Did someone insider trade Zach XPT's insider trading investigation?

You're watching Coin Desk Daily. I'm Jen Sanassi.

A polymarket prediction market on which crypto firm Zach XPT would accuse of insider trading saw about $40 million in volume before he named Axiom as the target on chain analysts, say a small cluster of newly created wallets, but heavily on Axiom just before the reveal, generating more than $1 million in profit and suggesting someone had advanced knowledge.

Because Pollymarket does not require identity checks and Axiom employees did know of the

investigation ahead of publication, any potential insider betting may be difficult to trace,

even as Axiom says it is investigating. Mara Holdings jumped 16% after striking a deal with

Starwood Capital to convert Bitcoin mining facilities into AI data centers. The partners aim to

deliver one gigawatt of capacity following the industry trend of miners monetizing their power

access for AI computing. On the fintech side, Block surged 20% after announcing it will cut 40% of

its workforce, leaning into AI-driven efficiencies to boost margins. But it wasn't all green. Core

Weave shares fell 12 percent despite beating revenue expectations as concerns over high cash burn

and capital expenditures spooked investors. Similarly, Terra Wolf dipped 3.5 percent on a revenue

miss, though executives remain bullish on their own high-performance computing expansion.

And after five straight weeks of outflows, U.S. spot Bitcoin ETFs have posted their strongest

performance since mid-January, recording $1.1 billion in net inflows in just three days.

Black Rock's Ibit led the charge, pulling in over $650 million, while Grayscale's GBTC saw its largest single-day inflow since

converting to an ETF as well. The data suggests real U.S. demand is returning. The Coinbase

premium index has finally turned positive after 40 days in the red, and total ETF holdings

have climbed to 1.29 million Bitcoin. As of this morning, Bitcoin slipped more than 3% to around $66,000.
