KPI #6 — $31 Million in Bets Says No Invasion This Year
Prediction Market Implied Probability
What it measures: The real-money probability assigned by open prediction markets to a Chinese invasion of Taiwan within a defined time horizon.
Prediction markets are not polls. They are aggregators of informed, financially incentivised opinion. When a trader buys a “Yes” share on “Will China invade Taiwan by end of 2026?” at a price of 4 cents, they are staking real money on a 4% probability. The market price at any given moment reflects the collective assessment of thousands of participants, including analysts, investors, and people with access to non-public information.
As of May 2026, $31.4 million has been traded on the end-of-2026 question on Polymarket. The market assigns this event a probability below 5%. That is a green signal. But the same market infrastructure assigns approximately 37% probability to an invasion before 2030 — which is a very different number.
The gap between “not this year” and “within four years” is where the strategic planning challenge lives.
Current status: 🟢 Green for 2026. 🟡 Amber for the 2027–2030 window. Markets are probably right about this year. They are less reassuring about the decade.

KPI #7 — China’s Achilles Heel. The oil routes and soya supply lines that make a Chinese invasion economically catastrophic for Beijing — and why this deterrent is slowly eroding.
⚡ The consequence to watch
When prediction markets cross 10% for a current-year invasion, financial markets typically begin pricing in risk premiums on Taiwan-exposed equities. That re-pricing would happen before any military action — your window to act is when markets are at 8%, not when they are at 25%.
🔧 The drill
Bookmark polymarket.com and manifold.markets and check the Taiwan invasion markets monthly. Set a calendar reminder. If either market crosses 10% for the current year, that is your trigger for an internal risk review — regardless of what the news is saying.
