Full prediction
Within 30 days, Taiwan’s decision to hike its 2027 defense budget by 18% is likely to be followed by new or expanded U.S. arms-sale announcements focused on drones, missiles, and force-modernization packages, prompting sharper Chinese military signaling around the island. PLA aircraft and ship incursions into Taiwan’s ADIZ and across the median line are likely to rise, and Beijing may stage a focused exercise to underscore its displeasure. This dynamic will lock in multi-year demand for U.S. and allied defense suppliers while increasing the baseline risk of an incident in the Taiwan Strait. Confirmation would be new notified sales or cooperation frameworks plus visible PLA drills; denial would be an unexpected pause or scaling back of U.S. security support and muted PLA reaction.
