AI Data Centre Boom Delivers 166.5% Fund Return as Former Bitcoin Miners Lead Charge

For AI builders and operators, the story behind Tectonic's 166.5 per cent return is about the physical layer powering the intelligence revolution—data centres with huge power capacity and existing cooling once used for SHA-256 hashing are now the hottest real estate in AI. This convergence of compute infrastructure is creating entirely new asset classes and return profiles.

A boutique investment firm from Kingscliff, Australia, Tectonic Investment Management, has stormed to the top of the nation's equity fund rankings, delivering a 166.5 per cent return for the 2026 financial year. The previously low-profile manager's Opportunities Fund more than doubled investor capital, handily beating its peers in a volatile market and underscoring the enormous wealth that has accrued to those who positioned early for the artificial intelligence infrastructure boom. The performance was driven not by traditional tech names but by two former bitcoin miners—Firmus and Nasdaq-listed IREN (formerly Iris Energy)—that have successfully pivoted to supplying data centre capacity for AI workloads. Investment chief Ben Haan acknowledged an element of luck, particularly with Firmus, but stressed that the real skill was holding the positions. 'What we’ve done well is not taking money off the table too soon,' he said. The position in Firmus, first acquired in 2021, is now valued at 45 times its initial cost, a staggering multiple that reflects the repricing of assets once dedicated to cryptocurrency mining that are now seen as critical AI infrastructure.

Tectonic's result did not occur in isolation. The convergence of bitcoin mining and AI data centres has become one of the most potent themes in global equity markets. Former mining operations possess large-scale power access, cooling infrastructure, and custom-built facilities that are proving perfectly suited to the compute-intensive demands of large language models and other AI workloads. IREN, for example, has redirected its Nasdaq-listed enterprise from pure bitcoin mining to a broader high-performance computing and AI cloud services model. This pivot has captured the imagination of investors seeking exposure to the AI supply chain beyond chipmakers like Nvidia. The returns generated by Tectonic highlight how a concentrated bet on this thematic crossover can produce venture-capital-like outcomes within a listed equities framework.

Other top-performing funds in the FY2026 Fund Monitors rankings also posted eye-catching numbers, though none approached Tectonic's stratospheric result. Sydney-based hedge fund Paragon secured second place with a 92.9 per cent return, despite headwinds in precious metals, where the fund often has exposure. Terra Capital's Green Metals Fund, an ESG-focused strategy that avoids traditional fossil-fuel and gold investments, took third with a 90.2 per cent gain. Its portfolio manager, Matthew Langsford, noted that the critical minerals segment—essential for electrification and batteries—remained particularly interesting. Brisbane's Sharpbridge Funds Management recorded a 78.6 per cent return in its global equities strategy, while Melbourne's L1 Capital and Perth's Argonaut Funds Management both rode gold-related plays into the top ten, demonstrating that strong returns could be found in a variety of commodities and mining exposures as well.
