BlackBerry Ltd. (BB), Sidus Space Inc. (SIDU), and Rigetti Computing Inc. (RGTI) were among the week’s biggest stock movers as investors rotated into artificial intelligence, quantum computing, and space-related names. BlackBerry surged after executives framed the company’s recent results as evidence of a new growth phase. At the CIBC Technology & Innovation Conference 2026, CFO Tim Foote said BlackBerry has shifted from a cash-burning business to a profitable software company, with eight consecutive quarters of improving GAAP net income and positive cash generation. QNX business President John Wall also highlighted expansion opportunities beyond automotive, including robotics, industrial automation, and physical AI applications that require higher-performance computing. BlackBerry’s Secure Communications segment also gained support after BlackBerry AtHoc completed its 2026 FedRAMP Class D (High) re-certification, and the company renewed its share buyback program through May 2027. BB shares have more than doubled this year, and retail sentiment on Stocktwits moved to “extremely bullish” amid elevated message volume.
Sidus Space extended its rally after posting strong first-quarter 2026 results. The company reported revenue growth of about 51% year over year to $359,372, while its net loss narrowed to $5.21 million from $6.41 million a year earlier. Investors also responded positively to Sidus’ improved balance sheet, which was boosted by a $58.5 million registered direct offering completed in April. The company ended the quarter with roughly $27.35 million in cash and no debt, reducing near-term financing concerns that had previously pressured the stock. Broader enthusiasm for the space sector also helped the move, with traders betting on satellite, defense, and space infrastructure companies as speculation grew around a possible SpaceX IPO expected in June. SIDU shares have climbed about 239% over the past year, and analysts tracked by Koyfin see additional upside from current levels. Stocktwits sentiment remained bullish with high message volume.
Rigetti Computing also advanced after the Trump administration announced $100 million in grants for the company as part of a broader effort to strengthen the U.S. quantum computing industry. The funding, to be delivered over three years under the CHIPS Act through the U.S. Department of Commerce, is intended to help Rigetti address technical challenges tied to scaling superconducting quantum systems. The company said the capital will support development of next-generation cryostat architectures and the miniaturization and integration of advanced readout electronics. RGTI shares have risen more than 86% over the past year, and retail sentiment on Stocktwits was “extremely bullish” on very high message volume.
