Betfair Customer Services 19 Mar 18:27
Dear BetFair, I hope you will answer the following:

Under current UK regulations you are not required by law to inform your customer base of changes in advance, but under FSA regulations and European Law you would be. Given the strength with which you defended the GC&#8217-s consideration that exchanges should be FSA regulated when the Gambling Bill was first drafted, don&#8217-t you think it would have been wise or prudent to satisfy the most basic of FSA regulations too – and advise your customer base of material changes to the bet matching algorithm: the key component of the exchange software we all trade on, and one which matches wagers totalling billions of pounds in the UK today.

I am not sure you are correct here: what we were doing here is entirely in line with our licence and what we have always said we do. If you look at repeated statements made about what we are, I (this is Mark [Davies]) have always stated publicly on behalf of the company that the best definition of a betting exchange is a bookmaker which uses technology to manage its risk perfectly. This is what we were doing here: matching bets in a manner which meant that we, as an operator, had no exposure to the outcome of the event. People have always described Betfair as P2P and told me that our description of the company in these risk-based terms was spin. The reality is the opposite: Betfair is a many-to-many system where demand between customers is matched such that the operator of the exchange does not have risk to the outcome of the event. It is precisely on this basis that we have always been licensed as a bookmaker.

Graham “Sharp” Minds, in a comment on Midas Oracle:

I am one of the people who Ed Murray has referred to in this blog. I was interviewed at Hammersmith by Betfair during the summer. For the time being I am going to concentrate on what Betfair has finally admitted from the past, present and future plans that betfair outlined to me.

&#8220-Loki Lab Rat 18 Mar 08:20 I can answer this one quickly. There is a trading team based in Malta which manages the risk around the multiples product. They have software which tells them what the risk is associated with a potential result is and suggests what hedge bets can be placed to mitigate that risk at current exchange prices. They then place the hedge bets to manage the risk. They place the bets using the same software as everyone else using the site and respecting any in-play delays.&#8220-

There is 3 objectives for the &#8220-Maltese&#8221- trading team, &#8220-Maltese&#8221- is in quotation marks because betfair were unclear to me about who and what parts of the trading team were still going to be based in London and those who were going to be in Malta.


i) Hedging
ii) Trading
iii) Arbing

All 3 amount to the same thing, Betfair playing their own markets.

On each of the 3 points

i) Hedging, this is what Betfair has admitted to and has been doing to from day 1 of the multiples. Betfair admit to taking the other side of the bet for the mutiples, so I guess like any other bookmaker it is only natural they &#8220-hedge&#8221- their bets to reduce potential liabilites.

However unlike traditional bookmakers, who will lay off a multiple when one runs up, the bets taken by Betfair multiples are placed directly back into the exchanges before they &#8220-run-up&#8221-.

This is one of the reasons behind the mutliple groups, they look at the back/lays placed on the mutiples for the first match and then the bets are placed into the exchange to reduce the liabilites and to cream off the difference between the price they have offered and that offered on the exchanges.

ii) Trading, this is what betfair are attempting at the moment, albeit unsuccessfully from what I last heard. Betfair have admitted they change their hedging positions, this by definition is trading. however the most serious aspect of their trading, is the in-running trading.

If betfair have accepted liabilities X &amp- Y for events A and B being the outcome of a match, then why would liability X for A or Y for B be no longer acceptable during a match unless there was an advantage to be gained by trading betfair’s position in-running?

Afterall, on betfair’s exchange with a 100% book, whether that 100% book was an efficient or inefficient, the net expectation of betfairs position would remain the same if they were trading hedging positions blindly to &#8220-balance&#8221- the liabilities.

In the instance of an inefficient market, if betfair were blindly trading (i.e. not using odds compilers, traders or other means to form an opinion on the market) in-running then there would be no net gain as betfair would be equally likely to be on the efficient and inefficient prices and the differences would average out.

iii) Arbing, this is betfairs ultimate goal for the multiples. If this new cross-matching bot is being called a superbot, then this will be the hyperbot. A bot which will perfectly arb the mutiple bets into the exchange so betfair can make money from it’s mutiples operation risk free.

But if betfair are denying that they never form an opinion to a market and place bets accordingly and they have no plans to do this in the future either. Then why are they covertly recruiting academics from universities, odds compilers from the bookmakers and recognised traders from their own customer base?

If betfair are playing their own markets, then what is to stop them abusing the position they have by owning the exchange. Having worked for several bookmakers in the past, I have yet to know one who would voluntarily wait 5 secs to place their &#8220-hedges&#8221-, wait in the queue like everyone else, make trading decisions according to the flow of money or not use their &#8220-warm sources&#8221- wisely.

I can answer this one quickly. There is a trading team based in Malta which manages the risk around the multiples product. They have software which tells them what the risk is associated with a potential result is and suggests what hedge bets can be placed to mitigate that risk at current exchange prices. They then place the hedge bets to manage the risk. They place the bets using the same software as everyone else using the site and respecting any in-play delays. The line about &#8216-opportunities in-play&#8217- refers to the match situation and is nothing to do with beating the delay.

For example, when just about every favourite won their international Euro 2008 qualifiers in early June last year (known as &#8216-Black Wednesday&#8217- in some quarters), Moldova scored late-ish against Greece to square the match. The multiples team heavily laid the draw as the match drew to a close as it was a much better potential result than a Greek win. That meant that when Greece did score with the last kick of the game, our losses were mitigated to some extent by the hedge bets placed in-running.

The multiples product is run under Betfair&#8217-s Maltese bookmaking license and is regulated by the LGA there. Therefore the team has to be based in Malta. The operation is an arms-length operation &#8211- there is no special access to any functionality or data from the exchange.

Loki Lab Rat:

frog2, It is best I leave questions on cross matching for the Q &amp- A. I am not really that close to the project. I just thought I would answer the one on the multiples team to prevent any speculation getting out of hand.

Rab Bibater in a comment on Midas Oracle:

It is also pertinent that this team operates under Maltese jurisdiction- which of course puts it outside the scrutiny of the UK’s Gambling Commission!

However, I think there is also another issue that needs to be explored, and that is the general efficacy of a policy that allows Betfair’s own employees to trade on their exchange. Many people within Betfair have access to historical trading data unavailable to the broader betting public- such as what stables are backed and when- the significance of early money for particular horses etc- some are also able to access the betting records of individual persons. I specifically remember a comment made on Betfair radio concerning the boys in the office and how they had mopped up all the value regarding a particular horse from a gambling yard. The problem for Betfair, and one that is not likely to go away, is that nobody is sure any longer as to who it is they are actually trading against.

No offense, but I think Radley Balko is the most valuable blogger in America right now.

Are you a better predictor than John McCain?

John McCain

They would do anything to sell politics, these days. :-D

Foreign Policy:

It&#8217-s a clever marketing ploy by team McCain, but why stop there? Why not have the candidate take positions in predictions markets such as Intrade? Wouldn&#8217-t we rather know how prescient Senator McCain is about the odds of bird flu striking the United States by the end of September, the chances Pervez Musharraf will step down as Pakistan&#8217-s president anytime soon, or the likelihood of a peace treaty between Israel and the Palestinians by January 2009? Put your money where your mouth is, senator.

InTrade-TradeSports and BetFair-TradeFair should let traders opt to make public their positions, and they should create dynamic prediction registries and leagues.

Forum Q&amp-A Session

Betfair Customer Services 17 Mar 11:21

As announced last week we’ll be hosting a Q&amp-A session on the forum this Wednesday evening (19th March) between 6pm and 7pm (UK Time). The purpose of this Q&amp-A session is to answer questions regarding Betfair’s new bet matching logic. To help us get through as many questions as possible you can send them in advance to [email protected]. Unfortunately it is not possible for us to respond to each email individually but we will attempt to answer all questions raised via the live Q&amp-A session.

We realise that customers would appreciate the chance to have questions answered on other topics too, but we want to focus this initial session on just the new bet matching logic to ensure that we answer as many questions as possible. For those customers who have questions for Betfair that aren’t related to this topic we’ll be reintroducing regular forum Q&amp-A sessions over the coming weeks. We’ll post more information about those sessions nearer the time.

We hope you find this session helpful and informative.

Inkling Markets, one year later

Much, much better. Last year at the same time, in March 2007, I was selectively critical of some of the statements they did put in their (now old) version of their website. Adam Siegel has made good progress in mastering and conveying the problematic of enterprise prediction markets. I think that if Inkling Markets can truly deliver a service that can help companies mitigate business risks, and if they can prove positive results, then their client roll could be multiplied by a factor of 1,000 or so in the next 10 years.

Adam Siegel:

Two years ago the only way to run a prediction marketplace was to roll your own or call a vendor/consultant and have them set up software and run markets for you. It took many weeks, often months. Today with Inkling Markets it take seconds. […]

[#1] Improve forecasting of key performance indicators
Track and raise awareness of key success metrics to identify and mitigate risk factors before it&#8217-s too late.

[#2] Expose product quality problems early
Identify design and production anomalies before a product (physical or virtual) is brought to market to avoid expensive repairs and recalls.

[#3] Predict risk to your supply chain

Run a &#8220-web&#8221- of markets about the risk factors to your supply chain to predict internal and external events that would cause inefficiencies or disruptions.

[#4] Foster a culture of innovation
Determine which new ideas and process improvements will have real business impact vs. the &#8220-nice to have.&#8221-

[#5] Create new interactions with users

Build a dedicated community of users around a marketplace of questions relevant to your business area and brand. […]

Adam Siegel (Inkling Markets CEO) in Forbes:

[Prediction markets] can significantly:

  1. improve forecasts of key performance indicators,
  2. provide a more realistic understanding of project-completion dates,
  3. identify quality-control problems early in the development life cycle,
  4. improve demand forecasts within the supply chain,
  5. and allocate resources more appropriately across research-and-development projects.

We will never have a perfect model of risk

The most credible explanation of why risk management based on state-of-the-art statistical models can perform so poorly is that the underlying data used to estimate a model’s structure are drawn generally from both periods of euphoria and periods of fear, that is, from regimes with importantly different dynamics.

Wiki News (Wikipedia&#8217-s twin site devoted to news edited by anyone) has a long article on that scandal, agitated by ValleyWag, and denied by TechCrunch. I&#8217-m on the side of ValleyWag&#8217-s Paul Boutin, on that one. The media should start asking the hard questions. [I’m not saying that Jimmy Wales, who has earned our respect, is a culprit. I’m just saying that the media should investigate more on that.] And blogger Mike Linksvayer, who urged us many times to contribute US dollars and French francs to Wikipedia, should do too.

Based on the analysis of some 600,000 official Iraqi documents seized by US forces after the invasion and thousands of hours of interrogations of former officials in Saddams government now in US custody, there is no evidence Saddam Hussein had ties to Al Qaeda.
