Greece Politics Explained, Who Holds Power in 2026

Who Holds Power

Greece is a parliamentary republic in which the prime minister, not the president, directs the government and holds the most significant political authority. Prime Minister Kyriakos Mitsotakis, leader of the conservative New Democracy party, remains in office as of October 24, 2026.

President Konstantinos Tasoulas, elected by Parliament in February 2025, serves as head of state for a five-year term. The 300-member Hellenic Parliament elects the president and holds legislative power alongside the government.

New Democracy governs alone and wants to keep a single-party majority at the next election. A poll in the Attica region around Athens found 47.8% of respondents favouring a one-party government.

The main challenger is now Alexis Tsipras, the former prime minister, who founded a new left-wing party, ELAS, in May 2026. Recent polls put New Democracy at about 30% to 31%, with ELAS second at about 16% to 17% and the socialist PASOK third.

SYRIZA, Tsipras’s old party, has shrunk to about 2% in one Athens-area poll. Its secretary, Nikos Pappas, urged young people on October 19 to join protests, calling them “oxygen for society.”

The Election Contest and the Economy

Parliamentary elections must take place by July 2027, and the central question is whether New Democracy can keep its absolute majority. Mitsotakis said in May 2026 that the vote will be held in 2027.

S&P Global Ratings affirmed Greece at BBB/A-2 with a stable outlook on Friday, October 23. It expects a primary budget surplus, the balance before interest payments, of 3.8% of GDP in 2026 and an average of 3.2% in 2027–29.

Three Policy Fights

Energy costs remain a central issue, and the government has expanded support for households this autumn, including a heating allowance of up to €1,500 (about US$1,680) for around 1.2 million households. It also announced a discount of 40 cents per litre on heating oil.

Migration is a second dividing line. Greece has proposed an EU emergency mechanism that would let frontline states suspend asylum applications, initially for up to 30 days, in a mass-arrival crisis like the 2020 Evros border crisis, and Greek media report that the European Commission has backed the plan.

The mechanism is not yet law. On October 15, Minister Michalis Chrysochoidis announced a ban on renting out overcrowded flats in central Athens, where 20 to 30 migrants sleep for €10 to €30 (about US$11 to US$34) a night.

European funding is the third major fight. Greece is pressing in Brussels against cuts to Cohesion Policy and the Common Agricultural Policy, and it hosted a meeting of the “Friends of Cohesion” group of EU states on September 21.

EU, NATO and Russia

Greece is a member of both the European Union and NATO. Its government is engaged in EU negotiations over migration, cohesion funding and agricultural policy.

What Prediction Markets Say

On Polymarket, where US$33,004 has been traded, Mitsotakis stands at 64.0% to be the next prime minister, ahead of Alexis Tsipras at 7.1% and Nikos Androulakis at 2.1%. Kalshi, a market regulated in the US by the CFTC, gives Mitsotakis 73%, with 12,298 contracts traded.

A separate Polymarket market gives a 7.5% chance that a snap election is scheduled in 2026. These prices are bets, not polls, and they were read on 24 October at 5:30 a.m. ET.

Why we show this: prediction markets turn real-money bets into a live probability that moves within minutes of the news, which is why investors, campaigns and newsrooms in the United States now follow them closely. We show them next to polls and official results, never instead of them.

What It Means for US Readers

For US readers, Greece’s political stability matters for NATO’s southeastern flank and for American travel and investment in the Eastern Mediterranean. A fragmented parliament after 2027 could slow decision-making on migration and defence cooperation.

US investors in Greek bonds will note S&P’s stable outlook of October 23. Greece’s primary surplus is projected at 3.8% of GDP in 2026.

What Is Not Known

It is not known whether New Democracy can keep its absolute majority; polls put it at about 30% to 31%, but seat projections vary. Who would govern if it falls short is also unclear.

The legal text and final approval of the proposed migration mechanism and the housing ban are not settled. The Commission’s backing of the migration plan is not a binding decision.

The exact election date is not set, only that it is due by July 2027. A snap election is possible, though Mitsotakis has pointed to 2027.

Euro amounts in this guide use US$1.12 per euro, the market rate on October 24. They are rounded.
