An experimental portfolio managed by Grok, the artificial intelligence (AI) system developed by xAI, has been delivering substantial financial results.

Between May 14 and August 13, 2025, the SPDR S&P 500 ETF Trust (SPY), for example, climbed from $587.59 to $644.89, benefiting from broad strength in technology and consumer stocks. 

Grok’s 15-stock portfolio, however, managed to deliver stronger results, driven by standout performances in AI, cloud computing, and payment processing sectors. 

All in all, the so-called “financial advisor” generated a 12.6% return, 2.85% higher compared to the 9.75% gain reported by SPY over the same time period.

Grok stock picks

Oracle (NYSE: ORCL) was Grok’s most successful pick, surging 49.9% after a strong cloud earnings beat. Similarly, Nvidia (NASDAQ: NVDA) rose 34.2% as demand for its semiconductor chips remained dominant in the second quarter. 

Broadcom (NASDAQ: AVGO) also gained 33.2% thanks to booming AI networking demand, while Mastercard (NYSE: MA) surged 21.7% as global payments volume and travel spending increased.

Of course, not all stocks delivered. For instance, Eli Lilly (NYSE: LLY) fell 7.7% as biotech momentum slowed, and Lockheed Martin (NYSE: LMT) declined 4.2% amid weakness in the defense sector. 

The portfolio’s overall performance was thus mostly a result of its insistence on AI and computing software solutions, additionally bolstered by strength in payments and cloud services. 

Some exchange-traded fund (ETF) positions, such as Technology Select Sector SPDR Fund (XLK), Consumer Staples Select Sector SPDR Fund (XLP), and iShares 20+ Year Treasury Bond ETF (TLT), also helped limit volatility.
