US neocloud selling on-demand and reserved bare-metal NVIDIA HGX H100 clusters from $1.99/hr; acquired TensorDock (2025) and merged with Lightning AI (Jan 2026).
A real, competitively priced, self-serve GPU marketplace, but it is a Singapore-based broker of other providers' capacity with non-refundable credits, a $10,000 refund floor, and no SLA of its own.

Spheron runs a decentralized GPU marketplace operated by Beta360 Pte Ltd (Singapore) [1] with published rates for consumer and datacenter GPUs. Three red flags are confirmed verbatim from the terms: a $10,000 refund floor with sole-discretion approval [2], a 99.9% marketing SLA that contradicts the 99.5% provider-determined terms [3], and prices that can change on running instances [4].
GPU compute from a live catalog - rates refresh every five minutes from inventory [4]. Published on-demand rates: H100 $2.98/hr, A100 $1.43/hr, B200 $8.63/hr, B300 $12.42/hr [4]. New bare-metal nodes (8x HGX B300 in a Tier III EU data center) are sold out with a waitlist [5]. Pre-order listings exist for upcoming R100 Rubin hardware [4]. Billing runs in credits/USD through Beta360 [1]. KYC: not documented in the terms [1].
The terms bind you to Beta360 Pte Ltd (Singapore, UEN 202107371K) [1]. Refunds only above a $10,000 aggregate threshold, "review and approval at the sole and absolute discretion of the Company" [2]. The homepage's "99.9% Uptime SLA" contradicts the terms' "up to 99.5%, subject to the specific Provider selected" - and the terms explicitly disclaim any guarantee for Dedicated Instances [3]. Price changes may apply to already-running instances with no rate lock [4]. The legacy SPON token trades at well under a cent with a market cap of roughly one hundred fifty thousand dollars [5] - not used for compute billing - it exists as a legacy artifact from an earlier era of the project.
The GPU rental page publishes a live catalog with the caveat "Rates read from live inventory and refresh every five minutes" [5]. The terms are server-readable and carry all three red flags verbatim [1]. What stays unverifiable: actual provider performance behind the 99.5% ceiling, the identity of individual GPU providers behind the marketplace, and the real utilization of the listed capacity [5].
No reliability incidents, fraud patterns or community complaints surfaced [6]. The three red flags (refund floor, SLA contradiction, price changes on running instances) are structural - they are in the terms, not community complaints [1][2][3]. Google News coverage is limited to price-tracker pages and a Messari overview [6]. No exit or insolvency events surfaced [6].

Current bookable floor is about 78 cents per hour for RTX 6000 Ada spot [5]. Published on-demand: H100 $2.98, A100 $1.43, B200 $8.63, B300 $12.42 [5]. Prices move constantly (as the terms warn) - the snapshot is point-in-time [5]. SPON legacy token: $0.00066733, market cap roughly one hundred fifty thousand dollars [5]. KYC: undocumented [1]. Credits non-refundable below $10,000 [2].
Spheron has a real marketplace with a named Singapore entity and live inventory [1] - shadowed by three consumer-unfriendly terms (refund floor, SLA contradiction, price changes on running instances) that are all in the operator's own documents [2][3][4]. For short bursts with small balances, the terms may be tolerable; for long-running deployments, the no-rate-lock clause is a real financial risk [4].

The docs.spheron.ai homepage separately advertises H100/A100/B200 'from $0.72/hr' - a conflicting headline that is not reconciled on the pricing table. Rates are provider-set and can change on running instances (Terms 5.9). |

A real, operating provider can still lose you money: with a contract you own no hardware, revenue follows coin price and difficulty, and most published contracts are priced so the seller comes out ahead. "Legit" means the operator exists and pays what its terms promise - not that the deal is profitable. 9 dated sources back this page; they are listed under sources.
Same category, scored on the same criteria - so the comparison stays honest. Compare only in the same unit, and read the minimum, KYC and proof columns before switching.
