Quantum Blockchain Technologies (QBT) said its 16 April 2026 RNS reported that a share placing raised £500,000 before expenses through the issue of 142,857,142 new ordinary shares at 0.35 pence each.
The company said the net proceeds will support continued research and development aimed at improving Bitcoin mining efficiency, as well as work needed to port its AI Oracle onto mining rigs from new ASIC manufacturers.
QBT added that it will apply for the placing shares to be admitted to AIM on or around 21 April 2026. The filing also stated that the announcement contained inside information under Article 7 of the UK Market Abuse Regulation regime.
QBT said BlocKeeper is being built as a hardware-free Bitcoin virtual mining operation. Under the plan, BlocKeeper would selectively acquire hashing power from established miners, separating the mining venture from QBT’s parent company software-focused work.
The company said it may invest up to £100,000 into BlocKeeper, or 20% of the gross raise, as a seed commitment for the subsidiary.
QBT also said BlocKeeper is seeking a listing on the AQSE Stock Exchange Growth Market, while warning there is no certainty that the proposed listing will occur.
Because the BlocKeeper allocation is capped at up to £100,000, with the remainder of the placing proceeds directed to Bitcoin-mining R&D and AI Oracle porting work, the current plan is framed as an initial test of virtual mining rather than a full shift away from QBT’s existing technology program.
QBT’s disclosed structure keeps the parent company funding its software and optimisation program, while BlocKeeper would begin as a smaller vehicle that buys external hashing power instead of owning hardware.
Investors highlighted in the announcement face two specific milestones: the target 21 April 2026 admission date for the placing shares, and the still-uncertain plan for BlocKeeper’s listing on the AQSE Growth Market.
QBT’s approach, as described in the filing, is structural rather than promotional. The company chose a ring-fenced subsidiary and a capped initial commitment, and the RNS did not set out projected hash rate, revenue, or profitability for BlocKeeper.
QBT said the placing raised £500,000 before expenses.
BlocKeeper is the new subsidiary QBT described as a hardware-free Bitcoin virtual mining operation that would buy hashing power from established miners.
The filing indicates the placing funds continued mining R&D, AI Oracle porting work, and the initial BlocKeeper rollout, without describing any debt financing alongside the move.
QBT said BlocKeeper would selectively acquire hashing power from established miners rather than build and run its own rig fleet.

Premium gym chains are entering a “golden era” that is ending or already in decline, as rising operating costs collide with shifting consumer preferences toward more flexible, community-based ways to exercise. Long-term memberships are shrinking, margins are pressured by higher rents and facility expenses, and competition from smaller, more personalized…
