Looking Ahead
The Iran deal trajectory will be closely watched through Q3 — markets suggest traders see a narrow window before Oct/Nov geopolitical pressures complicate diplomacy. The BTC $70K June target is a key macro sentiment indicator; if achieved it would mark a decisive break above prior resistance. On the political side, the 2028 election markets are already drawing unprecedented volume for a race nearly 2.5 years away, suggesting significant early positioning by sophisticated traders.
