Used RTX 4090 market prices
eBay US · item + shipping, before tax
Daily asking prices
September 13–November 2, 2026 · 51 daily observationsThese are asking prices, not sale prices. Buyers often pay less, because many eBay sellers accept offers.
How we calculate these prices
Every day we collect available eBay US listings for the RTX 4090, filter out wrong products and unusable offers, keep used cards only, and add any explicitly quoted shipping to the item price. Tax is excluded.
Listings whose shipping is calculated at checkout are left out, because we cannot know their delivered price. They usually ask a little less than the listings we count.
The green line counts each seller once. It is the median of the sellers' own median prices, so a seller with twenty listings cannot pull it. The blue band covers the middle 50% of individual listing prices. It shows the spread of asking prices, not a confidence interval. A day is shown only with at least five listings from three sellers.
The same listing can appear on many days, so day-to-day changes often reflect which cards are listed rather than a market move. Gaps mark days that were not collected, had too few listings, or are held for review. New-card coverage is too small to report.
