Sometimes the best Monday morning wake-up call is an acquisition rumor with a big number attached. That's exactly what Confluent Inc. (CFLT) shareholders got this morning, as shares rocketed higher in pre-market trading on news that could reshape the data infrastructure landscape.

According to a Sunday report from The Wall Street Journal, International Business Machines Corp (IBM) is in advanced discussions to acquire Confluent for roughly $11 billion. The deal would bring IBM a company that specializes in technology for managing real-time data streams—the kind increasingly used in large artificial intelligence models. In other words, IBM wants a piece of the infrastructure that makes modern AI tick.

The market clearly likes what it's hearing. Confluent shares jumped 31.8% to $30.49 in pre-market trading, reflecting investor optimism that this deal could actually happen.

But Confluent wasn't the only stock making waves before the opening bell. Here's a look at the other big movers in pre-market trading.

The Gainers

Some stocks came out swinging this morning, building on Friday's momentum or reacting to fresh catalysts:

• Treasure Global Inc (TGL) gained 128% to $58.00 in pre-market trading after already jumping 276% on Friday. Yes, you read those numbers correctly.

The Losers

Not everyone got good news over the weekend. Several stocks saw meaningful declines before the market even opened:

• Polyrizon Ltd (PLRZ) tumbled 22.1% to $10.20 in pre-market trading after declining 10% on Friday.
• Inspire Veterinary Partners Inc (IVP) declined 19.1% to $0.083 in pre-market trading.

• SMX (Security Matters) Public Limited Company (SMX) fell 17.2% to $275.00 in pre-market trading after jumping 135% on Friday. What goes up quickly can come down just as fast.
• Gulf Resources, Inc. (GURE) shares dipped 16.1% to $6.87 in pre-market trading after declining 4% on Friday.
• Wheeler Real Estate Investment Trust, Inc. (WHLR) dipped 16.1% to $5.35 in pre-market trading after surging 98% on Friday.

• iOThree Ltd (IOTR) fell 10.8% to $2.94 in pre-market trading after gaining 8% on Friday.

Pre-market trading often sets the tone for the regular session, but it's worth remembering that lower liquidity can amplify price swings. Still, when you see a 32% pop on acquisition news or triple-digit percentage moves in smaller-cap stocks, it's clear that Monday morning is starting with plenty of action.
