The firm behind a failed plan to build a £433m race track in Blaenau Gwent has lost the rights to hold the MotoGP.
Circuit of Wales signed a 10-year deal three years ago to hold the motorbike race at its proposed track in Rassau, Ebbw Vale.
But in June the Welsh Government refused to provide £210m of taxpayer-funded guarantees on the project.
Circuit of Wales said the decision by MotoGP organisers Dorna to end its relationship was "understandable".
The three-day MotoGP has been held at Silverstone for the past three years and the race track will host this year's event from August 25 to 27.
