Prophet X Cancelled Bet on NHL Series Winner Citing 'Clear and Obvious' Odds Error Latest Scandal to Rock Sportsbooks

Move over PropSwap.  Prophet X is the latest sports betting site to come under fire for canceling a bet, blaming a "clear and obvious" error that was apparently of their own making.

Prophet X advised the gambler of the following:

"Hello, we are reaching to let you know you've had a play cancelled in accordance with our Too Good to Be True Policy.  Your play on the series winner: Jets or Series Winner: Avalanche was matched at odds that were a clear and obvious error."

Honestly @PlayProphetX this is bullshit pic.twitter.com/Bv09VSa6Va

They go on to cite their policy.

ProphetX's 'Too Good to Be True' policy is designed to protect customers from offering egregious errors on accident. This policy protects against egregious errors on offers, but will not apply on taken plays, new changes, injury updates, or in the case of live offers, changes in the score (unless covered by a case below).

ProphetX reserves the right under extraordinary circumstances to cancel plays that are the result of clear and obvious errors. Examples of clear and obvious errors include but are not limited to:

    Play placed at odds that are materially different from those available in the general market at the time that Order was placed. An example would be if a user requests a play with odds of -400 when the market is at +400.
    Plays where the outcome is already determined
    Plays resulting in a clear or obvious errors resulting from a technical issue

We understand that many players use ProphetX to create arbitrage opportunities - ProphetX is not responsible for positions on other platforms. If the offer is too good to be true, we encourage you to use your judgement before moving forward with any arbitrage opportunities.

The problem is that series odds are typically placed well ahead of any event taking place.  It is not immediately clear how soon after the bet was made that it had been cancelled.

The gambler did confirm the bet was placed after Game 1.

"Such a bullshit move by ALL books.  If they make the error, and we capitalize, then that’s on them. No need to punish the customer for half-ass work on the books’ part."

"Wait, so they are punishing you because they fucked up? Lol."

lol this is a wild thing to do right after they sent out this tweet with roughly the same odds ratio between their exchange and traditional books. https://t.co/xlwoURnwr2

Some on Twitter believe this bet was perhaps "mispriced" but far from a "clear and obvious" error.

1st Q Sweats also had his bet voided:

"Got voided here too. Where’s the line? They can void whatever the hell they want, and do it 7 hours later? If you arbbed elsewhere you’re out of luck. ProphetX can decide what to void whenever it wants to based on how valuable the market maker is to them."

Gambling911.com will continue to monitor this situation.  Prophet X was yet to comment.
