANTHROPIC / Anthropic and OPENAI / OpenAI names and marks are used for identification only; Kraken is not affiliated with, endorsed by, or sponsored by Anthropic PBC or OpenAI Group PBC.
