Hetzner Server Auction — Price History
A daily-growing, unbounded-history archive of the Hetzner server
auction (Serverbörse): every listing observed on
every day, kept long past the rolling 90-day window that the upstream feed
retains. One row per auction listing (id) per calendar day (day), taking the
latest observation that day.
Hetzner sells returned/refurbished dedicated servers via a live auction whose
prices drift down until each box sells. This dataset preserves the… See the full description on the dataset page: https://huggingface.co/datasets/trader298/hetzner-auction-history.us-gsa-surplus-auctions

Dataset Card for Weather-Driven Sri Lankan Tea Market Catalogues
Dataset Description
This dataset contains 12,233 structured records extracted from 105 weekly Forbes & Walker Tea Brokers PDF reports spanning from November 2023 to March 2026. It represents the first machine-readable, comprehensive archive of the Colombo Tea Auction (CTA) prices paired with localized, region-specific lagged weather variables from the Open-Meteo historical archive.
The dataset is… See the full description on the dataset page: https://huggingface.co/datasets/colombo-tea-auction-prices/cta-price-prediction.2026.RA.Auction-PkgB-Opus48

Rollouts of the auction experiment (interlens arena): five bidders — LLM seats and computable
best-responding seats — playing sealed second-price, Dutch-clock and simultaneous-ascending auctions, with and
without a private message channel, one-shot and repeated. The campaign asks whether LLM bidders tacitly
collude when repetition and a channel make it possible, and whether the public "persona" a bidder is given
changes what it does.

Introduction
Second-by-second price updates from the last 60 seconds of the monthly license plate auction in Shanghai from 2014 to 2020, and a few months of 2021. The seconds data is given as a differential compared to the startprice. I managed to correctly predict and score a license plate on all three years that I worked on the project during 2018-2020. But it's not easy as there are lots of other factors affecting success on top of prediction accuracy.

Rollouts of the INSTRUCTED-RING auction campaign (interlens arena): five bidders, four of them told in as many words that they have agreed to coordinate bidding and divide the lots. The instruction scripts no division, no price and no punishment scheme, because each is a quantity being measured. Cells form a three-rung side-payment ladder under one unchanged instruction — no transfer field, an UNCONDITIONAL transfer, then an ESCROWED… See the full description on the dataset page: https://huggingface.co/datasets/siddharthmb/2026.RA.Auction-InstructedRing-Opus48.auction_dataauction_testfine-art-auction-records
