Ondo Perps now accepts its OpenAI private market note OPAIPon as collateral, enabling an OpenAI basis trade

What Ondo Perps switched on

Ondo Perps announced on 28 October 2026 that OPAIPon, its tokenized OpenAI Private Market Note, can now be posted as collateral. Until now the note traded only as a fully funded spot asset on the platform's order book. From this week a trader can hold it and also count it as margin for perpetual futures, the contracts with no expiry date that Ondo Perps offers on crypto, stocks, indices and commodities.

Ondo Perps calls this the first private-market asset to back perps positions on the platform. It joins the tokenized public-market assets that were already accepted, which the announcement lists as CRCLon, SPCXon, SPYon, QQQon, GLDon and more. As our earlier coverage explained, OPAIPon is a note, not OpenAI shares: each note references one share of OpenAI common stock and pays out the per-share value realized at a qualifying liquidity event, and it is issued by PM Issuer Co (BVI) Limited.

The OpenAI basis trade in one account

The use case Ondo highlights is an OpenAI basis trade in one account. The trader buys OPAIPon on the spot order book, posts it as collateral and opens a short position on the OPENAI pre-IPO perp. If the perp trades at a premium to the note, the trade aims to profit as that gap narrows, whether spot rises, the perp falls or both move. Ondo adds that funding payments can add to the result when funding rates are positive.

The capital point is simple. On a venue that accepts only stablecoin margin, the trader would need money for the note plus separate stablecoins to back the short. With the note accepted as collateral, the same holding counts toward the margin for the short. Ondo also pitches this as a hedge: an OPAIPon holder can short a sized amount of the perp to reduce exposure to OpenAI price moves without selling the note, or use the note as margin for unrelated trades on other markets.

The limits Ondo spells out

Ondo's own fine print matters here. The note and the OPENAI perp have different units, terms and pricing, their prices can diverge and convergence is not guaranteed. OPAIPon collateral has a 65% loan-to-value threshold for Auto-Exchange, a mechanism that can sell the collateral without closing the short, which would leave the trader with an unhedged short. Terms and conditions apply, and earlier Ondo Perps material says the platform is not available in the US, Canada or Panama.

Our take

This is the third OpenAI step on Ondo Perps this month, after the OPAIPon spot listing and the 3x pre-IPO OpenAI perp. Accepting the note as margin is what links the two, so the basis trade Ondo described in September for tokenized stocks now works on private-market exposure too. The upside is capital efficiency; the risk is that the pricing gap is not guaranteed to close before OpenAI has any liquidity event, and an Auto-Exchange sale at the 65% threshold breaks the hedge. Treat it as a tool for experienced perps traders, not as a guaranteed spread.
