Show HN: Computable – Buy, sell, and redeem GPU for the exact weeks you want

#1

Post by yuansong98 »

Hey we are Computable. We spent years building trading infrastructure at Jump Trading and Coinbase. From that point of view, compute looks like energy markets before 2000: everything trades through private bilateral leases, there’s no visible price, and nothing can be resold. The same H100 rents at a 2x spread depending on who’s asking, and once you sign a 24-month lease, it can never change hands.

So we built a market for GPU nodes, sold by the calendar week. Here are three things you can do on it that you can’t do anywhere else:

- Buy exactly the weeks you need. Three nodes for the last two weeks of October means you pay for those two weeks and walk away when the run is done. You don't have to commit to 6-24 months, and there's no flexibility premium.

- Sell back what you don’t use. If your plans change, unused weeks turn back into cash: we keep a market quote posted on every position, so there’s always a price to hit.

- Buy (or sell) the future. Lock January in July at a price you set, so the cost of a future run is known before another 40% H100 rate jump makes it not.

The first auction is live now at https://market.getcomputable.com: a block of nodes, August through the end of January. Bidding closes July 31. The bids are sealed. You bid how many nodes, which weeks, and your price. Every clearing price gets published after settlement, because nobody knows what a GPU week is worth and we want the prints to exist in public.

Happy to go deep in the comments on anything, including the clearing mechanism, which is a packing problem and was fun to design!

Interesting approach. How do you ensure liquidity if buyers and sellers want different weeks? Is there a market maker, or is everything matched through the auction?

I imagine they’re building the supply side as well, where you can bid your fixed GPU. My question with this stuff is how do I know my data is secure on these for-rent boxes? What steps are taken to sanitize the GPU between runs etc.

Didn't sfcompute launch with a vision of something like this and then cancel it because CFTC decided it was running an unregulated futures exchange? How are you getting around regulatory issues like this?

Good question. this is something we built around from day one. Users pay 100% up front for specific nodes on the exact weeks they want. No leverage, no margin, no cash settlement. This is honestly not that much different from you booking a hotel.

What does "no cash settlement" mean? If I sell a reservation, do I not get cash?
