Lium’s October GPU Billings Hit $2.32 Million, Up 74%

Lium (Subnet 51), Bittensor’s decentralised GPU rental marketplace, reported that renters spent $2.32 million on GPU time in October, up 74% on the 31 days before.

Rentals rose 66% to 25,311, and the number of billed customers more than doubled, up 122% to 2,437. The figures were shared by the Lium team in the project’s Discord channel.

The month got stronger as it went. Daily spend doubled through October, with the seven-day average climbing from about $49,000 a day in the first week to $100,000 a day in the last.

Existing customers also spent more. Those billed in September spent 123% of their September total in October, a sign that growth is coming from deeper usage as well as new sign-ups.

Blackwell carries the bill

Frontier hardware is doing most of the earning. B300, B200, RTX PRO 6000 and RTX 5090 GPUs, all from Nvidia’s Blackwell generation, took 63% of October GPU spend, and the B300 alone brought in $950,000.

Lium’s live network stats show why. The B300 SXM6 is now the marketplace’s second most-listed GPU after the RTX 5090, with 346 units listed in the main variant and 49 more in a second variant.

B300s rented over the past 30 days went for a median of $8.00 an hour, against $0.50 for an RTX 5090, and Lium estimates a rented B300 can earn its provider about $4,845 a month. On 22 October, Lium cited 225 B300s in a fleet it valued at more than $30 million; the stats page now lists 395.

Agents are the main customer channel

74.6% of October rentals started outside the web app, through the CLI, API, MCP server or Python SDK. That is up from 68.7% in Lium’s previous monthly review, published 10 October.

Lium has built its product around that mechanism, and its homepage pitches “give your AI agent a GPU in one command”, with per-second billing and pods that shut themselves down on a timer or a budget the user sets.

Month on month: from $964K to $2.32M

Lium’s monthly reviews show the progression:

Period	Billed to renters	Growth	Customers	Rentals
Prior month (implied)	~$709K
Aug 10 – Sep 9	$964K	+36%	1,187	7,697
Month to Oct 9	$1.40M	+45%	1,379	17,497
October (Oct 1–31)	$2.32M	+74%*	2,437	25,311
Last 30 days to Nov 8	$2.57M	rolling	—	28,346

*October growth is against the 31 days before (roughly calendar September), not against the $1.40M review window.

The momentum has carried into November. As of 8 November, lium.io/stats shows $2.57 million billed to renters over the past 30 days, 1.08 million GPU-hours served and 28,346 rentals. Annualised, that is a run-rate of about $31 million.

The supply side

The stats page also shows how the marketplace is filling up. 2,141 GPUs across 36 models are listed by 122 providers in 39 countries, with the United States hosting 41% of listed nodes, followed by Ukraine, Finland and Romania.

1,344 of those GPUs (63%) were rented at the time of the snapshot, and utilisation over the past 30 days was 76%. Reliability scores are high, the median listed node scores 98.6, and 88% score 95 or more.

Providers set their own prices. Lium advertises that they keep 95% of rental revenue, paid daily on-chain, plus SN51 emissions that reward GPUs that are idle but available.

Revenue back into SN51

For alpha holders, the revenue is important because Lium routes it back to the token. The subnet used marketplace revenue to buy back and burn nearly $2.7 million of SN51 alpha across five buybacks between April and September, and the team has since moved to daily automated burns.

Lium’s growth is becoming increasingly evident, with more paying customers, higher spending from existing users, and rising demand for high-performance Blackwell GPUs. With nearly three-quarters of rentals now initiated through software integrations, the marketplace is also establishing itself as infrastructure for automated AI workloads.
