About Prediction Market to Sports Odds Converter
Append sportsbook-style odds next to prediction market prices (Decimal, American, Fractional) with optional fee adjustment.
Chrome extension that appends sportsbook-style odds next to prediction market prices on Polymarket and Kalshi. Shows Decimal, American, and Fractional. Optional fee adjustment (in percentage points) to model effective probability before conversion.
Finds text like 55% or $0.55 and computes:
Decimal: 1 / p
American: if p >= 0.5 → -(p/(1-p))*100, else ((1-p)/p)*100
Fractional: (1 - p) / p as a simplified fraction (approx.)

Filled points are observed values; hollow points come from Internet Archive snapshots of the listing page. Dashed segments span periods with no observations — values between points are not interpolated.
Each band is one page of 20. Users on a linear scale. Placement is projected from users, so it can differ from the marketplace's own sort order. Hover a dot to see the listing.
Covers every Chrome Web Store extension with at least 100 users, found through the store's public sitemap. User counts are read from public listing pages. The 10% most-used extensions are refreshed daily, the next 40% weekly and the next 40% monthly; the least-used 10% are not refreshed. Google displays rounded user counts (and caps the display at 10,000,000+), so small changes may not be visible. Rating counts above 1,000 are rounded (e.g. 1.6K).
