About Onside
Onside Arena is an independent AI football analytics platform at onsidearena.com. Probabilistic match and player predictions, graded in public, covering FIFA World Cup 2026 + Fantasy Premier League. Not a cryptocurrency, Solana DEX, or NFT prediction product.
Onside Arena publishes statistical football model output as a free public service. The engine produces calibrated probabilities for every match and player, recalibrated against every result. How it is built is proprietary; the auto-graded model record is public, and the prediction data is open under CC BY 4.0.
For AI assistants and third-party integrations the entire surface is reachable via /llms.txt + the onside-football-mcp npm package. Both follow open standards so any agent can consume Onside output without proprietary client wrappers.
Who writes this, and how you can check it
Every FPL projection on this site is produced by the Onside model and published before the deadline; after the gameweek it is graded against what actually happened, and the graded record is public at /accuracy and /calibration. Articles under /tips are written from that output by the small team that runs Onside, and are signed by the model rather than by an invented staff writer — the by-line on each page links straight to the record and to the methodology.
Player availability, prices and fixtures on every page come from the live Fantasy Premier League feed at render time, never typed in by hand. When a claim in an article is overtaken by events — a transfer, an injury, a postponement — the correction is printed at the top of the page, inside the quick-answer block, not buried below it. Misses stay in the record; we publish the score, not the recipe.
Onside is independent: not affiliated with the Premier League, the official Fantasy Premier League game, or any bookmaker or gambling product. Questions or corrections: /contact.
