The World Cup: academic predictions and gambling markets
Dr Nicolas Scelles and his team of researchers at Stirling University made several predictions about the World Cup, and the results of specific matches. Several of Dr Scelles’ predictions appear in postings on The Scorecard.
In response to these predictions, I have been tracking what would have happened if these predictions had been used by gamblers.
Figures are quoted to a £1.00 level stakes bet struck in correct score markets for every group stage match and the three knockout stage fixtures correctly predicted by the team.
Group stages
Six correct scorelines were predicted from the 48 group games:
Chile 3 Australia 1 - 15/1 BetVictor
Ivory Coast 2 Japan 1 - 11/1 Ladbrokes
Argentina 2 Bosnia-Herzegovina 1 - 17/2 Ladbrokes
Ghana 1 USA 2 - 12/1 Ladbrokes
Australia 0 Spain 3 - 13/2 Paddy Power
Portugal 2 Ghana 1 - 8/1 Ladbrokes / BetVictor
Win strike-rate: 6/48 - 12.5%
Outlay: £48
Return: £67
Profit: £19
Profit as % of turnover: 39.58%
Knockout stages
The team correctly predicted 8 of the 16 teams to reach the knockout stages of the competition (50%) and correctly predicted the group finishing position of 5 of those 8 teams.
Three knockout fixtures were correctly predicted:
Brazil v. Chile
Brazil v. Colombia
Brazil v. Germany
One correct score was predicted:
Brazil 2 Colombia 1 – 17/2 BetVictor / Coral
Win strike rate: 1/3 – 33.3%
Outlay: £3
Return: £9.50
Profit: £6.50
Profit as % of turnover: 216.6%
Total competition
Win strike rate: 7/51 - 13.73%
Outlay: £51
Return: £76.50
Profit: £25.50
Profit as % of turnover: 50%
As a footnote, a couple of random points of interest…
All group game prices were recorded before a ball was kicked in the competition. Using the Oddschecker site as a comparison tool, Ladbrokes were best or joint-best priced on 31 of the 48 matches (64.58%);
Brazil 1 Germany 7 was a score most could never foresee but Paddy Power reported four winning bets in the UK with one £5 wager recorded at 500/1;
Finally, spare a thought for the Ladbrokes punter who placed a £2 bet on Brazil 0 Germany 7 at odds of 1,000/1.
