Polymarket just increased its new user sign-up bonus from $20 to $50 for qualified users. Enter the Polymarket promo code RATE during signup, deposit $20 and get a $50 bonus to your account once the deposit clears. The timing lines up perfectly with two NHL playoff games tonight, two NBA Game 6 elimination spots Friday, and the opening rounds of the PGA Championship at Aronimink.

The new bonus arrives the same week Polymarket officially opened its US exchange to all iOS users, ending a six-month waitlist that grew over 1.4 million signups. iPhone users can now download the app and start trading for the first time since the US relaunch.

Polymarket odds for tonight’s NHL games and Friday’s NBA Game 6s

Four second-round series have elimination implications between tonight and Friday. Here’s how Polymarket is pricing the series outcomes:

MatchupSeries statePolymarket series winner
Canadiens at Sabres, Game 5 (tonight, 7 ET)Tied 2-2Sabres 55%
Golden Knights at Ducks, Game 6 (tonight, 9:30 ET)Vegas leads 3-2Knights 60%
Pistons at Cavaliers, Game 6 (Friday, 7 ET)Cleveland leads 3-2Cavaliers 75%
Spurs at Timberwolves, Game 6 (Friday, 9:30 ET)San Antonio leads 3-2Spurs 91.5%

The two NHL series are close to coin flips at the series level. Buffalo defends home ice tonight in a 2-2 series, while Vegas plays a road elimination spot in Anaheim, with a loss sending the series back to Vegas for Game 7.

The NBA picture is less suspenseful. San Antonio’s 91.5% reflects a 29-point Game 5 statement and the comfort of a potential Game 7 back home. Cleveland’s 75% is built on home court advantage with Detroit facing elimination on the road, though Detroit has already come back from a 3-1 hole this postseason against Orlando.
