Not really: they have been broadly flat. As of Nov 2, 2026, adjusted for trim and model year, Porsche 991 prices over the last 12 months were broadly flat (-3% a year) (377 online-auction sales); over the last 3 months the mix-adjusted median moved 0% against the 3 months before (within normal sample noise), with the raw median at $112,250 against $110,991, and our market signal reads Hold (no clear move).
Within the 991, rising fastest is the Porsche 991 GT2 RS (+68%/yr); easing most is the Porsche 991 GTS (-9%/yr).
Quarter by quarter (online auctions): the median was $115,000 in Q3 2026 (117 sales), against $115,000 in Q2 2026 (135 sales), a 0% change. Quarterly medians move with the mix of cars sold, which is why the headline answer uses the mix-adjusted figures.

How we measure the trend
The 12-month trend is a robust (Theil-Sen) slope of sold prices after removing each sale's trim and model-year effect, so a run of pricier cars does not look like a rising market. The 3-month change compares the mix-adjusted median of the last 3 months with the 3 months before, and the Buy / Hold / Sell signal needs at least 15 sales in each window and a move of 8% or more. These are the same numbers as the market signal on the Porsche 991 page. It describes recent auction results; it is not a forecast or financial advice. Methodology.
