SMCI Dark Pool Data — Block Trades, Dark Pool Prints & POC Levels

SMCI's off-exchange volume share of roughly 46% places it well above the US equity average of approximately 38-40%, and far above highly liquid mega-caps like NVDA at 19% or AAPL at 22%. The explanation is straightforward: SMCI is a structurally less liquid stock than those names — its float is roughly 65 million shares post-dilution, compared to NVDA's 24 billion share equivalent float — so institutions executing million-dollar-plus positions have a stronger incentive to use dark pools to avoid moving the price. In my tracking of SMCI dark pool prints from January through May 2026, the largest single off-exchange print I cataloged was a 5.36-million-share block on May 26, 2026 at $40.64, representing roughly $218 million in notional value executed in a single trade. To put that in perspective: that one dark print was equivalent to roughly 8% of SMCI's entire daily volume that day. The average SMCI dark pool block during those five months was 42,500 shares — smaller than NVDA's average but larger than most mid-cap AI stocks, reflecting the tiered nature of institutional participation in this name.

The NBBO direction classification of SMCI dark pool prints tells a story about institutional positioning through the most volatile six months in this stock's history. Between January and March 2026, Above Ask prints (buyer-initiated) accounted for 44% of SMCI dark pool volume, Below Bid (seller-initiated) for 40%, and mid-point crosses for 16%. After the March 19 selloff, the Below Bid share jumped to 52% over the following five sessions — a clear institutional distribution response to the DOJ news. By late April, as the equity financing structure was announced, Above Ask prints recovered to 49%, suggesting institutional buyers stepping in to absorb the dilution. In May, after the earnings beat, Above Ask prints hit 55% — the highest reading I have recorded for SMCI since I began tracking its dark pool prints in early 2025. The single most aggressive Below Bid print I cataloged was a 1.2-million-share block on March 20 at $23.10, with the National Best Bid at $23.45 — a 35-cent concession confirming aggressive institutional selling at any available price. Contrast that with a 950,000-share Above Ask print on May 6 at $33.80, with the National Best Offer at $33.75, where the buyer paid a 5-cent premium for immediate access to 33 million dollars' worth of stock.
