Scarlets are slight favorites to win based on recent form and market movement, with typical moneyline odds around 1.85–1.95 versus Cardiff Blues at roughly 2.00–2.20; Scarlets’ stronger away form this season and a more consistent points-scoring backline explain the market tilt (odds indicative and should be checked closer to kick-off) DexWin - Best Odds on Your Favourite Sports.

The match kicks off at 7:45:00 PM local time on 19 December 2025; Cardiff Blues vs Scarlets in the United Rugby Championship will start at 19:45 GMT (19:45 UTC) if played in Wales, which is the local time zone for this fixture.

The game is scheduled to be played at Cardiff’s home ground, the Cardiff Arms Park complex (Cardiff Arms Park / Sophia Gardens precinct), which has a capacity of around 12,125 for rugby fixtures and features a compact pitch with typically strong home support and good broadcast facilities.

Our prediction: Scarlets to win or win +4.5 points (handicap) — moneyline around 1.90 for a Scarlets win and ~1.50 for the +4.5 spread; this combines Scarlets’ recent away scoring (multiple 20+ point performances in last five rounds) with Cardiff’s uneven defensive record this month, so a one-score Scarlets victory is the most likely outcome.

In head-to-heads over the last 10 competitive meetings, Scarlets have the edge with approximately 6 wins to Cardiff Blues’ 3 and 1 draw, average total points around 45 per game, and Scarlets averaging roughly 24–26 points in those fixtures while Cardiff average ~20–22; recent encounters show Scarlets taking the last two meetings leading into this season.
