Grid Dynamics Stock Surges 41% on Record Quarter as AI Revenue Hits 31%

Grid Dynamics (NASDAQ: GDYN) closed up 40.68% at $13.37 on Friday, October 30, 2026 — one of the biggest gains in the entire U.S. market on a day the Nasdaq fell about 4% — after the digital engineering company reported record third-quarter revenue of $114.3 million, record AI revenue at 31% of the total, and fourth-quarter guidance ahead of Wall Street expectations.

What happened

Grid Dynamics reported its third-quarter 2026 results after the close on Thursday, October 29. Revenue came in at $114.3 million, above the high end of the company's own guidance range of $112.0 million to $114.0 million and ahead of analyst estimates of about $112.7 million. Revenue rose 9.7% from a year earlier.

Profit beat by a wider margin. Adjusted earnings were $0.18 per share, up from $0.09 a year earlier and well ahead of the $0.13 consensus. Adjusted EBITDA reached $22.9 million, surpassing expectations of about $16.81 million, while operating margin expanded to 8%, up from negative 0.2% a year ago.

The stock jumped 24.5% in the morning session and kept climbing, closing at $13.37, up $3.87 from its previous close of $9.49, on volume of about 8.52 million shares. The close set a new 52-week high and made Grid Dynamics the third-biggest gainer in the U.S. market for the session, behind only two much smaller names that more than doubled.

Why it is blowing up

The headline inside the headline was AI. The company's release was titled for record AI revenues of 31% — meaning nearly a third of Grid Dynamics' business now comes from AI work for Fortune 1000 clients, at a moment when investors spent Friday punishing other technology names over doubts that heavy AI spending will pay off. Grid Dynamics is on the other side of that trade: it sells the engineering work that helps large companies put AI into production.

Growth was led by its Technology, Media and Telecom vertical, which represented 32.3% of third-quarter revenue. That vertical's revenue increased 29.3% year over year and 7.6% sequentially, and the company described it as its principal growth driver for the quarter.

The guidance added fuel. For the fourth quarter, Grid Dynamics guided revenue to between $113.5 million and $115.5 million and non-GAAP EBITDA to between $20.0 million and $22.0 million. At the midpoints, both figures — $114.5 million of revenue and $21.0 million of EBITDA — exceeded analyst projections of $112.8 million and $17.45 million respectively. Needham also raised its price target on the stock to $15 from $10 while keeping a Buy rating, according to MarketBeat's analyst tracker.

The contrast with the rest of the market

Friday was a rout for technology stocks. The Nasdaq Composite fell about 4% and the S&P 500 fell about 2.1%, as Intel plunged around 29% to 30% on a weak outlook and Amazon slid after missing expectations and reporting a sharp fall in free cash flow amid massive AI spending. Chip stocks fell across the board. Against that tape, a small-cap engineering firm closing up more than 40% on record results and a guidance raise stood out sharply — and it did so on heavy volume, not a thin move.

What is next

The next test is whether Grid Dynamics can deliver the fourth quarter it just promised — revenue near $114.5 million at the midpoint — and keep AI work growing as a share of the total. Investors will also watch whether the Technology, Media and Telecom vertical can sustain anything close to its 29.3% growth rate. Friday's move repriced the stock to a new 52-week high in a single session, so expectations are now materially higher than they were on Thursday.
