What happens in a Kenyan presidential runoff

Short answerIf no presidential candidate wins more than 50% of the vote and 25% in at least 24 counties, a fresh election between the top two candidates is held within 30 days. The candidate with more votes in the runoff is declared president. No Kenyan presidential election has yet gone to a constitutional runoff.

Who takes part?

Only the two candidates with the most votes in the first round. All others drop out.

When is it held?

Within 30 days of the first election, according to the Constitution (Article 138).

Who wins?

The candidate who gets the most votes in the runoff is declared president-elect.

Has Kenya had one?

No presidential election has gone to a constitutional runoff so far. In 2017 the Supreme Court annulled the August result and ordered a fresh election, held on 26 October 2017. That was a re-run after a court ruling, not a runoff under the 50% rule.

What if the result is challenged?

A petition must be filed at the Supreme Court within seven days of the declaration. The court has 14 days to decide. If it nullifies the election, a fresh election must be held within 60 days.

How likely is a runoff in 2027?

In the latest poll (Infotrak July 2026) the front-runner, William Ruto, is on 32%, well short of 50%, so a runoff is a real possibility. Polls this far out are a snapshot, and alliances can change a race quickly. Follow the poll tracker for updates.
