What is the BoyleSports Celtic treble boost?
BoyleSports have enhanced the price on Celtic winning all three domestic trophies in 2026/27 — the Scottish Premiership, the Scottish League Cup (Premier Sports Cup) and the Scottish Cup — from a standard 8/1 to a boosted 10/1. It’s a singles-only price with a maximum stake of £10, available to online customers and to Boyle Xtra cardholders in shop. A £10 bet at 10/1 returns £110.
Can Celtic win the treble in 2026/27?
They’re the obvious favourites, but it’s not the certainty a boosted treble might suggest — and that’s exactly why it’s worth a look at 10/1.
The case for. Celtic are 4/5 to retain the Premiership and are short-priced favourites for both domestic cups, backed by the strongest squad in the country and a relentless recent record of trophies. They completed the domestic double last season and have made the treble a regular target rather than a one-off ambition. Under Martin O’Neill, the winning machinery is intact.
The case for caution. Last season was far from a procession. Celtic took the title by just two points from a Hearts side that led the table deep into the campaign, with Rangers third. Hearts, at 6/1 for the title, are the shortest-priced outsider the Premiership has seen for years, and the cups are one-off knockouts where a single off-day ends the whole treble. Celtic have also fallen at the final hurdle before — the treble requires all three to fall right across a long season.
That balance is the point. At 8/1 the treble was a fair price; the boost to 10/1 tips it towards value on a team that will genuinely contend for all three.
How the Scottish season lines up
The three legs of the treble play out across the campaign, giving the bet a long runway:
- League Cup (Premier Sports Cup): group stage from July, with the final on 13 December 2026 — the first trophy up for grabs.
- Premiership: runs from the opening weekend of 1–2 August 2026 through to May 2027.
- Scottish Cup: the classic spring knockout, concluding at Hampden in May 2027.
For the bet to land, Celtic need to come through the League Cup knockouts, hold off Hearts and Rangers over 38 league games, and win the Scottish Cup — a lot has to go right, which is what the 10/1 reflects.
