Looking to use prediction markets? A sports bettor gives his pros and cons

· Yahoo Sports

Prediction markets. Do I have your attention? 

Like cryptocurrency, NFTs, or any other buzzy-term of the last decade or so, if you're online at all, you probably haven't been able to avoid all the talk — both positive and negative — about the newest outlet for weighing one's opinion about what's going to happen in a given game. There's been a Netflix "Instadoc," and features on news magazine shows, ranging from the serious ("60 Minutes") to the satirical ("Last Week Tonight").

It wasn't that long ago that the repeal of PASPA (Professional and Amateur Sports Protection Act) in 2018 finally meant that you could eventually make a single-game wager legally in your state, or one nearby. Just a few years later, and not only has a loophole been utilized for states that haven't legalized sports betting, now you can put money on things as obscure as:

  • Will there be a confirmed alien landing?

  • The Rotten Tomatoes' score for an upcoming movie

  • The Release Date for not only Grand Theft Auto VI, but the trailer for GTA6

  • Any number of things involved Drake, Taylor Swift, Bad Bunny and many more of world's rich and famous

This is a conversation for sports bettors, though.

For those that have gone through the process of funding accounts at various sportsbooks, only to have noticed the proliferation of prediction markets, you could be contemplating what role this new category will have in your sports betting journey.

If that sounds like you, check out my list of pros and cons of prediction markets from a veteran sports bettor.

We're keeping this in the context of those who are looking to be profitable long term in the act of taking their earned money and risking it on results they have no control over, with the hopes of winning more money. 

If that sounds like "betting" to you, you're not alone. However, for political purposes, certain factions are paid handsomely to create a definition that drifts away from the risk/reward nature at the root of making a bet; instead, calling it "financial derivatives and forecasting tools."

Whether we're buying that self-serving argument or not, it is appealing to simplify betting in a way that more closely resembles something like a peer-to-peer wager, made on a barstool at some watering hole before the game starts. 

If you're afraid of the big, scary oddsmakers with all the alleged inside sources, and deep-seeded knowledge of all the teams, then trying to pick off one individual's bad offering, versus the more commonly-available lines offered to millions, makes more sense as a potential opportunity. 

In traditional sports betting, the price is set by the sportsbook via the line (e.g. Saquon Barkley over/under 98.5 rushing yards at -110/-110) and it's up to the bettor to accept one side or the other. In the prediction market format, users are able to set their lines and odds in order to coax action, effectively "making" the market.

Occasionally acting as the oddsmaker is an appealing feature to someone with a perceived edge on anything from the side or total, to the player prop market. On top of that, if you come up with an offering that isn't available via traditional sportsbooks, you might be able to exploit an edge.

Let's be honest, the betting menu has gotten out of control. Somewhere along the way, we went from just wanting a similar experience to either the brick-and-mortar sportsbooks of Las Vegas or the bare-bones spread/moneyline/total options available via offshore websites, in an effort to add interest to the games we all watch, to being inundated with hundreds of uber-specific options for each and every remotely high-profile game. 

A less-is-more approach provides more focus on what to bet, while limiting distractions. Often, as bettors, if we feel we have a beat on one of the main markets for a game, we can get a little loose, applying that opinion to too many prop bets, just because they're offered.

One of the biggest hurdles for someone who works in sports betting content is guiding novice bettors' toward a firm understanding of what the odds really mean in terms of probability. 

When making bets, we speak in terms of underdog odds of +150, 3-to-2, or 2.5, but not all bettors instantly translate those numbers into their implied win probability of 40% when considering how likely the event or result is to occur — a crucial element in understanding sports betting.

Prediction markets already speak in that language, with available selections listed with their perceived probability:

Also, every offering is priced between zero cents and one dollar, which is akin to the 0-100 scale that many bettors and oddsmakers use to create their market ratings for sports teams. 

Bettors who use even one of these prediction market outlets will get a better grasp of how bets are an exercise in probability, which can only help in whatever way they continue their betting journey.

We'll stop short of calling those who've been deep in the weeds on prediction markets the "cool kids in school," but there is something to be said about wading into waters that have been populated by early adopters. 

Let's be crass and characterize these hundreds and thousands of early-adopters as "sharp," and the millions betting over at the legal sportsbooks as "square." Experienced users making the market should be tougher to beat. 

Using our example of a singular offering from a lone user, it's a lot easier for that entity to have inside information about something that may change the perceived value of one of the teams, or players, in an upcoming game. 

Yes, at its core, betting something like the Jaguars -3 at -102 odds when it's available at -110 at a traditional sportsbook is technically good business, but if a sharp bettor is offering that, it's more than likely that Jaguars -2.5 (even at, say, -120) will be available at some point throughout the week. If you're sharp enough to swim with the PM sharks, you should be switched-on to the degree where you can get the best bet available throughout the week, as the masses weigh in. 

Betting of any kind provides a stern test in managing oneself in an industry where addiction exists. You don't have to be a sports betting addict to find yourself skimming through the deep menu of derivative markets or live-betting options for your favorite sports, nor are you an addict if you veer into betting on sports you wouldn't otherwise consume, but having those auxiliary options wasn't front of mind when most began to activate for widespread legalization.

Now, with the endless offerings from prediction markets, not only do you have sports to bet on, but you're just a click or two away from betting on specific words said on company earnings calls, the Strait of Hormuz, the weather and a myriad of options where even more restraint is required. 

This isn't about guilting anyone about their personal morality when it comes to who's involved behind the scenes in various prediction markets, but depending on where you'd like to think you draw the line about who you do business with, there's definitely a "do your own research" element to picking where you're going to ply your trade. On top of that, a quick search and view of the marketing and advertising techniques used by many of these companies could very well turn you off entirely. Finally, who could blame you if you don't want to be trading with a company that offers markets on things like the probablity of a drone strike. 

Even with an increase in focus on the legitimacy of sports betting with compliance watchdogs and judicial oversight, the terms and conditions you agree to leave you vulnerable to the occasional horror stories about sportsbooks voiding bets, and/or not paying out withdrawals. Imagine how sketchy things could get when dealing with an operation with considerably less legislation and regulation.

Plus, in a worst-case scenario for prediction markets, a change in federal administration leaves open the possibility of a shutdown we haven't seen since online poker's "Black Friday." 

Like most things in life, you should weigh these pros and cons in a way that makes the most sense to your personal values, how you want your sports betting experience to look and feel, and not by what you're being sold in advertisements, or an effort to keep up with the ever-changing times.
