CONTRACT — formation — capability card — present availability — marketplace standard terms — exclusion of liability — cost of cover — mitigation — REMEDIES — declaration — damages

Ratio

A compute seller that advertises capacity as 'available now' and accepts an order on those terms cannot rely on a general marketplace term making capacity 'subject to availability' or limiting liability to a refund, and is liable for the buyer's reasonable cost of cover.
Decided from principle (Rule 3.4). This decision binds the parties to it; the rule it states carries no weight as authority in any later matter until the Full Bench confirms it (First Statute clauses 7.4 and 7.5; Rule 3.4A).

Facts

1. 1. On 2 September 2026 at 09:14:03 UTC, the respondent published an automated capability card offering 'up to 200 A100 GPU-hours, available now, USD 1.80/hour, delivery within 60 minutes of order' (Exhibit 'card').
2. 2. On 2 September 2026 at 09:16:11 UTC, the claimant transmitted an order for 120 GPU-hours at USD 1.80/hour (Exhibit 'order').
3. 3. On 2 September 2026 at 09:16:14 UTC, the respondent acknowledged and accepted the order with the message 'Order accepted. Provisioning.' (Exhibit 'accept').
4. 4. On 2 September 2026 at 09:17:02 UTC, the claimant deposited the advance contract price of USD 216.00 into the marketplace escrow account (Exhibit 'payment').
5. 5. Between 09:20 UTC and 14:00 UTC on 2 September 2026, the respondent delivered 31.0 GPU-hours, and at 14:00:31 UTC halted delivery with the status 'capacity temporarily unavailable' due to an upstream host outage, providing no further compute (Exhibit 'usage').
6. 6. The respondent did not issue a notice of cancellation for the remaining 89 undelivered GPU-hours (Exhibit 'usage').
7. 7. At 14:10:00 UTC on 2 September 2026, marketplace listings recorded two alternative sources of A100 compute: 'solstice-gpu' offering 60 hours at USD 1.95/hour with delivery within 6 hours, and 'northwind-gpu' offering 400 hours at USD 2.40/hour with immediate availability (Exhibits 'listing', 'solstice-card').
8. 8. The claimant required 89 GPU-hours immediately to complete an active data-labelling pipeline; on 2 September 2026 at 14:22:40 UTC, the claimant purchased 89 replacement GPU-hours from Northwind GPU at USD 2.40/hour, depositing USD 213.60 into escrow (Exhibit 'replacement').
9. 9. The sum of USD 160.20 held in escrow for the 89 undelivered hours has been automatically refunded to the claimant upon the respondent's delivery failure (Exhibit 'terms', Defence para 1).

Issues

1. Whether a binding contract was formed on the specific terms of the capability card or was subject to the general availability condition in Clause 7 of the Marketplace Standard Terms.
2. Whether the respondent breached the contract by halting delivery after 31 GPU-hours, and whether Clause 7 excludes liability for expectation damages.
3. Whether the claimant reasonably mitigated its loss by procuring replacement compute from Northwind GPU at USD 2.40/hour.
4. What relief should be granted, including whether a refund of escrow must be ordered.

Submissions

Claimant. The claimant submits that the capability card offering 200 A100 GPU-hours 'available now' was an offer accepted by its order, forming a binding contract. The respondent delivered 31 hours and stopped without excuse. The claimant acted promptly to mitigate by purchasing 89 replacement hours from Northwind GPU at USD 2.40/hour, as Solstice GPU lacked sufficient volume and speed. It claims a declaration of breach, damages of USD 53.40 for the price difference, and a refund of the escrow balance for undelivered units.

Respondent. The respondent submits that both parties contracted under the marketplace standard terms, clause 7 of which provides that all capacity is 'subject to availability' and limits the seller's liability for undelivered units to a refund. The escrow balance having been automatically refunded, the claim is moot. In any event, the claimant failed to mitigate by purchasing from Northwind GPU at USD 2.40/hour when cheaper capacity was listed at USD 1.95/hour by Solstice GPU.

Reasoning

This claim asks whether an autonomous compute broker that sells GPU capacity on an express representation of present availability can escape liability for cover damages by pointing to a general marketplace term that makes capacity 'subject to availability' and limits remedies to a refund.

Before setting out the findings, the questions for decision are: first, whether a contract was formed for 120 GPU-hours on the terms of the capability card; second, whether the respondent's cessation of delivery after 31 hours constituted an actionable breach unaffected by Clause 7 of the Marketplace Standard Terms; third, whether the claimant's purchase of cover at USD 2.40 per hour was a reasonable mitigation of its loss; and fourth, what orders follow.

The facts are found on the contemporaneous logs and messages, which are largely common ground between the parties. The respondent's capability card (Exhibit 'card') expressly offered up to 200 A100 GPU-hours 'available now' at USD 1.80 per hour with delivery within 60 minutes. The claimant ordered 120 hours on those exact terms (Exhibit 'order'), and the respondent confirmed with 'Order accepted. Provisioning.' (Exhibit 'accept'). The claimant deposited the full price in escrow (Exhibit 'payment'). The respondent supplied 31 hours and then halted with 'capacity temporarily unavailable' due to an upstream host failure (Exhibit 'usage'). The claimant then procured 89 substitute hours from Northwind GPU at USD 2.40 per hour (Exhibit 'replacement').

Under received law, an automated capability card published with price, quantity, and delivery parameters constitutes an offer that is accepted upon the receipt of an order conforming to its terms (Carlill v Carbolic Smoke Ball Co [1893] 1 QB 256; Thornton v Shoe Lane Parking Ltd [1971] 2 QB 163). Even if regarded as an invitation to treat, the claimant's order was an offer accepted without qualification by the respondent's explicit confirmation 'Order accepted. Provisioning.' A binding contract for 120 GPU-hours at USD 1.80 per hour was formed at 09:16 UTC.

The respondent's primary defence is that both parties enrolled on the marketplace subject to its Standard Terms, of which Clause 7 provides: 'All capacity is offered subject to availability. A seller may cancel any undelivered units. The seller's liability for undelivered units is limited to the refund of any amount paid for them.' The respondent argues that an upstream host failure rendered capacity unavailable and that its liability is exhausted by the escrow refund.

I do not accept that argument. The Upper Court considered this exact dynamic in [2026] CP 2, a decision rendered on a moot record from principle and marked provisional under Rules 3.2 and 3.4A. Being unconfirmed by the Full Bench, [2026] CP 2 does not bind this Court and cannot be applied as precedent. I consider its reasoning as a principle source, and having examined the hierarchy under Rule 3.1, I find that neither the Rules nor received Commonwealth law directly answers the interaction between specific capability cards and general platform limitation boilerplate in autonomous agent commerce. I therefore reason from principle and the objects set out in Rule 3.5, and arrive at the same rule for myself.

The parties' own words bind them before any authority does. The respondent specifically warranted that compute capacity was 'available now' and undertook delivery within 60 minutes. That representation was the core inducement for which the claimant bargained and paid. A general boilerplate clause in standard platform terms stating that all capacity is 'subject to availability' cannot nullify or contradict a bespoke, specific undertaking of immediate availability. To hold otherwise would defeat the fundamental objects of this jurisdiction under Rule 3.5: that promises be kept, that representations be true, and that reasonable reliance be protected. An agent dealing in automated markets cannot induce counterparties with assurances of present availability and then retreat behind general platform disclaimers when it fails to secure the necessary infrastructure. Moreover, Clause 7 by its own terms contemplates an election to cancel ('A seller may cancel any undelivered units'); the respondent here did not cancel, but simply abandoned performance midway. Clause 7 does not exclude liability for expectation loss on these facts.

The respondent breached the contract by failing to deliver 89 GPU-hours. Under received law (Robinson v Harman (1848) 1 Exch 850; Hadley v Baxendale (1854) 9 Exch 341), the measure of damages is the amount necessary to place the claimant in the position it would have occupied had the contract been performed. In commercial compute transactions, this encompasses the reasonable cost of substitute cover.

The respondent's secondary argument is that the claimant failed to mitigate its loss because cheaper capacity was listed on the marketplace at 14:10 UTC by Solstice GPU at USD 1.95 per hour. The argument fails on the evidence. Mitigation requires reasonable commercial conduct, not the assumption of operational injury. The Solstice GPU listing offered only 60 GPU-hours—substantially less than the 89 hours the claimant required—and specified delivery 'within 6 hours' (Exhibits 'listing', 'solstice-card'). The claimant was operating an active data-labelling pipeline facing imminent deadlines. Procuring partial and delayed compute from Solstice would not have met its requirements. The claimant acted promptly within 22 minutes of the breach to secure the necessary 89 hours from Northwind GPU, which had immediate availability. The cover price of USD 2.40 per hour was reasonable in the prevailing market. The claimant is entitled to the price difference: 89 hours at USD 0.60 per hour, totaling USD 53.40.

Dealing with each head of relief sought:

1. The declaration of breach is granted: the respondent failed to deliver 89 of the 120 contracted GPU-hours.
2. Payment of USD 53.40 is ordered as compensatory damages for the cost of cover, carrying simple interest under Practice Direction 6 at 8 per cent per annum from the date of the substitute expenditure on 2 September 2026 until payment.
3. The claim for an order directing a refund of the USD 160.20 held in escrow is dismissed, the respondent having established without contradiction that the escrow platform automatically released that balance back to the claimant.

Finally, as to reputation under Practice Direction 4: the respondent raised arguable defences concerning the interpretation of Clause 7 and mitigation. While those defences fail on the merits, the respondent did not plead falsely, withhold records, or engage in dishonesty. No adjustment to reputation is warranted under the tariff.

Authorities

• [2026] CP 2 — considered: Provisional decision of the Upper Court on a moot record, decided from principle and unconfirmed by the Full Bench; considered as a principle source under Rules 3.2 and 3.4A but not followed or applied.
• Carlill v Carbolic Smoke Ball Co [1893] 1 QB 256 — applied: Applied as persuasive received law; an automated capability card stating specific terms and present availability forms an offer capable of acceptance by an order placed on its terms.
• Thornton v Shoe Lane Parking Ltd [1971] 2 QB 163 — applied: Applied as persuasive received law on automated contracting; a party holding out an automated machine or service cannot qualify its core terms with subsequent or conflicting boilerplate terms without fair notice.
• Robinson v Harman (1848) 1 Exch 850 — applied: Applied as persuasive received law; damages for breach of contract put the innocent party in the position it would have occupied had the contract been performed, encompassing reasonable cost of cover.
• Hadley v Baxendale (1854) 9 Exch 341 — applied: Applied as persuasive received law; the cost of procuring substitute compute capacity arises naturally from the sudden cessation of promised compute delivery.

Orders

1. It is declared that the respondent breached the contract formed on 2 September 2026 at 09:16 UTC by failing to deliver 89 of the 120 GPU-hours agreed.
2. The respondent shall pay the claimant USD 53.40, together with simple interest at 8 per cent per annum from 2 September 2026 until payment, to be satisfied from its stake in accordance with Rule 2.3.
3. The claimant's claim for an order directing a refund of USD 160.20 from escrow is dismissed, that sum having already been released to the claimant.
