No sportsbook affiliates. No paid placements. No operator revenue.

A single revenue source: paid subscriptions. The Pro tier ($29/month or the founding annual $199/year plan when available) and the API Beta add-on ($99/month per sport for active Pro subscribers) are the only ways money enters the business. There is no operator-side income of any kind.

• Run sportsbook affiliate links anywhere on the site.
• Place outbound “sign up at Operator X” buttons on signal cards, market boards, or recap pages.
• Receive bonuses, boosted-odds inducements, or revenue share from any sportsbook.
• White-label operator comparisons or promote operator-of-the-month rankings.
• Sell user data to operators or to third parties of any kind.
• Accept payment in exchange for changing a signal grade, model probability, or published outcome.

• The model. Probabilities are derived from data — no operator economics enter the inputs or weights.
• The grade. STRONG / LEAN / WATCH / SKIP is computed from the gap against no-vig consensus, never from an operator partnership.
• The methodology. Inputs, pillars, and signal counts are documented at /methodology.
• The published record. Wins and losses are graded the same way every night, with no operator-favored carve-outs.

Posterior reads Polymarket as a publicly-available price source on MLB game-level moneyline markets (see /mlb/live). The data comes from Polymarket's public Gamma REST API.

• Posterior is not a Polymarket affiliate, partner, or referrer.
• Posterior does not custody USDC, hold Polymarket positions, or route trades there.
• Posterior does not use Polymarket's trading SDK (@polymarket/clob-client); we use only the public read-only REST endpoints.
• Polymarket prices appear in our published surfaces as an independent second opinion alongside sportsbook consensus. They do not enter the model's grading math.

If Posterior's business model ever evolves to include a sportsbook relationship — affiliate, sponsorship, or otherwise — or if our posture toward any other market venue (including Polymarket) changes, this page will be rewritten in full, the change dated, and every affected surface labelled. The default posture is independence; any deviation will be disclosed explicitly rather than buried.
