The first half of 2026 handed investors a split-screen market. The Dow rose roughly 8% in the first half of 2026, while the Nasdaq-100 gained about 26% in Q2, powered almost entirely by the AI infrastructure trade. The question now is which names have the fundamental firepower to keep compounding into the back half. Growth rates north of 40%, AI revenue lines doubling year over year, and management teams raising guidance are the filter. Three stocks clear that bar with room to spare.
Below is the countdown of the top three AI stocks positioned to keep running, ranked by AI momentum, guidance trajectory, and scale.
#3. Palantir
Palantir (NASDAQ:PLTR | PLTR Price Prediction) has the growth profile of a company at least twice its size. In Q1 2026, revenue jumped 85% year over year to $1.63 billion, U.S. commercial revenue surged 133% to $595 million, and adjusted EPS of $0.33 beat consensus by 18% for the eighth consecutive quarter. CEO Alex Karp raised full-year guidance to 71% growth, 10 points ahead of the prior guide, and touted a Rule of 40 score of 145%.
The bull case rests on that Rule of 40 print. Karp said “Palantir’s Rule of 40 score has soared to 145%. We have shattered the metric… we grew 85% last quarter, our highest-ever year-over-year growth rate, by more than doubling our U.S. business.” AIP adoption is compounding, and U.S. commercial remaining deal value hit $4.92 billion, up 112% year over year.
The caveat is valuation. Shares carry a trailing P/E near 131 and a forward P/E of 80, and the stock is down about 29% year to date through July 1, a reset that must hold if fundamentals catch up to the multiple.
#2. AMD
Advanced Micro Devices (NASDAQ:AMD) is the momentum leader. Shares are up roughly 153% year to date through July 1, backed by strong fundamentals. Q1 2026 revenue reached $10.25 billion, up 38% year over year, with Data Center growing 57% to $5.78 billion. Adjusted EPS of $1.37 beat by nearly 6%, and free cash flow exploded 253% to $2.57 billion.
Q2 guidance calls for roughly $11.2 billion in revenue, implying about 46% growth, alongside gross margin widening to around 56%. Lisa Su said “Customer engagement around MI450 Series and Helios is strengthening, with leading customer forecasts exceeding our initial expectations.” Signed deployments include up to 6 gigawatts of Instinct GPUs with Meta and a similar-scale OpenAI commitment.
The risk is valuation. AMD trades at a trailing P/E of 182 and forward P/E of 77, with a beta of 2.49. Any MI450 ramp delays would sting.
#1. Broadcom
Broadcom (NASDAQ:AVGO) tops the list because scale plus acceleration is rare at a $1.75 trillion market cap. Q2 FY2026 revenue hit $22.19 billion, up 48% year over year, with AI semiconductor revenue reaching $10.80 billion, up 143%. Operating income jumped 85% to $10.79 billion, free cash flow rose 60% to $10.26 billion, and adjusted EBITDA margin sat at 69% of revenue.
The forward number is the kicker. Broadcom guided Q3 total revenue to roughly $29.4 billion, up 84%, with AI semiconductor revenue projected to grow over 200% year over year to $16.0 billion. CEO Hock Tan said “The momentum continues and in Q3 we expect semiconductor revenue from AI to grow over 200 percent year-over-year to $16.0 billion.” Management’s stated ambition is to exceed $100 billion in AI sales by 2027. Wall Street is aligned, with 44 buy ratings versus 4 holds and no sells, and an analyst target of $523.73.
The caveat: Broadcom is up only about 7% year to date through July 1, and shares fell roughly 20% over the past month, a reminder that even the cleanest AI story faces profit-taking. Seventy-one recent insider transactions skew net selling, worth watching alongside the Q3 earnings report.
Why the Rally Has Room
H1 2026’s 8% Dow and 26% Nasdaq-100 Q2 gain were just the opening leg of a longer trade. Palantir’s 85% growth and raised guide, AMD’s 46% Q2 revenue outlook and MI450 pipeline, and Broadcom’s $16 billion AI quarter all point in the same direction: second-half AI numbers are getting bigger. Broadcom lands at #1 because it is delivering triple-digit AI growth at trillion-dollar scale, a combination that historically re-rates rather than fades. Keep an eye on the Q3 earnings report in early September for confirmation.
