no sales teams, no estimates, no curated prices. individuals plug a rig into the wall, name a price, and the market clears. this is the tape: live p2p gpu rentals, cross-market arbitrage, the retail cloud index — so you can see the landlord tax — the peer grid, and hashpower. every number on this page was pulled from a live public api within the last sixty seconds.

“The best way to predict the future is to invent it.”

value is not the cheapest card. it is the most math per dollar from a host that stays up.

the fit — what your money runs open-weights models vs the live tape · weights × quant + 2gb kv · decode is memory-bound: ~tok/s ≈ 0.75 × bandwidth ÷ active weights · multi-gpu scaled n^0.7 for the parallelism tax · batch 1 · the only ~estimates on this page, labeled as such

“Talk is cheap. Show me the code.”

— linus torvalds · linux-kernel mailing list, 2000

deepseek-r1, the whole 671B of it, rents at $15.00/hr in q4 right now (2× B300) — roughly $9.18 per million tokens, single stream. the frontier api guys charge rent on open weights; the open market is one row up.

the arb — same silicon, five live markets vast.ai · runpod · akash on-chain · clore · tensordock · live · sorted by spread

“There is nothing new in Wall Street. There can't be, because speculation is as old as the hills.”

— jesse livermore · reminiscences of a stock operator, 1923

clore's floor is bottom-tier hosts — some carry minimum-rental terms, and the vetting is thinner than vast's verified tier. that gap is not an error, it is the price of trust. the same card clears at three prices an api call apart; wide spreads are the market telling you it is still young.

the clouds — the retail market, live 19 clouds · 272 skus · via shadeform's keyless api · cheapest in-stock sku per model · * = listed price, no live stock · p2p saves = tape vs that sku

“The network is the computer.”

— john gage · sun microsystems, 1984

green is money the landlord would have taken. the p2p tape clears below the cheapest retail cloud on 9 of 10 matched models — before you even negotiate.

the hyperscaler shelf aws · azure · gcp live list prices, us-east · on-demand linux · * = cloud listed price, no live stock

this is the whole argument in one table: the same h100 rents for $6.88 on aws and $1.87 on the tape, right now. the hyperscalers are not selling compute, they are selling compliance — if you don't need it, the market is right there.

the machine — rent vs own live rate · your price · drag the hours

“We are what we repeatedly do. Excellence, then, is not an act, but a habit.”

— will durant, summarizing aristotle · 1926

the rate is live, the price is yours, the math is arithmetic. nothing on this page is estimated.

the buy side — own the silicon, in stock only newegg video-cards category, parsed live · add-to-cart button = actually in stock · 24h = retail median move · peer listings from r/hardwareswap + r/homelabsales · 30m refresh

“Cram more components onto integrated circuits.”

— gordon moore · electronics, 1965

break-even is months of 24/7 renting that equal the purchase price — right now a 5090 pays for itself in 23.7 months of round-the-clock work. need it for a weekend? rent. need it forever? the table above is your shopping list.

the swap meet — latest peer listings, priced r/hardwareswap + r/homelabsales · active [H] posts with an asking price · newest first

these are people, not storefronts. the price is whatever they typed — verify the card, pay with protection.

the other side — sell your gpu live tape rate × 70% utilization − power at $0.12/kwh · mining floor from whattomine, live · stated assumptions, real rates

“If you don't find a way to make money while you sleep, you will work until you die.”

— warren buffett · attributed

the mining floor is the alternative bid: if renting pays less than mining, mine. right now the tape outbids mining on all 11 consumer cards tracked — that gap is the p2p premium. plug in: host on vast · host on nuza.

the grid — the peer network, live who is actually plugged in, right now

“The value of a network is proportional to the square of the number of connected users.”

— bob metcalfe · metcalfe's law, 1980

this is what a market looks like without a landlord: rigs in vietnam, korea, ontario and oregon clearing against each other while you sleep.

hashpower — the other p2p compute market nicehash public stats · rigs selling hashrate, right now · 5m refresh

“If you don't believe me or don't get it, I don't have time to try to convince you, sorry.”

— satoshi nakamoto · bitcointalk, 2010

374,843 rigs sell hashpower by the terahash while you read this. compute has been p2p since 2009 — the ai market is just catching up.

the wires — every feed, its pulse cache age per upstream source · live = within its refresh window · the page never blocks on a dead wire, it serves the last good read

an index is only as honest as its wires. this is ours, in the open — when a source dies you'll see it here before you distrust a number.

why gpudex?

every price on this page is a person. a rig in a spare bedroom in vietnam, a basement in ontario, a datacenter cage someone rents by the month. no bundling, no enterprise agreements, no "contact sales" — plug in, name a price, clear. the people below built the machine this market trades in. this page is just the arithmetic, in their honor.
