The Euronext futures exchange launched the Paris home price futures contracts (symbol PRE) on Thursday June 6th. The Sept 2019 contract has been the only quoted contract (at about a 1% bid/ask spread) and it doesn't appear that there have been any trades.
I've posted a document to the Resources section (on the lower left under International headline) to address expected FAQs about this contract. The document contains links to: contract specs, index calculation, trading volume and open interest, and a list of market makers.
Meantime, here's a graph of the Paris home price index and the Case Shiller 10-city index (with both axes on the same scale). Paris didn't experience the sell-off US home prices did from 2008-12, but instead had a slow period of sell-off during 2013-2015. Since 2017 the YOY change in the Paris home price index has generally outpaced gains in the US, and the two markets appear to be more correlated.
Feel free to contact me if you have any questions or insights on either the Paris index, or the Euronext futures.
