Quantum Blockchain Raises £500,000, Launches Bitcoin Mining Unit BlocKeeper

Quantum Blockchain Technologies said it raised £500,000 before expenses through a share placement and used the same announcement to launch BlocKeeper, a hardware-free Bitcoin mining subsidiary that would buy third-party hashing power instead of operating its own rigs.

Quantum Blockchain raises £500,000 through share placement

In its 16 April 2026 RNS, QBT said the placing raised £500,000 before expenses through the issue of 142,857,142 new ordinary shares at 0.35 pence each.

Gross placing proceeds

£500,000

QBT said the net proceeds will support continued research and development aimed at improving Bitcoin mining efficiency and the work needed to port its AI Oracle onto mining rigs from new ASIC manufacturers.

The company added that it will apply for the placing shares to be admitted to AIM on or around 21 April 2026, and the filing said the announcement contained inside information under Article 7 of the UK Market Abuse Regulation regime.

Why BlocKeeper matters to Quantum Blockchain’s Bitcoin mining strategy

QBT said BlocKeeper is being built as a hardware-free Bitcoin virtual mining operation that will selectively acquire hashing power from established miners, which separates the mining venture from the parent company’s software-focused work.

QBT said it may invest up to £100,000 into BlocKeeper, or 20% of the gross raise, as the seed commitment for the subsidiary.

Planned BlocKeeper investment

£100,000

Potential seed commitment equal to 20% of the gross placing proceeds.

The RNS also said BlocKeeper is seeking a listing on the AQSE Stock Exchange Growth Market, while warning there is no certainty the proposed listing will occur.

How the fundraising and subsidiary launch fit together

Because the filing limits the BlocKeeper allocation to up to £100,000 and leaves the rest of the placing proceeds for Bitcoin-mining R&D and AI Oracle porting work, the current plan reads as a limited test of virtual mining rather than a full-company shift away from QBT’s existing technology program.

That interpretation rests on the structure QBT disclosed in the same filing: the parent company keeps funding its software and optimisation program, while BlocKeeper starts as a smaller vehicle that would buy external hashing power instead of owning hardware.

Investors therefore have two specific milestones from the announcement to watch: the target 21 April 2026 admission date for the placing shares and the still-uncertain AQSE Growth Market plan for the subsidiary.

What this move signals for Bitcoin mining and blockchain investors

For blockchain investors, the more relevant signal is structural than promotional: QBT chose a ring-fenced subsidiary and a capped initial commitment instead of promising a large-scale mining rollout, and the RNS does not set out projected hash rate, revenue, or profitability for BlocKeeper.

That makes the announcement part of a broader digital-asset business story in which market access and business-model design matter alongside token prices, a theme Coincu readers have also seen in coverage of a NYSE rule change proposal that could open door to tokenized securities trading, the rise of Spartans reaching the 14th largest crypto casino, and Spartans Casino hitting rank 14 globally while Yeet and Sol Casino stayed more limited.
