Japan heads to the polls on Sunday, Feb. 8, and Polymarket traders are pricing in a near-lock: Prime Minister Sanae Takaichi is staying in power.

Why it matters: 

Markets are trading on the expectation of aggressive policy continuity—massive fiscal stimulus, a slower path to interest rate hikes from the Bank of Japan, and a significantly tougher security posture. The yen has been trading heavy ahead of the vote, with USD/JPY hovering near the 157 level.

What Polymarket is Signaling

• Prime Minister after the snap election: Takaichi 99%
• Governing parties market: LDP 99%, but JIP only 22%

Traders are effectively betting on a “Supermajority” scenario. The low 22% probability for the JIP (Japan Innovation Party) suggests a market view that the LDP may not even need its coalition partner to govern. This would give Takaichi a “clear runway” to implement her most hawkish policies without legislative horse-trading.

Trump Jumps In

U.S. President Donald Trump publicly endorsed Takaichi on Truth Social this week—a rare intervention in the election of a G7 ally. Trump called her a “strong, powerful, and wise leader” and confirmed he will host her at the White House on March 19.

The ‘Takaichi Trade’ Watchlist

The Takaichi platform is read by markets as reflationary and security-centric. With the Cabinet already signing off on a record ¥9.04 trillion ($58 billion) defense budget for FY2026, the procurement cycle is front and center.

U.S. Primes with Japan Exposure:

Lockheed Martin Corp (NYSE:LMT), RTX Corp (NYSE:RTX), Northrop Grumman Corp (NYSE:NOC)

Japanese Defense-Linked Names:

Mitsubishi Heavy Industries (OTC:MHVYF), Kawasaki Heavy Industries (OTC:KWHIY), Mitsubishi Electric (OTC:MIELY)

The Risk: ‘Triple Dip’ Narrative

Some analysts strike a note of caution, however, warning that a “triple dip” scenario could be triggered if fiscal overreach destabilizes the yen carry trade.
If investors decide Takaichi's “Sanaenomics” stimulus threatens fiscal sustainability, Japan could face a “Triple Dip”: stocks down, bonds down, and the yen breaking past 160.
