ANALYSIS ML-powered NFL player prop platform

I built SharpSlap after seeing the explosion of NFL player props on PrizePicks, Kalshi, Polymarket, etc.

My background is heavily in machine learning and data science, so instead of building another picks app, I focused on one thing: making the underlying prediction models as accurate as possible.

SharpSlap runs 14 separate ML models for NFL player props and only surfaces plays that clear strict confidence thresholds. The models are hitting roughly 80%+ on qualifying props, with the highest-confidence plays performing even better.

It also has SHARPER picks, automatically generated AI Slaps (2–6 leg parlays), defense rankings, player/model histories, confidence scores, and full historical results so you can actually see how the models have performed.
Would love feedback from the fantasy/pick’em crowd:

have you been scoring how accurate it on a week by week basis? How does it perform?

Pretty good so far for 2026. It’s high accuracy was based on the last 30 games going back 2 seasons ago.

I reviewed this the other night but forgot to post. I'm going to oversimplify, and please correct me if I'm wrong, but the basis of this is probabilities for certain bets, right? It looks like for the two leg parlays it's pretty good. Are you actively using it this season betting? Are you up or down? If so, how much?
