The range this is computed against
The classic recreational flatting range — a player who "likes to see a flop". Any pocket pair, any suited ace, king, queen or jack, every playable suited gapper, all the offsuit aces and a stack of offsuit broadways. Around half of all hands, and almost none of them are folded before the flop.
calling station — 670 combos, 50.5% of all starting hands: AA, KK, QQ, JJ, TT, 99, 88, 77, 66, 55, 44, 33, 22, AKs, AQs, AJs, ATs, A9s, A8s, A7s, A6s, A5s, A4s, A3s, A2s, KQs, KJs, KTs, K9s, K8s, K7s, K6s, K5s, K4s, K3s, K2s, QJs, QTs, Q9s, Q8s, Q7s, Q6s, Q5s, Q4s, Q3s, Q2s, JTs, J9s, J8s, J7s, J6s, J5s, J4s, J3s, J2s, T9s, T8s, T7s, T6s, T5s, 98s, 97s, 96s, 95s, 87s, 86s, 85s, 84s, 76s, 75s, 74s, 65s, 64s, 63s, 54s, 53s, 43s, AKo, AQo, AJo, ATo, A9o, A8o, A7o, A6o, A5o, A4o, A3o, A2o, KQo, KJo, KTo, K9o, K8o, K7o, QJo, QTo, Q9o, Q8o, JTo, J9o, J8o, T9o, T8o, 98o

Against a loose-passive calling range (670 combos, 50.5% of all hands), AK runs at 64.5%. It wins 63.0% of runouts outright, loses 34.1% and splits the remaining 3.0%. Your own two cards remove 86 of those combos before the flop is even dealt — a blocker effect this number already accounts for, because every combo containing one of your exact cards is stripped out of the range first. You are ahead of 510 of the 584 combos you can still be facing (87%), which is what a 64.5% number actually looks like hand by hand.
Where does the range come from? The classic recreational flatting range — a player who "likes to see a flop". Any pocket pair, any suited ace, king, queen or jack, every playable suited gapper, all the offsuit aces and a stack of offsuit broadways. Around half of all hands, and almost none of them are folded before the flop. Broken down hand by hand, AK does worst against AA (8.2%), KK (31.1%) and TT (43.8%) and best against K9o (76.4%), K8o (76.1%) and K7o (75.9%). Across the whole range AK's equity swings from 8.2% at the bottom to 76.4% at the top — the single 64.5% headline is the combo-weighted average of all of it.
A loose-passive calling range is the most profitable opponent in poker and 64.5% is why: AK is ahead of the average call, but a station's range is wide enough that you will get outdrawn often — bet for value and stop bluffing.
AK vs calling station FAQ

Which hands in a loose-passive calling range beat AK?

What hands are in a loose-passive calling range?
105 hand classes and 670 combos — 50.5% of the 1,326 possible starting hands. By combo count it is 12% pocket pairs (13 pairs, 78 combos), 38% suited hands (64 classes, 256 combos) and 50% offsuit hands (28 classes, 336 combos). That shape is why AK runs at 64.5% against it rather than against a random hand.
Does AK do better against a wider or a tighter range?
Wider, almost always. AK has 64.5% equity against a loose-passive calling range (50.5% of hands) but 46.1% against a 4-betting range (3.2%). Equity against a range is mostly a question of how many weak hands the range still contains — which is why the same holding can be a monster against a button open and a fold against a 4-bet.
