On Wednesday, the Big Four—Microsoft, Google, Amazon, and Meta—will release their earnings reports. Meta is expected to deliver the most positive surprise, as its ad + AI flywheel has been validated and consistently exceeded expectations by the widest margin. Google has the strongest fundamentals, with explosive growth in its cloud business, though expectations are already quite high. Amazon's focus will be on AWS growth and retail guidance, making it the most variable with the largest two-way swings. Microsoft is the riskiest of the four—if Azure slightly underperforms, the market will punish it, but if it beats expectations, the rebound potential is also the highest.
