Demand
7/10

Strong real-world demand: MLB trade deadline 2026 is Aug 3, Red Sox/White Sox are central figures in deadline coverage (MLB.com, Yahoo, MassLive all running dedicated stories), White Sox linked to 10 of ESPN's top 25 candidates, and the AL Central race plus Boston's surge create a genuine narrative window.2026 MLB Trade Deadline questions, rumorsEvery Player Linked to Chicago White Sox for 2026 MLB Trade Deadline

Crowded field: Baseball Predict, ProbWin, mlbprediction.com, sports-ai.dev, and Baseball America all already publish AI/analytics-driven MLB previews and game predictions, though none narrowly focus on series-level + trade-deadline narrative fusion.Baseball Predict — AI MLB Predictions, Scores & StatisticsFree MLB Picks Today — AI Baseball Predictions 2026 Season | ProbWin

Monetization
5/10

Mixed: Lumenalta 2025 survey shows fans willing to pay for personalization, and premium baseball newsletters exist, but free AI baseball competitors (ProbWin) and subscription fatigue in sports content pressure conversion; likely needs a free tier with paid premium.New study: Fans want more from teams -- and are willing to pay for itBeyond Price Cuts: Fighting Subscription Fatigue With Richer Content Experiences

Longevity
4/10

Inherently seasonal: MLB active window ~6 months/year, trade-deadline peak is a 3-4 week spike, and once Boston falls out of contention the specific Red Sox/Sox hook evaporates; product must repurpose for offseason or other sports to sustain.Red Sox 2026 Trade Deadline pieces - MLB.com

Feasibility
8/10

Trivial to build: MLB Stats API is free, team/player news is widely scraped, and an LLM can synthesize series previews and hot/cold streaks from box-score data with minimal engineering.
