How To Bet On The US Election – What Are The Best Odds?

Ask one hundred people what they believe is the single biggest betting market of all-time, or will be in 2024, and they would probably reply with a sport. The World Cup or Super Bowl. The Grand National or Kentucky Derby perhaps?

Few, I suspect, would even consider the answer to
be politics.

2016 saw politics twice break the all-time record on Betfair – the world’s largest peer-to-peer betting exchange.

First there was the UK’s referendum that led to
Brexit. Then Trump versus Clinton for the White House.

On current trends, the sequel involving Joe Biden
will surpass both.

Where To Get A Piece Of The
Action!

Though largely pioneered in the UK – home to the
most liberalized and mature betting industry – political betting is now a
global phenomenon.

PredictIt has emerged as an outstanding exchange,
specializing in politics and current affairs. You can risk up to $850 on any of
their impressively wide array of election markets.

If you live in a country where Betfair is legal
(most, but not the USA, Canada, India or China), this is the go-to exchange
where the biggest sums are traded. Over £250M was traded on their 2016 election
markets and the 2020 projection is higher.

Notable alternatives to Betfair are the Smarkets exchange and conventional sportsbooks Paddy Power, Ladbrokes, William Hill and Betfred.

What Are The Latest Odds?

Betting odds are displayed differently between
firms and countries. PredictIt quote a price in monetary terms that amounts to
a percentage.

For example, the quote for Joe Biden is 58 cents.
The options are to ‘Buy Yes’ at 58, or ‘Buy No’ at 43. The result makes up 100,
so a Biden backer is risking 58 to make 42 profit. Or if you want to oppose
Biden, risk 43 to win 57.

UK betting firms use either fractional or decimal
odds. Biden’s PredictIt odds would equate to 8-11 or 1.72. Or -137 on a US
sportsbook.

Notably, the PredictIt odds to oppose Biden are
more generous than in the UK. On Betfair, the option is to ‘back’ or ‘lay’
(oppose) and odds are expressed in decimals. His odds are 1.85 to back or 1.86
to lay. 

In this case 1.0 amounts to your stake and anything
above that is profit. So backing Biden for £100 at 1.85 would return £185 if he
wins.

Alternatively, if you want to back Trump these are
the odds. PredictIt offers 46 cents to ‘Buy Yes’ or 55 to ‘Buy No’. Betfair are
2.26 to back or 2.28 to oppose.

Americans Are More Pro-Biden
Than With UK Firms

It is striking how close the betting is, especially
in the UK, compared to opinion polls.

Current odds imply between 54-58 percent chance of
a Biden win. That figure varies between 77-90 percent with polling models.

This differential has become a hot topic of
election conversation. Why do betting markets rate Trump so much higher than
the polls?

Most obviously, the memory of 2016, when Hillary
Clinton was well ahead in the polls and a short-priced favorite. Trump’s upset was
a huge betting story which created a narrative, that the polls were fake and
never to write him off.

Why 2020 Is Very Different
To 2016

I’m very much in agreement with the pollsters and
regard Biden an outstanding value bet at these odds. Comparisons with 2016 are
highly dubious.

Trump won by a whisker, on a very low total,
benefiting from stronger third-party challenges than will be the case this
time. He’ll need to win many millions more votes this time, amid a higher
turnout.

The polls were only 1-1.5 percent wrong and
sampling errors have been corrected. The trends regarding Trump approval and
the generic ballot have been incredibly consistent since 2016, and translated
into votes at the 2018 mid-terms.

Trump is trailing by around 7 percent and that
looks more or less fixed, with barely any persuadables.

Understanding The Electoral
College Is Essential

Of course, the presidency isn’t decided by the
popular vote.

Trump lost by 2.1 percent in 2020 but won the electoral college. This consists of votes awarded by each state to their particular winner – for example Florida awards 29 out of 538 in total. 270 are needed to win.

Note, betting is available on all the individual states and the electoral college totals.

Again, I suspect the memory of that freakish result
is leading gamblers to think Biden’s task is harder than it really is. Here’s
how he can become President.

Biden’s Path To Victory

First, hold all the states won by Hillary Clinton
in 2016. Only these three are imaginably under threat.

Here’s how many electoral college votes each
awards, along with Biden’s chance as implied by odds.

  • Minnesota: 10 votes, 76 percent chance.
  • Nevada: 6 votes, 72 percent chance.
  • New Hampshire: 4 votes, 71 percent chance. 

Retain them for the Democrats and Biden would need
to gain states offering 38 electoral college votes to reach the winning target
of 270.

These four pick-ups represent his easiest route:

  • Michigan: 16 votes, 70 percent chance. 
  • Arizona: 11 votes, 62 percent chance.
  • Wisconsin: 10 votes, 67 percent chance.
  • Nebraska 2nd District: 1 vote, 65 percent chance.

Beyond that, Biden is favorite or competitive in
all the following states won by Trump in 2016:

  • Pennsylvania: 20 votes, 60 percent chance
  • Florida: 29 votes, 48 percent chance
  • North Carolina: 15 votes, 45 percent chance
  • Ohio: 18 votes, 35 percent chance
  • Iowa: 6 votes, 34 percent chance
  • Georgia: 16 votes, 30 percent chance.
  • Texas: 38 votes, 23 percent chance.

Those numbers imply a big mismatch with the next president odds.

If you think Biden will win, back him to win the
presidency. If you prefer Trump, back him for Pennsylvania and Florida.

He won’t win without at least one, very probably
needs both, and could win both but still lose the presidency.

These are just some of the betting options. Others
include vote shares, vote totals, handicaps, third place.

Or if you fancy some long-range speculation,
Betfred have priced up the 2024 election already. Donald Trump is a 16/1 chance
while Ivanka is at 33/1.

My tip? Kamala Harris at 11/2.
