<P> In the case of 2018 Semifinals games, winner and loser columns only denote rank . These games have yet to be played and a winner has yet to be determined . </P> <P> Cities around the country bid to host each year's championship game . The playoff group's leaders make a selection from those proposals, in a similar fashion to other large sporting events, such as the Super Bowl or NCAA Final Four . Officials say the championship game will be held in a different city each year, and that bids must propose host stadiums with a capacity of at least 65,000 spectators . Under the system, cities cannot host both a semifinal game and the title game in the same year . </P> <Table> <Tr> <Th> Season </Th> <Th> Champion </Th> <Th> Runner - up </Th> <Th> Score </Th> <Th> Venue </Th> </Tr> <Tr> <Td> 2014--15 </Td> <Td> 4 Ohio State </Td> <Td> 2 Oregon </Td> <Td> 42--20 </Td> <Td> AT&T Stadium, Arlington, Texas </Td> </Tr> <Tr> <Td> 2015--16 </Td> <Td> 2 Alabama </Td> <Td> 1 Clemson </Td> <Td> 45--40 </Td> <Td> University of Phoenix Stadium, Glendale, Arizona </Td> </Tr> <Tr> <Td> 2016--17 </Td> <Td> 2 Clemson </Td> <Td> 1 Alabama </Td> <Td> 35--31 </Td> <Td> Raymond James Stadium, Tampa, Florida </Td> </Tr> <Tr> <Td> 2017--18 </Td> <Td> </Td> <Td> </Td> <Td> </Td> <Td> Mercedes - Benz Stadium, Atlanta, Georgia </Td> </Tr> <Tr> <Td> 2018--19 </Td> <Td> </Td> <Td> </Td> <Td> </Td> <Td> Levi's Stadium, Santa Clara, California </Td> </Tr> <Tr> <Td> 2019--20 </Td> <Td> </Td> <Td> </Td> <Td> </Td> <Td> Mercedes - Benz Superdome, New Orleans, Louisiana </Td> </Tr> <Tr> <Td> 2020--21 </Td> <Td> </Td> <Td> </Td> <Td> </Td> <Td> Hard Rock Stadium, Miami Gardens, Florida </Td> </Tr> <Tr> <Td> 2021--22 </Td> <Td> </Td> <Td> </Td> <Td> </Td> <Td> Lucas Oil Stadium, Indianapolis, Indiana </Td> </Tr> <Tr> <Td> 2022--23 </Td> <Td> </Td> <Td> </Td> <Td> </Td> <Td> Los Angeles Stadium at Hollywood Park, Inglewood, California </Td> </Tr> <Tr> <Td> 2023--24 </Td> <Td> </Td> <Td> </Td> <Td> </Td> <Td> NRG Stadium, Houston, Texas </Td> </Tr> </Table> <Tr> <Th> Season </Th> <Th> Champion </Th> <Th> Runner - up </Th> <Th> Score </Th> <Th> Venue </Th> </Tr>
