October's trending boards moved for two reasons: Halloween, and everything that was not Halloween. Horror movies surged on IMDb, Halloween hashtags topped TikTok, and "fall nails" led Pinterest. Meanwhile shopping apps climbed the App Store, business podcasts rose on Spotify, and a college hashtag climbed TikTok faster than anything else on the board. These are the exact rank changes, board by board, measured between October 3 and November 2.
TikTok: #cornell7 was the month's strangest riser
cornell7 shot up 116 places to #69 across the 30-day window, the steepest climb recorded on any TikTok board. #cornelluniversity rose 68 ranks to #47 alongside it. The timing lines up with a Cornell announcement on October 29, saying state police would take over sexual assault investigations on campus, which 11 outlets including Reuters covered; the data does not prove the news caused the hashtag surge (Cornell's announcement). Seasonal entries filled the rest of the top risers: #costume climbed 66 ranks to #131, and #tiktokshopblackfriday climbed 50 ranks to #100, TikTok's earliest signal that holiday shopping content had begun. The board's overall leader for the month was #halloween, with #nfl and #football in the top five.Wikipedia: two films moved, one actress followed
Obsession (2025 film) rose 131 ranks to #22 on Wikipedia's 30-day board, the largest climb measured on any board this month. You Can See Everything, the film about Elizabeth Holmes, rose 127 ranks to #19, and Holmes herself rose 75 ranks to #10. Horror held its ground behind them: MobLand climbed 90 ranks to #89. Wikipedia traffic is research traffic, so the pattern reads clearly. October's films sent people to look things up, and the month's biggest Wikipedia entries were all pages about movies and shows, not events.
IMDb: the 1990s are back every October
Scream (1996) climbed 70 ranks to #23 on IMDb's MOVIEmeter over two weeks, the largest film climb in the set. The Nightmare Before Christmas (1993) rose 65 ranks to #16, Casper (1995) rose 51 ranks to #41, and Hocus Pocus (1993) gained 45 ranks to land at #5. Hereditary (2018) gained 47 ranks to #52, the lone 2010s title among the re-runs. Newer horror showed too: Buddy (2026) climbed 58 ranks to #22, Wild Horse Nine (2026) climbed 39 ranks to #35, and I Play Rocky (2026) climbed 39 ranks to #58. October's film board is a seasonal chart with a few new releases mixed in.
App Store: the holiday wallet is waking up
Capital One Shopping advanced 44 ranks to #26 on the App Store's free chart over two weeks, and Capital One Mobile advanced 34 ranks to #6, a one-two that says holiday bargain hunting has started. Partiful, the party invite maker, rose 47 ranks to #35, the largest app climb measured. Lyft climbed 41 ranks to #11. The Waymo app rose 22 ranks to #68 as Toyota and Waymo announced plans to trial the bZ4X in Japan during 2027, news carried by 10 outlets including Reuters (the announcement). Uber rose 17 ranks to #8 and Taco Bell rose 19 ranks to #62. The month's current #1 was TikTok Pro - Events.
Spotify: podcasts about money and murder
Acquired climbed 65 ranks to #118 on Spotify's 14-day board, the largest podcast climb measured. TRIGGERnometry rose 54 ranks to #122 and If Books Could Kill rose 54 ranks to #142. Freakonomics Radio climbed 43 ranks to #151. True crime joined the climb: Just Creepy: Scary Stories rose 36 ranks to #53 in the run-up to Halloween, and The Big Picture rose 36 ranks to #48. The pattern is plain. Business curiosity and true crime carried October's podcast listening, with a seasonal horror bonus in the final week.
Steam: Call of Duty is back in the top five
Call of Duty rose 10 ranks to #5 on Steam's most-played board over two weeks, rejoining the top five alongside PUBG, which rose 3 ranks to #4. Wallpaper Engine rose 10 ranks to #14, an odd chart neighbor for a shooter. TBH: Task Bar Hero climbed 7 ranks to #13 and VRChat gained 4 ranks to #21. Slay the Spire 2 rose 3 ranks to #18. Counter-Strike 2 was #1 in the latest snapshot, still unchallenged at the top.
X: football, football, football
The Dolphins jumped 48 ranks to #46 on X's 7-day trending board, the largest sports climb measured anywhere this month. The Bengals rose 11 ranks to #88 and the Ravens rose 9 ranks to #55. Sunday Night Football gained 3 ranks to #60 and the Chiefs rose two ranks to #3. X remains the board where the weekend's games become Monday's conversation, and October's biggest movers there were all NFL.
Amazon: hosting season, visible in the margins
Dawn dish soap's refill jug rose 17 ranks to #51 on Amazon's best sellers over two weeks, the largest climb on that board. Amazon Essentials cotton swabs rose 11 ranks to #150. Everything else barely moved: The Correspondent climbed 2 ranks to #40, TERRO ant traps climbed 2 ranks to #43, Theo of Golden climbed 1 rank to #32, and Mighty Patch climbed 1 rank to #36. Amazon's top sellers are a slow board, Amazon Basics batteries at #1 and #2, and October moved it mostly at the margins.
The boards that went quiet
Five boards turned over completely between snapshots, meaning no item appeared in both and no rank change could be computed: Reddit hot posts, YouTube trending, Pinterest trending, Polymarket top markets and GitHub. That is itself a signal. These are the fastest-churning boards in the set, and October's churn was total. The Reddit data is also the oldest in the set, a snapshot from October 27, so read its leaderboard as a late-October freeze frame: the Dinnie Stones lift led at #1, with Neil Young's suit against Trump over unauthorized music use at #4.
Where October left each board
The month's #1s tell the story in one line each. TikTok: #halloween. Pinterest: "fall nails". YouTube: a Halloween songs compilation. IMDb: You Can See Everything. Google Trends: "patrick stewart". Wikipedia: Haley Stevens. Spotify: The Joe Rogan Experience. Steam: Counter-Strike 2. App Store: TikTok Pro - Events. GitHub: thedotmack/claude-mem. Polymarket: the Senate swing states market. X: football chatter. October belonged to the calendar and the postseason.
