ST Mirren vs Celtic: Celtic Draw No Bet

Celtic arrive in Glasgow with a 5.0 expected‑goals rate versus Mirren’s 2.0, and the model assigns a 76.3% chance of a Celtic win. The numbers point to a very high probability that Celtic will come out on top without risking a draw.

Both sides come in on contrasting recent runs – Mirren have been unbeaten in their last four league outings, while Celtic have secured three straight victories. The disparity in away scoring power, combined with a recent 6‑2 drubbing at Mirren’s ground, sets the stage for a one‑sided encounter.

Hamish's Verdict

Strong
Celtic Draw No Bet Won Strong · High win probability

Celtic’s win odds of 76.3% versus Mirren’s 8.6% translate to roughly a 90% chance that Celtic either wins or the match is voided on a draw, making the DNB market the clear choice.

Show the maths
The model assigns Celtic a 76.3% chance to win and Mirren an 8.6% chance to win, with a draw at 8.2%. For a draw‑no‑bet, the draw option is removed, leaving only Celtic and Mirren wins. Adding the two win percentages (76.3 + 8.6 = 84.9) and dividing Celtic’s win share (76.3) by this total yields 76.3/84.9 ≈ 0.898, or about 89.8% probability that Celtic will either win or the bet is voided, which is the basis for the pick.
Pick 2 · Both Teams to Score
Both Teams to Score — Yes Won 80.0% model probability

With ST Mirren averaging 2.0 expected goals and Celtic averaging 5.0, the model gives a 80.0% chance both teams find the net, ahead of the 20.0% it gives to at least one side being kept out.

Show the maths
BTTS probability is derived from each side's expected goals (ST Mirren 2.0, Celtic 5.0) run through the same Poisson goal-expectancy model used for the match result: 80.0% of simulated outcomes have both teams scoring at least once, versus 20.0% where at least one side is shut out.
Pick 3 · Total Goals
Over 2.5 Goals Won 90.2% model probability

Combined expected goals of 7.0 (ST Mirren 2.0 + Celtic 5.0) points to an open game, with the model giving Over 2.5 Goals a 90.2% chance against 9.8% for Under.

Show the maths
Total goals probability comes from the same Poisson model summing both teams' expected goals (ST Mirren 2.0 + Celtic 5.0 = 7.0 combined): 90.2% of simulated outcomes finish with 3 or more goals, versus 9.8% finishing with 2 or fewer.
Match Result Model

Our Poisson model, built from each side's real season scoring and conceding rates, has ST Mirren at 8.6%, the draw at 8.2%, and Celtic at 76.3% to win.

Most Likely Scoreline

The single most likely scoreline in our model is 1-4 at 4.7% — treat any single scoreline price with caution given how spread out the probability distribution is across a low-scoring match.

ST Mirren

WWWD

Mirren have not lost in their last four league games, beating Partick 1‑0 at home, Falkirk 2‑0 away, and St Johnstone 1‑0 at home before a 3‑3 home draw with Motherwell. The three clean‑sheet wins show defensive solidity, yet the modest scoring rate of two goals per game suggests they lack the fire‑power to trouble Celtic’s prolific attack, reinforcing the low win probability for Mirren.

Celtic

WWW

Celtic have collected three straight league wins, including a 1‑0 home victory over Dundee, a dominant 5‑1 away win at Kilmarnock, and a 2‑1 home success versus Falkirk. Scoring five in one outing highlights their scoring depth, confirming the model’s 5.0 expected‑goals figure and the high likelihood of a Celtic win.

Head-to-Head

In the most recent meeting on 19 April 2026 Celtic thumped Mirren 6‑2 at Glasgow, and earlier that season Celtic won 1‑0 on 11 April 2026. These results show Celtic’s clear superiority in head‑to‑head play, supporting the expectation of a Celtic victory.
