The race to the market cap superiority is on and both Alphabet (NASDAQ: GOOG) and Nvidia (NASDAQ: NVDA) are ahead in line. While Nvidia’s market cap is approximately $5.34 trillion, Alphabet’s is at $4.66 trillion. They are just at the doorstep of reaching $6 trillion and $5 trillion, respectively. On the heels of the ongoing Google I/O 2026 event, Alphabet stock is gearing up to touch the $5 trillion market cap milestone.

The timing for Alphabet stock to climb above $5 trillion in market cap remains ripe with the Google I/O 2026. The valuation could soar after the event if Google’s stock goes beyond the $415 price threshold. In addition, the upcoming string of AI releases could also solidify its stance and break the $5 trillion price ceiling. The roll-outs are scheduled until September, which can make or break GOOG in the charts.

The chances of Alphabet stock reaching a market cap of $5 trillion after the Google I/O 2026 are high. Considering that GOOG hit a 52-week high of $408.61 in early May and retraced in price, a repeat of this level could push it again close to the milestone. GOOG is consolidating at the $380 to $390 level, and could experience a breakout with the $462 backlog. Taking an entry position below $400 could be the best bet for the long term.

To keep it precise, if Google stock hits a price of $413 to $415, it can breach the $5 trillion club. Whether that will happen during the Google I/O 2026 or come later on, it is very close to meeting the magic number. A flurry of new investments could pour into Alphabet if it climbs above the target. The move could inadvertently make GOOG surge further in value, and now could be the best time to accumulate it.
