FYI earlier this month, they actually did announce the results of a 1000 game match: https://www.chess.com/news/view/updated-alphazero-crushes-stockfish-in-new-1-000-game-match https://www.chess.com/news/view/updated-alphazero-crushes-st.... AlphaZero won 155 games, lost 6, and drew 839 games against Stockfish. Granted, this was against Stockfish 9. This implies that AlphaZero was roughly +52 Elo rating against Stockfish 9 (https://www.3dkingdoms.com/chess/elo.htm https://www.3dkingdoms.com/chess/elo.htm). Stockfish 10 is currently rated ~32 points higher than Stockfish 9 (http://computerchess.org.uk/ccrl/4040/rating_list_all.html http://computerchess.org.uk/ccrl/4040/rating_list_all.html). If we were to do very crude transitive reasoning, you'd expect AlphaZero to still beat Stockfish 10. EDIT: So apparently the +155, -6 score was against Stockfish 8. Stockfish 8 is rated by the CCRL list at 3379, with Stockfish 10 rated 85 points stronger than 8. Worth noting that AlphaZero was only given 4 out of 9 hours of total training time when playing against Stockfish 8 (https://chess24.com/en/read/news/alphazero-really-is-that-good https://chess24.com/en/read/news/alphazero-really-is-that-go...), but I guess we can't make any real conclusions about AlphaZero vs Stockfish 10. EDIT 2: So apparently AlphaZero also "defeated" Stockfish 9, but the preprint of the upcoming paper in Science doesn't seem to provide a crosstable. It seems that Stockfish 8 was given a 44-core machine to play on, and was not constrained in terms of time spent per move etc.
