Oval Invincibles

The announcement of the new eight-team men's and women's tournament series in 2019 was not without controversy, with the likes of Virat Kohli criticising the England and Wales Cricket Board for pursuing a shift away from Test cricket, while others argued the format should have followed the established and successful Twenty20 format. The ECB however decided it needed a more unique format to draw crowds.

In August 2019, the side announced that Australian coach Tom Moody would be the men's team's first coach, while former England Women player Lydia Greenway was appointed coach of the Women's team.

The inaugural Hundred draft took place in October 2019 and saw the Invincibles claim Sam Curran as their headline men's draftee, and Laura Marsh as the women's headliner. They were joined by England internationals Tom Curran and Jason Roy for the men's team, while Fran Wilson joined Marsh in the women's side.

In 2024, Reliance Industries Limited, the owner of the Mumbai Indians Indian Premier League franchise, purchased the English Cricket Board's 49% stake in the Invincibles for about £60 million, valuing the franchise at around £120–125 million. Surrey retain the remaining 51% and therefore majority control.

For RIL, the purchase adds to their "MI" portfolio, which already includes teams in India, South Africa, the UAE, and the US.

Reports suggest that from the 2026 season the Invincibles may be rebranded as MI London, aligning with Reliance’s strategy of creating a global MI cricket network.
