The scenario does not change the expected Allied victory, but heavier carrier losses at Midway would delay the next Pacific offensives. If both sides lost roughly two carriers and entered repair periods, neither would hold easy control of the sea, making a rapid American advance less likely. Without an immediate Guadalcanal campaign, the US Navy would preserve more destroyers and cruisers for later fighting around Australia. The Mediterranean and North Atlantic campaigns would also advance further before those Pacific battles, potentially freeing a larger British naval contribution. This is a change in timing and force availability within the scenario, not a claim that Japan wins the war.

An even Midway could delay Guadalcanal and enlarge British involvement
Heavier carrier losses at Midway could postpone Guadalcanal, preserve American cruisers and destroyers for later battles, and give Britain more time to reinforce the Pacific.
